Archives For Amazon

The wave of populist antitrust that has been embraced by regulators and legislators in the United States, United Kingdom, European Union, and other jurisdictions rests on the assumption that currently dominant platforms occupy entrenched positions that only government intervention can dislodge. Following this view, Facebook will forever dominate social networking, Amazon will forever dominate cloud computing, Uber and Lyft will forever dominate ridesharing, and Amazon and Netflix will forever dominate streaming. This assumption of platform invincibility is so well-established that some policymakers advocate significant interventions without making any meaningful inquiry into whether a seemingly dominant platform actually exercises market power.

Yet this assumption is not supported by historical patterns in platform markets. It is true that network effects drive platform markets toward “winner-take-most” outcomes. But the winner is often toppled quickly and without much warning. There is no shortage of examples.

In 2007, a columnist in The Guardian observed that “it may already be too late for competitors to dislodge MySpace” and quoted an economist as authority for the proposition that “MySpace is well on the way to becoming … a natural monopoly.” About one year later, Facebook had overtaken MySpace “monopoly” in the social-networking market. Similarly, it was once thought that Blackberry would forever dominate the mobile-communications device market, eBay would always dominate the online e-commerce market, and AOL would always dominate the internet-service-portal market (a market that no longer even exists). The list of digital dinosaurs could go on.

All those tech leaders were challenged by entrants and descended into irrelevance (or reduced relevance, in eBay’s case). This occurred through the force of competition, not government intervention.

Why This Time is Probably Not Different

Given this long line of market precedents, current legislative and regulatory efforts to “restore” competition through extensive intervention in digital-platform markets require that we assume that “this time is different.” Just as that slogan has been repeatedly rebutted in the financial markets, so too is it likely to be rebutted in platform markets. 

There is already supporting evidence. 

In the cloud market, Amazon’s AWS now faces vigorous competition from Microsoft Azure and Google Cloud. In the streaming market, Amazon and Netflix face stiff competition from Disney+ and Apple TV+, just to name a few well-resourced rivals. In the social-networking market, Facebook now competes head-to-head with TikTok and seems to be losing. The market power once commonly attributed to leading food-delivery platforms such as Grubhub, UberEats, and DoorDash is implausible after persistent losses in most cases, and the continuous entry of new services into a rich variety of local and product-market niches.

Those who have advocated antitrust intervention on a fast-track schedule may remain unconvinced by these inconvenient facts. But the market is not. 

Investors have already recognized Netflix’s vulnerability to competition, as reflected by a 35% fall in its stock price on April 20 and a decline of more than 60% over the past 12 months. Meta, Facebook’s parent, also experienced a reappraisal, falling more than 26% on Feb. 3 and more than 35% in the past 12 months. Uber, the pioneer of the ridesharing market, has declined by almost 50% over the past 12 months, while Lyft, its principal rival, has lost more than 60% of its value. These price freefalls suggest that antitrust populists may be pursuing solutions to a problem that market forces are already starting to address.

The Forgotten Curse of the Incumbent

For some commentators, the sharp downturn in the fortunes of the so-called “Big Tech” firms would not come as a surprise.

It has long been observed by some scholars and courts that a dominant firm “carries the seeds of its own destruction”—a phrase used by then-professor and later-Judge Richard Posner, writing in the University of Chicago Law Review in 1971. The reason: a dominant firm is liable to exhibit high prices, mediocre quality, or lackluster innovation, which then invites entry by more adept challengers. However, this view has been dismissed as outdated in digital-platform markets, where incumbents are purportedly protected by network effects and switching costs that make it difficult for entrants to attract users. Depending on the set of assumptions selected by an economic modeler, each contingency is equally plausible in theory.

The plunging values of leading platforms supplies real-world evidence that favors the self-correction hypothesis. It is often overlooked that network effects can work in both directions, resulting in a precipitous fall from market leader to laggard. Once users start abandoning a dominant platform for a new competitor, network effects operating in reverse can cause a “run for the exits” that leaves the leader with little time to recover. Just ask Nokia, the world’s leading (and seemingly unbeatable) smartphone brand until the Apple iPhone came along.

Why Market Self-Correction Outperforms Regulatory Correction

Market self-correction inherently outperforms regulatory correction: it operates far more rapidly and relies on consumer preferences to reallocate market leadership—a result perfectly consistent with antitrust’s mission to preserve “competition on the merits.” In contrast, policymakers can misdiagnose the competitive effects of business practices; are susceptible to the influence of private interests (especially those that are unable to compete on the merits); and often mispredict the market’s future trajectory. For Exhibit A, see the protracted antitrust litigation by the U.S. Department against IBM, which started in 1975 and ended in withdrawal of the suit in 1982. Given the launch of the Apple II in 1977, the IBM PC in 1981, and the entry of multiple “PC clones,” the forces of creative destruction swiftly displaced IBM from market leadership in the computing industry.

Regulators and legislators around the world have emphasized the urgency of taking dramatic action to correct claimed market failures in digital environments, casting aside prudential concerns over the consequences if any such failure proves to be illusory or temporary. 

But the costs of regulatory failure can be significant and long-lasting. Markets must operate under unnecessary compliance burdens that are difficult to modify. Regulators’ enforcement resources are diverted, and businesses are barred from adopting practices that would benefit consumers. In particular, proposed breakup remedies advocated by some policymakers would undermine the scale economies that have enabled platforms to push down prices, an important consideration in a time of accelerating inflation.

Conclusion

The high concentration levels and certain business practices in digital-platform markets certainly raise important concerns as a matter of antitrust (as well as privacy, intellectual property, and other bodies of) law. These concerns merit scrutiny and may necessitate appropriately targeted interventions. Yet, any policy steps should be anchored in the factually grounded analysis that has characterized decades of regulatory and judicial action to implement the antitrust laws with appropriate care. Abandoning this nuanced framework for a blunt approach based on reflexive assumptions of market power is likely to undermine, rather than promote, the public interest in competitive markets.

Sens. Amy Klobuchar (D-Minn.) and Chuck Grassley (R-Iowa)—cosponsors of the American Innovation Online and Choice Act, which seeks to “rein in” tech companies like Apple, Google, Meta, and Amazon—contend that “everyone acknowledges the problems posed by dominant online platforms.”

In their framing, it is simply an acknowledged fact that U.S. antitrust law has not kept pace with developments in the digital sector, allowing a handful of Big Tech firms to exploit consumers and foreclose competitors from the market. To address the issue, the senators’ bill would bar “covered platforms” from engaging in a raft of conduct, including self-preferencing, tying, and limiting interoperability with competitors’ products.

That’s what makes the open letter to Congress published late last month by the usually staid American Bar Association’s (ABA) Antitrust Law Section so eye-opening. The letter is nothing short of a searing critique of the legislation, which the section finds to be poorly written, vague, and departing from established antitrust-law principles.

The ABA, of course, has a reputation as an independent, highly professional, and heterogenous group. The antitrust section’s membership includes not only in-house corporate counsel, but lawyers from nonprofits, consulting firms, federal and state agencies, judges, and legal academics. Given this context, the comments must be read as a high-level judgment that recent legislative and regulatory efforts to “discipline” tech fall outside the legal mainstream and would come at the cost of established antitrust principles, legal precedent, transparency, sound economic analysis, and ultimately consumer welfare.

The Antitrust Section’s Comments

As the ABA Antitrust Law Section observes:

The Section has long supported the evolution of antitrust law to keep pace with evolving circumstances, economic theory, and empirical evidence. Here, however, the Section is concerned that the Bill, as written, departs in some respects from accepted principles of competition law and in so doing risks causing unpredicted and unintended consequences.

Broadly speaking, the section’s criticisms fall into two interrelated categories. The first relates to deviations from antitrust orthodoxy and the principles that guide enforcement. The second is a critique of the AICOA’s overly broad language and ambiguous terminology.

Departing from established antitrust-law principles

Substantively, the overarching concern expressed by the ABA Antitrust Law Section is that AICOA departs from the traditional role of antitrust law, which is to protect the competitive process, rather than choosing to favor some competitors at the expense of others. Indeed, the section’s open letter observes that, out of the 10 categories of prohibited conduct spelled out in the legislation, only three require a “material harm to competition.”

Take, for instance, the prohibition on “discriminatory” conduct. As it stands, the bill’s language does not require a showing of harm to the competitive process. It instead appears to enshrine a freestanding prohibition of discrimination. The bill targets tying practices that are already prohibited by U.S. antitrust law, but while similarly eschewing the traditional required showings of market power and harm to the competitive process. The same can be said, mutatis mutandis, for “self-preferencing” and the “unfair” treatment of competitors.

The problem, the section’s letter to Congress argues, is not only that this increases the teleological chasm between AICOA and the overarching goals and principles of antitrust law, but that it can also easily lead to harmful unintended consequences. For instance, as the ABA Antitrust Law Section previously observed in comments to the Australian Competition and Consumer Commission, a prohibition of pricing discrimination can limit the extent of discounting generally. Similarly, self-preferencing conduct on a platform can be welfare-enhancing, while forced interoperability—which is also contemplated by AICOA—can increase prices for consumers and dampen incentives to innovate. Furthermore, some of these blanket prohibitions are arguably at loggerheads with established antitrust doctrine, such as in, e.g., Trinko, which established that even monopolists are generally free to decide with whom they will deal.

In response to the above, the ABA Antitrust Law Section (reasonably) urges Congress explicitly to require an effects-based showing of harm to the competitive process as a prerequisite for all 10 of the infringements contemplated in the AICOA. This also means disclaiming generalized prohibitions of “discrimination” and of “unfairness” and replacing blanket prohibitions (such as the one for self-preferencing) with measured case-by-case analysis.

Arguably, the reason why the Klobuchar-Grassley bill can so seamlessly exclude or redraw such a central element of antitrust law as competitive harm is because it deliberately chooses to ignore another, preceding one. Namely, the bill omits market power as a requirement for a finding of infringement or for the legislation’s equally crucial designation as a “covered platform.” It instead prescribes size metrics—number of users, market capitalization—to define which platforms are subject to intervention. Such definitions cast an overly wide net that can potentially capture consumer-facing conduct that doesn’t have the potential to harm competition at all.

It is precisely for this reason that existing antitrust laws are tethered to market power—i.e., because it long has been recognized that only companies with market power can harm competition. As John B. Kirkwood of Seattle University School of Law has written:

Market power’s pivotal role is clear…This concept is central to antitrust because it distinguishes firms that can harm competition and consumers from those that cannot.

In response to the above, the ABA Antitrust Law Section (reasonably) urges Congress explicitly to require an effects-based showing of harm to the competitive process as a prerequisite for all 10 of the infringements contemplated in the AICOA. This also means disclaiming generalized prohibitions of “discrimination” and of “unfairness” and replacing blanket prohibitions (such as the one for self-preferencing) with measured case-by-case analysis.

Opaque language for opaque ideas

Another underlying issue is that the Klobuchar-Grassley bill is shot through with indeterminate language and fuzzy concepts that have no clear limiting principles. For instance, in order either to establish liability or to mount a successful defense to an alleged violation, the bill relies heavily on inherently amorphous terms such as “fairness,” “preferencing,” and “materiality,” or the “intrinsic” value of a product. But as the ABA Antitrust Law Section letter rightly observes, these concepts are not defined in the bill, nor by existing antitrust case law. As such, they inject variability and indeterminacy into how the legislation would be administered.

Moreover, it is also unclear how some incommensurable concepts will be weighed against each other. For example, how would concerns about safety and security be weighed against prohibitions on self-preferencing or requirements for interoperability? What is a “core function” and when would the law determine it has been sufficiently “enhanced” or “maintained”—requirements the law sets out to exempt certain otherwise prohibited behavior? The lack of linguistic and conceptual clarity not only explodes legal certainty, but also invites judicial second-guessing into the operation of business decisions, something against which the U.S. Supreme Court has long warned.

Finally, the bill’s choice of language and recent amendments to its terminology seem to confirm the dynamic discussed in the previous section. Most notably, the latest version of AICOA replaces earlier language invoking “harm to the competitive process” with “material harm to competition.” As the ABA Antitrust Law Section observes, this “suggests a shift away from protecting the competitive process towards protecting individual competitors.” Indeed, “material harm to competition” deviates from established categories such as “undue restraint of trade” or “substantial lessening of competition,” which have a clear focus on the competitive process. As a result, it is not unreasonable to expect that the new terminology might be interpreted as meaning that the actionable standard is material harm to competitors.

In its letter, the antitrust section urges Congress not only to define more clearly the novel terminology used in the bill, but also to do so in a manner consistent with existing antitrust law. Indeed:

The Section further recommends that these definitions direct attention to analysis consistent with antitrust principles: effects-based inquiries concerned with harm to the competitive process, not merely harm to particular competitors

Conclusion

The AICOA is a poorly written, misguided, and rushed piece of regulation that contravenes both basic antitrust-law principles and mainstream economic insights in the pursuit of a pre-established populist political goal: punishing the success of tech companies. If left uncorrected by Congress, these mistakes could have potentially far-reaching consequences for innovation in digital markets and for consumer welfare. They could also set antitrust law on a regressive course back toward a policy of picking winners and losers.

After years of debate and negotiations, European Lawmakers have agreed upon what will most likely be the final iteration of the Digital Markets Act (“DMA”), following the March 24 final round of “trilogue” talks. 

For the uninitiated, the DMA is one in a string of legislative proposals around the globe intended to “rein in” tech companies like Google, Amazon, Facebook, and Apple through mandated interoperability requirements and other regulatory tools, such as bans on self-preferencing. Other important bills from across the pond include the American Innovation and Choice Online Act, the ACCESS Act, and the Open App Markets Act

In many ways, the final version of the DMA represents the worst possible outcome, given the items that were still up for debate. The Commission caved to some of the Parliament’s more excessive demands—such as sweeping interoperability provisions that would extend not only to “ancillary” services, such as payments, but also to messaging services’ basic functionalities. Other important developments include the addition of voice assistants and web browsers to the list of Core Platform Services (“CPS”), and symbolically higher “designation” thresholds that further ensure the act will apply overwhelmingly to just U.S. companies. On a brighter note, lawmakers agreed that companies could rebut their designation as “gatekeepers,” though it remains to be seen how feasible that will be in practice. 

We offer here an overview of the key provisions included in the final version of the DMA and a reminder of the shaky foundations it rests on.

Interoperability

Among the most important of the DMA’s new rules concerns mandatory interoperability among online platforms. In a nutshell, digital platforms that are designated as “gatekeepers” will be forced to make their services “interoperable” (i.e., compatible) with those of rivals. It is argued that this will make online markets more contestable and thus boost consumer choice. But as ICLE scholars have been explaining for some time, this is unlikely to be the case (here, here, and here). Interoperability is not the panacea EU legislators claim it to be. As former ICLE Director of Competition Policy Sam Bowman has written, there are many things that could be interoperable, but aren’t. The reason is that interoperability comes with costs as well as benefits. For instance, 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 the market and for consumers to be able to choose among them. Economists Michael L. Katz and Carl Shapiro concur:

Although compatibility has obvious benefits, obtaining and maintaining compatibility often involves a sacrifice in terms of product variety or restraints on innovation.

There are other potential downsides to interoperability.  For instance, a given set of interoperable standards might be too costly to implement and/or maintain; it might preclude certain pricing models that increase output; or it might compromise some element of a product or service that offers benefits specifically because it is not interoperable (such as, e.g., security features). Consumers may also genuinely prefer closed (i.e., non-interoperable) platforms. Indeed: “open” and “closed” are not synonyms for “good” and “bad.” Instead, as Boston University’s Andrei Hagiu has shown, there are fundamental welfare tradeoffs at play that belie simplistic characterizations of one being inherently superior to the other. 

Further, as Sam Bowman observed, narrowing choice through a more curated experience can also be valuable for users, as it frees them from having to research every possible option every time they buy or use some product (if you’re unconvinced, try turning off your spam filter for a couple of days). Instead, the relevant choice consumers exercise might be in choosing among brands. In sum, where interoperability is a desirable feature, consumer preferences will tend to push for more of it. However, it is fundamentally misguided to treat mandatory interoperability as a cure-all elixir or a “super tool” of “digital platform governance.” In a free-market economy, it is not—or, it should not—be up to courts and legislators to substitute for businesses’ product-design decisions and consumers’ revealed preferences with their own, based on diffuse notions of “fairness.” After all, if we could entrust such decisions to regulators, we wouldn’t need markets or competition in the first place.

Of course, it was always clear that the DMA would contemplate some degree of mandatory interoperability – indeed, this was arguably the new law’s biggest selling point. What was up in the air until now was the scope of such obligations. The Commission had initially pushed for a comparatively restrained approach, requiring interoperability “only” in ancillary services, such as payment systems (“vertical interoperability”). By contrast, the European Parliament called for more expansive requirements that would also encompass social-media platforms and other messaging services (“horizontal interoperability”). 

The problem with such far-reaching interoperability requirements is that they are fundamentally out of pace with current privacy and security capabilities. As ICLE Senior Scholar Mikolaj Barczentewicz has repeatedly argued, the Parliament’s insistence on going significantly beyond the original DMA’s proposal and mandating interoperability of messaging services is overly broad and irresponsible. Indeed, as Mikolaj notes, the “likely result is less security and privacy, more expenses, and less innovation.”The DMA’s defensers would retort that the law allows gatekeepers to do what is “strictly necessary” (Council) or “indispensable” (Parliament) to protect safety and privacy (it is not yet clear which wording the final version has adopted). Either way, however, the standard may be too high and companies may very well offer lower security to avoid liability for adopting measures that would be judged by the Commission and the courts as going beyond what is “strictly necessary” or “indispensable.” These safeguards will inevitably be all the more indeterminate (and thus ineffectual) if weighed against other vague concepts at the heart of the DMA, such as “fairness.”

Gatekeeper Thresholds and the Designation Process

Another important issue in the DMA’s construction concerns the designation of what the law deems “gatekeepers.” Indeed, the DMA will only apply to such market gatekeepers—so-designated because they meet certain requirements and thresholds. Unfortunately, the factors that the European Commission will consider in conducting this designation process—revenues, market capitalization, and user base—are poor proxies for firms’ actual competitive position. This is not surprising, however, as the procedure is mainly designed to ensure certain high-profile (and overwhelmingly American) platforms are caught by the DMA.

From this perspective, the last-minute increase in revenue and market-capitalization thresholds—from 6.5 billion euros to 7.5 billion euros, and from 65 billion euros to 75 billion euros, respectively—won’t change the scope of the companies covered by the DMA very much. But it will serve to confirm what we already suspected: that the DMA’s thresholds are mostly tailored to catch certain U.S. companies, deliberately leaving out EU and possibly Chinese competitors (see here and here). Indeed, what would have made a difference here would have been lowering the thresholds, but this was never really on the table. Ultimately, tilting the European Union’s playing field against its top trading partner, in terms of exports and trade balance, is economically, politically, and strategically unwise.

As a consolation of sorts, it seems that the Commission managed to squeeze in a rebuttal mechanism for designated gatekeepers. Imposing far-reaching obligations on companies with no  (or very limited) recourse to escape the onerous requirements of the DMA would be contrary to the basic principles of procedural fairness. Still, it remains to be seen how this mechanism will be articulated and whether it will actually be viable in practice.

Double (and Triple?) Jeopardy

Two recent judgments from the European Court of Justice (ECJ)—Nordzucker and bpost—are likely to underscore the unintended effects of cumulative application of both the DMA and EU and/or national competition laws. The bpost decision is particularly relevant, because it lays down the conditions under which cases that evaluate the same persons and the same facts in two separate fields of law (sectoral regulation and competition law) do not violate the principle of ne bis in idem, also known as “double jeopardy.” As paragraph 51 of the judgment establishes:

  1. There must be precise rules to determine which acts or omissions are liable to be subject to duplicate proceedings;
  2. The two sets of proceedings must have been conducted in a sufficiently coordinated manner and within a similar timeframe; and
  3. The overall penalties must match the seriousness of the offense. 

It is doubtful whether the DMA fulfills these conditions. This is especially unfortunate considering the overlapping rules, features, and goals among the DMA and national-level competition laws, which are bound to lead to parallel procedures. In a word: expect double and triple jeopardy to be hotly litigated in the aftermath of the DMA.

Of course, other relevant questions have been settled which, for reasons of scope, we will have to leave for another time. These include the level of fines (up to 10% worldwide revenue, or 20% in the case of repeat offenses); the definition and consequences of systemic noncompliance (it seems that the Parliament’s draconian push for a general ban on acquisitions in case of systemic noncompliance has been dropped); and the addition of more core platform services (web browsers and voice assistants).

The DMA’s Dubious Underlying Assumptions

The fuss and exhilaration surrounding the impending adoption of the EU’s most ambitious competition-related proposal in decades should not obscure some of the more dubious assumptions which underpin it, such as that:

  1. It is still unclear that intervention in digital markets is necessary, let alone urgent.
  2. Even if it were clear, there is scant evidence to suggest that tried and tested ex post instruments, such as those envisioned in EU competition law, are not up to the task.
  3. Even if the prior two points had been established beyond any reasonable doubt (which they haven’t), it is still far from clear that DMA-style ex ante regulation is the right tool to address potential harms to competition and to consumers that arise in digital markets.

It is unclear that intervention is necessary

Despite a mounting moral panic around and zealous political crusading against Big Tech (an epithet meant to conjure antipathy and distrust), it is still unclear that intervention in digital markets is necessary. Much of the behavior the DMA assumes to be anti-competitive has plausible pro-competitive justifications. Self-preferencing, for instance, is a normal part of how platforms operate, both to improve the value of their core products and to earn returns to reinvest in their development. As ICLE’s Dirk Auer points out, since platforms’ incentives are to maximize the value of their entire product ecosystem, those that preference their own products frequently end up increasing the total market’s value by growing the share of users of a particular product (the example of Facebook’s integration of Instagram is a case in point). Thus, while self-preferencing may, in some cases, be harmful, a blanket presumption of harm is thoroughly unwarranted

Similarly, the argument that switching costs and data-related increasing returns to scale (in fact, data generally entails diminishing returns) have led to consumer lock-in and thereby raised entry barriers has also been exaggerated to epic proportions (pun intended). As we have discussed previously, there are plenty of counterexamples where firms have easily overcome seemingly “insurmountable” barriers to entry, switching costs, and network effects to disrupt incumbents. 

To pick a recent case: how many of us had heard of Zoom before the pandemic? Where was TikTok three years ago? (see here for a multitude of other classic examples, including Yahoo and Myspace).

Can you really say, with a straight face, that switching costs between messaging apps are prohibitive? I’m not even that active and I use at least six such apps on a daily basis: Facebook Messenger, Whatsapp, Instagram, Twitter, Viber, Telegram, and Slack (it took me all of three minutes to download and start using Slack—my newest addition). In fact, chances are that, like me, you have always multihomed nonchalantly and had never even considered that switching costs were impossibly high (or that they were a thing) until the idea that you were “locked-in” by Big Tech was drilled into your head by politicians and other busybodies looking for trophies to adorn their walls.

What about the “unprecedented,” quasi-fascistic levels of economic concentration? First, measures of market concentration are sometimes anchored in flawed methodology and market definitions  (see, e.g., Epic’s insistence that Apple is a monopolist in the market for operating systems, conveniently ignoring that competition occurs at the smartphone level, where Apple has a worldwide market share of 15%—see pages 45-46 here). But even if such measurements were accurate, high levels of concentration don’t necessarily mean that firms do not face strong competition. In fact, as Nicolas Petit has shown, tech companies compete vigorously against each other across markets.

But perhaps the DMA’s raison d’etre rests less on market failure, but rather on a legal or enforcement failure? This, too, is misguided.

EU competition law is already up to the task

As Giuseppe Colangelo has argued persuasively (here and here), it is not at all clear that ex post competition regulation is insufficient to tackle anti-competitive behavior in the digital sector:

Ongoing antitrust investigations demonstrate that standard competition law still provides a flexible framework to scrutinize several practices described as new and peculiar to app stores. 

The recent Google Shopping decision, in which the Commission found that Google had abused its dominant position by preferencing its own online-shopping service in Google Search results, is a case in point (the decision was confirmed by the General Court and is now pending review before the European Court of Justice). The “self-preferencing” category has since been applied by other EU competition authorities. The Italian competition authority, for instance, fined Amazon 1 billion euros for preferencing its own distribution service, Fulfilled by Amazon, on the Amazon marketplace (i.e., Amazon.it). Thus, Article 102, which includes prohibitions on “applying dissimilar conditions to similar transactions,” appears sufficiently flexible to cover self-preferencing, as well as other potentially anti-competitive offenses relevant to digital markets (e.g., essential facilities).

For better or for worse, EU competition law has historically been sufficiently pliable to serve a range of goals and values. It has also allowed for experimentation and incorporated novel theories of harm and economic insights. Here, the advantage of competition law is that it allows for a more refined, individualized approach that can avoid some of the pitfalls of applying a one-size fits all model across all digital platforms. Those pitfalls include: harming consumers, jeopardizing the business models of some of the most successful and pro-consumer companies in existence, and ignoring the differences among platforms, such as between Google and Apple’s app stores. I turn to these issues next.

Ex ante regulation probably isn’t the right tool

Even if it were clear that intervention is necessary and that existing competition law was insufficient, it is not clear that the DMA is the right regulatory tool to address any potential harms to competition and consumers that may arise in the digital markets. Here, legislators need to be wary of unintended consequences, trade-offs, and regulatory fallibility. For one, It is possible that the DMA will essentially consolidate the power of tech platforms, turning them into de facto public utilities. This will not foster competition, but rather will make smaller competitors systematically dependent on so-called gatekeepers. Indeed, why become the next Google if you can just free ride off of the current Google? Why download an emerging messaging app if you can already interact with its users through your current one? In a way, then, the DMA may become a self-fulfilling prophecy. 

Moreover, turning closed or semi-closed platforms such as the iOS into open platforms more akin to Android blurs the distinctions among products and dampens interbrand competition. It is a supreme paradox that interoperability and sideloading requirements purportedly give users more choice by taking away the option of choosing a “walled garden” model. As discussed above, overriding the revealed preferences of millions of users is neither pro-competitive nor pro-consumer (but it probably favors some competitors at the expense of those two things). 

Nor are many of the other obligations contemplated in the DMA necessarily beneficial to consumers. Do users really not want to have default apps come preloaded on their devices and instead have to download and install them manually? Ditto for operating systems. What is the point of an operating system if it doesn’t come with certain functionalities, such as a web browser? What else should we unbundle—keyboard on iOS? Flashlight? Do consumers really want to choose from dozens of app stores when turning on their new phone for the first time? Do they really want to have their devices cluttered with pointless split-screens? Do users really want to find all their contacts (and be found by all their contacts) across all messaging services? (I switched to Viber because I emphatically didn’t.) Do they really want to have their privacy and security compromised because of interoperability requirements?Then there is the question of regulatory fallibility. As Alden Abott has written on the DMA and other ex ante regulatory proposals aimed at “reining in” tech companies:

Sorely missing from these regulatory proposals is any sense of the fallibility of regulation. Indeed, proponents of new regulatory proposals seem to implicitly assume that government regulation of platforms will enhance welfare, ignoring real-life regulatory costs and regulatory failures (see here, for example). 

This brings us back to the second point: without evidence that antitrust law is “not up to the task,” far-reaching and untested regulatory initiatives with potentially high error costs are put forth as superior to long-established, consumer-based antitrust enforcement. Yes, antitrust may have downsides (e.g., relative indeterminacy and slowness), but these pale in comparison to the DMA’s (e.g., large error costs resulting from high information requirements, rent-seeking, agency capture).

Conclusion

The DMA is an ambitious piece of regulation purportedly aimed at ensuring “fair and open digital markets.” This implies that markets are not fair and open; or that they risk becoming unfair and closed absent far-reaching regulatory intervention at EU level. However, it is unclear to what extent such assumptions are borne out by the reality of markets. Are digital markets really closed? Are they really unfair? If so, is it really certain that regulation is necessary? Has antitrust truly proven insufficient? It also implies that DMA-style ex ante regulation is necessary to tackle it, and that the costs won’t outweigh the benefits. These are heroic assumptions that have never truly been seriously put to the test. 

Considering such brittle empirical foundations, the DMA was always going to be a contentious piece of legislation. However, there was always the hope that EU legislators would show restraint in the face of little empirical evidence and high error costs. Today, these hopes have been dashed. With the adoption of the DMA, the Commission, Council, and the Parliament have arguably taken a bad piece of legislation and made it worse. The interoperability requirements in messaging services, which are bound to be a bane for user privacy and security, are a case in point.

After years trying to anticipate the whims of EU legislators, we finally know where we’re going, but it’s still not entirely sure why we’re going there.

As the European Union’s Digital Markets Act (DMA) has entered the final stage of its approval process, one matter the inter-institutional negotiations appears likely to leave unresolved is how the DMA’s the relationship with competition law affects the very rationale and legal basis for the intervention. 

The DMA is explicitly grounded on the questionable assumption that competition law alone is insufficient to rein in digital gatekeepers. Accordingly, EU lawmakers have declared the proposal to be a necessary regulatory intervention that will complement antitrust rules by introducing a set of ex ante obligations.

To support this line of reasoning, the DMA’s drafters insist that it protects a different legal interest from antitrust. Indeed, the intervention is ostensibly grounded in Article 114 of the Treaty on the Functioning of the European Union (TFEU), rather than Article 103—the article that spells out the implementation of competition law. Pursuant to Article 114, the DMA opts for centralized enforcement at the EU level to ensure harmonized implementation of the new rules.

It has nonetheless been clear from the very beginning that the DMA lacks a distinct purpose. Indeed, the interests it nominally protects (the promotion of fairness and contestability) do not differ from the substance and scope of competition law. The European Parliament has even suggested that the law’s aims should also include fostering innovation and increasing consumer welfare, which also are within the purview of competition law. Moreover, the DMA’s obligations focus on practices that have already been the subject of past and ongoing antitrust investigations.

Where the DMA differs in substance from competition law is simply that it would free enforcers from the burden of standard antitrust analysis. The law is essentially a convenient shortcut that would dispense with the need to define relevant markets, prove dominance, and measure market effects (see here). It essentially dismisses economic analysis and the efficiency-oriented consumer welfare test in order to lower the legal standards and evidentiary burdens needed to bring an investigation.

Acknowledging the continuum between competition law and the DMA, the European Competition Network and some member states (self-appointed as “friends of an effective DMA”) have proposed empowering national competition authorities (NCAs) to enforce DMA obligations.

Against this background, my new ICLE working paper pursues a twofold goal. First, it aims to show how, because of its ambiguous relationship with competition law, the DMA falls short of its goal of preventing regulatory fragmentation. Moreover, despite having significant doubts about the DMA’s content and rationale, I argue that fully centralized enforcement at the EU level should be preserved and that frictions with competition law would be better confined by limiting the law’s application to a few large platforms that are demonstrably able to orchestrate an ecosystem.

Welcome to the (Regulatory) Jungle

The DMA will not replace competition rules. It will instead be implemented alongside them, creating several overlapping layers of regulation. Indeed, my paper broadly illustrates how the very same practices that are targeted by the DMA may also be investigated by NCAs under European and national-level competition laws, under national competition laws specific to digital markets, and under national rules on economic dependence.

While the DMA nominally prohibits EU member states from imposing additional obligations on gatekeepers, member states remain free to adapt their competition laws to digital markets in accordance with the leeway granted by Article 3(3) of the Modernization Regulation. Moreover, NCAs may be eager to exploit national rules on economic dependence to tackle perceived imbalances of bargaining power between online platforms and their business counterparties.

The risk of overlap with competition law is also fostered by the DMA’s designation process, which may further widen the law’s scope in the future in terms of what sorts of digital services and firms may fall under the law’s rubric. As more and more industries explore platform business models, the DMA would—without some further constraints on its scope—be expected to cover a growing number of firms, including those well outside Big Tech or even native tech companies.

As a result, the European regulatory landscape could become even more fragmented in the post-DMA world. The parallel application of the DMA and antitrust rules poses the risks of double jeopardy (see here) and of conflicting decisions.

A Fully Centralized and Ecosystem-Based Regulatory Regime

To counter the risk that digital-market activity will be subject to regulatory double jeopardy and conflicting decisions across EU jurisdictions, DMA enforcement should not only be fully centralized at the EU level, but that centralization should be strengthened. This could be accomplished by empowering the Commission with veto rights, as was requested by the European Parliament.

This veto power should certainly extend to national measures targeting gatekeepers that run counter to the DMA or to decisions adopted by the Commission under the DMA. But it should also include prohibiting national authorities from carrying out investigations on their own initiative without prior authorization by the Commission.

Moreover, it will also likely be necessary to significantly redefine the DMA’s scope. Notably, EU leaders could mitigate the risk of fragmentation from the DMA’s frictions with competition law by circumscribing the law to ecosystem-related issues. This would effectively limit its application to a few large platforms who are demonstrably able to orchestrate an ecosystem. It also would reinstate the DMA’s original justification, which was to address the emergence of a few large platforms who are able act as gatekeepers and enjoy an entrenched position as a result of conglomerate ecosystems.

Changes to the designation process should also be accompanied by confining the list of ex ante obligations the law imposes. These should reflect relevant differences in platforms’ business models and be tailored to the specific firm under scrutiny, rather than implementing a one-size-fits-all approach.

There are compelling arguments against the policy choice to regulate platforms and their ecosystems like utilities. The suggested adaptations would at least acknowledge the regulatory nature of the DMA, removing the suspicion that it is just an antitrust intervention vested by regulation.

The Senate Judiciary Committee is set to debate S. 2992, the American Innovation and Choice Online Act (or AICOA) during a markup session Thursday. If passed into law, the bill would force online platforms to treat rivals’ services as they would their own, while ensuring their platforms interoperate seamlessly.

The bill marks the culmination of misguided efforts to bring Big Tech to heel, regardless of the negative costs imposed upon consumers in the process. ICLE scholars have written about these developments in detail since the bill was introduced in October.

Below are 10 significant misconceptions that underpin the legislation.

1. There Is No Evidence that Self-Preferencing Is Generally Harmful

Self-preferencing is a normal part of how platforms operate, both to improve the value of their core products and to earn returns so that they have reason to continue investing in their development.

Platforms’ incentives are to maximize the value of their entire product ecosystem, which includes both the core platform and the services attached to it. Platforms that preference their own products frequently end up increasing the total market’s value by growing the share of users of a particular product. Those that preference inferior products end up hurting their attractiveness to users of their “core” product, exposing themselves to competition from rivals.

As Geoff Manne concludes, the notion that it is harmful (notably to innovation) when platforms enter into competition with edge providers is entirely speculative. Indeed, a range of studies show that the opposite is likely true. 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.

Consider a few examples from the empirical literature:

  1. Li and Agarwal (2017) find that Facebook’s integration of Instagram led to a significant increase in user demand both for Instagram itself and for the entire category of photography apps. Instagram’s integration with Facebook increased consumer awareness of photography apps, which benefited independent developers, as well as Facebook.
  2. Foerderer, et al. (2018) find that Google’s 2015 entry into the market for photography apps on Android created additional user attention and demand for such apps generally.
  3. Cennamo, et al. (2018) find that video games offered by console firms often become blockbusters and expand the consoles’ installed base. As a result, these games increase the potential for all independent game developers to profit from their games, even in the face of competition from first-party games.
  4. Finally, while Zhu and Liu (2018) is often held up as demonstrating harm from Amazon’s competition with third-party sellers on its platform, its findings are actually far from clear-cut. As co-author Feng Zhu noted in the Journal of Economics & Management Strategy: “[I]f Amazon’s entries attract more consumers, the expanded customer base could incentivize more third‐ party sellers to join the platform. As a result, the long-term effects for consumers of Amazon’s entry are not clear.”

2. Interoperability Is Not Costless

There are many things that could be interoperable, but aren’t. The reason not everything is interoperable 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.

As Sam Bowman has observed, there are often 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 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.

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

3. Consumers Often Prefer Closed Ecosystems

Digital markets could have taken a vast number of shapes. So why have they gravitated toward the very characteristics that authorities condemn? For instance, if market tipping and consumer lock-in are so problematic, why is it that new corners of the digital economy continue to emerge via closed platforms, as opposed to collaborative ones?

Indeed, if recent commentary is to be believed, it is the latter that should succeed, because they purportedly produce greater gains from trade. And if consumers and platforms cannot realize these gains by themselves, then we should see intermediaries step into that breach. But this does not seem to be happening in the digital economy.

The naïve answer is to say that the absence of “open” systems is precisely the problem. What’s harder is to try to actually understand why. As I have written, there are many reasons that consumers might prefer “closed” systems, even when they have to pay a premium for them.

Take the example of app stores. Maintaining some control over the apps that can access the store notably enables platforms to easily weed out bad players. Similarly, controlling the hardware resources that each app can use may greatly improve device performance. In other words, centralized platforms can eliminate negative externalities that “bad” apps impose on rival apps and on consumers. This is especially true when consumers struggle to attribute dips in performance to an individual app, rather than the overall platform.

It is also conceivable that consumers prefer to make many of their decisions at the inter-platform level, rather than within each platform. In simple terms, users arguably make their most important decision when they choose between an Apple or Android smartphone (or a Mac and a PC, etc.). In doing so, they can select their preferred app suite with one simple decision.

They might thus purchase an iPhone because they like the secure App Store, or an Android smartphone because they like the Chrome Browser and Google Search. Forcing too many “within-platform” choices upon users may undermine a product’s attractiveness. Indeed, it is difficult to create a high-quality reputation if each user’s experience is fundamentally different. In short, contrary to what antitrust authorities seem to believe, closed platforms might be giving most users exactly what they desire.

Too often, it is simply assumed that consumers benefit from more openness, and that shared/open platforms are the natural order of things. What some refer to as “market failures” may in fact be features that explain the rapid emergence of the digital economy. Ronald Coase said it best when he quipped that economists always find a monopoly explanation for things that they simply fail to understand.

4. Data Portability Can Undermine Security and Privacy

As explained above, platforms that are more tightly controlled can be regulated by the platform owner to avoid some of the risks present in more open platforms. Apple’s App Store, for example, is a relatively closed and curated platform, which gives users assurance that apps will meet a certain standard of security and trustworthiness.

Along similar lines, there are privacy issues that arise from data portability. Even a relatively simple requirement to make photos available for download can implicate third-party interests. Making a user’s photos more broadly available may tread upon the privacy interests of friends whose faces appear in those photos. Importing those photos to a new service potentially subjects those individuals to increased and un-bargained-for security risks.

As Sam Bowman and Geoff Manne observe, this is exactly what happened with Facebook and its Social Graph API v1.0, ultimately culminating in the Cambridge Analytica scandal. Because v1.0 of Facebook’s Social Graph API permitted developers to access information about a user’s friends without consent, it enabled third-party access to data about exponentially more users. It appears that some 270,000 users granted data access to Cambridge Analytica, from which the company was able to obtain information on 50 million Facebook users.

In short, there is often no simple solution to implement interoperability and data portability. Any such program—whether legally mandated or voluntarily adopted—will need to grapple with these and other tradeoffs.

5. Network Effects Are Rarely Insurmountable

Several scholars in recent years have called for more muscular antitrust intervention in networked industries on grounds that network externalities, switching costs, and data-related increasing returns to scale lead to inefficient consumer lock-in and raise entry barriers for potential rivals (see here, here, and here). But there are 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 wrote in April 2019 (a year before the COVID-19 pandemic):

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.

Geoff Manne and Alec Stapp have put forward a multitude of other examples,  including: the demise of Yahoo; the disruption of early instant-messaging applications and websites; and MySpace’s rapid decline. In all of these cases, outcomes did 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 powerful algorithm are the most likely explanations for its success.

While these developments certainly do not disprove network-effects theory, they eviscerate the belief, common in antitrust circles, that superior rivals are unable to overthrow incumbents in digital markets. Of course, this will not always be the case. 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.

6. Profits Facilitate New and Exciting Platforms

As I wrote in August 2020, the relatively closed model employed by several successful platforms (notably Apple’s App Store, Google’s Play Store, and the Amazon Retail Platform) allows previously unknown developers/retailers to rapidly expand because (i) users do not have to fear their apps contain some form of malware and (ii) they greatly reduce payments frictions, most notably security-related ones.

While these are, indeed, tremendous benefits, another important upside seems to have gone relatively unnoticed. The “closed” business model also gives firms significant incentives to develop new distribution mediums (smart TVs spring to mind) and to improve existing ones. In turn, this greatly expands the audience that software developers can reach. In short, developers get a smaller share of a much larger pie.

The economics of two-sided markets are enlightening here. For example, Apple and Google’s app stores are what Armstrong and Wright (here and here) refer to as “competitive bottlenecks.” That is, they compete aggressively (among themselves, and with other gaming platforms) to attract exclusive users. They can then charge developers a premium to access those users.

This dynamic gives firms significant incentive to continue to attract and retain new users. For instance, if Steve Jobs is to be believed, giving consumers better access to media such as eBooks, video, and games was one of the driving forces behind the launch of the iPad.

This model of innovation would be seriously undermined if developers and consumers could easily bypass platforms, as would likely be the case under the American Innovation and Choice Online Act.

7. Large Market Share Does Not Mean Anticompetitive Outcomes

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. Indeed, as economists like Joseph Bertrand and William Baumol have shown, what matters is not whether markets are concentrated, but whether they are contestable. If a superior rival could rapidly gain user traction, that alone will discipline incumbents’ behavior.

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

Unfortunately, critics’ failure to meaningfully grapple with these issues serves to shape the “conventional wisdom” in tech-policy debates.

8. Vertical Integration Generally Benefits Consumers

Vertical behavior of digital firms—whether through mergers or through contract and unilateral action—frequently arouses the ire of critics of the current antitrust regime. Many such critics point to a few recent studies that cast doubt on the ubiquity of benefits from vertical integration. But the findings of these few studies are regularly overstated and, even if taken at face value, represent a just minuscule fraction of the collected evidence, which overwhelmingly supports vertical integration.

There is strong and longstanding empirical evidence that vertical integration is competitively benign. This includes widely acclaimed work by economists Francine Lafontaine (former director of the Federal Trade Commission’s Bureau of Economics under President Barack Obama) and Margaret Slade, whose meta-analysis led them to conclude:

[U]nder most circumstances, profit-maximizing vertical integration decisions are efficient, not just from the firms’ but also from the consumers’ points of view. Although there are isolated studies that contradict this claim, the vast majority support it. Moreover, even in industries that are highly concentrated so that horizontal considerations assume substantial importance, the net effect of vertical integration appears to be positive in many instances. We therefore conclude that, faced with a vertical arrangement, the burden of evidence should be placed on competition authorities to demonstrate that that arrangement is harmful before the practice is attacked.

In short, there is a substantial body of both empirical and theoretical research showing that vertical integration (and the potential vertical discrimination and exclusion to which it might give rise) is generally beneficial to consumers. While it is possible that vertical mergers or discrimination could sometimes cause harm, the onus is on the critics to demonstrate empirically where this occurs. No legitimate interpretation of the available literature would offer a basis for imposing a presumption against such behavior.

9. There Is No Such Thing as Data Network Effects

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 was shown by the survey pf the empirical literature that Geoff Manne and I performed (published in the George Mason Law Review), data generally entails diminishing marginal returns:

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. Indeed, Facebook managed to build a highly successful platform despite a large data disadvantage when compared to rivals like MySpace.

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.

10.  Antitrust Enforcement Has Not Been Lax

The popular narrative has it that lax antitrust enforcement has led to substantially increased concentration, strangling the economy, harming workers, and expanding dominant firms’ profit margins at the expense of consumers. Much of the contemporary dissatisfaction with antitrust arises from a suspicion that overly lax enforcement of existing laws has led to record levels of concentration and a concomitant decline in competition. But both beliefs—lax enforcement and increased anticompetitive concentration—wither under more than cursory scrutiny.

As Geoff Manne observed in his April 2020 testimony to the House Judiciary Committee:

The number of Sherman Act cases brought by the federal antitrust agencies, meanwhile, has been relatively stable in recent years, but several recent blockbuster cases have been brought by the agencies and private litigants, and there has been no shortage of federal and state investigations. The vast majority of Section 2 cases dismissed on the basis of the plaintiff’s failure to show anticompetitive effect were brought by private plaintiffs pursuing treble damages; given the incentives to bring weak cases, it cannot be inferred from such outcomes that antitrust law is ineffective. But, in any case, it is highly misleading to count the number of antitrust cases and, using that number alone, to make conclusions about how effective antitrust law is. Firms act in the shadow of the law, and deploy significant legal resources to make sure they avoid activity that would lead to enforcement actions. Thus, any given number of cases brought could be just as consistent with a well-functioning enforcement regime as with an ill-functioning one.

The upshot is that naïvely counting antitrust cases (or the purported lack thereof), with little regard for the behavior that is deterred or the merits of the cases that are dismissed does not tell us whether or not antitrust enforcement levels are optimal.

Shorter pieces

Early last month, the Italian competition authority issued a record 1.128 billion euro fine against Amazon for abuse of dominance under Article 102 of the Treaty on the Functioning of the European Union (TFEU). In its order, the Agenzia Garante della Concorrenza e del Mercato (AGCM) essentially argues that Amazon has combined its Amazon.it marketplace and Fulfillment by Amazon (FBA) services to exclude logistics rivals such as FedEx, DHL, UPS, and Poste Italiane. 

The sanctions came exactly one month after the European General Court seconded the European Commission’s “discovery” in the Google Shopping case of a new antitrust infringement known as “self-preferencing,” which also cited Article 102 TFEU. Perhaps not entirely coincidentally, legislation was introduced in the United States earlier this year to prohibit the practice. Meanwhile, the EU’s legislative bodies have been busy taking steps to approve the Digital Markets Act (DMA), which would regulate so-called digital “gatekeepers.”

Italy thus joins a wave of policymakers that have either imposed heavy-handed decisions to “rein in” online platforms, or are seeking to implement ex ante regulations toward that end. Ultimately, the decision is reminiscent of the self-preferencing prohibition contained in Article 6a of the current draft of the DMA and reflects much of what is wrong with the current approach to regulating tech. It presages some of the potential problems with punishing efficient behavior for the sake of protecting competitors through “common carrier antitrust.” However, if this decision is anything to go by, these efforts will end up hurting the very consumers authorities purport to protect and lending color to more general fears over the DMA. 

In this post, we discuss how the AGCM’s reasoning departs from sound legal and economic thinking to reach a conclusion at odds with the traditional goal of competition law—i.e., the protection of consumer welfare. Neo-Brandeisians and other competition scholars who dispute the centrality of the consumer welfare standard and would use antitrust to curb “bigness” may find this result acceptable, in principle. But even they must admit that the AGCM decision ultimately serves to benefit large (if less successful) competitors, and not the “small dealers and worthy men” of progressive lore.

Relevant Market Definition

Market definition constitutes a preliminary step in any finding of abuse under Article 102 TFEU. An excessively narrow market definition can result in false positives by treating neutral or efficient conduct as anticompetitive, while an overly broad market definition might allow anticompetitive conduct to slip through the cracks, leading to false negatives. 

Amazon Italy may be an example of the former. Here, the AGCM identified two relevant markets: the leveraging market, which it identified as the Italian market for online marketplace intermediation, and the leveraged market, which it identified as the market for e-commerce logistics. The AGCM charges that Amazon is dominant in the former and that it gained an illegal advantage in the latter. It found, in this sense, that online marketplaces constitute a uniquely relevant market that is not substitutable for other offline or online sales channels, such as brick-and-mortar shops, price-comparison websites (e.g., Google Shopping), or dedicated sales websites (e.g., Nike.com/it). Similarly, it concluded that e-commerce logistics are sufficiently different from other forms of logistics as to comprise a separate market.

The AGCM’s findings combine qualitative and quantitative evidence, including retailer surveys and “small but significant and non-transitory increase in price” (SSNIP) tests. They also include a large dose of speculative reasoning.

For instance, the AGCM asserts that online marketplaces are fundamentally different from price-comparison sites because, in the latter case, purchase transactions do not take place on the platform. It asserts that e-commerce logistics are different from traditional logistics because the former require a higher degree of automation for transportation and storage. And in what can only be seen as a normative claim, rather than an objective assessment of substitutability, the Italian watchdog found that marketplaces are simply better than dedicated websites because, e.g., they offer greater visibility and allow retailers to save on marketing costs. While it is unclear what weights the AGCM assigned to each of these considerations when defining the relevant markets, it is reasonable to assume they played some part in defining the nature and scope of Amazon’s market presence in Italy.

In all of these instances, however, while the AGCM carefully delineated superficial distinctions between these markets, it did not actually establish that those differences are relevant to competition. Fetishizing granular but ultimately irrelevant differences between products and services—such as between marketplaces and shopping comparison sites—is a sure way to incur false positives, a misstep tantamount to punishing innocuous or efficient business conduct.

Dominance

The AGCM found that Amazon was “hyper-dominant” in the online marketplace intermediation market. Dominance was established by looking at revenue from marketplace sales, where Amazon’s share had risen from about 65% in 2016 to 75% in 2019. Taken in isolation, this figure might suggest that Amazon’s competitors cannot thrive in the market. A broader look at the data, however, paints a picture of more generalized growth, with some segments greatly benefiting newcomers and small, innovative marketplaces. 

For instance, virtually all companies active in the online marketplace intermediation market have experienced significant growth in terms of monthly visitors. It is true that Amazon’s visitors grew significantly, up 150%, but established competitors like Aliexpress and eBay also saw growth rates of 90% and 25%, respectively. Meanwhile, Wish grew a massive 10,000% from 2016 to 2019; while ManoMano and Zalando grew 450% and 100%, respectively.

In terms of active users (i.e., visits that result in a purchase), relative numbers seem to have stayed roughly the same, although the AGCM claims that eBay saw a 20-30% drop. The number of third-party products Amazon offered through Marketplace grew from between 100 and 500 million to between 500 million and 1 billion, while other marketplaces appear to have remained fairly constant, with some expanding and others contracting.

In sum, while Amazon has undeniably improved its position in practically all of the parameters considered by the AGCM, indicators show that the market as a whole has experienced and is experiencing growth. The improvement in Amazon’s position relative to some competitors—notably eBay, which AGCM asserts is Amazon’s biggest competitor—should therefore not obscure the fact that there is entry and expansion both at the fringes (ManoMano, Wish), and in the center of the market for online marketplace intermediation (Aliexpress).

Amazon’s Allegedly Abusive Conduct

According to the AGCM, Amazon has taken advantage of vertical integration to engage in self-preferencing. Specifically, the charge is that the company offers exclusive and purportedly crucial advantages on the Amazon.it marketplace to sellers who use Amazon’s own e-commerce logistics service, FBA. The purported advantages of this arrangement include, to name a few, the coveted Prime badge, the elimination of negative user feedback on sale or delivery, preferential algorithmic treatment, and exclusive participation in Amazon’s sales promotions (e.g., Black Friday, Cyber Monday). As a result, according to the AGCM, products sold through FBA enjoy more visibility and a better chance to win the “Buy Box.”

The AGCM claims this puts competing logistics operators like FedEx, Poste Italiane, and DHL at a disadvantage, because non-FBA products have less chance to be sold than FBA products, regardless of any efficiency or quality criteria. In the AGCM’s words, “Amazon has stolen demand for other e-commerce logistics operators.” 

Indirectly, Amazon’s “self-preferencing” purportedly also harms competing marketplaces like eBay by creating incentives for sellers to single-home—i.e., to sell only through Amazon Marketplace. The argument here is that retailers will not multi-home to avoid duplicative costs associated with FBA, e.g., storing goods in several warehouses. 

Although it is not necessary to demonstrate anticompetitive effects under Article 102 TFEU, the AGCM claims that Amazon’s behavior has caused drastic worsening in other marketplaces’ competitive position by constraining their ability to reach the minimum scale needed to enjoy direct and indirect network effects. The Italian authorities summarily assert that this results in consumer harm, although the gargantuan 250-page decision spends scarcely one paragraph on this point. 

Intuitively, however, Amazon’s behavior should, in principle, benefit consumers by offering something that most find tremendously valuable: a guarantee of quick delivery for a wide range of goods. Indeed, this is precisely why it is so misguided to condemn self-preferencing by online platforms.

As some have already argued, we cannot assume that something is bad for competition just because it is bad for certain competitors. For instance, a lot of unambiguously procompetitive behavior, like cutting prices, puts competitors at a disadvantage. The same might be true for a digital platform that preferences its own service because it is generally better than the alternatives provided by third-party sellers. In the case at hand, for example, Amazon’s granting marketplace privileges to FBA products may help users to select the products that Amazon can guarantee will best satisfy their needs. This is perfectly plausible, as customers have repeatedly shown that they often prefer less open, less neutral options.

The key question, therefore, should be whether the behavior in question excludes equally efficient rivals in such a way as to harm consumer welfare. Otherwise, we would essentially be asking companies to refrain from offering services that benefit their users in order to make competing products comparatively more attractive. This is antithetical to the nature of competition, which is based on the principle that what is good for consumers is frequently bad for competitors.

AGCM’s Theory of Harm Rests on Four Weak Pillars

Building on the logic that Amazon enjoys “hyper-dominance” in marketplace intermediation; that most online sales are marketplace sales; and that most marketplace sales are, in turn, Amazon.it sales, the AGCM decision finds that succeeding on Amazon.it is indispensable for any online retailer in Italy. This argument hinges largely on whether online and offline retailers are thought of as distinct relevant markets—i.e., whether, from the perspective of the retailer, online and offline sales channels are substitutable (see also the relevant market definition section above). 

Ultimately, the AGCM finds that they are not, as online sales enjoy such advantages as lower fixed costs, increased sale flexibility, and better geographical reach. To an outsider, the distinction between the two markets may seem artificial—and it largely is—but such theoretical market segmentation is the bread-and-butter of antitrust analysis. Still, even by EU competition law standards, the relevant market definitions on which the AGCM relies to conclude that selling on Amazon is indispensable appear excessively narrow. 

This market distinction also serves to set up the AGCM’s second, more controversial argument: that the benefits extended to products sold through the FBA channel are also indispensable for retailers’ success on the Amazon.it marketplace. Here, the AGCM seeks a middle ground between competitive advantage and indispensability, finally settling on the notion that a sufficiently large competitive advantage itself translates into indispensability.

But how big is too big? The facts that 40-45% of Amazon’s third-party retailers do not use FBA (p. 57 of the decision) and that roughly 40 of the top 100 products sold on Amazon.it are not fulfilled through Amazon’s logistics service (p. 58) would appear to suggest that FBA is more of a convenience than an obligation. At the least, it does not appear that the advantage conferred is so big as to amount to indispensability. This may be because sellers that choose not to use Amazon’s logistics service (including offline, of course) can and do cut prices to compete with FBA-sold products. If anything, this should be counted as a good thing from the perspective of consumer welfare.

Instead, and signaling the decision’s overarching preoccupation with protecting some businesses at the expense of others (and, ultimately, at the expense of consumers), the AGCM has expanded the already bloated notion of a self-preferencing offense to conclude that expecting sellers to compete on pricing parameters would unfairly slash profit margins for non-FBA sellers.

The third pillar of the AGCM’s theory of harm is the claim that the benefits conferred on products sold through FBA are not awarded based on any objective quality criteria, but purely on whether the seller has chosen FBA or third-party logistics. Thus, even if a logistics operator were, in principle, capable of offering a service as efficient as FBA’s, it would not qualify for the same benefits. 

But this is a disingenuous line of reasoning. One legitimate reason why Amazon could choose to confer exclusive advantages on products fulfilled by its own logistics operation is because no other service is, in fact, routinely as reliable. This does not necessarily mean that FBA is always superior to the alternatives, but rather that it makes sense for Amazon to adopt this presumption a general rule based on past experience, without spending the resources to constantly evaluate it. In other words, granting exclusive benefits is based on quality criteria, just on a prior measurement of quality rather than an ongoing assessment. This is presumably what a customer-obsessed business that does not want to take chances with consumer satisfaction would do. 

Fourth, the AGCM posits that Prime and FBA constitute two separate products that have been artificially tied by Amazon, thereby unfairly excluding third-party logistics operators. Co-opting Amazon’s own terminology, the AGCM claims that the company has created a flywheel of artificial interdependence, wherein Prime benefits increase the number of Prime users, which drives demand for Prime products, which creates demand for Prime-eligible FBA products, and so on. 

To support its case, the AGCM repeatedly adduces a 2015 letter in which Jeff Bezos told shareholders that Amazon Marketplace and Prime are “happily and deeply intertwined,” and that FBA is the “glue” that links them together. Instead of taking this for what it likely is—i.e., a case of legitimate, efficiency-enhancing vertical integration—the AGCM has preferred to read into it a case of illicit tying, an established offense under Article 102 TFEU whereby a dominant firm makes the purchase of one product conditional on the purchase of another, unrelated one. 

The problem with this narrative is that it is perfectly plausible that Prime and FBA are, in fact, meant to be one product that is more than the sum of its parts. For one, the inventory of sellers who use FBA is stowed in fulfillment centers, meaning that Amazon takes care of all logistics, customer service, and product returns. As Bezos put it in the same 2015 letter, this is a huge efficiency gain. It thus makes sense to nudge consumers towards products that use FBA.

In sum, the AGCM’s case rests on a series of questionable assumptions that build on each other: a narrow relevant market definition; a finding of “hyper-dominance” that downplays competitors’ growth and expansion, as well as competition from outside the narrowly defined market; a contrived notion of indispensability at two levels (Marketplace and FBA); and a refusal to contemplate the possibility that Amazon integrates its marketplace and logistics services in orders to enhance efficiency, rather than to exclude competitors.

Remedies

The AGCM sees “only one way to restore a level-playing field in e-commerce logistics”: Amazon must redesign its existing Self-Fulfilled Prime (SFP) program in such a way as to grant all logistics operators—FBA or non-FBA—equal treatment on Amazon.it, based on a set of objective, transparent, standard, uniform, and non-discriminatory criteria. Any logistics operator that demonstrates the ability to fulfill such criteria must be awarded SFP status and the accompanying Prime badge, along with all the perks associated with it. Further, SFP- and FBA-sold products must be subject to the same monitoring mechanism with regard to the observance of Prime standards, as well as to the same evaluation standards. 

In sum, Amazon Italy now has a duty to treat Marketplace sales fulfilled by third-party operators the same as those fulfilled by its own logistics service. This is a significant step toward “common carrier antitrust.” in which vertically integrated firms are expected to comply with perfect neutrality obligations with respect to customers, suppliers, and competitors

Beyond the philosophical question of whether successful private companies should be obliged by law to treat competitors analogously to its affiliates (they shouldn’t), the pitfalls of this approach are plain to see. Nearly all consumer-facing services use choice architectures as a means to highlight products that rank favorably in terms of price and quality, and ensuring consumers enjoy a seamless user experience: Supermarkets offer house brands that signal a product has certain desirable features; operating system developers pre-install certain applications to streamline users’ “out of the box “experience; app stores curate the apps that users will view; search engines use specialized boxes that anticipate the motives underlying users’ search queries, etc. Suppressing these practices through heavy-handed neutrality mandates is liable to harm consumers. 

Second, monitoring third-party logistics operators’ compliance with the requisite standards is going to come at a cost for Amazon (and, presumably, its customers)—a cost likely much higher than that of monitoring its own operations—while awarding the Prime badge liberally may deteriorate the consumer experience on Amazon Marketplace.

Thus, one way for Amazon to comply with AGCM’s remedies while also minimizing monitoring costs is simply to dilute or even remove the criteria for Prime, thereby allowing sellers using any logistics provider to be eligible for Prime. While this would presumably insulate Amazon from any future claims against exclusionary self-preferencing, it would almost certainly also harm consumer welfare. 

A final point worth noting is that vertical integration may well be subsidizing Amazon’s own first-party products. In other words, even if FBA is not fully better than other logistics operators, the revenue that it derives from FBA enables Amazon to offer low prices, as well as a range of other benefits from Prime, such as, e.g., free video. Take that source of revenue away, and those subsidized prices go up and the benefits disappear. This is another reason why it may be legitimate to consider FBA and Prime as a single product.

Of course, this argument is moot if all one cares about is how Amazon’s vertical integration affects competitors, not consumers. But consumers care about the whole package. The rationale at play in the AGCM decision ultimately ends up imposing a narrow, boring business model on all sellers, precluding them from offering interesting consumer benefits to bolster their overall product.

Conclusion

Some have openly applauded AGCM’s use of EU competition law to protect traditional logistics operators like FedEx, Poste Italiane, DHL, and UPS. Others lament the competition authority’s apparent abandonment of the consumer welfare standard in favor of a renewed interest in punishing efficiency to favor laggard competitors under the guise of safekeeping “competition.” Both sides ultimately agree on one thing, however: Amazon Italy is about favoring Amazon’s competitors. If competition authorities insist on continuing down this populist rabbit hole,  the best they can hope for is a series of Pyrrhic victories against the businesses that are most bent on customer satisfaction, i.e., the successful ones.

Some may intuitively think that this is fair; that Amazon is just too big and that it strangles small competitors. But Amazon’s “small” competitors are hardly the “worthy men” of Brandeisian mythology. They are FedEx, DHL, UPS, and the state-backed goliath Poste Italiane; they are undeniably successful companies like eBay, Alibaba – or Walmart in the United States. It is, conversely, the smallest retailers and consumers who benefit the most from Amazon’s integrated logistics and marketplace services, as the company’s meteoric rise in popularity in Italy since 2016 attests. But it seems that, in the brave new world of antitrust, such stakeholders are now too small to matter.

Even as delivery services work to ship all of those last-minute Christmas presents that consumers bought this season from digital platforms and other e-commerce sites, the U.S. House and Senate are contemplating Grinch-like legislation that looks to stop or limit how Big Tech companies can “self-preference” or “discriminate” on their platforms.

A platform “self-preferences” when it blends various services into the delivery of a given product in ways that third parties couldn’t do themselves. For example, Google self-preferences when it puts a Google Shopping box at the top of a Search page for Adidas sneakers. Amazon self-preferences when it offers its own AmazonBasics USB cables alongside those offered by Apple or Anker. Costco’s placement of its own Kirkland brand of paper towels on store shelves can also be a form of self-preferencing.

Such purportedly “discriminatory” behavior constitutes much of what platforms are designed to do. Virtually every platform that offers a suite of products and services will combine them in ways that users find helpful, even if competitors find it infuriating. It surely doesn’t help Yelp if Google Search users can see a Maps results box next to a search for showtimes at a local cinema. It doesn’t help other manufacturers of charging cables if Amazon sells a cheaper version under a brand that consumers trust. But do consumers really care about Yelp or Apple’s revenues, when all they want are relevant search results and less expensive products?

Until now, competition authorities have judged this type of conduct under the consumer welfare standard: does it hurt consumers in the long run, or does it help them? This test does seek to evaluate whether the conduct deprives consumers of choice by foreclosing rivals, which could ultimately allow the platform to exploit its customers. But it doesn’t treat harm to competitors—in the form of reduced traffic and profits for Yelp, for example—as a problem in and of itself.

“Non-discrimination” bills introduced this year in both the House and Senate aim to change that, but they would do so in ways that differ in important respects.

The House bill would impose a blanket ban on virtually all “discrimination” by platforms. This means that even such benign behavior as Facebook linking to Facebook Marketplace on its homepage would become presumptively unlawful. The measure would, as I’ve written before, break a lot of the Internet as we know it, but it has the virtue of being explicit and clear about its effects.

The Senate bill is, in this sense, a lot more circumspect. Instead of a blanket ban, it would prohibit what the bill refers to as “unfair” discrimination that “materially harm[s] competition on the covered platform,” with a carve-out exception for discrimination that was “necessary” to maintain or enhance the “core functionality” of the platform. In theory, this would avoid a lot of the really crazy effects of the House bill. Apple likely still could, for example, pre-install a Camera app on the iPhone.

But this greater degree of reasonableness comes at the price of ambiguity. The bill does not define “unfair discrimination,” nor what it would mean for something to be “necessary” to improve the core functionality of a platform. Faced with this ambiguity, companies would be wise to be overly cautious, given the steep penalties they would face for conduct found to be “unfair”: 15% of total U.S. revenues earned during the period when the conduct was ongoing. That’s a lot of money to risk over a single feature!

Also unlike the House legislation, the Senate bill would not create a private right of action, thereby limiting litigation to enforce the bill’s terms to actions brought by the Federal Trade Commission (FTC), U.S. Justice Department (DOJ), or state attorneys general.

Put together, these features create the perfect recipe for extensive discretionary power held by a handful of agencies. With such vague criteria and such massive penalties for lawbreaking, the mere threat of a lawsuit could force a company to change its behavior. The rules are so murky that companies might even be threatened with a lawsuit over conduct in one area in order to make them change their behavior in another.

It’s hardly unprecedented for powers like this to be misused. During the Obama administration, the Internal Revenue Service (IRS) was alleged to have targeted conservative groups for investigation, for which the agency eventually had to apologize (and settle a lawsuit brought by some of the targeted groups). More than a decade ago, the Bank Secrecy Act was used to uncover then-New York Attorney General Eliot Spitzer’s involvement in an international prostitution ring. Back in 2008, the British government used anti-terrorism powers to seize the assets of some Icelandic banks that had become insolvent and couldn’t repay their British depositors. To this day, municipal governments in Britain use anti-terrorism powers to investigate things like illegal waste dumping and people who wrongly park in spots reserved for the disabled.

The FTC itself has a history of abusing its authority. As Commissioners Noah Phillips and Christine Wilson remind us, the commission was nearly shut down in the 1970s after trying to use its powers to “protect” children from seeing ads for sugary foods, interpreting its consumer-protection mandate so broadly that it considered tooth decay as falling within its scope.

As I’ve written before, both Chair Lina Khan and Commissioner Rebecca Kelly Slaughter appear to believe that the FTC ought to take a broad vision of its goals. Slaughter has argued that antitrust ought to be “antiracist.” Khan believes that the “the dispersion of political and economic control” is the proper goal of antitrust, not consumer welfare or some other economic goal.

Khan in particular does not appear especially bound by the usual norms that might constrain this sort of regulatory overreach. In recent weeks, she has pushed through contentious decisions by relying on more than 20 “zombie votes” cast by former Commissioner Rohit Chopra on the final day before he left the agency. While it has been FTC policy since 1984 to count votes cast by departed commissioners unless they are superseded by their successors, Khan’s FTC has invoked this relatively obscure rule to swing more decisions than every single predecessor combined.

Thus, while the Senate bill may avoid immediately breaking large portions of the Internet in ways the House bill would, it would instead place massive discretionary powers into the hands of authorities who have expansive views about the goals those powers ought to be used to pursue.

This ought to be concerning to anyone who disapproves of public policy being made by unelected bureaucrats, rather than the people’s chosen representatives. If Republicans find an empowered Khan-led FTC worrying today, surely Democrats ought to feel the same about an FTC run by Trump-style appointees in a few years. Both sides may come to regret creating an agency with so much unchecked power.

Others already have noted that the Federal Trade Commission’s (FTC) recently released 6(b) report on the privacy practices of Internet service providers (ISPs) fails to comprehend that widespread adoption of privacy-enabling technology—in particular, Hypertext Transfer Protocol Secure (HTTPS) and DNS over HTTPS (DoH), but also the use of virtual private networks (VPNs)—largely precludes ISPs from seeing what their customers do online.

But a more fundamental problem with the report lies in its underlying assumption that targeted advertising is inherently nefarious. Indeed, much of the report highlights not actual violations of the law by the ISPs, but “concerns” that they could use customer data for targeted advertising much like Google and Facebook already do. The final subheading before the report’s conclusion declares: “Many ISPs in Our Study Can Be At Least As Privacy-Intrusive as Large Advertising Platforms.”

The report does not elaborate on why it would be bad for ISPs to enter the targeted advertising market, which is particularly strange given the public focus regulators have shone in recent months on the supposed dominance of Google, Facebook, and Amazon in online advertising. As the International Center for Law & Economics (ICLE) has argued in past filings on the issue, there simply is no justification to apply sector-specific regulations to ISPs for the mere possibility that they will use customer data for targeted advertising.

ISPs Could be Competition for the Digital Advertising Market

It is ironic to witness FTC warnings about ISPs engaging in targeted advertising even as there are open antitrust cases against Google for its alleged dominance of the digital advertising market. In fact, news reports suggest the U.S. Justice Department (DOJ) is preparing to join the antitrust suits against Google brought by state attorneys general. An obvious upshot of ISPs engaging in a larger amount of targeted advertising if that they could serve as a potential source of competition for Google, Facebook, and Amazon.

Despite the fears raised in the 6(b) report of rampant data collection for targeted ads, ISPs are, in fact, just a very small part of the $152.7 billion U.S. digital advertising market. As the report itself notes: “in 2020, the three largest players, Google, Facebook, and Amazon, received almost two-third of all U.S. digital advertising,” while Verizon pulled in just 3.4% of U.S. digital advertising revenues in 2018.

If the 6(b) report is correct that ISPs have access to troves of consumer data, it raises the question of why they don’t enjoy a bigger share of the digital advertising market. It could be that ISPs have other reasons not to engage in extensive advertising. Internet service provision is a two-sided market. ISPs could (and, over the years in various markets, some have) rely on advertising to subsidize Internet access. That they instead rely primarily on charging users directly for subscriptions may tell us something about prevailing demand on either side of the market.

Regardless of the reasons, the fact that ISPs have little presence in digital advertising suggests that it would be a misplaced focus for regulators to pursue industry-specific privacy regulation to crack down on ISP data collection for targeted advertising.

What’s the Harm in Targeted Advertising, Anyway?

At the heart of the FTC report is the commission’s contention that “advertising-driven surveillance of consumers’ online activity presents serious risks to the privacy of consumer data.” In Part V.B of the report, five of the six risks the FTC lists as associated with ISP data collection are related to advertising. But the only argument the report puts forth for why targeted advertising would be inherently pernicious is the assertion that it is contrary to user expectations and preferences.

As noted earlier, in a two-sided market, targeted ads could allow one side of the market to subsidize the other side. In other words, ISPs could engage in targeted advertising in order to reduce the price of access to consumers on the other side of the market. This is, indeed, one of the dominant models throughout the Internet ecosystem, so it wouldn’t be terribly unusual.

Taking away ISPs’ ability to engage in targeted advertising—particularly if it is paired with rumored net neutrality regulations from the Federal Communications Commission (FCC)—would necessarily put upward pricing pressure on the sector’s remaining revenue stream: subscriber fees. With bridging the so-called “digital divide” (i.e., building out broadband to rural and other unserved and underserved markets) a major focus of the recently enacted infrastructure spending package, it would be counterproductive to simultaneously take steps that would make Internet access more expensive and less accessible.

Even if the FTC were right that data collection for targeted advertising poses the risk of consumer harm, the report fails to justify why a regulatory scheme should apply solely to ISPs when they are such a small part of the digital advertising marketplace. Sector-specific regulation only makes sense if the FTC believes that ISPs are uniquely opaque among data collectors with respect to their collection practices.

Conclusion

The sector-specific approach implicitly endorsed by the 6(b) report would limit competition in the digital advertising market, even as there are already legal and regulatory inquiries into whether that market is sufficiently competitive. The report also fails to make the case the data collection for target advertising is inherently bad, or uniquely bad when done by an ISP.

There may or may not be cause for comprehensive federal privacy legislation, depending on whether it would pass cost-benefit analysis, but there is no reason to focus on ISPs alone. The FTC needs to go back to the drawing board.

[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.

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.

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.

Digital advertising is the economic backbone of the Internet. It allows websites and apps to monetize their userbase without having to charge them fees, while the emergence of targeted ads allows this to be accomplished affordably and with less wasted time wasted.

This advertising is facilitated by intermediaries using the “adtech stack,” through which advertisers and publishers are matched via auctions and ads ultimately are served to relevant users. This intermediation process has advanced enormously over the past three decades. Some now allege, however, that this market is being monopolized by its largest participant: Google.

A lawsuit filed by the State of Texas and nine other states in December 2020 alleges, among other things, that Google has engaged in anticompetitive conduct related to its online display advertising business. Those 10 original state plaintiffs were joined by another four states and the Commonwealth of Puerto Rico in March 2021, while South Carolina and Louisiana have also moved to be added as additional plaintiffs. Google also faces a pending antitrust lawsuit brought by the U.S. Justice Department (DOJ) and 14 states (originally 11) related to the company’s distribution agreements, as well as a separate action by the State of Utah, 35 other states, and the District of Columbia related to its search design.

In recent weeks, it has been reported that the DOJ may join the Texas suit or bring its own similar action against Google in the coming months. If it does, it should learn from the many misconceptions and errors in the Texas complaint that leave it on dubious legal and economic grounds.

​​Relevant market

The Texas complaint identifies at least five relevant markets within the adtech stack that it alleges Google either is currently monopolizing or is attempting to monopolize:

  1. Publisher ad servers;
  2. Display ad exchanges;
  3. Display ad networks;
  4. Ad-buying tools for large advertisers; and
  5. Ad-buying tools for small advertisers.

None of these constitute an economically relevant product market for antitrust purposes, since each “market” is defined according to how superficially similar the products are in function, not how substitutable they are. Nevertheless, the Texas complaint vaguely echoes how markets were conceived in the “Roadmap” for a case against Google’s advertising business, published last year by the Omidyar Network, which may ultimately influence any future DOJ complaint, as well.

The Omidyar Roadmap narrows the market from media advertising to digital advertising, then to the open supply of display ads, which comprises only 9% of the total advertising spending and less than 20% of digital advertising, as shown in the figure below. It then further narrows the defined market to the intermediation of the open supply of display ads. Once the market has been sufficiently narrowed, the Roadmap authors conclude that Google’s market share is “perhaps sufficient to confer market power.”

While whittling down the defined market may achieve the purposes of sketching a roadmap to prosecute Google, it also generates a mishmash of more than a dozen relevant markets for digital display and video advertising. In many of these, Google doesn’t have anything approaching market power, while, in some, Facebook is the most dominant player.

The Texas complaint adopts a non-economic approach to market definition.  It ignores potential substitutability between different kinds of advertising, both online and offline, which can serve as a competitive constraint on the display advertising market. The complaint considers neither alternative forms of display advertising, such as social media ads, nor alternative forms of advertising, such as search ads or non-digital ads—all of which can and do act as substitutes. It is possible, at the very least, that advertisers who choose to place ads on third-party websites may switch to other forms of advertising if the price of third-party website advertising was above competitive levels. To ignore this possibility, as the Texas complaint does, is to ignore the entire purpose of defining the relevant antitrust market altogether.

Offline advertising vs. online advertising

The fact that offline and online advertising employ distinct processes does not consign them to economically distinct markets. Indeed, online advertising has manifestly drawn advertisers from offline markets, just as previous technological innovations drew advertisers from other pre-existing channels.

Moreover, there is evidence that, in some cases, offline and online advertising are substitute products. For example, economists Avi Goldfarb and Catherine Tucker demonstrate that display advertising pricing is sensitive to the availability of offline alternatives. They conclude:

We believe our studies refute the hypothesis that online and offline advertising markets operate independently and suggest a default position of substitution. Online and offline advertising markets appear to be closely related. That said, it is important not to draw any firm conclusions based on historical behavior.

Display ads vs. search ads

There is perhaps even more reason to doubt that online display advertising constitutes a distinct, economically relevant market from online search advertising.

Although casual and ill-informed claims are often made to the contrary, various forms of targeted online advertising are significant competitors of each other. Bo Xing and Zhanxi Lin report firms spread their marketing budgets across these different sources of online marketing, and “search engine optimizers”—firms that help websites to maximize the likelihood of a valuable “top-of-list” organic search placement—attract significant revenue. That is, all of these different channels vie against each other for consumer attention and offer advertisers the ability to target their advertising based on data gleaned from consumers’ interactions with their platforms.

Facebook built a business on par with Google’s thanks in large part to advertising, by taking advantage of users’ more extended engagement with the platform to assess relevance and by enabling richer, more engaged advertising than previously appeared on Google Search. It’s an entirely different model from search, but one that has turned Facebook into a competitive ad platform.

And the market continues to shift. Somewhere between 37-56% of product searches start on Amazon, according to one survey, and advertisers have noticed. This is not surprising, given Amazon’s strong ability to match consumers with advertisements, and to do so when and where consumers are more likely to make a purchase.

‘Open’ display advertising vs. ‘owned-and-operated’ display advertising

The United Kingdom’s Competition and Markets Authority (like the Omidyar Roadmap report) has identified two distinct channels of display advertising, which they term “owned and operated” and “open.” The CMA concludes:

Over half of display expenditure is generated by Facebook, which owns both the Facebook platform and Instagram. YouTube has the second highest share of display advertising and is owned by Google. The open display market, in which advertisers buy inventory from many publishers of smaller scale (for example, newspapers and app providers) comprises around 32% of display expenditure.

The Texas complaint does not directly address the distinction between open and owned and operated, but it does allege anticompetitive conduct by Google with respect to YouTube in a separate “inline video advertising market.” 

The CMA finds that the owned-and-operated channel mostly comprises large social media platforms, which sell their own advertising inventory directly to advertisers or media agencies through self-service interfaces, such as Facebook Ads Manager or Snapchat Ads Manager.  In contrast, in the open display channel, publishers such as online newspapers and blogs sell their inventory to advertisers through a “complex chain of intermediaries.”  Through these, intermediaries run auctions that match advertisers’ ads to publisher inventory of ad space. In both channels, nearly all transactions are run through programmatic technology.

The CMA concludes that advertisers “largely see” the open and the owned-and-operated channels as substitutes. According to the CMA, an advertiser’s choice of one channel over the other is driven by each channel’s ability to meet the key performance metrics the advertising campaign is intended to achieve.

The Omidyar Roadmap argues, instead, that the CMA too narrowly focuses on the perspective of advertisers. The Roadmap authors claim that “most publishers” do not control supply that is “owned and operated.” As a result, they conclude that publishers “such as gardenandgun.com or hotels.com” do not have any owned-and-operated supply and can generate revenues from their supply “only through the Google-dominated adtech stack.” 

But this is simply not true. For example, in addition to inventory in its print media, Garden & Gun’s “Digital Media Kit” indicates that the publisher has several sources of owned-and-operated banner and video supply, including the desktop, mobile, and tablet ads on its website; a “homepage takeover” of its website; branded/sponsored content; its email newsletters; and its social media accounts. Hotels.com, an operating company of Expedia Group, has its own owned-and-operated search inventory, which it sells through its “Travel Ads Sponsored Listing,” as well owned-and-operated supply of standard and custom display ads.

Given that both perform the same function and employ similar mechanisms for matching inventory with advertisers, it is unsurprising that both advertisers and publishers appear to consider the owned-and-operated channel and the open channel to be substitutes.
