Archives For Apple

On both sides of the Atlantic, 2021 has seen legislative and regulatory proposals to mandate that various digital services be made interoperable with others. Several bills to do so have been proposed in Congress; the EU’s proposed Digital Markets Act would mandate interoperability in certain contexts for “gatekeeper” platforms; and the UK’s competition regulator will be given powers to require interoperability as part of a suite of “pro-competitive interventions” that are hoped to increase competition in digital markets.

The European Commission plans to require Apple to use USB-C charging ports on iPhones to allow interoperability among different chargers (to save, the Commission estimates, two grams of waste per-European per-year). Interoperability demands for forms of interoperability have been at the center of at least two major lawsuits: Epic’s case against Apple and a separate lawsuit against Apple by the app called Coronavirus Reporter. In July, a group of pro-intervention academics published a white paper calling interoperability “the ‘Super Tool’ of Digital Platform Governance.”

What is meant by the term “interoperability” varies widely. It can refer to relatively narrow interventions in which user data from one service is made directly portable to other services, rather than the user having to download and later re-upload it. At the other end of the spectrum, it could mean regulations to require virtually any vertical integration be unwound. (Should a Tesla’s engine be “interoperable” with the chassis of a Land Rover?) And in between are various proposals for specific applications of interoperability—some product working with another made by another company.

Why Isn’t Everything Interoperable?

The world is filled with examples of interoperability that arose through the (often voluntary) adoption of standards. Credit card companies oversee massive interoperable payments networks; screwdrivers are interoperable with screws made by other manufacturers, although different standards exist; many U.S. colleges accept credits earned at other accredited institutions. The containerization revolution in shipping is an example of interoperability leading to enormous efficiency gains, with a government subsidy to encourage the adoption of a single standard.

And interoperability can emerge over time. Microsoft Word used to be maddeningly non-interoperable with other word processors. Once OpenOffice entered the market, Microsoft patched its product to support OpenOffice files; Word documents now work slightly better with products like Google Docs, as well.

But there are also lots of things that could be interoperable but aren’t, like the Tesla motors that can’t easily be removed and added to other vehicles. The charging cases for Apple’s AirPods and Sony’s wireless earbuds could, in principle, be shaped to be interoperable. Medical records could, in principle, be standardized and made interoperable among healthcare providers, and it’s easy to imagine some of the benefits that could come from being able to plug your medical history into apps like MyFitnessPal and Apple Health. Keurig pods could, in principle, be interoperable with Nespresso machines. Your front door keys could, in principle, be made interoperable with my front door lock.

The reason not everything is interoperable like this is because interoperability comes with costs as well as benefits. It may be worth letting different earbuds have different designs because, while it means we sacrifice easy interoperability, we gain the ability for better designs to be brought to market and for consumers to have choice among different kinds. We may find that, while digital health records are wonderful in theory, the compliance costs of a standardized format might outweigh those benefits.

Manufacturers may choose to sell an expensive device with a relatively cheap upfront price tag, relying on consumer “lock in” for a stream of supplies and updates to finance the “full” price over time, provided the consumer likes it enough to keep using it.

Interoperability can remove a layer of security. I don’t want my bank account to be interoperable with any payments app, because it increases the risk of getting scammed. What I like about my front door lock is precisely that it isn’t interoperable with anyone else’s key. Lots of people complain about popular Twitter accounts being obnoxious, rabble-rousing, and stupid; it’s not difficult to imagine the benefits of a new, similar service that wanted everyone to start from the same level and so did not allow users to carry their old Twitter following with them.

There thus may be particular costs that prevent interoperability from being worth the tradeoff, such as that:

  1. It might be too costly to implement and/or maintain.
  2. It might prescribe a certain product design and prevent experimentation and innovation.
  3. It might add too much complexity and/or confusion for users, who may prefer not to have certain choices.
  4. It might increase the risk of something not working, or of security breaches.
  5. It might prevent certain pricing models that increase output.
  6. It might compromise some element of the product or service that benefits specifically from not being interoperable.

In a market that is functioning reasonably well, we should be able to assume that competition and consumer choice will discover the desirable degree of interoperability among different products. If there are benefits to making your product interoperable with others that outweigh the costs of doing so, that should give you an advantage over competitors and allow you to compete them away. If the costs outweigh the benefits, the opposite will happen—consumers will choose products that are not interoperable with each other.

In short, we cannot infer from the absence of interoperability that something is wrong, since we frequently observe that the costs of interoperability outweigh the benefits.

Of course, markets do not always lead to optimal outcomes. In cases where a market is “failing”—e.g., because competition is obstructed, or because there are important externalities that are not accounted for by the market’s prices—certain goods may be under-provided. In the case of interoperability, this can happen if firms struggle to coordinate upon a single standard, or because firms’ incentives to establish a standard are not aligned with the social optimum (i.e., interoperability might be optimal and fail to emerge, or vice versa).

But the analysis cannot stop here: just because a market might not be functioning well and does not currently provide some form of interoperability, we cannot assume that if it was functioning well that it would provide interoperability.

Interoperability for Digital Platforms

Since we know that many clearly functional markets and products do not provide all forms of interoperability that we could imagine them providing, it is perfectly possible that many badly functioning markets and products would still not provide interoperability, even if they did not suffer from whatever has obstructed competition or effective coordination in that market. In these cases, imposing interoperability would destroy value.

It would therefore be a mistake to assume that more interoperability in digital markets would be better, even if you believe that those digital markets suffer from too little competition. Let’s say, for the sake of argument, that Facebook/Meta has market power that allows it to keep its subsidiary WhatsApp from being interoperable with other competing services. Even then, we still would not know if WhatsApp users would want that interoperability, given the trade-offs.

A look at smaller competitors like Telegram and Signal, which we have no reason to believe have market power, demonstrates that they also are not interoperable with other messaging services. Signal is run by a nonprofit, and thus has little incentive to obstruct users for the sake of market power. Why does it not provide interoperability? I don’t know, but I would speculate that the security risks and technical costs of doing so outweigh the expected benefit to Signal’s users. If that is true, it seems strange to assume away the potential costs of making WhatsApp interoperable, especially if those costs may relate to things like security or product design.

Interoperability and Contact-Tracing Apps

A full consideration of the trade-offs is also necessary to evaluate the lawsuit that Coronavirus Reporter filed against Apple. Coronavirus Reporter was a COVID-19 contact-tracing app that Apple rejected from the App Store in March 2020. Its makers are now suing Apple for, they say, stifling competition in the contact-tracing market. Apple’s defense is that it only allowed COVID-19 apps from “recognised entities such as government organisations, health-focused NGOs, companies deeply credentialed in health issues, and medical or educational institutions.” In effect, by barring it from the App Store, and offering no other way to install the app, Apple denied Coronavirus Reporter interoperability with the iPhone. Coronavirus Reporter argues it should be punished for doing so.

No doubt, Apple’s decision did reduce competition among COVID-19 contact tracing apps. But increasing competition among COVID-19 contact-tracing apps via mandatory interoperability might have costs in other parts of the market. It might, for instance, confuse users who would like a very straightforward way to download their country’s official contact-tracing app. Or it might require access to certain data that users might not want to share, preferring to let an intermediary like Apple decide for them. Narrowing choice like this can be valuable, since it means individual users don’t have to research every single possible option every time they buy or use some product. If you don’t believe me, turn off your spam filter for a few days and see how you feel.

In this case, the potential costs of the access that Coronavirus Reporter wants are obvious: while it may have had the best contact-tracing service in the world, sorting it from other less reliable and/or scrupulous apps may have been difficult and the risk to users may have outweighed the benefits. As Apple and Facebook/Meta constantly point out, the security risks involved in making their services more interoperable are not trivial.

It isn’t competition among COVID-19 apps that is important, per se. As ever, competition is a means to an end, and maximizing it in one context—via, say, mandatory interoperability—cannot be judged without knowing the trade-offs that maximization requires. Even if we thought of Apple as a monopolist over iPhone users—ignoring the fact that Apple’s iPhones obviously are substitutable with Android devices to a significant degree—it wouldn’t follow that the more interoperability, the better.

A ‘Super Tool’ for Digital Market Intervention?

The Coronavirus Reporter example may feel like an “easy” case for opponents of mandatory interoperability. Of course we don’t want anything calling itself a COVID-19 app to have totally open access to people’s iPhones! But what’s vexing about mandatory interoperability is that it’s very hard to sort the sensible applications from the silly ones, and most proposals don’t even try. The leading U.S. House proposal for mandatory interoperability, the ACCESS Act, would require that platforms “maintain a set of transparent, third-party-accessible interfaces (including application programming interfaces) to facilitate and maintain interoperability with a competing business or a potential competing business,” based on APIs designed by the Federal Trade Commission.

The only nod to the costs of this requirement are provisions that further require platforms to set “reasonably necessary” security standards, and a provision to allow the removal of third-party apps that don’t “reasonably secure” user data. No other costs of mandatory interoperability are acknowledged at all.

The same goes for the even more substantive proposals for mandatory interoperability. Released in July 2021, “Equitable Interoperability: The ‘Super Tool’ of Digital Platform Governance” is co-authored by some of the most esteemed competition economists in the business. While it details obscure points about matters like how chat groups might work across interoperable chat services, it is virtually silent on any of the costs or trade-offs of its proposals. Indeed, the first “risk” the report identifies is that regulators might be too slow to impose interoperability in certain cases! It reads like interoperability has been asked what its biggest weaknesses are in a job interview.

Where the report does acknowledge trade-offs—for example, interoperability making it harder for a service to monetize its user base, who can just bypass ads on the service by using a third-party app that blocks them—it just says that the overseeing “technical committee or regulator may wish to create conduct rules” to decide.

Ditto with the objection that mandatory interoperability might limit differentiation among competitors – like, for example, how imposing the old micro-USB standard on Apple might have stopped us from getting the Lightning port. Again, they punt: “We recommend that the regulator or the technical committee consult regularly with market participants and allow the regulated interface to evolve in response to market needs.”

But if we could entrust this degree of product design to regulators, weighing the costs of a feature against its benefits, we wouldn’t need markets or competition at all. And the report just assumes away many other obvious costs: “​​the working hypothesis we use in this paper is that the governance issues are more of a challenge than the technical issues.” Despite its illustrious panel of co-authors, the report fails to grapple with the most basic counterargument possible: its proposals have costs as well as benefits, and it’s not straightforward to decide which is bigger than which.

Strangely, the report includes a section that “looks ahead” to “Google’s Dominance Over the Internet of Things.” This, the report says, stems from the company’s “market power in device OS’s [that] allows Google to set licensing conditions that position Google to maintain its monopoly and extract rents from these industries in future.” The report claims this inevitability can only be avoided by imposing interoperability requirements.

The authors completely ignore that a smart home interoperability standard has already been developed, backed by a group of 170 companies that include Amazon, Apple, and Google, as well as SmartThings, IKEA, and Samsung. It is open source and, in principle, should allow a Google Home speaker to work with, say, an Amazon Ring doorbell. In markets where consumers really do want interoperability, it can emerge without a regulator requiring it, even if some companies have apparent incentive not to offer it.

If You Build It, They Still Might Not Come

Much of the case for interoperability interventions rests on the presumption that the benefits will be substantial. It’s hard to know how powerful network effects really are in preventing new competitors from entering digital markets, and none of the more substantial reports cited by the “Super Tool” report really try.

In reality, the cost of switching among services or products is never zero. Simply pointing out that particular costs—such as network effect-created switching costs—happen to exist doesn’t tell us much. In practice, many users are happy to multi-home across different services. I use at least eight different messaging apps every day (Signal, WhatsApp, Twitter DMs, Slack, Discord, Instagram DMs, Google Chat, and iMessage/SMS). I don’t find it particularly costly to switch among them, and have been happy to adopt new services that seemed to offer something new. Discord has built a thriving 150-million-user business, despite these switching costs. What if people don’t actually care if their Instagram DMs are interoperable with Slack?

None of this is to argue that interoperability cannot be useful. But it is often overhyped, and it is difficult to do in practice (because of those annoying trade-offs). After nearly five years, Open Banking in the UK—cited by the “Super Tool” report as an example of what it wants for other markets—still isn’t really finished yet in terms of functionality. It has required an enormous amount of time and investment by all parties involved and has yet to deliver obvious benefits in terms of consumer outcomes, let alone greater competition among the current accounts that have been made interoperable with other services. (My analysis of the lessons of Open Banking for other services is here.) Phone number portability, which is also cited by the “Super Tool” report, is another example of how hard even simple interventions can be to get right.

The world is filled with cases where we could imagine some benefits from interoperability but choose not to have them, because the costs are greater still. None of this is to say that interoperability mandates can never work, but their benefits can be oversold, especially when their costs are ignored. Many of mandatory interoperability’s more enthusiastic advocates should remember that such trade-offs exist—even for policies they really, really like.

[Judge Douglas Ginsburg was invited to respond to the Beesley Lecture given by Andrea Coscelli, chief executive of the U.K. Competition and Markets Authority (CMA). Both the lecture and Judge Ginsburg’s response were broadcast by the BBC on Oct. 28, 2021. The text of Mr. Coscelli’s Beesley lecture is available on the CMA’s website. Judge Ginsburg’s response follows below.]

Thank you, Victoria, for the invitation to respond to Mr. Coscelli and his proposal for a legislatively founded Digital Markets Unit. Mr. Coscelli is one of the most talented, successful, and creative heads a competition agency has ever had. In the case of the DMU [ed., Digital Markets Unit], however, I think he has let hope triumph over experience and prudence. This is often the case with proposals for governmental reform: Indeed, it has a name, the Nirvana Fallacy, which comes from comparing the imperfectly functioning marketplace with the perfectly functioning government agency. Everything we know about the regulation of competition tells us the unintended consequences may dwarf the intended benefits and the result may be a less, not more, competitive economy. The precautionary principle counsels skepticism about such a major and inherently risky intervention.

Mr. Coscelli made a point in passing that highlights the difference in our perspectives: He said the SMS [ed., strategic market status] merger regime would entail “a more cautious standard of proof.” In our shared Anglo-American legal culture, a more cautious standard of proof means the government would intervene in fewer, not more, market activities; proof beyond a reasonable doubt in criminal cases is a more cautious standard than a mere preponderance of the evidence. I, too, urge caution, but of the traditional kind.

I will highlight five areas of concern with the DMU proposal.

I. Chilling Effects

The DMU’s ability to designate a firm as being of strategic market significance—or SMS—will place a potential cloud over innovative activity in far more sectors than Mr. Coscelli could mention in his lecture. He views the DMU’s reach as limited to a small number of SMS-designated firms; and that may prove true, but there is nothing in the proposal limiting DMU’s reach.

Indeed, the DMU’s authority to regulate digital markets is surely going to be difficult to confine. Almost every major retail activity or consumer-facing firm involves an increasingly significant digital component, particularly after the pandemic forced many more firms online. Deciding which firms the DMU should cover seems easy in theory, but will prove ever more difficult and cumbersome in practice as digital technology continues to evolve. For instance, now that money has gone digital, a bank is little more than a digital platform bringing together lenders (called depositors) and borrowers, much as Amazon brings together buyers and sellers; so, is every bank with market power and an entrenched position to be subject to rules and remedies laid down by the DMU as well as supervision by the bank regulators? Is Aldi in the crosshairs now that it has developed an online retail platform? Match.com, too? In short, the number of SMS firms will likely grow apace in the next few years.

II. SMS Designations Should Not Apply to the Whole Firm

The CMA’s proposal would apply each SMS designation firm-wide, even if the firm has market power in a single line of business. This will inhibit investment in further diversification and put an SMS firm at a competitive disadvantage across all its businesses.

Perhaps company-wide SMS designations could be justified if the unintended costs were balanced by expected benefits to consumers, but this will not likely be the case. First, there is little evidence linking consumer harm to lines of business in which large digital firms do not have market power. On the contrary, despite the discussion of Amazon’s supposed threat to competition, consumers enjoy lower prices from many more retailers because of the competitive pressure Amazon brings to bear upon them.

Second, the benefits Mr. Coscelli expects the economy to reap from faster government enforcement are, at best, a mixed blessing. The proposal, you see, reverses the usual legal norm, instead making interim relief the rule rather than the exception. If a firm appeals its SMS designation, then under the CMA’s proposal, the DMU’s SMS designations and pro-competition interventions, or PCIs, will not be stayed pending appeal, raising the prospect that a firm’s activities could be regulated for a significant period even though it was improperly designated. Even prevailing in the courts may be a Pyrrhic victory because opportunities will have slipped away. Making matters worse, the DMU’s designation of a firm as SMS will likely receive a high degree of judicial deference, so that errors may never be corrected.

III. The DMU Cannot Be Evidence-based Given its Goals and Objectives

The DMU’s stated goal is to “further the interests of consumers and citizens in digital markets by promoting competition and innovation.”[1] DMU’s objectives for developing codes of conduct are: fair trading, open choices, and trust and transparency.[2] Fairness, openness, trust, and transparency are all concepts that are difficult to define and probably impossible to quantify. Therefore, I fear Mr. Coscelli’s aspiration that the DMU will be an evidence-based, tailored, and predictable regime seem unrealistic. The CMA’s idea of “an evidence-based regime” seems destined to rely mostly upon qualitative conjecture about the potential for the code of conduct to set “rules of the game” that encourage fair trading, open choices, trust, and transparency. Even if the DMU commits to considering empirical evidence at every step of its process, these fuzzy, qualitative objectives will allow it to come to virtually any conclusion about how a firm should be regulated.

Implementing those broad goals also throws into relief the inevitable tensions among them. Some potential conflicts between DMU’s objectives for developing codes of conduct are clear from the EU’s experience. For example, one of the things DMU has considered already is stronger protection for personal data. The EU’s experience with the GDPR shows that data protection is costly and, like any costly requirement, tends to advantage incumbents and thereby discourage new entry. In other words, greater data protections may come at the expense of start-ups or other new entrants and the contribution they would otherwise have made to competition, undermining open choices in the name of data transparency.

Another example of tension is clear from the distinction between Apple’s iOS and Google’s Android ecosystems. They take different approaches to the trade-off between data privacy and flexibility in app development. Apple emphasizes consumer privacy at the expense of allowing developers flexibility in their design choices and offers its products at higher prices. Android devices have fewer consumer-data protections but allow app developers greater freedom to design their apps to satisfy users and are offered at lower prices. The case of Epic Games v. Apple put on display the purportedly pro-competitive arguments the DMU could use to justify shutting down Apple’s “walled garden,” whereas the EU’s GDPR would cut against Google’s open ecosystem with limited consumer protections. Apple’s model encourages consumer trust and adoption of a single, transparent model for app development, but Google’s model encourages app developers to choose from a broader array of design and payment options and allows consumers to choose between the options; no matter how the DMU designs its code of conduct, it will be creating winners and losers at the cost of either “open choices” or “trust and transparency.” As experience teaches is always the case, it is simply not possible for an agency with multiple goals to serve them all at the same time. The result is an unreviewable discretion to choose among them ad hoc.

Finally, notice that none of the DMU’s objectives—fair trading, open choices, and trust and transparency—revolves around quantitative evidence; at bottom, these goals are not amenable to the kind of rigor Mr. Coscelli hopes for.

IV. Speed of Proposals

Mr. Coscelli has emphasized the slow pace of competition law matters; while I empathize, surely forcing merging parties to prove a negative and truncating their due process rights is not the answer.

As I mentioned earlier, it seems a more cautious standard of proof to Mr. Coscelli is one in which an SMS firm’s proposal to acquire another firm is presumed, or all but presumed, to be anticompetitive and unlawful. That is, the DMU would block the transaction unless the firms can prove their deal would not be anticompetitive—an extremely difficult task. The most self-serving version of the CMA’s proposal would require it to prove only that the merger poses a “realistic prospect” of lessening competition, which is vague, but may in practice be well below a 50% chance. Proving that the merged entity does not harm competition will still require a predictive forward-looking assessment with inherent uncertainty, but the CMA wants the costs of uncertainty placed upon firms, rather than it. Given the inherent uncertainty in merger analysis, the CMA’s proposal would pose an unprecedented burden of proof on merging parties.

But it is not only merging parties the CMA would deprive of due process; the DMU’s so-called pro-competitive interventions, or PCI, SMS designations, and code-of-conduct requirements generally would not be stayed pending appeal. Further, an SMS firm could overturn the CMA’s designation only if it could overcome substantial deference to the DMU’s fact-finding. It is difficult to discern, then, the difference between agency decisions and final orders.

The DMU would not have to show or even assert an extraordinary need for immediate relief. This is the opposite of current practice in every jurisdiction with which I am familiar.  Interim orders should take immediate effect only in exceptional circumstances, when there would otherwise be significant and irreversible harm to consumers, not in the ordinary course of agency decision making.

V. Antitrust Is Not Always the Answer

Although one can hardly disagree with Mr. Coscelli’s premise that the digital economy raises new legal questions and practical challenges, it is far from clear that competition law is the answer to them all. Some commentators of late are proposing to use competition law to solve consumer protection and even labor market problems. Unfortunately, this theme also recurs in Mr. Coscelli’s lecture. He discusses concerns with data privacy and fair and reasonable contract terms, but those have long been the province of consumer protection and contract law; a government does not need to step in and regulate all realms of activity by digital firms and call it competition law. Nor is there reason to confine needed protections of data privacy or fair terms of use to SMS firms.

Competition law remedies are sometimes poorly matched to the problems a government is trying to correct. Mr. Coscelli discusses the possibility of strong interventions, such as forcing the separation of a platform from its participation in retail markets; for example, the DMU could order Amazon to spin off its online business selling and shipping its own brand of products. Such powerful remedies can be a sledgehammer; consider forced data sharing or interoperability to make it easier for new competitors to enter. For example, if Apple’s App Store is required to host all apps submitted to it in the interest of consumer choice, then Apple loses its ability to screen for security, privacy, and other consumer benefits, as its refusal   to deal is its only way to prevent participation in its store. Further, it is not clear consumers want Apple’s store to change; indeed, many prefer Apple products because of their enhanced security.

Forced data sharing would also be problematic; the hiQ v. LinkedIn case in the United States should serve as a cautionary tale. The trial court granted a preliminary injunction forcing LinkedIn to allow hiQ to scrape its users’ profiles while the suit was ongoing. LinkedIn ultimately won the suit because it did not have market power, much less a monopoly, in any relevant market. The court concluded each theory of anticompetitive conduct was implausible, but meanwhile LinkedIn had been forced to allow hiQ to scrape its data for an extended period before the final decision. There is no simple mechanism to “unshare” the data now that LinkedIn has prevailed. This type of case could be common under the CMA proposal because the DMU’s orders will go into immediate effect.

There is potentially much redeeming power in the Digital Regulation Co-operation Forum as Mr. Coscelli described it, but I take a different lesson from this admirable attempt to coordinate across agencies: Perhaps it is time to look beyond antitrust to solve problems that are not based upon market power. As the DRCF highlights, there are multiple agencies with overlapping authority in the digital market space. ICO and Ofcom each have authority to take action against a firm that disseminates fake news or false advertisements. Mr. Coscelli says it would be too cumbersome to take down individual bad actors, but, if so, then the solution is to adopt broader consumer protection rules, not apply an ill-fitting set of competition law rules. For example, the U.K. could change its notice-and-takedown rules to subject platforms to strict liability if they host fake news, even without knowledge that they are doing so, or perhaps only if they are negligent in discharging their obligation to police against it.

Alternatively, the government could shrink the amount of time platforms have to take down information; France gives platforms only about an hour to remove harmful information. That sort of solution does not raise the same prospect of broadly chilling market activity, but still addresses one of the concerns Mr. Coscelli raises with digital markets.

In sum, although Mr. Coscelli is of course correct that competition authorities and governments worldwide are considering whether to adopt broad reforms to their competition laws, the case against broadening remains strong. Instead of relying upon the self-corrective potential of markets, which is admittedly sometimes slower than anyone would like, the CMA assumes markets need regulation until firms prove otherwise. Although clearly well-intentioned, the DMU proposal is in too many respects not met to the task of protecting competition in digital markets; at worst, it will inhibit innovation in digital markets to the point of driving startups and other innovators out of the U.K.

Why do digital industries routinely lead to one company having a very large share of the market (at least if one defines markets narrowly)? To anyone familiar with competition policy discussions, the answer might seem obvious: network effects, scale-related economies, and other barriers to entry lead to winner-take-all dynamics in platform industries. Accordingly, it is that believed the first platform to successfully unlock a given online market enjoys a determining first-mover advantage.

This narrative has become ubiquitous in policymaking circles. Thinking of this sort notably underpins high-profile reports on competition in digital markets (here, here, and here), as well ensuing attempts to regulate digital platforms, such as the draft American Innovation and Choice Online Act and the EU’s Digital Markets Act.

But are network effects and the like the only ways to explain why these markets look like this? While there is no definitive answer, scholars routinely overlook an alternative explanation that tends to undercut the narrative that tech markets have become non-contestable.

The alternative model is simple: faced with zero prices and the almost complete absence of switching costs, users have every reason to join their preferred platform. If user preferences are relatively uniform and one platform has a meaningful quality advantage, then there is every reason to expect that most consumers will all join the same one—even though the market remains highly contestable. On the other side of the equation, because platforms face very few capacity constraints, there are few limits to a given platform’s growth. As will be explained throughout this piece, this intuition is as old as economics itself.

The Bertrand Paradox

In 1883, French mathematician Joseph Bertrand published a powerful critique of two of the most high-profile economic thinkers of his time: the late Antoine Augustin Cournot and Léon Walras (it would be another seven years before Alfred Marshall published his famous principles of economics).

Bertrand criticized several of Cournot and Walras’ widely accepted findings. This included Cournot’s conclusion that duopoly competition would lead to prices above marginal cost—or, in other words, that duopolies were imperfectly competitive.

By reformulating the problem slightly, Bertand arrived at the opposite conclusion. He argued that each firm’s incentive to undercut its rival would ultimately lead to marginal cost pricing, and one seller potentially capturing the entire market:

There is a decisive objection [to Cournot’s model]: According to his hypothesis, no [supracompetitive] equilibrium is possible. There is no limit to price decreases; whatever the joint price being charged by firms, a competitor could always undercut this price and, with few exceptions, attract all consumers. If the competitor is allowed to get away with this [i.e. the rival does not react], it will double its profits.

This result is mainly driven by the assumption that, unlike in Cournot’s model, firms can immediately respond to their rival’s chosen price/quantity. In other words, Bertrand implicitly framed the competitive process as price competition, rather than quantity competition (under price competition, firms do not face any capacity constraints and they cannot commit to producing given quantities of a good):

If Cournot’s calculations mask this result, it is because of a remarkable oversight. Referring to them as D and D’, Cournot deals with the quantities sold by each of the two competitors and treats them as independent variables. He assumes that if one were to change by the will of one of the two sellers, the other one could remain fixed. The opposite is evidently true.

This later came to be known as the “Bertrand paradox”—the notion that duopoly-market configurations can produce the same outcome as perfect competition (i.e., P=MC).

But while Bertrand’s critique was ostensibly directed at Cournot’s model of duopoly competition, his underlying point was much broader. Above all, Bertrand seemed preoccupied with the notion that expressing economic problems mathematically merely gives them a veneer of accuracy. In that sense, he was one of the first economists (at least to my knowledge) to argue that the choice of assumptions has a tremendous influence on the predictions of economic models, potentially rendering them unreliable:

On other occasions, Cournot introduces assumptions that shield his reasoning from criticism—scholars can always present problems in a way that suits their reasoning.

All of this is not to say that Bertrand’s predictions regarding duopoly competition necessarily hold in real-world settings; evidence from experimental settings is mixed. Instead, the point is epistemological. Bertrand’s reasoning was groundbreaking because he ventured that market structures are not the sole determinants of consumer outcomes. More broadly, he argued that assumptions regarding the competitive process hold significant sway over the results that a given model may produce (and, as a result, over normative judgements concerning the desirability of given market configurations).

The Theory of Contestable Markets

Bertrand is certainly not the only economist to have suggested market structures alone do not determine competitive outcomes. In the early 1980s, William Baumol (and various co-authors) went one step further. Baumol argued that, under certain conditions, even monopoly market structures could deliver perfectly competitive outcomes. This thesis thus rejected the Structure-Conduct-Performance (“SCP”) Paradigm that dominated policy discussions of the time.

Baumol’s main point was that industry structure is not the main driver of market “contestability,” which is the key determinant of consumer outcomes. In his words:

In the limit, when entry and exit are completely free, efficient incumbent monopolists and oligopolists may in fact be able to prevent entry. But they can do so only by behaving virtuously, that is, by offering to consumers the benefits which competition would otherwise bring. For every deviation from good behavior instantly makes them vulnerable to hit-and-run entry.

For instance, it is widely accepted that “perfect competition” leads to low prices because firms are price-takers; if one does not sell at marginal cost, it will be undercut by rivals. Observers often assume this is due to the number of independent firms on the market. Baumol suggests this is wrong. Instead, the result is driven by the sanction that firms face for deviating from competitive pricing.

In other words, numerous competitors are a sufficient, but not necessary condition for competitive pricing. Monopolies can produce the same outcome when there is a present threat of entry and an incumbent’s deviation from competitive pricing would be sanctioned. This is notably the case when there are extremely low barriers to entry.

Take this hypothetical example from the world of cryptocurrencies. It is largely irrelevant to a user whether there are few or many crypto exchanges on which to trade coins, nonfungible tokens (NFTs), etc. What does matter is that there is at least one exchange that meets one’s needs in terms of both price and quality of service. This could happen because there are many competing exchanges, or because a failure to meet my needs by the few (or even one) exchange that does exist would attract the entry of others to which I could readily switch—thus keeping the behavior of the existing exchanges in check.

This has far-reaching implications for antitrust policy, as Baumol was quick to point out:

This immediately offers what may be a new insight on antitrust policy. It tells us that a history of absence of entry in an industry and a high concentration index may be signs of virtue, not of vice. This will be true when entry costs in our sense are negligible.

Given what precedes, Baumol surmised that industry structure must be driven by endogenous factors—such as firms’ cost structures—rather than the intensity of competition that they face. For instance, scale economies might make monopoly (or another structure) the most efficient configuration in some industries. But so long as rivals can sanction incumbents for failing to compete, the market remains contestable. Accordingly, at least in some industries, both the most efficient and the most contestable market configuration may entail some level of concentration.

To put this last point in even more concrete terms, online platform markets may have features that make scale (and large market shares) efficient. If so, there is every reason to believe that competition could lead to more, not less, concentration. 

How Contestable Are Digital Markets?

The insights of Bertrand and Baumol have important ramifications for contemporary antitrust debates surrounding digital platforms. Indeed, it is critical to ascertain whether the (relatively) concentrated market structures we see in these industries are a sign of superior efficiency (and are consistent with potentially intense competition), or whether they are merely caused by barriers to entry.

The barrier-to-entry explanation has been repeated ad nauseam in recent scholarly reports, competition decisions, and pronouncements by legislators. There is thus little need to restate that thesis here. On the other hand, the contestability argument is almost systematically ignored.

Several factors suggest that online platform markets are far more contestable than critics routinely make them out to be.

First and foremost, consumer switching costs are extremely low for most online platforms. To cite but a few examples: Changing your default search engine requires at most a couple of clicks; joining a new social network can be done by downloading an app and importing your contacts to the app; and buying from an alternative online retailer is almost entirely frictionless, thanks to intermediaries such as PayPal.

These zero or near-zero switching costs are compounded by consumers’ ability to “multi-home.” In simple terms, joining TikTok does not require users to close their Facebook account. And the same applies to other online services. As a result, there is almost no opportunity cost to join a new platform. This further reduces the already tiny cost of switching.

Decades of app development have greatly improved the quality of applications’ graphical user interfaces (GUIs), to such an extent that costs to learn how to use a new app are mostly insignificant. Nowhere is this more apparent than for social media and sharing-economy apps (it may be less true for productivity suites that enable more complex operations). For instance, remembering a couple of intuitive swipe motions is almost all that is required to use TikTok. Likewise, ridesharing and food-delivery apps merely require users to be familiar with the general features of other map-based applications. It is almost unheard of for users to complain about usability—something that would have seemed impossible in the early 21st century, when complicated interfaces still plagued most software.

A second important argument in favor of contestability is that, by and large, online platforms face only limited capacity constraints. In other words, platforms can expand output rapidly (though not necessarily costlessly).

Perhaps the clearest example of this is the sudden rise of the Zoom service in early 2020. As a result of the COVID pandemic, Zoom went from around 10 million daily active users in early 2020 to more than 300 million by late April 2020. Despite being a relatively data-intensive service, Zoom did not struggle to meet this new demand from a more than 30-fold increase in its user base. The service never had to turn down users, reduce call quality, or significantly increase its price. In short, capacity largely followed demand for its service. Online industries thus seem closer to the Bertrand model of competition, where the best platform can almost immediately serve any consumers that demand its services.

Conclusion

Of course, none of this should be construed to declare that online markets are perfectly contestable. The central point is, instead, that critics are too quick to assume they are not. Take the following examples.

Scholars routinely cite the putatively strong concentration of digital markets to argue that big tech firms do not face strong competition, but this is a non sequitur. As Bertrand and Baumol (and others) show, what matters is not whether digital markets are concentrated, but whether they are contestable. If a superior rival could rapidly gain user traction, this alone will discipline the behavior of incumbents.

Markets where incumbents do not face significant entry from competitors are just as consistent with vigorous competition as they are with barriers to entry. Rivals could decline to enter either because incumbents have aggressively improved their product offerings or because they are shielded by barriers to entry (as critics suppose). The former is consistent with competition, the latter with monopoly slack.

Similarly, it would be wrong to presume, as many do, that concentration in online markets is necessarily driven by network effects and other scale-related economies. As ICLE scholars have argued elsewhere (here, here and here), these forces are not nearly as decisive as critics assume (and it is debatable that they constitute barriers to entry).

Finally, and perhaps most importantly, this piece has argued that many factors could explain the relatively concentrated market structures that we see in digital industries. The absence of switching costs and capacity constraints are but two such examples. These explanations, overlooked by many observers, suggest digital markets are more contestable than is commonly perceived.

In short, critics’ failure to meaningfully grapple with these issues serves to shape the prevailing zeitgeist in tech-policy debates. Cournot and Bertrand’s intuitions about oligopoly competition may be more than a century old, but they continue to be tested empirically. It is about time those same standards were applied to tech-policy debates.

A bipartisan group of senators unveiled legislation today that would dramatically curtail the ability of online platforms to “self-preference” their own services—for example, when Apple pre-installs its own Weather or Podcasts apps on the iPhone, giving it an advantage that independent apps don’t have. The measure accompanies a House bill that included similar provisions, with some changes.

1. The Senate bill closely resembles the House version, and the small improvements will probably not amount to much in practice.

The major substantive changes we have seen between the House bill and the Senate version are:

  1. Violations in Section 2(a) have been modified to refer only to conduct that “unfairly” preferences, limits, or discriminates between the platform’s products and others, and that “materially harm[s] competition on the covered platform,” rather than banning all preferencing, limits, or discrimination.
  2. The evidentiary burden required throughout the bill has been changed from  “clear and convincing” to a “preponderance of evidence” (in other words, greater than 50%).
  3. An affirmative defense has been added to permit a platform to escape liability if it can establish that challenged conduct that “was narrowly tailored, was nonpretextual, and was necessary to… maintain or enhance the core functionality of the covered platform.”
  4. The minimum market capitalization for “covered platforms” has been lowered from $600 billion to $550 billion.
  5. The Senate bill would assess fines of 15% of revenues from the period during which the conduct occurred, in contrast with the House bill, which set fines equal to the greater of either 15% of prior-year revenues or 30% of revenues from the period during which the conduct occurred.
  6. Unlike the House bill, the Senate bill does not create a private right of action. Only the U.S. Justice Department (DOJ), Federal Trade Commission (FTC), and state attorneys-generals could bring enforcement actions on the basis of the bill.

Item one here certainly mitigates the most extreme risks of the House bill, which was drafted, bizarrely, to ban all “preferencing” or “discrimination” by platforms. If that were made law, it could literally have broken much of the Internet. The softened language reduces that risk somewhat.

However, Section 2(b), which lists types of conduct that would presumptively establish a violation under Section 2(a), is largely unchanged. As outlined here, this would amount to a broad ban on a wide swath of beneficial conduct. And “unfair” and “material” are notoriously slippery concepts. As a practical matter, their inclusion here may not significantly alter the course of enforcement under the Senate legislation from what would ensue under the House version.

Item three, which allows challenged conduct to be defended if it is “necessary to… maintain or enhance the core functionality of the covered platform,” may also protect some conduct. But because the bill requires companies to prove that challenged conduct is not only beneficial, but necessary to realize those benefits, it effectively implements a “guilty until proven innocent” standard that is likely to prove impossible to meet. The threat of permanent injunctions and enormous fines will mean that, in many cases, companies simply won’t be able to justify the expense of endeavoring to improve even the “core functionality” of their platforms in any way that could trigger the bill’s liability provisions. Thus, again, as a practical matter, the difference between the Senate and House bills may be only superficial.

The effect of this will likely be to diminish product innovation in these areas, because companies could not know in advance whether the benefits of doing so would be worth the legal risk. We have previously highlighted existing conduct that may be lost if a bill like this passes, such as pre-installation of apps or embedding maps and other “rich” results in boxes on search engine results pages. But the biggest loss may be things we don’t even know about yet, that just never happen because the reward from experimentation is not worth the risk of being found to be “discriminating” against a competitor.

We dove into the House bill in Breaking Down the American Choice and Innovation Online Act and Breaking Down House Democrats’ Forthcoming Competition Bills.

2. The prohibition on “unfair self-preferencing” is vague and expansive and will make Google, Amazon, Facebook, and Apple’s products worse. Consumers don’t want digital platforms to be dumb pipes, or to act like a telephone network or sewer system. The Internet is filled with a superabundance of information and options, as well as a host of malicious actors. Good digital platforms act as middlemen, sorting information in useful ways and taking on some of the risk that exists when, inevitably, we end up doing business with untrustworthy actors.

When users have the choice, they tend to prefer platforms that do quite a bit of “discrimination”—that is, favoring some sellers over others, or offering their own related products or services through the platform. Most people prefer Amazon to eBay because eBay is chaotic and riskier to use.

Competitors that decry self-preferencing by the largest platforms—integrating two different products with each other, like putting a maps box showing only the search engine’s own maps on a search engine results page—argue that the conduct is enabled only by a platform’s market dominance and does not benefit consumers.

Yet these companies often do exactly the same thing in their own products, regardless of whether they have market power. Yelp includes a map on its search results page, not just restaurant listings. DuckDuckGo does the same. If these companies offer these features, it is presumably because they think their users want such results. It seems perfectly plausible that Google does the same because it thinks its users—literally the same users, in most cases—also want them.

Fundamentally, and as we discuss in Against the Vertical Disrcimination Presumption, there is simply no sound basis to enact such a bill (even in a slightly improved version):

The notion that self-preferencing by platforms is harmful to innovation is entirely speculative. Moreover, it is flatly contrary to a range of studies showing that the opposite is likely true. In reality, platform competition is more complicated than simple theories of vertical discrimination would have it, and there is certainly no basis for a presumption of harm.

We discussed self-preferencing further in Platform Self-Preferencing Can Be Good for Consumers and Even Competitors, and showed that platform “discrimination” is often what consumers want from digital platforms in On the Origin of Platforms: An Evolutionary Perspective.

3. The bill massively empowers an FTC that seems intent to use antitrust to achieve political goals. The House bill would enable competitors to pepper covered platforms with frivolous lawsuits. The bill’s sponsors presumably hope that removing the private right of action will help to avoid that. But the bill still leaves intact a much more serious risk to the rule of law: the bill’s provisions are so broad that federal antitrust regulators will have enormous discretion over which cases they take.

This means that whoever is running the FTC and DOJ will be able to threaten covered platforms with a broad array of lawsuits, potentially to influence or control their conduct in other, unrelated areas. While some supporters of the bill regard this as a positive, most antitrust watchers would greet this power with much greater skepticism. Fundamentally, both bills grant antitrust enforcers wildly broad powers to pursue goals unrelated to competition. FTC Chair Lina Khan has, for example, argued that “the dispersion of political and economic control” ought to be antitrust’s goal. Commissioner Rebecca Kelly-Slaughter has argued that antitrust should be “antiracist”.

Whatever the desirability of these goals, the broad discretionary authority the bills confer on the antitrust agencies means that individual commissioners may have significantly greater scope to pursue the goals that they believe to be right, rather than Congress.

See discussions of this point at What Lina Khan’s Appointment Means for the House Antitrust Bills, Republicans Should Tread Carefully as They Consider ‘Solutions’ to Big Tech, The Illiberal Vision of Neo-Brandeisian Antitrust, and Alden Abbott’s discussion of FTC Antitrust Enforcement and the Rule of Law.

4. The bill adopts European principles of competition regulation. These are, to put it mildly, not obviously conducive to the sort of innovation and business growth that Americans may expect. Europe has no tech giants of its own, a condition that shows little sign of changing. Apple, alone, is worth as much as the top 30 companies in Germany’s DAX index, and the top 40 in France’s CAC index. Landmark European competition cases have seen Google fined for embedding Shopping results in the Search page—not because it hurt consumers, but because it hurt competing pricecomparison websites.

A fundamental difference between American and European competition regimes is that the U.S. system is far more friendly to businesses that obtain dominant market positions because they have offered better products more cheaply. Under the American system, successful businesses are normally given broad scope to charge high prices and refuse to deal with competitors. This helps to increase the rewards and incentive to innovate and invest in order to obtain that strong market position. The European model is far more burdensome.

The Senate bill adopts a European approach to refusals to deal—the same approach that led the European Commission to fine Microsoft for including Windows Media Player with Windows—and applies it across Big Tech broadly. Adopting this kind of approach may end up undermining elements of U.S. law that support innovation and growth.

For more, see How US and EU Competition Law Differ.

5. The proposals are based on a misunderstanding of the state of competition in the American economy, and of antitrust enforcement. It is widely believed that the U.S. economy has seen diminished competition. This is mistaken, particularly with respect to digital markets. Apparent rises in market concentration and profit margins disappear when we look more closely: local-level concentration is falling even as national-level concentration is rising, driven by more efficient chains setting up more stores in areas that were previously served by only one or two firms.

And markup rises largely disappear after accounting for fixed costs like R&D and marketing.

Where profits are rising, in areas like manufacturing, it appears to be mainly driven by increased productivity, not higher prices. Real prices have not risen in line with markups. Where profitability has increased, it has been mainly driven by falling costs.

Nor have the number of antitrust cases brought by federal antitrust agencies fallen. The likelihood of a merger being challenged more than doubled between 1979 and 2017. And there is little reason to believe that the deterrent effect of antitrust has weakened. Many critics of Big Tech have decided that there must be a problem and have worked backwards from that conclusion, selecting whatever evidence supports it and ignoring the evidence that does not. The consequence of such motivated reasoning is bills like this.

See Geoff’s April 2020 written testimony to the House Judiciary Investigation Into Competition in Digital Markets here.

Still from Squid Game, Netflix and Siren Pictures Inc., 2021

Recent commentary on the proposed merger between WarnerMedia and Discovery, as well as Amazon’s acquisition of MGM, often has included the suggestion that the online content-creation and video-streaming markets are excessively consolidated, or that they will become so absent regulatory intervention. For example, in a recent letter to the U.S. Justice Department (DOJ), the American Antitrust Institute and Public Knowledge opine that:

Slow and inadequate oversight risks the streaming market going the same route as cable—where consumers have little power, few options, and where consolidation and concentration reign supreme. A number of threats to competition are clear, as discussed in this section, including: (1) market power issues surrounding content and (2) the role of platforms in “gatekeeping” to limit competition.

But the AAI/PK assessment overlooks key facts about the video-streaming industry, some of which suggest that, if anything, these markets currently suffer from too much fragmentation.

The problem is well-known: any individual video-streaming service will offer only a fraction of the content that viewers want, but budget constraints limit the number of services that a household can afford to subscribe to. It may be counterintuitive, but consolidation in the market for video-streaming can solve both problems at once.

One subscription is not enough

Surveys find that U.S. households currently maintain, on average, four video-streaming subscriptions. This explains why even critics concede that a plethora of streaming services compete for consumer eyeballs. For instance, the AAI and PK point out that:

Today, every major media company realizes the value of streaming and a bevy of services have sprung up to offer different catalogues of content.

These companies have challenged the market leader, Netflix and include: Prime Video (2006), Hulu (2007), Paramount+ (2014), ESPN+ (2018), Disney+ (2019), Apple TV+ (2019), HBO Max (2020), Peacock (2020), and Discovery+ (2021).

With content scattered across several platforms, multiple subscriptions are the only way for households to access all (or most) of the programs they desire. Indeed, other than price, library sizes and the availability of exclusive content are reportedly the main drivers of consumer purchase decisions.

Of course, there is nothing inherently wrong with the current equilibrium in which consumers multi-home across multiple platforms. One potential explanation is demand for high-quality exclusive content, which requires tremendous investment to develop and promote. Production costs for TV series routinely run in the tens of millions of dollars per episode (see here and here). Economic theory predicts these relationship-specific investments made by both producers and distributors will cause producers to opt for exclusive distribution or vertical integration. The most sought-after content is thus exclusive to each platform. In other words, exclusivity is likely the price that users must pay to ensure that high-quality entertainment continues to be produced.

But while this paradigm has many strengths, the ensuing fragmentation can be detrimental to consumers, as this may lead to double marginalization or mundane issues like subscription fatigue. Consolidation can be a solution to both.

Substitutes, complements, or unrelated?

As Hal Varian explains in his seminal book, the relationship between two goods can range among three extremes: perfect substitutes (i.e., two goods are perfectly interchangeable); perfect complements (i.e., there is no value to owning one good without the other); or goods that exist in independent markets (i.e., the price of one good does not affect demand for the other).

These distinctions are critical when it comes to market concentration. All else equal—which is obviously not the case in reality—increased concentration leads to lower prices for complements, and higher prices for substitutes. Finally, if demand for two goods is unrelated, then bringing them under common ownership should not affect their price.

To at least some extent, streaming services should be seen as complements rather than substitutes—or, at least, as services with unrelated demand. If they were perfect substitutes, consumers would be indifferent between two Netflix subscriptions or one Netflix plan and one Amazon Prime plan. That is obviously not the case. Nor are they perfect complements, which would mean that Netflix is worthless without Amazon Prime, Disney+, and other services.

However, there is reason to believe there exists some complementarity between streaming services, or at least that demand for them is independent. Most consumers subscribe to multiple services, and almost no one subscribes to the same service twice:

SOURCE: Finance Buzz

This assertion is also supported by the ubiquitous bundling of subscriptions in the cable distribution industry, which also has recently been seen in video-streaming markets. For example, in the United States, Disney+ can be purchased in a bundle with Hulu and ESPN+.

The key question is: is each service more valuable, less valuable, or as valuable in isolation than they are when bundled? If households place some additional value on having a complete video offering (one that includes child entertainment, sports, more mature content, etc.), and if they value the convenience of accessing more of their content via a single app, then we can infer these services are to some extent complementary.

Finally, it is worth noting that any complementarity between these services would be largely endogenous. If the industry suddenly switched to a paradigm of non-exclusive content—as is broadly the case for audio streaming—the above analysis would be altered (though, as explained above, such a move would likely be detrimental to users). Streaming services would become substitutes if they offered identical catalogues.

In short, the extent to which streaming services are complements ultimately boils down to an empirical question that may fluctuate with industry practices. As things stand, there is reason to believe that these services feature some complementarities, or at least that demand for them is independent. In turn, this suggests that further consolidation within the industry would not lead to price increases and may even reduce them.

Consolidation can enable price discrimination

It is well-established that bundling entertainment goods can enable firms to better engage in price discrimination, often increasing output and reducing deadweight loss in the process.

Take George Stigler’s famous explanation for the practice of “block booking,” in which movie studios sold multiple films to independent movie theatres as a unit. Stigler assumes the underlying goods are neither substitutes nor complements:

Stigler, George J. (1963) “United States v. Loew’s Inc.: A Note on Block-Booking,” Supreme Court Review: Vol. 1963 : No. 1 , Article 2.

The upshot is that, when consumer tastes for content are idiosyncratic—as is almost certainly the case for movies and television series, movies—it can counterintuitively make sense to sell differing content as a bundle. In doing so, the distributor avoids pricing consumers out of the content upon which they place a lower value. Moreover, this solution is more efficient than price discriminating on an unbundled basis, as doing so would require far more information on the seller’s part and would be vulnerable to arbitrage.

In short, bundling enables each consumer to access a much wider variety of content. This, in turn, provides a powerful rationale for mergers in the video-streaming space—particularly where they can bring together varied content libraries. Put differently, it cuts in favor of more, not less, concentration in video-streaming markets (at least, up to a certain point).

Finally, a wide array of scale-related economies further support the case for concentration in video-streaming markets. These include potential economies of scale, network effects, and reduced transaction costs.

The simplest of these ideas is that the cost of video streaming may decrease at the margin (i.e., serving each marginal viewer might be cheaper than the previous one). In other words, mergers of video-streaming services mayenable platforms to operate at a more efficient scale. There has notably been some discussion of whether Netflix benefits from scale economies of this sort. But this is, of course, ultimately an empirical question. As I have written with Geoffrey Manne, we should not assume that this is the case for all digital platforms, or that these increasing returns are present at all ranges of output.

Likewise, the fact that content can earn greater revenues by reaching a wider audience (or a greater number of small niches) may increase a producer’s incentive to create high-quality content. For example, Netflix’s recent hit series Squid Game reportedly cost $16.8 million to produce a total of nine episodes. This is significant for a Korean-language thriller. These expenditures were likely only possible because of Netflix’s vast network of viewers. Video-streaming mergers can jump-start these effects by bringing previously fragmented audiences onto a single platform.

Finally, operating at a larger scale may enable firms and consumers to economize on various transaction and search costs. For instance, consumers don’t need to manage several subscriptions, and searching for content is easier within a single ecosystem.

Conclusion

In short, critics could hardly be more wrong in assuming that consolidation in the video-streaming industry will necessarily harm consumers. To the contrary, these mergers should be presumptively welcomed because, to a first approximation, they are likely to engender lower prices and reduce deadweight loss.

Critics routinely draw parallels between video streaming and the consolidation that previously moved through the cable industry. They suggest these events as evidence that consolidation was (and still is) inefficient and exploitative of consumers. As AAI and PK frame it:

Moreover, given the broader competition challenges that reside in those markets, and the lessons learned from a failure to ensure competition in the traditional MVPD markets, enforcers should be particularly vigilant.

But while it might not have been ideal for all consumers, the comparatively laissez-faire approach to competition in the cable industry arguably facilitated the United States’ emergence as a global leader for TV programming. We are now witnessing what appears to be a similar trend in the online video-streaming market.

This is mostly a good thing. While a single streaming service might not be the optimal industry configuration from a welfare standpoint, it would be equally misguided to assume that fragmentation necessarily benefits consumers. In fact, as argued throughout this piece, there are important reasons to believe that the status quo—with at least 10 significant players—is too fragmented and that consumers would benefit from additional consolidation.

The dystopian novel is a powerful literary genre. It has given us such masterpieces as Nineteen Eighty-Four, Brave New World, and Fahrenheit 451. Though these novels often shed light on the risks of contemporary society and the zeitgeist of the era in which they were written, they also almost always systematically overshoot the mark (intentionally or not) and severely underestimate the radical improvements that stem from the technologies (or other causes) that they fear.

But dystopias are not just a literary phenomenon; they are also a powerful force in policy circles. This is epitomized by influential publications such as The Club of Rome’s 1972 report The Limits of Growth, whose dire predictions of Malthusian catastrophe have largely failed to materialize.

In an article recently published in the George Mason Law Review, we argue that contemporary antitrust scholarship and commentary is similarly afflicted by dystopian thinking. In that respect, today’s antitrust pessimists have set their sights predominantly on the digital economy—”Big Tech” and “Big Data”—in the process of alleging a vast array of potential harms.

Scholars have notably argued that the data created and employed by the digital economy produces network effects that inevitably lead to tipping and to more concentrated markets (e.g., here and here). In other words, firms will allegedly accumulate insurmountable data advantages and thus thwart competitors for extended periods of time.

Some have gone so far as to argue that this threatens the very fabric of western democracy. For instance, parallels between the novel Nineteen Eighty-Four and the power of large digital platforms were plain to see when Epic Games launched an antitrust suit against Apple and its App Store in August 2020. The gaming company released a short video clip parodying Apple’s famous “1984” ad (which, upon its release, was itself widely seen as a critique of the tech incumbents of the time). Similarly, a piece in the New Statesman—titled “Slouching Towards Dystopia: The Rise of Surveillance Capitalism and the Death of Privacy”—concluded that:

Our lives and behaviour have been turned into profit for the Big Tech giants—and we meekly click ‘Accept.’ How did we sleepwalk into a world without privacy?

In our article, we argue that these fears are symptomatic of two different but complementary phenomena, which we refer to as “Antitrust Dystopia” and “Antitrust Nostalgia.”

Antitrust Dystopia is the pessimistic tendency among competition scholars and enforcers to assert that novel business conduct will cause technological advances to have unprecedented, anticompetitive consequences. This is almost always grounded in the belief that “this time is different”—that, despite the benign or positive consequences of previous, similar technological advances, this time those advances will have dire, adverse consequences absent enforcement to stave off abuse.

Antitrust Nostalgia is the biased assumption—often built into antitrust doctrine itself—that change is bad. Antitrust Nostalgia holds that, because a business practice has seemingly benefited competition before, changing it will harm competition going forward. Thus, antitrust enforcement is often skeptical of, and triggered by, various deviations from status quo conduct and relationships (i.e., “nonstandard” business arrangements) when change is, to a first approximation, the hallmark of competition itself.

Our article argues that these two worldviews are premised on particularly questionable assumptions about the way competition unfolds, in this case, in data-intensive markets.

The Case of Big Data Competition

The notion that digital markets are inherently more problematic than their brick-and-mortar counterparts—if there even is a meaningful distinction—is advanced routinely by policymakers, journalists, and other observers. The fear is that, left to their own devices, today’s dominant digital platforms will become all-powerful, protected by an impregnable “data barrier to entry.” Against this alarmist backdrop, nostalgic antitrust scholars have argued for aggressive antitrust intervention against the nonstandard business models and contractual arrangements that characterize these markets.

But as our paper demonstrates, a proper assessment of the attributes of data-intensive digital markets does not support either the dire claims or the proposed interventions.

  1. Data is information

One of the most salient features of the data created and consumed by online firms is that, jargon aside, it is just information. As with other types of information, it thus tends to have at least some traits usually associated with public goods (i.e., goods that are non-rivalrous in consumption and not readily excludable). As the National Bureau of Economic Research’s Catherine Tucker argues, data “has near-zero marginal cost of production and distribution even over long distances,” making it very difficult to exclude others from accessing it. Meanwhile, multiple economic agents can simultaneously use the same data, making it non-rivalrous in consumption.

As we explain in our paper, these features make the nature of modern data almost irreconcilable with the alleged hoarding and dominance that critics routinely associate with the tech industry.

2. Data is not scarce; expertise is

Another important feature of data is that it is ubiquitous. The predominant challenge for firms is not so much in obtaining data but, rather, in drawing useful insights from it. This has two important implications for antitrust policy.

First, although data does not have the self-reinforcing characteristics of network effects, there is a sense that acquiring a certain amount of data and expertise is necessary to compete in data-heavy industries. It is (or should be) equally apparent, however, that this “learning by doing” advantage rapidly reaches a point of diminishing returns.

This is supported by significant empirical evidence. As our survey of the empirical literature shows, data generally entails diminishing marginal returns:

Second, it is firms’ capabilities, rather than the data they own, that lead to success in the marketplace. Critics who argue that firms such as Amazon, Google, and Facebook are successful because of their superior access to data might, in fact, have the causality in reverse. Arguably, it is because these firms have come up with successful industry-defining paradigms that they have amassed so much data, and not the other way around.

This dynamic can be seen at play in the early days of the search-engine market. In 2013, The Atlantic ran a piece titled “What the Web Looked Like Before Google.” By comparing the websites of Google and its rivals in 1998 (when Google Search was launched), the article shows how the current champion of search marked a radical departure from the status quo.

Even if it stumbled upon it by chance, Google immediately identified a winning formula for the search-engine market. It ditched the complicated classification schemes favored by its rivals and opted, instead, for a clean page with a single search box. This ensured that users could access the information they desired in the shortest possible amount of time—thanks, in part, to Google’s PageRank algorithm.

It is hardly surprising that Google’s rivals struggled to keep up with this shift in the search-engine industry. The theory of dynamic capabilities tells us that firms that have achieved success by indexing the web will struggle when the market rapidly moves toward a new paradigm (in this case, Google’s single search box and ten blue links). During the time it took these rivals to identify their weaknesses and repurpose their assets, Google kept on making successful decisions: notably, the introduction of Gmail, its acquisitions of YouTube and Android, and the introduction of Google Maps, among others.

Seen from this evolutionary perspective, Google thrived because its capabilities were perfect for the market at that time, while rivals were ill-adapted.

3.    Data as a byproduct of, and path to, platform monetization

Policymakers should also bear in mind that platforms often must go to great lengths in order to create data about their users—data that these same users often do not know about themselves. Under this framing, data is a byproduct of firms’ activity, rather than an input necessary for rivals to launch a business.

This is especially clear when one looks at the formative years of numerous online platforms. Most of the time, these businesses were started by entrepreneurs who did not own much data but, instead, had a brilliant idea for a service that consumers would value. Even if data ultimately played a role in the monetization of these platforms, it does not appear that it was necessary for their creation.

Data often becomes significant only at a relatively late stage in these businesses’ development. A quick glance at the digital economy is particularly revealing in this regard. Google and Facebook, in particular, both launched their platforms under the assumption that building a successful product would eventually lead to significant revenues.

It took five years from its launch for Facebook to start making a profit. Even at that point, when the platform had 300 million users, it still was not entirely clear whether it would generate most of its income from app sales or online advertisements. It was another three years before Facebook started to cement its position as one of the world’s leading providers of online ads. During this eight-year timespan, Facebook prioritized user growth over the monetization of its platform. The company appears to have concluded (correctly, it turns out) that once its platform attracted enough users, it would surely find a way to make itself highly profitable.

This might explain how Facebook managed to build a highly successful platform despite a large data disadvantage when compared to rivals like MySpace. And Facebook is no outlier. The list of companies that prevailed despite starting with little to no data (and initially lacking a data-dependent monetization strategy) is lengthy. Other examples include TikTok, Airbnb, Amazon, Twitter, PayPal, Snapchat, and Uber.

Those who complain about the unassailable competitive advantages enjoyed by companies with troves of data have it exactly backward. Companies need to innovate to attract consumer data or else consumers will switch to competitors, including both new entrants and established incumbents. As a result, the desire to make use of more and better data drives competitive innovation, with manifestly impressive results. The continued explosion of new products, services, and apps is evidence that data is not a bottleneck to competition, but a spur to drive it.

We’ve Been Here Before: The Microsoft Antitrust Saga

Dystopian and nostalgic discussions concerning the power of successful technology firms are nothing new. Throughout recent history, there have been repeated calls for antitrust authorities to reign in these large companies. These calls for regulation have often led to increased antitrust scrutiny of some form. The Microsoft antitrust cases—which ran from the 1990s to the early 2010s on both sides of the Atlantic—offer a good illustration of the misguided “Antitrust Dystopia.”

In the mid-1990s, Microsoft was one of the most successful and vilified companies in America. After it obtained a commanding position in the desktop operating system market, the company sought to establish a foothold in the burgeoning markets that were developing around the Windows platform (many of which were driven by the emergence of the Internet). These included the Internet browser and media-player markets.

The business tactics employed by Microsoft to execute this transition quickly drew the ire of the press and rival firms, ultimately landing Microsoft in hot water with antitrust authorities on both sides of the Atlantic.

However, as we show in our article, though there were numerous calls for authorities to adopt a precautionary principle-type approach to dealing with Microsoft—and antitrust enforcers were more than receptive to these calls—critics’ worst fears never came to be.

This positive outcome is unlikely to be the result of the antitrust cases that were brought against Microsoft. In other words, the markets in which Microsoft operated seem to have self-corrected (or were misapprehended as competitively constrained) and, today, are generally seen as being unproblematic.

This is not to say that antitrust interventions against Microsoft were necessarily misguided. Instead, our critical point is that commentators and antitrust decisionmakers routinely overlooked or misinterpreted the existing and nonstandard market dynamics that ultimately prevented the worst anticompetitive outcomes from materializing. This is supported by several key factors.

First, the remedies that were imposed against Microsoft by antitrust authorities on both sides of the Atlantic were ultimately quite weak. It is thus unlikely that these remedies, by themselves, prevented Microsoft from dominating its competitors in adjacent markets.

Note that, if this assertion is wrong, and antitrust enforcement did indeed prevent Microsoft from dominating online markets, then there is arguably no need to reform the antitrust laws on either side of the Atlantic, nor even to adopt a particularly aggressive enforcement position. The remedies that were imposed on Microsoft were relatively localized. Accordingly, if antitrust enforcement did indeed prevent Microsoft from dominating other online markets, then it is antitrust enforcement’s deterrent effect that is to thank, and not the remedies actually imposed.

Second, Microsoft lost its bottleneck position. One of the biggest changes that took place in the digital space was the emergence of alternative platforms through which consumers could access the Internet. Indeed, as recently as January 2009, roughly 94% of all Internet traffic came from Windows-based computers. Just over a decade later, this number has fallen to about 31%. Android, iOS, and OS X have shares of roughly 41%, 16%, and 7%, respectively. Consumers can thus access the web via numerous platforms. The emergence of these alternatives reduced the extent to which Microsoft could use its bottleneck position to force its services on consumers in online markets.

Third, it is possible that Microsoft’s own behavior ultimately sowed the seeds of its relative demise. In particular, the alleged barriers to entry (rooted in nostalgic market definitions and skeptical analysis of “ununderstandable” conduct) that were essential to establishing the antitrust case against the company may have been pathways to entry as much as barriers.

Consider this error in the Microsoft court’s analysis of entry barriers: the court pointed out that new entrants faced a barrier that Microsoft didn’t face, in that Microsoft didn’t have to contend with a powerful incumbent impeding its entry by tying up application developers.

But while this may be true, Microsoft did face the absence of any developers at all, and had to essentially create (or encourage the creation of) businesses that didn’t previously exist. Microsoft thus created a huge positive externality for new entrants: existing knowledge and organizations devoted to software development, industry knowledge, reputation, awareness, and incentives for schools to offer courses. It could well be that new entrants, in fact, faced lower barriers with respect to app developers than did Microsoft when it entered.

In short, new entrants may face even more welcoming environments because of incumbents. This enabled Microsoft’s rivals to thrive.

Conclusion

Dystopian antitrust prophecies are generally doomed to fail, just like those belonging to the literary world. The reason is simple. While it is easy to identify what makes dominant firms successful in the present (i.e., what enables them to hold off competitors in the short term), it is almost impossible to conceive of the myriad ways in which the market could adapt. Indeed, it is today’s supra-competitive profits that spur the efforts of competitors.

Surmising that the economy will come to be dominated by a small number of successful firms is thus the same as believing that all market participants can be outsmarted by a few successful ones. This might occur in some cases or for some period of time, but as our article argues, it is bound to happen far less often than pessimists fear.

In short, dystopian scholars have not successfully made the case for precautionary antitrust. Indeed, the economic features of data make it highly unlikely that today’s tech giants could anticompetitively maintain their advantage for an indefinite amount of time, much less leverage this advantage in adjacent markets.

With this in mind, there is one dystopian novel that offers a fitting metaphor to end this Article. The Man in the High Castle tells the story of an alternate present, where Axis forces triumphed over the Allies during the second World War. This turns the dystopia genre on its head: rather than argue that the world is inevitably sliding towards a dark future, The Man in the High Castle posits that the present could be far worse than it is.

In other words, we should not take any of the luxuries we currently enjoy for granted. In the world of antitrust, critics routinely overlook that the emergence of today’s tech industry might have occurred thanks to, and not in spite of, existing antitrust doctrine. Changes to existing antitrust law should thus be dictated by a rigorous assessment of the various costs and benefits they would entail, rather than a litany of hypothetical concerns. The most recent wave of calls for antitrust reform have so far failed to clear this low bar.

The American Choice and Innovation Online Act (previously called the Platform Anti-Monopoly Act), introduced earlier this summer by U.S. Rep. David Cicilline (D-R.I.), would significantly change the nature of digital platforms and, with them, the internet itself. Taken together, the bill’s provisions would turn platforms into passive intermediaries, undermining many of the features that make them valuable to consumers. This seems likely to remain the case even after potential revisions intended to minimize the bill’s unintended consequences.

In its current form, the bill is split into two parts that each is dangerous in its own right. The first, Section 2(a), would prohibit almost any kind of “discrimination” by platforms. Because it is so open-ended, lawmakers might end up removing it in favor of the nominally more focused provisions of Section 2(b), which prohibit certain named conduct. But despite being more specific, this section of the bill is incredibly far-reaching and would effectively ban swaths of essential services.

I will address the potential effects of these sections point-by-point, but both elements of the bill suffer from the same problem: a misguided assumption that “discrimination” by platforms is necessarily bad from a competition and consumer welfare point of view. On the contrary, this conduct is often exactly what consumers want from platforms, since it helps to bring order and legibility to otherwise-unwieldy parts of the Internet. Prohibiting it, as both main parts of the bill do, would make the Internet harder to use and less competitive.

Section 2(a)

Section 2(a) essentially prohibits any behavior by a covered platform that would advantage that platform’s services over any others that also uses that platform; it characterizes this preferencing as “discrimination.”

As we wrote when the House Judiciary Committee’s antitrust bills were first announced, this prohibition on “discrimination” is so broad that, if it made it into law, it would prevent platforms from excluding or disadvantaging any product of another business that uses the platform or advantaging their own products over those of their competitors.

The underlying assumption here is that platforms should be like telephone networks: providing a way for different sides of a market to communicate with each other, but doing little more than that. When platforms do do more—for example, manipulating search results to favor certain businesses or to give their own products prominence —it is seen as exploitative “leveraging.”

But consumers often want platforms to be more than just a telephone network or directory, because digital markets would be very difficult to navigate without some degree of “discrimination” between sellers. The Internet is so vast and sellers are often so anonymous that any assistance which helps you choose among options can serve to make it more navigable. As John Gruber put it:

From what I’ve seen over the last few decades, the quality of the user experience of every computing platform is directly correlated to the amount of control exerted by its platform owner. The current state of the ownerless world wide web speaks for itself.

Sometimes, this manifests itself as “self-preferencing” of another service, to reduce additional time spent searching for the information you want. When you search for a restaurant on Google, it can be very useful to get information like user reviews, the restaurant’s phone number, a button on mobile to phone them directly, estimates of how busy it is, and a link to a Maps page to see how to actually get there.

This is, undoubtedly, frustrating for competitors like Yelp, who would like this information not to be there and for users to have to click on either a link to Yelp or a link to Google Maps. But whether it is good or bad for Yelp isn’t relevant to whether it is good for users—and it is at least arguable that it is, which makes a blanket prohibition on this kind of behavior almost inevitably harmful.

If it isn’t obvious why removing this kind of feature would be harmful for users, ask yourself why some users search in Yelp’s app directly for this kind of result. The answer, I think, is that Yelp gives you all the information above that Google does (and sometimes is better, although I tend to trust Google Maps’ reviews over Yelp’s), and it’s really convenient to have all that on the same page. If Google could not provide this kind of “rich” result, many users would probably stop using Google Search to look for restaurant information in the first place, because a new friction would have been added that made the experience meaningfully worse. Removing that option would be good for Yelp, but mainly because it removes a competitor.

If all this feels like stating the obvious, then it should highlight a significant problem with Section 2(a) in the Cicilline bill: it prohibits conduct that is directly value-adding for consumers, and that creates competition for dedicated services like Yelp that object to having to compete with this kind of conduct.

This is true across all the platforms the legislation proposes to regulate. Amazon prioritizes some third-party products over others on the basis of user reviews, rates of returns and complaints, and so on; Amazon provides private label products to fill gaps in certain product lines where existing offerings are expensive or unreliable; Apple pre-installs a Camera app on the iPhone that, obviously, enjoys an advantage over rival apps like Halide.

Some or all of this behavior would be prohibited under Section 2(a) of the Cicilline bill. Combined with the bill’s presumption that conduct must be defended affirmatively—that is, the platform is presumed guilty unless it can prove that the challenged conduct is pro-competitive, which may be very difficult to do—and the bill could prospectively eliminate a huge range of socially valuable behavior.

Supporters of the bill have already been left arguing that the law simply wouldn’t be enforced in these cases of benign discrimination. But this would hardly be an improvement. It would mean the Federal Trade Commission (FTC) and U.S. Justice Department (DOJ) have tremendous control over how these platforms are built, since they could challenge conduct in virtually any case. The regulatory uncertainty alone would complicate the calculus for these firms as they refine, develop, and deploy new products and capabilities. 

So one potential compromise might be to do away with this broad-based rule and proscribe specific kinds of “discriminatory” conduct instead. This approach would involve removing Section 2(a) from the bill but retaining Section 2(b), which enumerates 10 practices it deems to be “other discriminatory conduct.” This may seem appealing, as it would potentially avoid the worst abuses of the broad-based prohibition. In practice, however, it would carry many of the same problems. In fact, many of 2(b)’s provisions appear to go even further than 2(a), and would proscribe even more procompetitive conduct that consumers want.

Sections 2(b)(1) and 2(b)(9)

The wording of these provisions is extremely broad and, as drafted, would seem to challenge even the existence of vertically integrated products. As such, these prohibitions are potentially even more extensive and invasive than Section 2(a) would have been. Even a narrower reading here would seem to preclude safety and privacy features that are valuable to many users. iOS’s sandboxing of apps, for example, serves to limit the damage that a malware app can do on a user’s device precisely because of the limitations it imposes on what other features and hardware the app can access.

Section 2(b)(2)

This provision would preclude a firm from conditioning preferred status on use of another service from that firm. This would likely undermine the purpose of platforms, which is to absorb and counter some of the risks involved in doing business online. An example of this is Amazon’s tying eligibility for its Prime program to sellers that use Amazon’s delivery service (FBA – Fulfilled By Amazon). The bill seems to presume in an example like this that Amazon is leveraging its power in the market—in the form of the value of the Prime label—to profit from delivery. But Amazon could, and already does, charge directly for listing positions; it’s unclear why it would benefit from charging via FBA when it could just charge for the Prime label.

An alternate, simpler explanation is that FBA improves the quality of the service, by granting customers greater assurance that a Prime product will arrive when Amazon says it will. Platforms add value by setting out rules and providing services that reduce the uncertainties between buyers and sellers they’d otherwise experience if they transacted directly with each other. This section’s prohibition—which, as written, would seem to prevent any kind of quality assurance—likely would bar labelling by a platform, even where customers explicitly want it.

Section 2(b)(3)

As written, this would prohibit platforms from using aggregated data to improve their services at all. If Apple found that 99% of its users uninstalled an app immediately after it was installed, it would be reasonable to conclude that the app may be harmful or broken in some way, and that Apple should investigate. This provision would ban that.

Sections 2(b)(4) and 2(b)(6)

These two provisions effectively prohibit a platform from using information it does not also provide to sellers. Such prohibitions ignore the fact that it is often good for sellers to lack certain information, since withholding information can prevent abuse by malicious users. For example, a seller may sometimes try to bribe their customers to post positive reviews of their products, or even threaten customers who have posted negative ones. Part of the role of a platform is to combat that kind of behavior by acting as a middleman and forcing both consumer users and business users to comply with the platform’s own mechanisms to control that kind of behavior.

If this seems overly generous to platforms—since, obviously, it gives them a lot of leverage over business users—ask yourself why people use platforms at all. It is not a coincidence that people often prefer Amazon to dealing with third-party merchants and having to navigate those merchants’ sites themselves. The assurance that Amazon provides is extremely valuable for users. Much of it comes from the company’s ability to act as a middleman in this way, lowering the transaction costs between buyers and sellers.

Section 2(b)(5)

This provision restricts the treatment of defaults. It is, however, relatively restrained when compared to, for example, the DOJ’s lawsuit against Google, which treats as anticompetitive even payment for defaults that can be changed. Still, many of the arguments that apply in that case also apply here: default status for apps can be a way to recoup income foregone elsewhere (e.g., a browser provided for free that makes its money by selling the right to be the default search engine).

Section 2(b)(7)

This section gets to the heart of why “discrimination” can often be procompetitive: that it facilitates competition between platforms. The kind of self-preferencing that this provision would prohibit can allow firms that have a presence in one market to extend that position into another, increasing competition in the process. Both Apple and Amazon have used their customer bases in smartphones and e-commerce, respectively, to grow their customer bases for video streaming, in competition with Netflix, Google’s YouTube, cable television, and each other. If Apple designed a search engine to compete with Google, it would do exactly the same thing, and we would be better off because of it. Restricting this kind of behavior is, perversely, exactly what you would do if you wanted to shield these incumbents from competition.

Section 2(b)(8)

As with other provisions, this one would preclude one of the mechanisms by which platforms add value: creating assurance for customers about the products they can expect if they visit the platform. Some of this relates to child protection; some of the most frustrating stories involve children being overcharged when they use an iPhone or Android app, and effectively being ripped off because of poor policing of the app (or insufficiently strict pricing rules by Apple or Google). This may also relate to rules that state that the seller cannot offer a cheaper product elsewhere (Amazon’s “General Pricing Rule” does this, for example). Prohibiting this would simply impose a tax on customers who cannot shop around and would prefer to use a platform that they trust has the lowest prices for the item they want.

Section 2(b)(10)

Ostensibly a “whistleblower” provision, this section could leave platforms with no recourse, not even removing a user from its platform, in response to spurious complaints intended purely to extract value for the complaining business rather than to promote competition. On its own, this sort of provision may be fairly harmless, but combined with the provisions above, it allows the bill to add up to a rent-seekers’ charter.

Conclusion

In each case above, it’s vital to remember that a reversed burden of proof applies. So, there is a high chance that the law will side against the defendant business, and a large downside for conduct that ends up being found to violate these provisions. That means that platforms will likely err on the side of caution in many cases, avoiding conduct that is ambiguous, and society will probably lose a lot of beneficial behavior in the process.

Put together, the provisions undermine much of what has become an Internet platform’s role: to act as an intermediary, de-risk transactions between customers and merchants who don’t know each other, and tweak the rules of the market to maximize its attractiveness as a place to do business. The “discrimination” that the bill would outlaw is, in practice, behavior that makes it easier for consumers to navigate marketplaces of extreme complexity and uncertainty, in which they often know little or nothing about the firms with whom they are trying to transact business.

Customers do not want platforms to be neutral, open utilities. They can choose platforms that are like that already, such as eBay. They generally tend to prefer ones like Amazon, which are not neutral and which carefully cultivate their service to be as streamlined, managed, and “discriminatory” as possible. Indeed, many of people’s biggest complaints with digital platforms relate to their openness: the fake reviews, counterfeit products, malware, and spam that come with letting more unknown businesses use your service. While these may be unavoidable by-products of running a platform, platforms compete on their ability to ferret them out. Customers are unlikely to thank legislators for regulating Amazon into being another eBay.

The language of the federal antitrust laws is extremely general. Over more than a century, the federal courts have applied common-law techniques to construe this general language to provide guidance to the private sector as to what does or does not run afoul of the law. The interpretive process has been fraught with some uncertainty, as judicial approaches to antitrust analysis have changed several times over the past century. Nevertheless, until very recently, judges and enforcers had converged toward relying on a consumer welfare standard as the touchstone for antitrust evaluations (see my antitrust primer here, for an overview).

While imperfect and subject to potential error in application—a problem of legal interpretation generally—the consumer welfare principle has worked rather well as the focus both for antitrust-enforcement guidance and judicial decision-making. The general stability and predictability of antitrust under a consumer welfare framework has advanced the rule of law. It has given businesses sufficient information to plan transactions in a manner likely to avoid antitrust liability. It thereby has cabined uncertainty and increased the probability that private parties would enter welfare-enhancing commercial arrangements, to the benefit of society.

In a very thoughtful 2017 speech, then Acting Assistant Attorney General for Antitrust Andrew Finch commented on the importance of the rule of law to principled antitrust enforcement. He noted:

[H]ow do we administer the antitrust laws more rationally, accurately, expeditiously, and efficiently? … Law enforcement requires stability and continuity both in rules and in their application to specific cases.

Indeed, stability and continuity in enforcement are fundamental to the rule of law. The rule of law is about notice and reliance. When it is impossible to make reasonable predictions about how a law will be applied, or what the legal consequences of conduct will be, these important values are diminished. To call our antitrust regime a “rule of law” regime, we must enforce the law as written and as interpreted by the courts and advance change with careful thought.

The reliance fostered by stability and continuity has obvious economic benefits. Businesses invest, not only in innovation but in facilities, marketing, and personnel, and they do so based on the economic and legal environment they expect to face.

Of course, we want businesses to make those investments—and shape their overall conduct—in accordance with the antitrust laws. But to do so, they need to be able to rely on future application of those laws being largely consistent with their expectations. An antitrust enforcement regime with frequent changes is one that businesses cannot plan for, or one that they will plan for by avoiding certain kinds of investments.

That is certainly not to say there has not been positive change in the antitrust laws in the past, or that we would have been better off without those changes. U.S. antitrust law has been refined, and occasionally recalibrated, with the courts playing their appropriate interpretive role. And enforcers must always be on the watch for new or evolving threats to competition.  As markets evolve and products develop over time, our analysis adapts. But as those changes occur, we pursue reliability and consistency in application in the antitrust laws as much as possible.

Indeed, we have enjoyed remarkable continuity and consensus for many years. Antitrust law in the U.S. has not been a “paradox” for quite some time, but rather a stable and valuable law enforcement regime with appropriately widespread support.

Unfortunately, policy decisions taken by the new Federal Trade Commission (FTC) leadership in recent weeks have rejected antitrust continuity and consensus. They have injected substantial uncertainty into the application of competition-law enforcement by the FTC. This abrupt change in emphasis undermines the rule of law and threatens to reduce economic welfare.

As of now, the FTC’s departure from the rule of law has been notable in two areas:

  1. Its rejection of previous guidance on the agency’s “unfair methods of competition” authority, the FTC’s primary non-merger-related enforcement tool; and
  2. Its new advice rejecting time limits for the review of generally routine proposed mergers.

In addition, potential FTC rulemakings directed at “unfair methods of competition” would, if pursued, prove highly problematic.

Rescission of the Unfair Methods of Competition Policy Statement

The FTC on July 1 voted 3-2 to rescind the 2015 FTC Policy Statement Regarding Unfair Methods of Competition under Section 5 of the FTC Act (UMC Policy Statement).

The bipartisan UMC Policy Statement has originally been supported by all three Democratic commissioners, including then-Chairwoman Edith Ramirez. The policy statement generally respected and promoted the rule of law by emphasizing that, in applying the facially broad “unfair methods of competition” (UMC) language, the FTC would be guided by the well-established principles of the antitrust rule of reason (including considering any associated cognizable efficiencies and business justifications) and the consumer welfare standard. The FTC also explained that it would not apply “standalone” Section 5 theories to conduct that would violate the Sherman or Clayton Acts.

In short, the UMC Policy Statement sent a strong signal that the commission would apply UMC in a manner fully consistent with accepted and well-understood antitrust policy principles. As in the past, the vast bulk of FTC Section 5 prosecutions would be brought against conduct that violated the core antitrust laws. Standalone Section 5 cases would be directed solely at those few practices that harmed consumer welfare and competition, but somehow fell into a narrow crack in the basic antitrust statutes (such as, perhaps, “invitations to collude” that lack plausible efficiency justifications). Although the UMC Statement did not answer all questions regarding what specific practices would justify standalone UMC challenges, it substantially limited business uncertainty by bringing Section 5 within the boundaries of settled antitrust doctrine.

The FTC’s announcement of the UMC Policy Statement rescission unhelpfully proclaimed that “the time is right for the Commission to rethink its approach and to recommit to its mandate to police unfair methods of competition even if they are outside the ambit of the Sherman or Clayton Acts.” As a dissenting statement by Commissioner Christine S. Wilson warned, consumers would be harmed by the commission’s decision to prioritize other unnamed interests. And as Commissioner Noah Joshua Phillips stressed in his dissent, the end result would be reduced guidance and greater uncertainty.

In sum, by suddenly leaving private parties in the dark as to how to conform themselves to Section 5’s UMC requirements, the FTC’s rescission offends the rule of law.

New Guidance to Parties Considering Mergers

For decades, parties proposing mergers that are subject to statutory Hart-Scott-Rodino (HSR) Act pre-merger notification requirements have operated under the understanding that:

  1. The FTC and U.S. Justice Department (DOJ) will routinely grant “early termination” of review (before the end of the initial 30-day statutory review period) to those transactions posing no plausible competitive threat; and
  2. An enforcement agency’s decision not to request more detailed documents (“second requests”) after an initial 30-day pre-merger review effectively serves as an antitrust “green light” for the proposed acquisition to proceed.

Those understandings, though not statutorily mandated, have significantly reduced antitrust uncertainty and related costs in the planning of routine merger transactions. The rule of law has been advanced through an effective assurance that business combinations that appear presumptively lawful will not be the target of future government legal harassment. This has advanced efficiency in government, as well; it is a cost-beneficial optimal use of resources for DOJ and the FTC to focus exclusively on those proposed mergers that present a substantial potential threat to consumer welfare.

Two recent FTC pronouncements (one in tandem with DOJ), however, have generated great uncertainty by disavowing (at least temporarily) those two welfare-promoting review policies. Joined by DOJ, the FTC on Feb. 4 announced that the agencies would temporarily suspend early terminations, citing an “unprecedented volume of filings” and a transition to new leadership. More than six months later, this “temporary” suspension remains in effect.

Citing “capacity constraints” and a “tidal wave of merger filings,” the FTC subsequently published an Aug. 3 blog post that effectively abrogated the 30-day “green lighting” of mergers not subject to a second request. It announced that it was sending “warning letters” to firms reminding them that FTC investigations remain open after the initial 30-day period, and that “[c]ompanies that choose to proceed with transactions that have not been fully investigated are doing so at their own risk.”

The FTC’s actions interject unwarranted uncertainty into merger planning and undermine the rule of law. Preventing early termination on transactions that have been approved routinely not only imposes additional costs on business; it hints that some transactions might be subject to novel theories of liability that fall outside the antitrust consensus.

Perhaps more significantly, as three prominent antitrust practitioners point out, the FTC’s warning letters states that:

[T]he FTC may challenge deals that “threaten to reduce competition and harm consumers, workers, and honest businesses.” Adding in harm to both “workers and honest businesses” implies that the FTC may be considering more ways that transactions can have an adverse impact other than just harm to competition and consumers [citation omitted].

Because consensus antitrust merger analysis centers on consumer welfare, not the protection of labor or business interests, any suggestion that the FTC may be extending its reach to these new areas is inconsistent with established legal principles and generates new business-planning risks.

More generally, the Aug. 6 FTC “blog post could be viewed as an attempt to modify the temporal framework of the HSR Act”—in effect, an effort to displace an implicit statutory understanding in favor of an agency diktat, contrary to the rule of law. Commissioner Wilson sees the blog post as a means to keep investigations open indefinitely and, thus, an attack on the decades-old HSR framework for handling most merger reviews in an expeditious fashion (see here). Commissioner Phillips is concerned about an attempt to chill legal M&A transactions across the board, particularly unfortunate when there is no reason to conclude that particular transactions are illegal (see here).

Finally, the historical record raises serious questions about the “resource constraint” justification for the FTC’s new merger review policies:

Through the end of July 2021, more than 2,900 transactions were reported to the FTC. It is not clear, however, whether these record-breaking HSR filing numbers have led (or will lead) to more deals being investigated. Historically, only about 13 percent of all deals reported are investigated in some fashion, and roughly 3 percent of all deals reported receive a more thorough, substantive review through the issuance of a Second Request. Even if more deals are being reported, for the majority of transactions, the HSR process is purely administrative, raising no antitrust concerns, and, theoretically, uses few, if any, agency resources. [Citations omitted.]

Proposed FTC Competition Rulemakings

The new FTC leadership is strongly considering competition rulemakings. As I explained in a recent Truth on the Market post, such rulemakings would fail a cost-benefit test. They raise serious legal risks for the commission and could impose wasted resource costs on the FTC and on private parties. More significantly, they would raise two very serious economic policy concerns:

First, competition rules would generate higher error costs than adjudications. Adjudications cabin error costs by allowing for case-specific analysis of likely competitive harms and procompetitive benefits. In contrast, competition rules inherently would be overbroad and would suffer from a very high rate of false positives. By characterizing certain practices as inherently anticompetitive without allowing for consideration of case-specific facts bearing on actual competitive effects, findings of rule violations inevitably would condemn some (perhaps many) efficient arrangements.

Second, competition rules would undermine the rule of law and thereby reduce economic welfare. FTC-only competition rules could lead to disparate legal treatment of a firm’s business practices, depending upon whether the FTC or the U.S. Justice Department was the investigating agency. Also, economic efficiency gains could be lost due to the chilling of aggressive efficiency-seeking business arrangements in those sectors subject to rules. [Emphasis added.]

In short, common law antitrust adjudication, focused on the consumer welfare standard, has done a good job of promoting a vibrant competitive economy in an efficient fashion. FTC competition rulemaking would not.

Conclusion

Recent FTC actions have undermined consensus antitrust-enforcement standards and have departed from established merger-review procedures with respect to seemingly uncontroversial consolidations. Those decisions have imposed costly uncertainty on the business sector and are thereby likely to disincentivize efficiency-seeking arrangements. What’s more, by implicitly rejecting consensus antitrust principles, they denigrate the primacy of the rule of law in antitrust enforcement. The FTC’s pursuit of competition rulemaking would further damage the rule of law by imposing arbitrary strictures that ignore matter-specific considerations bearing on the justifications for particular business decisions.

Fortunately, these are early days in the Biden administration. The problematic initial policy decisions delineated in this comment could be reversed based on further reflection and deliberation within the commission. Chairwoman Lina Khan and her fellow Democratic commissioners would benefit by consulting more closely with Commissioners Wilson and Phillips to reach agreement on substantive and procedural enforcement policies that are better tailored to promote consumer welfare and enhance vibrant competition. Such policies would benefit the U.S. economy in a manner consistent with the rule of law.

In a recent op-ed, Robert Bork Jr. laments the Biden administration’s drive to jettison the Consumer Welfare Standard that has formed nearly half a century of antitrust jurisprudence. The move can be seen in the near-revolution at the Federal Trade Commission, in the president’s executive order on competition enforcement, and in several of the major antitrust bills currently before Congress.

Bork notes the Competition and Antitrust Law Enforcement Reform Act, introduced by Sen. Amy Klobuchar (D-Minn.), would “outlaw any mergers or acquisitions for the more than 80 large U.S. companies valued over $100 billion.”

Bork is correct that it will be more than 80 companies, but it is likely to be way more. While the Klobuchar bill does not explicitly outlaw such mergers, under certain circumstances, it shifts the burden of proof to the merging parties, who must demonstrate that the benefits of the transaction outweigh the potential risks. Under current law, the burden is on the government to demonstrate the potential costs outweigh the potential benefits.

One of the measure’s specific triggers for this burden-shifting is if the acquiring party has a market capitalization, assets, or annual net revenue of more than $100 billion and seeks a merger or acquisition valued at $50 million or more. About 120 or more U.S. companies satisfy at least one of these conditions. The end of this post provides a list of publicly traded companies, according to Zacks’ stock screener, that would likely be subject to the shift in burden of proof.

If the goal is to go after Big Tech, the Klobuchar bill hits the mark. All of the FAANG companies—Facebook, Amazon, Apple, Netflix, and Alphabet (formerly known as Google)—satisfy one or more of the criteria. So do Microsoft and PayPal.

But even some smaller tech firms will be subject to the shift in burden of proof. Zoom and Square have market caps that would trigger under Klobuchar’s bill and Snap is hovering around $100 billion in market cap. Twitter and eBay, however, are well under any of the thresholds. Likewise, privately owned Advance Communications, owner of Reddit, would also likely fall short of any of the triggers.

Snapchat has a little more than 300 million monthly active users. Twitter and Reddit each have about 330 million monthly active users. Nevertheless, under the Klobuchar bill, Snapchat is presumed to have more market power than either Twitter or Reddit, simply because the market assigns a higher valuation to Snap.

But this bill is about more than Big Tech. Tesla, which sold its first car only 13 years ago, is now considered big enough that it will face the same antitrust scrutiny as the Big 3 automakers. Walmart, Costco, and Kroger would be subject to the shifted burden of proof, while Safeway and Publix would escape such scrutiny. An acquisition by U.S.-based Nike would be put under the microscope, but a similar acquisition by Germany’s Adidas would not fall under the Klobuchar bill’s thresholds.

Tesla accounts for less than 2% of the vehicles sold in the United States. I have no idea what Walmart, Costco, Kroger, or Nike’s market share is, or even what comprises “the” market these companies compete in. What we do know is that the U.S. Department of Justice and Federal Trade Commission excel at narrowly crafting market definitions so that just about any company can be defined as dominant.

So much of the recent interest in antitrust has focused on Big Tech. But even the biggest of Big Tech firms operate in dynamic and competitive markets. None of my four children use Facebook or Twitter. My wife and I don’t use Snapchat. We all use Netflix, but we also use Hulu, Disney+, HBO Max, YouTube, and Amazon Prime Video. None of these services have a monopoly on our eyeballs, our attention, or our pocketbooks.

The antitrust bills currently working their way through Congress abandon the long-standing balancing of pro- versus anti-competitive effects of mergers in favor of a “big is bad” approach. While the Klobuchar bill appears to provide clear guidance on the thresholds triggering a shift in the burden of proof, the arbitrary nature of the thresholds will result in arbitrary application of the burden of proof. If passed, we will soon be faced with a case in which two firms who differ only in market cap, assets, or sales will be subject to very different antitrust scrutiny, resulting in regulatory chaos.

A lot of water has gone under the bridge since my book was published last year. To close this symposium, I thought I would discuss the new phase of antirust statutorification taking place before our eyes. In the United States, Congress is working on five antitrust bills that propose to subject platforms to stringent obligations, including a ban on mergers and acquisitions, required data portability and interoperability, and line-of-business restrictions. In the European Union (EU), lawmakers are examining the proposed Digital Markets Act (“DMA”) that sets out a complicated regulatory system for digital “gatekeepers,” with per se behavioral limitations of their freedom over contractual terms, technological design, monetization, and ecosystem leadership.

Proponents of legislative reform on both sides of the Atlantic appear to share the common view that ongoing antitrust adjudication efforts are both instrumental and irrelevant. They are instrumental because government (or plaintiff) losses build the evidence needed to support the view that antitrust doctrine is exceedingly conservative, and that legal reform is needed. Two weeks ago, antitrust reform activists ran to Twitter to point out that the U.S. District Court dismissal of the Federal Trade Commission’s (FTC) complaint against Facebook was one more piece of evidence supporting the view that the antitrust pendulum needed to swing. They are instrumental because, again, government (or plaintiffs) wins will support scaling antitrust enforcement in the marginal case by adoption of governmental regulation. In the EU, antitrust cases follow each other almost like night the day, lending credence to the view that regulation will bring much needed coordination and economies of scale.

But both instrumentalities are, at the end of the line, irrelevant, because they lead to the same conclusion: legislative reform is long overdue. With this in mind, the logic of lawmakers is that they need not await the courts, and they can advance with haste and confidence toward the promulgation of new antitrust statutes.

The antitrust reform process that is unfolding is a cause for questioning. The issue is not legal reform in itself. There is no suggestion here that statutory reform is necessarily inferior, and no correlative reification of the judge-made-law method. Legislative intervention can occur for good reason, like when it breaks judicial inertia caused by ideological logjam.

The issue is rather one of precipitation. There is a lot of learning in the cases. The point, simply put, is that a supplementary court-legislative dialogue would yield additional information—or what Guido Calabresi has called “starting points” for regulation—that premature legislative intervention is sweeping under the rug. This issue is important because specification errors (see Doug Melamed’s symposium piece on this) in statutory legislation are not uncommon. Feedback from court cases create a factual record that will often be missing when lawmakers act too precipitously.

Moreover, a court-legislative iteration is useful when the issues in discussion are cross-cutting. The digital economy brings an abundance of them. As tech analysist Ben Evans has observed, data-sharing obligations raise tradeoffs between contestability and privacy. Chapter VI of my book shows that breakups of social networks or search engines might promote rivalry and, at the same time, increase the leverage of advertisers to extract more user data and conduct more targeted advertising. In such cases, Calabresi said, judges who know the legal topography are well-placed to elicit the preferences of society. He added that they are better placed than government agencies’ officials or delegated experts, who often attend to the immediate problem without the big picture in mind (all the more when officials are denied opportunities to engage with civil society and the press, as per the policy announced by the new FTC leadership).

Of course, there are three objections to this. The first consists of arguing that statutes are needed now because courts are too slow to deal with problems. The argument is not dissimilar to Frank Easterbrook’s concerns about irreversible harms to the economy, though with a tweak. Where Easterbook’s concern was one of ossification of Type I errors due to stare decisis, the concern here is one of entrenchment of durable monopoly power in the digital sector due to Type II errors. The concern, however, fails the test of evidence. The available data in both the United States and Europe shows unprecedented vitality in the digital sector. Venture capital funding cruises at historical heights, fueling new firm entry, business creation, and economic dynamism in the U.S. and EU digital sectors, topping all other industries. Unless we require higher levels of entry from digital markets than from other industries—or discount the social value of entry in the digital sector—this should give us reason to push pause on lawmaking efforts.

The second objection is that following an incremental process of updating the law through the courts creates intolerable uncertainty. But this objection, too, is unconvincing, at best. One may ask which of an abrupt legislative change of the law after decades of legal stability or of an experimental process of judicial renovation brings more uncertainty.

Besides, ad hoc statutes, such as the ones in discussion, are likely to pose quickly and dramatically the problem of their own legal obsolescence. Detailed and technical statutes specify rights, requirements, and procedures that often do not stand the test of time. For example, the DMA likely captures Windows as a core platform service subject to gatekeeping. But is the market power of Microsoft over Windows still relevant today, and isn’t it constrained in effect by existing antitrust rules?  In antitrust, vagueness in critical statutory terms allows room for change.[1] The best way to give meaning to buzzwords like “smart” or “future-proof” regulation consists of building in first principles, not in creating discretionary opportunities for permanent adaptation of the law. In reality, it is hard to see how the methods of future-proof regulation currently discussed in the EU creates less uncertainty than a court process.

The third objection is that we do not need more information, because we now benefit from economic knowledge showing that existing antitrust laws are too permissive of anticompetitive business conduct. But is the economic literature actually supportive of stricter rules against defendants than the rule-of-reason framework that applies in many unilateral conduct cases and in merger law? The answer is surely no. The theoretical economic literature has travelled a lot in the past 50 years. Of particular interest are works on network externalities, switching costs, and multi-sided markets. But the progress achieved in the economic understanding of markets is more descriptive than normative.

Take the celebrated multi-sided market theory. The main contribution of the theory is its advice to decision-makers to take the periscope out, so as to consider all possible welfare tradeoffs, not to be more or less defendant friendly. Payment cards provide a good example. Economic research suggests that any antitrust or regulatory intervention on prices affect tradeoffs between, and payoffs to, cardholders and merchants, cardholders and cash users, cardholders and banks, and banks and card systems. Equally numerous tradeoffs arise in many sectors of the digital economy, like ridesharing, targeted advertisement, or social networks. Multi-sided market theory renders these tradeoffs visible. But it does not come with a clear recipe for how to solve them. For that, one needs to follow first principles. A system of measurement that is flexible and welfare-based helps, as Kelly Fayne observed in her critical symposium piece on the book.

Another example might be worth considering. The theory of increasing returns suggests that markets subject to network effects tend to converge around the selection of a single technology standard, and it is not a given that the selected technology is the best one. One policy implication is that social planners might be justified in keeping a second option on the table. As I discuss in Chapter V of my book, the theory may support an M&A ban against platforms in tipped markets, on the conjecture that the assets of fringe firms might be efficiently repositioned to offer product differentiation to consumers. But the theory of increasing returns does not say under what conditions we can know that the selected technology is suboptimal. Moreover, if the selected technology is the optimal one, or if the suboptimal technology quickly obsolesces, are policy efforts at all needed?

Last, as Bo Heiden’s thought provoking symposium piece argues, it is not a given that antitrust enforcement of rivalry in markets is the best way to maintain an alternative technology alive, let alone to supply the innovation needed to deliver economic prosperity. Government procurement, science and technology policy, and intellectual-property policy might be equally effective (note that the fathers of the theory, like Brian Arthur or Paul David, have been very silent on antitrust reform).

There are, of course, exceptions to the limited normative content of modern economic theory. In some areas, economic theory is more predictive of consumer harms, like in relation to algorithmic collusion, interlocking directorates, or “killer” acquisitions. But the applications are discrete and industry-specific. All are insufficient to declare that the antitrust apparatus is dated and that it requires a full overhaul. When modern economic research turns normative, it is often way more subtle in its implications than some wild policy claims derived from it. For example, the emerging studies that claim to identify broad patterns of rising market power in the economy in no way lead to an implication that there are no pro-competitive mergers.

Similarly, the empirical picture of digital markets is incomplete. The past few years have seen a proliferation of qualitative research reports on industry structure in the digital sectors. Most suggest that industry concentration has risen, particularly in the digital sector. As with any research exercise, these reports’ findings deserve to be subject to critical examination before they can be deemed supportive of a claim of “sufficient experience.” Moreover, there is no reason to subject these reports to a lower standard of accountability on grounds that they have often been drafted by experts upon demand from antitrust agencies. After all, we academics are ethically obliged to be at least equally exacting with policy-based research as we are with science-based research.

Now, with healthy skepticism at the back of one’s mind, one can see immediately that the findings of expert reports to date have tended to downplay behavioral observations that counterbalance findings of monopoly power—such as intense business anxiety, technological innovation, and demand-expansion investments in digital markets. This was, I believe, the main takeaway from Chapter IV of my book. And less than six months ago, The Economist ran its leading story on the new marketplace reality of “Tech’s Big Dust-Up.”

More importantly, the findings of the various expert reports never seriously contemplate the possibility of competition by differentiation in business models among the platforms. Take privacy, for example. As Peter Klein reasonably writes in his symposium article, we should not be quick to assume market failure. After all, we might have more choice than meets the eye, with Google free but ad-based, and Apple pricy but less-targeted. More generally, Richard Langlois makes a very convincing point that diversification is at the heart of competition between the large digital gatekeepers. We might just be too short-termist—here, digital communications technology might help create a false sense of urgency—to wait for the end state of the Big Tech moligopoly.

Similarly, the expert reports did not really question the real possibility of competition for the purchase of regulation. As in the classic George Stigler paper, where the railroad industry fought motor-trucking competition with state regulation, the businesses that stand to lose most from the digital transformation might be rationally jockeying to convince lawmakers that not all business models are equal, and to steer regulation toward specific business models. Again, though we do not know how to consider this issue, there are signs that a coalition of large news corporations and the publishing oligopoly are behind many antitrust initiatives against digital firms.

Now, as is now clear from these few lines, my cautionary note against antitrust statutorification might be more relevant to the U.S. market. In the EU, sunk investments have been made, expectations have been created, and regulation has now become inevitable. The United States, however, has a chance to get this right. Court cases are the way to go. And unlike what the popular coverage suggests, the recent District Court dismissal of the FTC case far from ruled out the applicability of U.S. antitrust laws to Facebook’s alleged killer acquisitions. On the contrary, the ruling actually contains an invitation to rework a rushed complaint. Perhaps, as Shane Greenstein observed in his retrospective analysis of the U.S. Microsoft case, we would all benefit if we studied more carefully the learning that lies in the cases, rather than haste to produce instant antitrust analysis on Twitter that fits within 280 characters.

Samantha Hoffman, Robert Atkinson and Jennifer Huddleston on American and Chinese approaches to tech policy in the 2020s

The final panel, with the Information Technology and Innovation Foundation’s President Robert Atkinson, the Australian Strategic Policy Institute’s Samantha Hoffman, and the American Action Forum’s Jennifer Huddleston, discussed the role that tech policy in the U.S. and China plays in the geopolitics of the 2020s.

Interrogations concerning the role that economic theory should play in policy decisions are nothing new. Milton Friedman famously drew a distinction between “positive” and “normative” economics, notably arguing that theoretical models were valuable, despite their unrealistic assumptions. Kenneth Arrow and Gerard Debreu’s highly theoretical work on General Equilibrium Theory is widely acknowledged as one of the most important achievements of modern economics.

But for all their intellectual value and academic merit, the use of models to inform policy decisions is not uncontroversial. There is indeed a long and unfortunate history of influential economic models turning out to be poor depictions (and predictors) of real-world outcomes.

This raises a key question: should policymakers use economic models to inform their decisions and, if so, how? This post uses the economics of externalities to illustrate both the virtues and pitfalls of economic modeling. Throughout economic history, externalities have routinely been cited to support claims of market failure and calls for government intervention. However, as explained below, these fears have frequently failed to withstand empirical scrutiny.

Today, similar models are touted to support government intervention in digital industries. Externalities are notably said to prevent consumers from switching between platforms, allegedly leading to unassailable barriers to entry and deficient venture-capital investment. Unfortunately, as explained below, the models that underpin these fears are highly abstracted and far removed from underlying market realities.

Ultimately, this post argues that, while models provide a powerful way of thinking about the world, naïvely transposing them to real-world settings is misguided. This is not to say that models are useless—quite the contrary. Indeed, “falsified” models can shed powerful light on economic behavior that would otherwise prove hard to understand.

Bees

Fears surrounding economic externalities are as old as modern economics. For example, in the 1950s, economists routinely cited bee pollination as a source of externalities and, ultimately, market failure.

The basic argument was straightforward: Bees and orchards provide each other with positive externalities. Bees cross-pollinate flowers and orchards contain vast amounts of nectar upon which bees feed, thus improving honey yields. Accordingly, several famous economists argued that there was a market failure; bees fly where they please and farmers cannot prevent bees from feeding on their blossoming flowers—allegedly causing underinvestment in both. This led James Meade to conclude:

[T]he apple-farmer provides to the beekeeper some of his factors free of charge. The apple-farmer is paid less than the value of his marginal social net product, and the beekeeper receives more than the value of his marginal social net product.

A finding echoed by Francis Bator:

If, then, apple producers are unable to protect their equity in apple-nectar and markets do not impute to apple blossoms their correct shadow value, profit-maximizing decisions will fail correctly to allocate resources at the margin. There will be failure “by enforcement.” This is what I would call an ownership externality. It is essentially Meade’s “unpaid factor” case.

It took more than 20 years and painstaking research by Steven Cheung to conclusively debunk these assertions. So how did economic agents overcome this “insurmountable” market failure?

The answer, it turns out, was extremely simple. While bees do fly where they please, the relative placement of beehives and orchards has a tremendous impact on both fruit and honey yields. This is partly because bees have a very limited mean foraging range (roughly 2-3km). This left economic agents with ample scope to prevent free-riding.

Using these natural sources of excludability, they built a web of complex agreements that internalize the symbiotic virtues of beehives and fruit orchards. To cite Steven Cheung’s research

Pollination contracts usually include stipulations regarding the number and strength of the colonies, the rental fee per hive, the time of delivery and removal of hives, the protection of bees from pesticide sprays, and the strategic placing of hives. Apiary lease contracts differ from pollination contracts in two essential aspects. One is, predictably, that the amount of apiary rent seldom depends on the number of colonies, since the farmer is interested only in obtaining the rent per apiary offered by the highest bidder. Second, the amount of apiary rent is not necessarily fixed. Paid mostly in honey, it may vary according to either the current honey yield or the honey yield of the preceding year.

But what of neighboring orchards? Wouldn’t these entail a more complex externality (i.e., could one orchard free-ride on agreements concluded between other orchards and neighboring apiaries)? Apparently not:

Acknowledging the complication, beekeepers and farmers are quick to point out that a social rule, or custom of the orchards, takes the place of explicit contracting: during the pollination period the owner of an orchard either keeps bees himself or hires as many hives per area as are employed in neighboring orchards of the same type. One failing to comply would be rated as a “bad neighbor,” it is said, and could expect a number of inconveniences imposed on him by other orchard owners. This customary matching of hive densities involves the exchange of gifts of the same kind, which apparently entails lower transaction costs than would be incurred under explicit contracting, where farmers would have to negotiate and make money payments to one another for the bee spillover.

In short, not only did the bee/orchard externality model fail, but it failed to account for extremely obvious counter-evidence. Even a rapid flip through the Yellow Pages (or, today, a search on Google) would have revealed a vibrant market for bee pollination. In short, the bee externalities, at least as presented in economic textbooks, were merely an economic “fable.” Unfortunately, they would not be the last.

The Lighthouse

Lighthouses provide another cautionary tale. Indeed, Henry Sidgwick, A.C. Pigou, John Stuart Mill, and Paul Samuelson all cited the externalities involved in the provision of lighthouse services as a source of market failure.

Here, too, the problem was allegedly straightforward. A lighthouse cannot prevent ships from free-riding on its services when they sail by it (i.e., it is mostly impossible to determine whether a ship has paid fees and to turn off the lighthouse if that is not the case). Hence there can be no efficient market for light dues (lighthouses were seen as a “public good”). As Paul Samuelson famously put it:

Take our earlier case of a lighthouse to warn against rocks. Its beam helps everyone in sight. A businessman could not build it for a profit, since he cannot claim a price from each user. This certainly is the kind of activity that governments would naturally undertake.

He added that:

[E]ven if the operators were able—say, by radar reconnaissance—to claim a toll from every nearby user, that fact would not necessarily make it socially optimal for this service to be provided like a private good at a market-determined individual price. Why not? Because it costs society zero extra cost to let one extra ship use the service; hence any ships discouraged from those waters by the requirement to pay a positive price will represent a social economic loss—even if the price charged to all is no more than enough to pay the long-run expenses of the lighthouse.

More than a century after it was first mentioned in economics textbooks, Ronald Coase finally laid the lighthouse myth to rest—rebutting Samuelson’s second claim in the process.

What piece of evidence had eluded economists for all those years? As Coase observed, contemporary economists had somehow overlooked the fact that large parts of the British lighthouse system were privately operated, and had been for centuries:

[T]he right to operate a lighthouse and to levy tolls was granted to individuals by Acts of Parliament. The tolls were collected at the ports by agents (who might act for several lighthouses), who might be private individuals but were commonly customs officials. The toll varied with the lighthouse and ships paid a toll, varying with the size of the vessel, for each lighthouse passed. It was normally a rate per ton (say 1/4d or 1/2d) for each voyage. Later, books were published setting out the lighthouses passed on different voyages and the charges that would be made.

In other words, lighthouses used a simple physical feature to create “excludability” and prevent free-riding. The main reason ships require lighthouses is to avoid hitting rocks when they make their way to a port. By tying port fees and light dues, lighthouse owners—aided by mild government-enforced property rights—could easily earn a return on their investments, thus disproving the lighthouse free-riding myth.

Ultimately, this meant that a large share of the British lighthouse system was privately operated throughout the 19th century, and this share would presumably have been more pronounced if government-run “Trinity House” lighthouses had not crowded out private investment:

The position in 1820 was that there were 24 lighthouses operated by Trinity House and 22 by private individuals or organizations. But many of the Trinity House lighthouses had not been built originally by them but had been acquired by purchase or as the result of the expiration of a lease.

Of course, this system was not perfect. Some ships (notably foreign ones that did not dock in the United Kingdom) might free-ride on this arrangement. It also entailed some level of market power. The ability to charge light dues meant that prices were higher than the “socially optimal” baseline of zero (the marginal cost of providing light is close to zero). Though it is worth noting that tying port fees and light dues might also have decreased double marginalization, to the benefit of sailors.

Samuelson was particularly weary of this market power that went hand in hand with the private provision of public goods, including lighthouses:

Being able to limit a public good’s consumption does not make it a true-blue private good. For what, after all, are the true marginal costs of having one extra family tune in on the program? They are literally zero. Why then prevent any family which would receive positive pleasure from tuning in on the program from doing so?

However, as Coase explained, light fees represented only a tiny fraction of a ship’s costs. In practice, they were thus unlikely to affect market output meaningfully:

[W]hat is the gain which Samuelson sees as coming from this change in the way in which the lighthouse service is financed? It is that some ships which are now discouraged from making a voyage to Britain because of the light dues would in future do so. As it happens, the form of the toll and the exemptions mean that for most ships the number of voyages will not be affected by the fact that light dues are paid. There may be some ships somewhere which are laid up or broken up because of the light dues, but the number cannot be great, if indeed there are any ships in this category.

Samuelson’s critique also falls prey to the Nirvana Fallacy pointed out by Harold Demsetz: markets might not be perfect, but neither is government intervention. Market power and imperfect appropriability are the two (paradoxical) pitfalls of the first; “white elephants,” underinvestment, and lack of competition (and the information it generates) tend to stem from the latter.

Which of these solutions is superior, in each case, is an empirical question that early economists had simply failed to consider—assuming instead that market failure was systematic in markets that present prima facie externalities. In other words, models were taken as gospel without any circumspection about their relevance to real-world settings.

The Tragedy of the Commons

Externalities were also said to undermine the efficient use of “common pool resources,” such grazing lands, common irrigation systems, and fisheries—resources where one agent’s use diminishes that of others, and where exclusion is either difficult or impossible.

The most famous formulation of this problem is Garret Hardin’s highly influential (over 47,000 cites) “tragedy of the commons.” Hardin cited the example of multiple herdsmen occupying the same grazing ground:

The rational herdsman concludes that the only sensible course for him to pursue is to add another animal to his herd. And another; and another … But this is the conclusion reached by each and every rational herdsman sharing a commons. Therein is the tragedy. Each man is locked into a system that compels him to increase his herd without limit—in a world that is limited. Ruin is the destination toward which all men rush, each pursuing his own best interest in a society that believes in the freedom of the commons.

In more technical terms, each economic agent purportedly exerts an unpriced negative externality on the others, thus leading to the premature depletion of common pool resources. Hardin extended this reasoning to other problems, such as pollution and allegations of global overpopulation.

Although Hardin hardly documented any real-world occurrences of this so-called tragedy, his policy prescriptions were unequivocal:

The most important aspect of necessity that we must now recognize, is the necessity of abandoning the commons in breeding. No technical solution can rescue us from the misery of overpopulation. Freedom to breed will bring ruin to all.

As with many other theoretical externalities, empirical scrutiny revealed that these fears were greatly overblown. In her Nobel-winning work, Elinor Ostrom showed that economic agents often found ways to mitigate these potential externalities markedly. For example, mountain villages often implement rules and norms that limit the use of grazing grounds and wooded areas. Likewise, landowners across the world often set up “irrigation communities” that prevent agents from overusing water.

Along similar lines, Julian Morris and I conjecture that informal arrangements and reputational effects might mitigate opportunistic behavior in the standard essential patent industry.

These bottom-up solutions are certainly not perfect. Many common institutions fail—for example, Elinor Ostrom documents several problematic fisheries, groundwater basins and forests, although it is worth noting that government intervention was sometimes behind these failures. To cite but one example:

Several scholars have documented what occurred when the Government of Nepal passed the “Private Forest Nationalization Act” […]. Whereas the law was officially proclaimed to “protect, manage and conserve the forest for the benefit of the entire country”, it actually disrupted previously established communal control over the local forests. Messerschmidt (1986, p.458) reports what happened immediately after the law came into effect:

Nepalese villagers began freeriding — systematically overexploiting their forest resources on a large scale.

In any case, the question is not so much whether private institutions fail, but whether they do so more often than government intervention. be it regulation or property rights. In short, the “tragedy of the commons” is ultimately an empirical question: what works better in each case, government intervention, propertization, or emergent rules and norms?

More broadly, the key lesson is that it is wrong to blindly apply models while ignoring real-world outcomes. As Elinor Ostrom herself put it:

The intellectual trap in relying entirely on models to provide the foundation for policy analysis is that scholars then presume that they are omniscient observers able to comprehend the essentials of how complex, dynamic systems work by creating stylized descriptions of some aspects of those systems.

Dvorak Keyboards

In 1985, Paul David published an influential paper arguing that market failures undermined competition between the QWERTY and Dvorak keyboard layouts. This version of history then became a dominant narrative in the field of network economics, including works by Joseph Farrell & Garth Saloner, and Jean Tirole.

The basic claim was that QWERTY users’ reluctance to switch toward the putatively superior Dvorak layout exerted a negative externality on the rest of the ecosystem (and a positive externality on other QWERTY users), thus preventing the adoption of a more efficient standard. As Paul David put it:

Although the initial lead acquired by QWERTY through its association with the Remington was quantitatively very slender, when magnified by expectations it may well have been quite sufficient to guarantee that the industry eventually would lock in to a de facto QWERTY standard. […]

Competition in the absence of perfect futures markets drove the industry prematurely into standardization on the wrong system — where decentralized decision making subsequently has sufficed to hold it.

Unfortunately, many of the above papers paid little to no attention to actual market conditions in the typewriter and keyboard layout industries. Years later, Stan Liebowitz and Stephen Margolis undertook a detailed analysis of the keyboard layout market. They almost entirely rejected any notion that QWERTY prevailed despite it being the inferior standard:

Yet there are many aspects of the QWERTY-versus-Dvorak fable that do not survive scrutiny. First, the claim that Dvorak is a better keyboard is supported only by evidence that is both scant and suspect. Second, studies in the ergonomics literature find no significant advantage for Dvorak that can be deemed scientifically reliable. Third, the competition among producers of typewriters, out of which the standard emerged, was far more vigorous than is commonly reported. Fourth, there were far more typing contests than just the single Cincinnati contest. These contests provided ample opportunity to demonstrate the superiority of alternative keyboard arrangements. That QWERTY survived significant challenges early in the history of typewriting demonstrates that it is at least among the reasonably fit, even if not the fittest that can be imagined.

In short, there was little to no evidence supporting the view that QWERTY inefficiently prevailed because of network effects. The falsification of this narrative also weakens broader claims that network effects systematically lead to either excess momentum or excess inertia in standardization. Indeed, it is tempting to characterize all network industries with heavily skewed market shares as resulting from market failure. Yet the QWERTY/Dvorak story suggests that such a conclusion would be premature.

Killzones, Zoom, and TikTok

If you are still reading at this point, you might think that contemporary scholars would know better than to base calls for policy intervention on theoretical externalities. Alas, nothing could be further from the truth.

For instance, a recent paper by Sai Kamepalli, Raghuram Rajan and Luigi Zingales conjectures that the interplay between mergers and network externalities discourages the adoption of superior independent platforms:

If techies expect two platforms to merge, they will be reluctant to pay the switching costs and adopt the new platform early on, unless the new platform significantly outperforms the incumbent one. After all, they know that if the entering platform’s technology is a net improvement over the existing technology, it will be adopted by the incumbent after merger, with new features melded with old features so that the techies’ adjustment costs are minimized. Thus, the prospect of a merger will dissuade many techies from trying the new technology.

Although this key behavioral assumption drives the results of the theoretical model, the paper presents no evidence to support the contention that it occurs in real-world settings. Admittedly, the paper does present evidence of reduced venture capital investments after mergers involving large tech firms. But even on their own terms, this data simply does not support the authors’ behavioral assumption.

And this is no isolated example. Over the past couple of years, several scholars have called for more muscular antitrust intervention in networked industries. A common theme is that network externalities, switching costs, and data-related increasing returns to scale lead to inefficient consumer lock-in, thus raising barriers to entry for potential rivals (here, here, here).

But there are also countless counterexamples, where firms have easily overcome potential barriers to entry and network externalities, ultimately disrupting incumbents.

Zoom is one of the most salient instances. As I have written previously:

To get to where it is today, Zoom had to compete against long-established firms with vast client bases and far deeper pockets. These include the likes of Microsoft, Cisco, and Google. Further complicating matters, the video communications market exhibits some prima facie traits that are typically associated with the existence of network effects.

Along similar lines, Geoffrey Manne and Alec Stapp have put forward a multitude of other examples. These include: The demise of Yahoo; the disruption of early instant-messaging applications and websites; MySpace’s rapid decline; etc. In all these cases, outcomes do not match the predictions of theoretical models.

More recently, TikTok’s rapid rise offers perhaps the greatest example of a potentially superior social-networking platform taking significant market share away from incumbents. According to the Financial Times, TikTok’s video-sharing capabilities and its powerful algorithm are the most likely explanations for its success.

While these developments certainly do not disprove network effects theory, they eviscerate the common belief in antitrust circles that superior rivals are unable to overthrow incumbents in digital markets. Of course, this will not always be the case. As in the previous examples, the question is ultimately one of comparing institutions—i.e., do markets lead to more or fewer error costs than government intervention? Yet this question is systematically omitted from most policy discussions.

In Conclusion

My argument is not that models are without value. To the contrary, framing problems in economic terms—and simplifying them in ways that make them cognizable—enables scholars and policymakers to better understand where market failures might arise, and how these problems can be anticipated and solved by private actors. In other words, models alone cannot tell us that markets will fail, but they can direct inquiries and help us to understand why firms behave the way they do, and why markets (including digital ones) are organized in a given way.

In that respect, both the theoretical and empirical research cited throughout this post offer valuable insights for today’s policymakers.

For a start, as Ronald Coase famously argued in what is perhaps his most famous work, externalities (and market failure more generally) are a function of transaction costs. When these are low (relative to the value of a good), market failures are unlikely. This is perhaps clearest in the “Fable of the Bees” example. Given bees’ short foraging range, there were ultimately few real-world obstacles to writing contracts that internalized the mutual benefits of bees and orchards.

Perhaps more importantly, economic research sheds light on behavior that might otherwise be seen as anticompetitive. The rules and norms that bind farming/beekeeping communities, as well as users of common pool resources, could easily be analyzed as a cartel by naïve antitrust authorities. Yet externality theory suggests they play a key role in preventing market failure.

Along similar lines, mergers and acquisitions (as well as vertical integration, more generally) can reduce opportunism and other externalities that might otherwise undermine collaboration between firms (here, here and here). And much of the same is true for certain types of unilateral behavior. Tying video games to consoles (and pricing the console below cost) can help entrants overcome network externalities that might otherwise shield incumbents. Likewise, Google tying its proprietary apps to the open source Android operating system arguably enabled it to earn a return on its investments, thus overcoming the externality problem that plagues open source software.

All of this raises a tantalizing prospect that deserves far more attention than it is currently given in policy circles: authorities around the world are seeking to regulate the tech space. Draft legislation has notably been tabled in the United States, European Union and the United Kingdom. These draft bills would all make it harder for large tech firms to implement various economic hierarchies, including mergers and certain contractual arrangements.

This is highly paradoxical. If digital markets are indeed plagued by network externalities and high transaction costs, as critics allege, then preventing firms from adopting complex hierarchies—which have traditionally been seen as a way to solve externalities—is just as likely to exacerbate problems. In other words, like the economists of old cited above, today’s policymakers appear to be focusing too heavily on simple models that predict market failure, and far too little on the mechanisms that firms have put in place to thrive within this complex environment.

The bigger picture is that far more circumspection is required when using theoretical models in real-world policy settings. Indeed, as Harold Demsetz famously put it, the purpose of normative economics is not so much to identify market failures, but to help policymakers determine which of several alternative institutions will deliver the best outcomes for consumers:

This nirvana approach differs considerably from a comparative institution approach in which the relevant choice is between alternative real institutional arrangements. In practice, those who adopt the nirvana viewpoint seek to discover discrepancies between the ideal and the real and if discrepancies are found, they deduce that the real is inefficient. Users of the comparative institution approach attempt to assess which alternative real institutional arrangement seems best able to cope with the economic problem […].
