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.
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:
Publisher ad servers;
Display ad exchanges;
Display ad networks;
Ad-buying tools for large advertisers; and
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.
‘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.
The American Choice and Innovation Online Act (previously called the Platform Anti-Monopoly Act), introduced earlier this summer by U.S. Rep. David Cicilline (D-R.I.), would significantly change the nature of digital platforms and, with them, the internet itself. Taken together, the bill’s provisions would turn platforms into passive intermediaries, undermining many of the features that make them valuable to consumers. This seems likely to remain the case even after potential revisions intended to minimize the bill’s unintended consequences.
In its current form, the bill is split into two parts that each is dangerous in its own right. The first, Section 2(a), would prohibit almost any kind of “discrimination” by platforms. Because it is so open-ended, lawmakers might end up removing it in favor of the nominally more focused provisions of Section 2(b), which prohibit certain named conduct. But despite being more specific, this section of the bill is incredibly far-reaching and would effectively ban swaths of essential services.
Section 2(a) essentially prohibits any behavior by a covered platform that would advantage that platform’s services over any others that also uses that platform; it characterizes this preferencing as “discrimination.”
The underlying assumption here is that platforms should be like telephone networks: providing a way for different sides of a market to communicate with each other, but doing little more than that. When platforms do do more—for example, manipulating search results to favor certain businesses or to give their own products prominence —it is seen as exploitative “leveraging.”
But consumers often want platforms to be more than just a telephone network or directory, because digital markets would be very difficult to navigate without some degree of “discrimination” between sellers. The Internet is so vast and sellers are often so anonymous that any assistance which helps you choose among options can serve to make it more navigable. As John Gruber put it:
From what I’ve seen over the last few decades, the quality of the user experience of every computing platform is directly correlated to the amount of control exerted by its platform owner. The current state of the ownerless world wide web speaks for itself.
Sometimes, this manifests itself as “self-preferencing” of another service, to reduce additional time spent searching for the information you want. When you search for a restaurant on Google, it can be very useful to get information like user reviews, the restaurant’s phone number, a button on mobile to phone them directly, estimates of how busy it is, and a link to a Maps page to see how to actually get there.
This is, undoubtedly, frustrating for competitors like Yelp, who would like this information not to be there and for users to have to click on either a link to Yelp or a link to Google Maps. But whether it is good or bad for Yelp isn’t relevant to whether it is good for users—and it is at least arguable that it is, which makes a blanket prohibition on this kind of behavior almost inevitably harmful.
If it isn’t obvious why removing this kind of feature would be harmful for users, ask yourself why some users search in Yelp’s app directly for this kind of result. The answer, I think, is that Yelp gives you all the information above that Google does (and sometimes is better, although I tend to trust Google Maps’ reviews over Yelp’s), and it’s really convenient to have all that on the same page. If Google could not provide this kind of “rich” result, many users would probably stop using Google Search to look for restaurant information in the first place, because a new friction would have been added that made the experience meaningfully worse. Removing that option would be good for Yelp, but mainly because it removes a competitor.
If all this feels like stating the obvious, then it should highlight a significant problem with Section 2(a) in the Cicilline bill: it prohibits conduct that is directly value-adding for consumers, and that creates competition for dedicated services like Yelp that object to having to compete with this kind of conduct.
Some or all of this behavior would be prohibited under Section 2(a) of the Cicilline bill. Combined with the bill’s presumption that conduct must be defended affirmatively—that is, the platform is presumed guilty unless it can prove that the challenged conduct is pro-competitive, which may be very difficult to do—and the bill could prospectively eliminate a huge range of socially valuable behavior.
Supporters of the bill have already been left arguing that the law simply wouldn’t be enforced in these cases of benign discrimination. But this would hardly be an improvement. It would mean the Federal Trade Commission (FTC) and U.S. Justice Department (DOJ) have tremendous control over how these platforms are built, since they could challenge conduct in virtually any case. The regulatory uncertainty alone would complicate the calculus for these firms as they refine, develop, and deploy new products and capabilities.
So one potential compromise might be to do away with this broad-based rule and proscribe specific kinds of “discriminatory” conduct instead. This approach would involve removing Section 2(a) from the bill but retaining Section 2(b), which enumerates 10 practices it deems to be “other discriminatory conduct.” This may seem appealing, as it would potentially avoid the worst abuses of the broad-based prohibition. In practice, however, it would carry many of the same problems. In fact, many of 2(b)’s provisions appear to go even further than 2(a), and would proscribe even more procompetitive conduct that consumers want.
Sections 2(b)(1) and 2(b)(9)
The wording of these provisions is extremely broad and, as drafted, would seem to challenge even the existence of vertically integrated products. As such, these prohibitions are potentially even more extensive and invasive than Section 2(a) would have been. Even a narrower reading here would seem to preclude safety and privacy features that are valuable to many users. iOS’s sandboxing of apps, for example, serves to limit the damage that a malware app can do on a user’s device precisely because of the limitations it imposes on what other features and hardware the app can access.
This provision would preclude a firm from conditioning preferred status on use of another service from that firm. This would likely undermine the purpose of platforms, which is to absorb and counter some of the risks involved in doing business online. An example of this is Amazon’s tying eligibility for its Prime program to sellers that use Amazon’s delivery service (FBA – Fulfilled By Amazon). The bill seems to presume in an example like this that Amazon is leveraging its power in the market—in the form of the value of the Prime label—to profit from delivery. But Amazon could, and already does, charge directly for listing positions; it’s unclear why it would benefit from charging via FBA when it could just charge for the Prime label.
An alternate, simpler explanation is that FBA improves the quality of the service, by granting customers greater assurance that a Prime product will arrive when Amazon says it will. Platforms add value by setting out rules and providing services that reduce the uncertainties between buyers and sellers they’d otherwise experience if they transacted directly with each other. This section’s prohibition—which, as written, would seem to prevent any kind of quality assurance—likely would bar labelling by a platform, even where customers explicitly want it.
As written, this would prohibit platforms from using aggregated data to improve their services at all. If Apple found that 99% of its users uninstalled an app immediately after it was installed, it would be reasonable to conclude that the app may be harmful or broken in some way, and that Apple should investigate. This provision would ban that.
Sections 2(b)(4) and 2(b)(6)
These two provisions effectively prohibit a platform from using information it does not also provide to sellers. Such prohibitions ignore the fact that it is often good for sellers to lack certain information, since withholding information can prevent abuse by malicious users. For example, a seller may sometimes try to bribe their customers to post positive reviews of their products, or even threaten customers who have posted negative ones. Part of the role of a platform is to combat that kind of behavior by acting as a middleman and forcing both consumer users and business users to comply with the platform’s own mechanisms to control that kind of behavior.
If this seems overly generous to platforms—since, obviously, it gives them a lot of leverage over business users—ask yourself why people use platforms at all. It is not a coincidence that people often prefer Amazon to dealing with third-party merchants and having to navigate those merchants’ sites themselves. The assurance that Amazon provides is extremely valuable for users. Much of it comes from the company’s ability to act as a middleman in this way, lowering the transaction costs between buyers and sellers.
This provision restricts the treatment of defaults. It is, however, relatively restrained when compared to, for example, the DOJ’s lawsuit against Google, which treats as anticompetitive even payment for defaults that can be changed. Still, many of the arguments that apply in that case also apply here: default status for apps can be a way to recoup income foregone elsewhere (e.g., a browser provided for free that makes its money by selling the right to be the default search engine).
This section gets to the heart of why “discrimination” can often be procompetitive: that it facilitates competition between platforms. The kind of self-preferencing that this provision would prohibit can allow firms that have a presence in one market to extend that position into another, increasing competition in the process. Both Apple and Amazon have used their customer bases in smartphones and e-commerce, respectively, to grow their customer bases for video streaming, in competition with Netflix, Google’s YouTube, cable television, and each other. If Apple designed a search engine to compete with Google, it would do exactly the same thing, and we would be better off because of it. Restricting this kind of behavior is, perversely, exactly what you would do if you wanted to shield these incumbents from competition.
As with other provisions, this one would preclude one of the mechanisms by which platforms add value: creating assurance for customers about the products they can expect if they visit the platform. Some of this relates to child protection; some of the most frustrating stories involve children being overcharged when they use an iPhone or Android app, and effectively being ripped off because of poor policing of the app (or insufficiently strict pricing rules by Apple or Google). This may also relate to rules that state that the seller cannot offer a cheaper product elsewhere (Amazon’s “General Pricing Rule” does this, for example). Prohibiting this would simply impose a tax on customers who cannot shop around and would prefer to use a platform that they trust has the lowest prices for the item they want.
Ostensibly a “whistleblower” provision, this section could leave platforms with no recourse, not even removing a user from its platform, in response to spurious complaints intended purely to extract value for the complaining business rather than to promote competition. On its own, this sort of provision may be fairly harmless, but combined with the provisions above, it allows the bill to add up to a rent-seekers’ charter.
In each case above, it’s vital to remember that a reversed burden of proof applies. So, there is a high chance that the law will side against the defendant business, and a large downside for conduct that ends up being found to violate these provisions. That means that platforms will likely err on the side of caution in many cases, avoiding conduct that is ambiguous, and society will probably lose a lot of beneficial behavior in the process.
Put together, the provisions undermine much of what has become an Internet platform’s role: to act as an intermediary, de-risk transactions between customers and merchants who don’t know each other, and tweak the rules of the market to maximize its attractiveness as a place to do business. The “discrimination” that the bill would outlaw is, in practice, behavior that makes it easier for consumers to navigate marketplaces of extreme complexity and uncertainty, in which they often know little or nothing about the firms with whom they are trying to transact business.
Customers do not want platforms to be neutral, open utilities. They can choose platforms that are like that already, such as eBay. They generally tend to prefer ones like Amazon, which are not neutral and which carefully cultivate their service to be as streamlined, managed, and “discriminatory” as possible. Indeed, many of people’s biggest complaints with digital platforms relate to their openness: the fake reviews, counterfeit products, malware, and spam that come with letting more unknown businesses use your service. While these may be unavoidable by-products of running a platform, platforms compete on their ability to ferret them out. Customers are unlikely to thank legislators for regulating Amazon into being another eBay.
U.S. and European competition laws diverge in numerous ways that have important real-world effects. Understanding these differences is vital, particularly as lawmakers in the United States, and the rest of the world, consider adopting a more “European” approach to competition.
In broad terms, the European approach is more centralized and political. The European Commission’s Directorate General for Competition (DG Comp) has significant de facto discretion over how the law is enforced. This contrasts with the common law approach of the United States, in which courts elaborate upon open-ended statutes through an iterative process of case law. In other words, the European system was built from the top down, while U.S. antitrust relies on a bottom-up approach, derived from arguments made by litigants (including the government antitrust agencies) and defendants (usually businesses).
This procedural divergence has significant ramifications for substantive law. European competition law includes more provisions akin to de facto regulation. This is notably the case for the “abuse of dominance” standard, in which a “dominant” business can be prosecuted for “abusing” its position by charging high prices or refusing to deal with competitors. By contrast, the U.S. system places more emphasis on actual consumer outcomes, rather than the nature or “fairness” of an underlying practice.
The American system thus affords firms more leeway to exclude their rivals, so long as this entails superior benefits for consumers. This may make the U.S. system more hospitable to innovation, since there is no built-in regulation of conduct for innovators who acquire a successful market position fairly and through normal competition.
In this post, we discuss some key differences between the two systems—including in areas like predatory pricing and refusals to deal—as well as the discretionary power the European Commission enjoys under the European model.
U.S. antitrust is, by and large, unconcerned with companies charging what some might consider “excessive” prices. The late Associate Justice Antonin Scalia, writing for the Supreme Court majority in the 2003 case Verizon v. Trinko, observed that:
The mere possession of monopoly power, and the concomitant charging of monopoly prices, is not only not unlawful; it is an important element of the free-market system. The opportunity to charge monopoly prices—at least for a short period—is what attracts “business acumen” in the first place; it induces risk taking that produces innovation and economic growth.
This contrasts with European competition-law cases, where firms may be found to have infringed competition law because they charged excessive prices. As the European Court of Justice (ECJ) held in 1978’s United Brands case: “In this case charging a price which is excessive because it has no reasonable relation to the economic value of the product supplied would be such an abuse.”
While United Brands was the EU’s foundational case for excessive pricing, and the European Commission reiterated that these allegedly exploitative abuses were possible when it published its guidance paper on abuse of dominance cases in 2009, the commission had for some time demonstrated apparent disinterest in bringing such cases. In recent years, however, both the European Commission and some national authorities have shown renewed interest in excessive-pricing cases, most notably in the pharmaceutical sector.
European competition law also penalizes so-called “margin squeeze” abuses, in which a dominant upstream supplier charges a price to distributors that is too high for them to compete effectively with that same dominant firm downstream:
[I]t is for the referring court to examine, in essence, whether the pricing practice introduced by TeliaSonera is unfair in so far as it squeezes the margins of its competitors on the retail market for broadband connection services to end users. (Konkurrensverket v TeliaSonera Sverige, 2011)
As Scalia observed in Trinko, forcing firms to charge prices that are below a market’s natural equilibrium affects firms’ incentives to enter markets, notably with innovative products and more efficient means of production. But the problem is not just one of market entry and innovation. Also relevant is the degree to which competition authorities are competent to determine the “right” prices or margins.
As Friedrich Hayek demonstrated in his influential 1945 essay The Use of Knowledge in Society, economic agents use information gleaned from prices to guide their business decisions. It is this distributed activity of thousands or millions of economic actors that enables markets to put resources to their most valuable uses, thereby leading to more efficient societies. By comparison, the efforts of central regulators to set prices and margins is necessarily inferior; there is simply no reasonable way for competition regulators to make such judgments in a consistent and reliable manner.
Given the substantial risk that investigations into purportedly excessive prices will deter market entry, such investigations should be circumscribed. But the court’s precedents, with their myopic focus on ex post prices, do not impose such constraints on the commission. The temptation to “correct” high prices—especially in the politically contentious pharmaceutical industry—may thus induce economically unjustified and ultimately deleterious intervention.
Monopolists must charge prices that are below some measure of their incremental costs; and
There must be a realistic prospect that they will able to recoup these initial losses.
In laying out its approach to predatory pricing, the U.S. Supreme Court has identified the risk of false positives and the clear cost of such errors to consumers. It thus has particularly stressed the importance of the recoupment requirement. As the court found in 1993’s Brooke Group Ltd. v. Brown & Williamson Tobacco Corp., without recoupment, “predatory pricing produces lower aggregate prices in the market, and consumer welfare is enhanced.”
Accordingly, U.S. authorities must prove that there are constraints that prevent rival firms from entering the market after the predation scheme, or that the scheme itself would effectively foreclose rivals from entering the market in the first place. Otherwise, the predator would be undercut by competitors as soon as it attempts to recoup its losses by charging supra-competitive prices.
Without the strong likelihood that a monopolist will be able to recoup lost revenue from underpricing, the overwhelming weight of economic evidence (to say nothing of simple logic) is that predatory pricing is not a rational business strategy. Thus, apparent cases of predatory pricing are most likely not, in fact, predatory; deterring or punishing them would actually harm consumers.
[I]t does not follow from the case‑law of the Court that proof of the possibility of recoupment of losses suffered by the application, by an undertaking in a dominant position, of prices lower than a certain level of costs constitutes a necessary precondition to establishing that such a pricing policy is abusive. (France Télécom v Commission, 2009).
This aspect of the legal standard has no basis in economic theory or evidence—not even in the “strategic” economic theory that arguably challenges the dominant Chicago School understanding of predatory pricing. Indeed, strategic predatory pricing still requires some form of recoupment, and the refutation of any convincing business justification offered in response. For example, in a 2017 piece for the Antitrust Law Journal, Steven Salop lays out the “raising rivals’ costs” analysis of predation and notes that recoupment still occurs, just at the same time as predation:
[T]he anticompetitive conditional pricing practice does not involve discrete predatory and recoupment periods, as in the case of classical predatory pricing. Instead, the recoupment occurs simultaneously with the conduct. This is because the monopolist is able to maintain its current monopoly power through the exclusionary conduct.
The case of predatory pricing illustrates a crucial distinction between European and American competition law. The recoupment requirement embodied in American antitrust law serves to differentiate aggressive pricing behavior that improves consumer welfare—because it leads to overall price decreases—from predatory pricing that reduces welfare with higher prices. It is, in other words, entirely focused on the welfare of consumers.
The European approach, by contrast, reflects structuralist considerations far removed from a concern for consumer welfare. Its underlying fear is that dominant companies could use aggressive pricing to engender more concentrated markets. It is simply presumed that these more concentrated markets are invariably detrimental to consumers. Both the Tetra Pak and France Télécom cases offer clear illustrations of the ECJ’s reasoning on this point:
[I]t would not be appropriate, in the circumstances of the present case, to require in addition proof that Tetra Pak had a realistic chance of recouping its losses. It must be possible to penalize predatory pricing whenever there is a risk that competitors will be eliminated… The aim pursued, which is to maintain undistorted competition, rules out waiting until such a strategy leads to the actual elimination of competitors. (Tetra Pak v Commission, 1996).
[T]he lack of any possibility of recoupment of losses is not sufficient to prevent the undertaking concerned reinforcing its dominant position, in particular, following the withdrawal from the market of one or a number of its competitors, so that the degree of competition existing on the market, already weakened precisely because of the presence of the undertaking concerned, is further reduced and customers suffer loss as a result of the limitation of the choices available to them. (France Télécom v Commission, 2009).
In short, the European approach leaves less room to analyze the concrete effects of a given pricing scheme, leaving it more prone to false positives than the U.S. standard explicated in the Brooke Group decision. Worse still, the European approach ignores not only the benefits that consumers may derive from lower prices, but also the chilling effect that broad predatory pricing standards may exert on firms that would otherwise seek to use aggressive pricing schemes to attract consumers.
Refusals to Deal
U.S. and EU antitrust law also differ greatly when it comes to refusals to deal. While the United States has limited the ability of either enforcement authorities or rivals to bring such cases, EU competition law sets a far lower threshold for liability.
As Justice Scalia wrote in Trinko:
Aspen Skiing is at or near the outer boundary of §2 liability. The Court there found significance in the defendant’s decision to cease participation in a cooperative venture. The unilateral termination of a voluntary (and thus presumably profitable) course of dealing suggested a willingness to forsake short-term profits to achieve an anticompetitive end. (Verizon v Trinko, 2003.)
This highlights two key features of American antitrust law with regard to refusals to deal. To start, U.S. antitrust law generally does not apply the “essential facilities” doctrine.Accordingly, in the absence of exceptional facts, upstream monopolists are rarely required to supply their product to downstream rivals, even if that supply is “essential” for effective competition in the downstream market. Moreover, as Justice Scalia observed in Trinko, the Aspen Skiing case appears to concern only those limited instances where a firm’s refusal to deal stems from the termination of a preexisting and profitable business relationship.
While even this is not likely the economically appropriate limitation on liability, its impetus—ensuring that liability is found only in situations where procompetitive explanations for the challenged conduct are unlikely—is completely appropriate for a regime concerned with minimizing the cost to consumers of erroneous enforcement decisions.
In practice, however, all of these conditions have been relaxed significantly by EU courts and the commission’s decisional practice. This is best evidenced by the lower court’s Microsoft ruling where, as John Vickers notes:
[T]he Court found easily in favor of the Commission on the IMS Health criteria, which it interpreted surprisingly elastically, and without relying on the special factors emphasized by the Commission. For example, to meet the “new product” condition it was unnecessary to identify a particular new product… thwarted by the refusal to supply but sufficient merely to show limitation of technical development in terms of less incentive for competitors to innovate.
EU competition law thus shows far less concern for its potential chilling effect on firms’ investments than does U.S. antitrust law.
There are vast differences between U.S. and EU competition law relating to vertical restraints—that is, contractual restraints between firms that operate at different levels of the production process.
On the one hand, since the Supreme Court’s Leegin ruling in 2006, even price-related vertical restraints (such as resale price maintenance (RPM), under which a manufacturer can stipulate the prices at which retailers must sell its products) are assessed under the rule of reason in the United States. Some commentators have gone so far as to say that, in practice, U.S. case law on RPM almost amounts to per se legality.
Furthermore, in the Consten and Grundig ruling, the ECJ rejected the consequentialist, and economically grounded, principle that inter-brand competition is the appropriate framework to assess vertical restraints:
This treatment of vertical restrictions flies in the face of longstanding mainstream economic analysis of the subject. As Patrick Rey and Jean Tirole conclude:
Another major contribution of the earlier literature on vertical restraints is to have shown that per se illegality of such restraints has no economic foundations.
Unlike the EU, the U.S. Supreme Court in Leegintook account of the weight of the economic literature, and changed its approach to RPM to ensure that the law no longer simply precluded its arguable consumer benefits, writing: “Though each side of the debate can find sources to support its position, it suffices to say here that economics literature is replete with procompetitive justifications for a manufacturer’s use of resale price maintenance.” Further, the court found that the prior approach to resale price maintenance restraints “hinders competition and consumer welfare because manufacturers are forced to engage in second-best alternatives and because consumers are required to shoulder the increased expense of the inferior practices.”
The EU’s continued per se treatment of RPM, by contrast, strongly reflects its “precautionary principle” approach to antitrust. European regulators and courts readily condemn conduct that could conceivably injure consumers, even where such injury is, according to the best economic understanding, exceedingly unlikely. The U.S. approach, which rests on likelihood rather than mere possibility, is far less likely to condemn beneficial conduct erroneously.
Political Discretion in European Competition Law
EU competition law lacks a coherent analytical framework like that found in U.S. law’s reliance on the consumer welfare standard. The EU process is driven by a number of laterally equivalent—and sometimes mutually exclusive—goals, including industrial policy and the perceived need to counteract foreign state ownership and subsidies. Such a wide array of conflicting aims produces lack of clarity for firms seeking to conduct business. Moreover, the discretion that attends this fluid arrangement of goals yields an even larger problem.
The Microsoft case illustrates this problem well. In Microsoft, the commission could have chosen to base its decision on various potential objectives. It notably chose to base its findings on the fact that Microsoft’s behavior reduced “consumer choice.”
The commission, in fact, discounted arguments that economic efficiency may lead to consumer welfare gains, because it determined “consumer choice” among media players was more important:
Another argument relating to reduced transaction costs consists in saying that the economies made by a tied sale of two products saves resources otherwise spent for maintaining a separate distribution system for the second product. These economies would then be passed on to customers who could save costs related to a second purchasing act, including selection and installation of the product. Irrespective of the accuracy of the assumption that distributive efficiency gains are necessarily passed on to consumers, such savings cannot possibly outweigh the distortion of competition in this case. This is because distribution costs in software licensing are insignificant; a copy of a software programme can be duplicated and distributed at no substantial effort. In contrast, the importance of consumer choice and innovation regarding applications such as media players is high. (Commission Decision No. COMP. 37792 (Microsoft)).
It may be true that tying the products in question was unnecessary. But merely dismissing this decision because distribution costs are near-zero is hardly an analytically satisfactory response. There are many more costs involved in creating and distributing complementary software than those associated with hosting and downloading. The commission also simply asserts that consumer choice among some arbitrary number of competing products is necessarily a benefit. This, too, is not necessarily true, and the decision’s implication that any marginal increase in choice is more valuable than any gains from product design or innovation is analytically incoherent.
The Court of First Instance was only too happy to give the commission a pass in its breezy analysis; it saw no objection to these findings. With little substantive reasoning to support its findings, the court fully endorsed the commission’s assessment:
As the Commission correctly observes (see paragraph 1130 above), by such an argument Microsoft is in fact claiming that the integration of Windows Media Player in Windows and the marketing of Windows in that form alone lead to the de facto standardisation of the Windows Media Player platform, which has beneficial effects on the market. Although, generally, standardisation may effectively present certain advantages, it cannot be allowed to be imposed unilaterally by an undertaking in a dominant position by means of tying.
The Court further notes that it cannot be ruled out that third parties will not want the de facto standardisation advocated by Microsoft but will prefer it if different platforms continue to compete, on the ground that that will stimulate innovation between the various platforms. (Microsoft Corp. v Commission, 2007)
Pointing to these conflicting effects of Microsoft’s bundling decision, without weighing either, is a weak basis to uphold the commission’s decision that consumer choice outweighs the benefits of standardization. Moreover, actions undertaken by other firms to enhance consumer choice at the expense of standardization are, on these terms, potentially just as problematic. The dividing line becomes solely which theory the commission prefers to pursue.
What such a practice does is vest the commission with immense discretionary power. Any given case sets up a “heads, I win; tails, you lose” situation in which defendants are easily outflanked by a commission that can change the rules of its analysis as it sees fit. Defendants can play only the cards that they are dealt. Accordingly, Microsoft could not successfully challenge a conclusion that its behavior harmed consumers’ choice by arguing that it improved consumer welfare, on net.
By selecting, in this instance, “consumer choice” as the standard to be judged, the commission was able to evade the constraints that might have been imposed by a more robust welfare standard. Thus, the commission can essentially pick and choose the objectives that best serve its interests in each case. This vastly enlarges the scope of potential antitrust liability, while also substantially decreasing the ability of firms to predict when their behavior may be viewed as problematic. It leads to what, in U.S. courts, would be regarded as an untenable risk of false positives that chill innovative behavior and create nearly unwinnable battles for targeted firms.
From Sen. Elizabeth Warren (D-Mass.) to Sen. Josh Hawley (R-Mo.), populist calls to “fix” our antitrust laws and the underlying Consumer Welfare Standard have found a foothold on Capitol Hill. At the same time, there are calls to “fix” the Supreme Court by packing it with new justices. The court’s unanimous decision in NCAA v. Alston demonstrates that neither needs repair. To the contrary, clearly anti-competitive conduct—like the NCAA’s compensation rules—is proscribed under the Consumer Welfare Standard, and every justice from Samuel Alito to Sonia Sotomayor can agree on that.
In 1984, the court in NCAA v. Board of Regents suggested that “courts should take care when assessing the NCAA’s restraints on student-athlete compensation.” After all, joint ventures like sports leagues are entitled to rule-of-reason treatment. But while times change, the Consumer Welfare Standard is sufficiently flexible to meet those changes.
Where a competitive restraint exists primarily to ensure that “enormous sums of money flow to seemingly everyone except the student athletes,” the court rightly calls it out for what it is. As Associate Justice Brett Kavanaugh wrote in his concurrence:
Nowhere else in America can businesses get away with agreeing not to pay their workers a fair market rate on the theory that their product is defined by not paying their workers a fair market rate. And under ordinary principles of antitrust law, it is not evident why college sports should be any different. The NCAA is not above the law.
Disturbing these “ordinary principles”—whether through legislation, administrative rulemaking, or the common law—is simply unnecessary. For example, the Open Markets Institute filed an amicus brief arguing that the rule of reason should be “bounded” and willfully blind to the pro-competitive benefits some joint ventures can create (an argument that has been used, unsuccessfully, to attack ridesharing services like Uber and Lyft). Sen. Amy Klobuchar (D-Minn.) has proposed shifting the burden of proof so that merging parties are guilty until proven innocent. Sen. Warren would go further, deeming Amazon’s acquisition of Whole Foods anti-competitive simply because the company is “big,” and ignoring the merger’s myriad pro-competitive benefits. Sen. Hawley has gone further still: calling on Amazon to be investigated criminally for the crime of being innovative and successful.
Several of the current proposals, including those from Sens. Klobuchar and Hawley (and those recently introduced in the House that essentially single out firms for disfavored treatment), would replace the Consumer Welfare Standard that has underpinned antitrust law for decades with a policy that effectively punishes firms for being politically unpopular.
These examples demonstrate we should be wary when those in power assert that things are so irreparably broken that they need a complete overhaul. The “solutions” peddled usually increase politicians’ power by enabling them to pick winners and losers through top-down approaches that stifle the bottom-up innovations that make consumers’ lives better.
Are antitrust law and the Supreme Court perfect? Hardly. But in a 9-0 decision, the court proved this week that there’s nothing broken about either.
Democratic leadership of the House Judiciary Committee have leaked the approach they plan to take to revise U.S. antitrust law and enforcement, with a particular focus on digital platforms.
Broadly speaking, the bills would: raise fees for larger mergers and increase appropriations to the FTC and DOJ; require data portability and interoperability; declare that large platforms can’t own businesses that compete with other businesses that use the platform; effectively ban large platforms from making any acquisitions; and generally declare that large platforms cannot preference their own products or services.
All of these are ideas that have been discussed before. They are very much in line with the EU’s approach to competition, which places more regulation-like burdens on big businesses, and which is introducing a Digital Markets Act that mirrors the Democrats’ proposals. Some Republicans are reportedly supportive of the proposals, which is surprising since they mean giving broad, discretionary powers to antitrust authorities that are controlled by Democrats who take an expansive view of antitrust enforcement as a way to achieve their other social and political goals. The proposals may also be unpopular with consumers if, for example, they would mean that popular features like integrating Maps into relevant Google Search results becomes prohibited.
The multi-bill approach here suggests that the committee is trying to throw as much at the wall as possible to see what sticks. It may reflect a lack of confidence among the proposers in their ability to get their proposals through wholesale, especially given that Amy Klobuchar’s CALERA bill in the Senate creates an alternative that, while still highly interventionist, does not create ex ante regulation of the Internet the same way these proposals do.
In general, the bills are misguided for three main reasons.
One, they seek to make digital platforms into narrow conduits for other firms to operate on, ignoring the value created by platforms curating their own services by, for example, creating quality controls on entry (as Apple does on its App Store) or by integrating their services with related products (like, say, Google adding events from Gmail to users’ Google Calendars).
Two, they ignore the procompetitive effects of digital platforms extending into each other’s markets and competing with each other there, in ways that often lead to far more intense competition—and better outcomes for consumers—than if the only firms that could compete with the incumbent platform were small startups.
Three, they ignore the importance of incentives for innovation. Platforms invest in new and better products when they can make money from doing so, and limiting their ability to do that means weakened incentives to innovate. Startups and their founders and investors are driven, in part, by the prospect of being acquired, often by the platforms themselves. Making those acquisitions more difficult, or even impossible, means removing one of the key ways startup founders can exit their firms, and hence one of the key rewards and incentives for starting an innovative new business.
The flagship bill, introduced by Antitrust Subcommittee Chairman David Cicilline (D-R.I.), establishes a definition of “covered platform” used by several of the other bills. The measures would apply to platforms with at least 500,000 U.S.-based users, a market capitalization of more than $600 billion, and that is deemed a “critical trading partner” with the ability to restrict or impede the access that a “dependent business” has to its users or customers.
Cicilline’s bill would bar these covered platforms from being able to promote their own products and services over the products and services of competitors who use the platform. It also defines a number of other practices that would be regarded as discriminatory, including:
Restricting or impeding “dependent businesses” from being able to access the platform or its software on the same terms as the platform’s own lines of business;
Conditioning access or status on purchasing other products or services from the platform;
Using user data to support the platform’s own products in ways not extended to competitors;
Restricting the platform’s commercial users from using or accessing data generated on the platform from their own customers;
Restricting platform users from uninstalling software pre-installed on the platform;
Restricting platform users from providing links to facilitate business off of the platform;
Preferencing the platform’s own products or services in search results or rankings;
Interfering with how a dependent business prices its products;
Impeding a dependent business’ users from connecting to services or products that compete with those offered by the platform; and
Retaliating against users who raise concerns with law enforcement about potential violations of the act.
On a basic level, these would prohibit lots of behavior that is benign and that can improve the quality of digital services for users. Apple pre-installing a Weather app on the iPhone would, for example, run afoul of these rules, and the rules as proposed could prohibit iPhones from coming with pre-installed apps at all. Instead, users would have to manually download each app themselves, if indeed Apple was allowed to include the App Store itself pre-installed on the iPhone, given that this competes with other would-be app stores.
Apart from the obvious reduction in the quality of services and convenience for users that this would involve, this kind of conduct (known as “self-preferencing”) is usually procompetitive. For example, self-preferencing allows platforms to compete with one another by using their strength in one market to enter a different one; Google’s Shopping results in the Search page increase the competition that Amazon faces, because it presents consumers with a convenient alternative when they’re shopping online for products. Similarly, Amazon’s purchase of the video-game streaming service Twitch, and the self-preferencing it does to encourage Amazon customers to use Twitch and support content creators on that platform, strengthens the competition that rivals like YouTube face.
It also helps innovation, because it gives firms a reason to invest in services that would otherwise be unprofitable for them. Google invests in Android, and gives much of it away for free, because it can bundle Google Search into the OS, and make money from that. If Google could not self-preference Google Search on Android, the open source business model simply wouldn’t work—it wouldn’t be able to make money from Android, and would have to charge for it in other ways that may be less profitable and hence give it less reason to invest in the operating system.
This behavior can also increase innovation by the competitors of these companies, both by prompting them to improve their products (as, for example, Google Android did with Microsoft’s mobile operating system offerings) and by growing the size of the customer base for products of this kind. For example, video games published by console manufacturers (like Nintendo’s Zelda and Mario games) are often blockbusters that grow the overall size of the user base for the consoles, increasing demand for third-party titles as well.
Sponsored by Rep. Pramila Jayapal (D-Wash.), this bill would make it illegal for covered platforms to control lines of business that pose “irreconcilable conflicts of interest,” enforced through civil litigation powers granted to the Federal Trade Commission (FTC) and the U.S. Justice Department (DOJ).
Specifically, the bill targets lines of business that create “a substantial incentive” for the platform to advantage its own products or services over those of competitors that use the platform, or to exclude or disadvantage competing businesses from using the platform. The FTC and DOJ could potentially order that platforms divest lines of business that violate the act.
This targets similar conduct as the previous bill, but involves the forced separation of different lines of business. It also appears to go even further, seemingly implying that companies like Google could not even develop services like Google Maps or Chrome because their existence would create such “substantial incentives” to self-preference them over the products of their competitors.
Apart from the straightforward loss of innovation and product developments this would involve, requiring every tech company to be narrowly focused on a single line of business would substantially entrench Big Tech incumbents, because it would make it impossible for them to extend into adjacent markets to compete with one another. For example, Apple could not develop a search engine to compete with Google under these rules, and Amazon would be forced to sell its video-streaming services that compete with Netflix and Youtube.
Introduced by Rep. Hakeem Jeffries (D-N.Y.), this bill would bar covered platforms from making essentially any acquisitions at all. To be excluded from the ban on acquisitions, the platform would have to present “clear and convincing evidence” that the acquired business does not compete with the platform for any product or service, does not pose a potential competitive threat to the platform, and would not in any way enhance or help maintain the acquiring platform’s market position.
So this proposal would probably reduce investment in U.S. startups, since it makes it more difficult for them to be acquired. It would therefore reduce innovation as a result. It would also reduce inter-platform competition by banning deals that allow firms to move into new markets, like the acquisition of Beats that helped Apple to build a Spotify competitor, or the deals that helped Google, Microsoft, and Amazon build cloud-computing services that all compete with each other. It could also reduce competition faced by old industries, by preventing tech companies from buying firms that enable it to move into new markets—like Amazon’s acquisitions of health-care companies that it has used to build a health-care offering. Even Walmart’s acquisition of Jet.com, which it has used to build an Amazon competitor, could have been banned under this law if Walmart had had a higher market cap at the time.
Under terms of the legislation, covered platforms would be required to allow third parties to transfer data to their users or, with the user’s consent, to a competing business. It also would require platforms to facilitate compatible and interoperable communications with competing businesses. The law directs the FTC to establish technical committees to promulgate the standards for portability and interoperability.
It can also make digital services more buggy and unreliable, by requiring that they are built in a more “open” way that may be more prone to unanticipated software mismatches. A good example is that of Windows vs iOS; Windows is far more interoperable with third-party software than iOS is, but tends to be less stable as a result, and users often prefer the closed, stable system.
Interoperability requirements also entail ongoing regulatory oversight, to make sure data is being provided to third parties reliably. It’s difficult to build an app around another company’s data without assurance that the data will be available when users want it. For a requirement as broad as this bill’s, that could mean setting up quite a large new de facto regulator.
In the UK, Open Banking (an interoperability requirement imposed on British retail banks) has suffered from significant service outages, and targets a level of uptime that many developers complain is too low for them to build products around. Nor has Open Banking yet led to any obvious competition benefits.
A bill that mirrors language in the Endless Frontier Act recently passed by the U.S. Senate, would significantly raise filing fees for the largest mergers. Rather than the current cap of $280,000 for mergers valued at more than $500 million, the bill—sponsored by Rep. Joe Neguse (D-Colo.)–the new schedule would assess fees of $2.25 million for mergers valued at more than $5 billion; $800,000 for those valued at between $2 billion and $5 billion; and $400,000 for those between $1 billion and $2 billion.
Smaller mergers would actually see their filing fees cut: from $280,000 to $250,000 for those between $500 million and $1 billion; from $125,000 to $100,000 for those between $161.5 million and $500 million; and from $45,000 to $30,000 for those less than $161.5 million.
In addition, the bill would appropriate $418 million to the FTC and $252 million to the DOJ’s Antitrust Division for Fiscal Year 2022. Most people in the antitrust world are generally supportive of more funding for the FTC and DOJ, although whether this is actually good or not depends both on how it’s spent at those places.
It’s hard to object if it goes towards deepening the agencies’ capacities and knowledge, by hiring and retaining higher quality staff with salaries that are more competitive with those offered by the private sector, and on greater efforts to study the effects of the antitrust laws and past cases on the economy. If it goes toward broadening the activities of the agencies, by doing more and enabling them to pursue a more aggressive enforcement agenda, and supporting whatever of the above proposals make it into law, then it could be very harmful.
The European Commission recently issued a formal Statement of Objections (SO) in which it charges Apple with antitrust breach. In a nutshell, the commission argues that Apple prevents app developers—in this case, Spotify—from using alternative in-app purchase systems (IAPs) other than Apple’s own, or steering them towards other, cheaper payment methods on another site. This, the commission says, results in higher prices for consumers in the audio streaming and ebook/audiobook markets.
More broadly, the commission claims that Apple’s App Store rules may distort competition in markets where Apple competes with rival developers (such as how Apple Music competes with Spotify). This explains why the anticompetitive concerns raised by Spotify regarding the Apple App Store rules have now expanded to Apple’s e-books, audiobooks and mobile payments platforms.
However, underlying market realities cast doubt on the commission’s assessment. Indeed, competition from Google Play and other distribution mediums makes it difficult to state unequivocally that the relevant market should be limited to Apple products. Likewise, the conduct under investigation arguably solves several problems relating to platform dynamics, and consumers’ privacy and security.
Should the relevant market be narrowed to iOS?
An important first question is whether there is a distinct, antitrust-relevant market for “music streaming apps distributed through the Apple App Store,” as the EC posits.
This market definition is surprising, given that it is considerably narrower than the one suggested by even the most enforcement-minded scholars. For instance, Damien Geradin and Dimitrias Katsifis—lawyers for app developers opposed to Apple—define the market as “that of app distribution on iOS devices, a two-sided transaction market on which Apple has a de facto monopoly.” Similarly, a report by the Dutch competition authority declared that the relevant market was limited to the iOS App Store, due to the lack of interoperability with other systems.
The commission’s decisional practice has been anything but constant in this space. In the Apple/Shazam and Apple/Beats cases, it did not place competing mobile operating systems and app stores in separate relevant markets. Conversely, in the Google Android decision, the commission found that the Android OS and Apple’s iOS, including Google Play and Apple’s App Store, did not compete in the same relevant market. The Spotify SO seems to advocate for this definition, narrowing it even further to music streaming services.
However, this narrow definition raises several questions. Market definition is ultimately about identifying the competitive constraints that the firm under investigation faces. As Gregory Werden puts it: “the relevant market in an antitrust case […] identifies the competitive process alleged to be harmed.”
In that regard, there is clearly somecompetition between Apple’s App Store, Google Play and other app stores (whether this is sufficient to place them in the same relevant market is an empirical question).
This view is supported by the vast number of online posts comparing Android and Apple and advising consumers on their purchasing options. Moreover, the growth of high-end Android devices that compete more directly with the iPhone has reinforced competition between the two firms. Likewise, Apple has moved down the value chain; the iPhone SE, priced at $399, competes with other medium-range Android devices.
App developers have also suggested they view Apple and Android as alternatives. They take into account technical differences to decide between the two, meaning that these two platforms compete with each other for developers.
All of this suggests that the App Store may be part of a wider market for the distribution of apps and services, where Google Play and other app stores are included—though this is ultimately an empirical question (i.e., it depends on the degree of competition between both platforms)
If the market were defined this way, Apple would not even be close to holding a dominant position—a prerequisite for European competition intervention. Indeed, Apple only sold 27.43% of smartphones in March 2021. Similarly, only 30.41% of smartphones in use run iOS, as of March 2021. This is well below the lowest market share in a European abuse of dominance—39.7% in the British Airways decision.
The sense that Apple and Android compete for users and developers is reinforced by recent price movements. Apple dropped its App Store commission fees from 30% to 15% in November 2020 and Google followed suit in March 2021. This conduct is consistent with at least some degree of competition between the platforms. It is worth noting that other firms, notably Microsoft, have so far declined to follow suit (except for gaming apps).
Barring further evidence, neither Apple’s market share nor its behavior appear consistent with the commission’s narrow market definition.
Are Apple’s IAP system rules and anti-steering provisions abusive?
The commission’s case rests on the idea that Apple leverages its IAP system to raise the costs of rival app developers:
“Apple’s rules distort competition in the market for music streaming services by raising the costs of competing music streaming app developers. This in turn leads to higher prices for consumers for their in-app music subscriptions on iOS devices. In addition, Apple becomes the intermediary for all IAP transactions and takes over the billing relationship, as well as related communications for competitors.”
However, expropriating rents from these developers is not nearly as attractive as it might seem. The report of the Dutch competition notes that “attracting and maintaining third-party developers that increase the value of the ecosystem” is essential for Apple. Indeed, users join a specific platform because it provides them with a wide number of applications they can use on their devices. And the opposite applies to developers. Hence, the loss of users on either or both sides reduces the value provided by the Apple App Store. Following this logic, it would make no sense for Apple to systematically expropriate developers. This might partly explain why Apple’s fees are only 30%-15%, since in principle they could be much higher.
It is also worth noting that Apple’s curated App Store and IAP have several redeeming virtues. Apple offers “a highly curated App Store where every app is reviewed by experts and an editorial team helps users discover new apps every day.”While this has arguably turned the App Store into a relatively closed platform, it provides users with the assurance that the apps they find there will meet a standard of security and trustworthiness.
As noted by the Dutch competition authority, “one of the reasons why the App Store is highly valued is because of the strict review process. Complaints about malware spread via an app downloaded in the App Store are rare.” Apple provides users with a special degree of privacy and security. Indeed, Apple stopped more than $1.5 billion in potentially fraudulent transactions in 2020, proving that the security protocols are not only necessary, but also effective. In this sense, the App Store Review Guidelines are considered the first line of defense against fraud and privacy breaches.
It is also worth noting that Apple only charges a nominal fee for iOS developer kits and no fees for in-app advertising. The IAP is thus essential for Apple to monetize the platform and to cover the costs associated with running the platform (note that Apple does make money on device sales, but that revenue is likely constrained by competition between itself and Android). When someone downloads Spotify from the App Store, Apple does not get paid, but Spotify does get a new client. Thus, while independent developers bear the costs of the app fees, Apple bears the costs and risks of running the platform itself.
For instance, Apple’s App Store Team is divided into smaller teams: the Editorial Design team, the Business Operations team, and the Engineering R&D team. These teams each have employees, budgets, and resources for which Apple needs to pay. If the revenues stopped, one can assume that Apple would have less incentive to sustain all these teams that preserve the App Store’s quality, security, and privacy parameters.
Indeed, the IAP system itself provides value to the Apple App Store. Instead of charging all of the apps it provides, it takes a share of the income from some of them. As a result, large developers that own in-app sales contribute to the maintenance of the platform, while smaller ones are still offered to consumers without having to contribute economically. This boosts Apple’s App Store diversity and supply of digital goods and services.
If Apple was forced to adopt another system, it could start charging higher prices for access to its interface and tools, leading to potential discrimination against the smaller developers. Or, Apple could increase the prices of handset devices, thus incurring higher costs for consumers who do not purchase digital goods. Therefore, there are no apparent alternatives to the current IAP that satisfy the App Store’s goals in the same way.
As the Apple Review Guidelines emphasize, “for everything else there is always the open Internet.” Netflix and Spotify have ditched the subscription options from their app, and they are still among the top downloaded apps in iOS. The IAP system is therefore not compulsory to be successful in Apple’s ecosystem, and developers are free to drop Apple Review Guidelines.
The commission’s case against Apple is based on shaky foundations. Not only is the market definition extremely narrow—ignoring competition from Android, among others—but the behavior challenged by the commission has a clear efficiency-enhancing rationale. Of course, both of these critiques ultimately boil down to empirical questions that the commission will have overcome before it reaches a final decision. In the meantime, the jury is out.
AT&T’s $102 billion acquisition of Time Warner in 2019 will go down in M&A history as an exceptionally ill-advised transaction, resulting in the loss of tens of billions of dollars of shareholder value. It should also go down in history as an exceptional ill-chosen target of antitrust intervention. The U.S. Department of Justice, with support from many academic and policy commentators, asserted with confidence that the vertical combination of these content and distribution powerhouses would result in an entity that could exercise market power to the detriment of competitors and consumers.
The chorus of condemnation continued with vigor even after the DOJ’s loss in court and AT&T’s consummation of the transaction. With AT&T’s May 17 announcement that it will unwind the two-year-old acquisition and therefore abandon its strategy to integrate content and distribution, it is clear these predictions of impending market dominance were unfounded.
This widely shared overstatement of antitrust risk derives from a simple but fundamental error: regulators and commentators were looking at the wrong market.
The DOJ’s Antitrust Case against the Transaction
The business case for the AT&T/Time Warner transaction was straightforward: it promised to generate synergies by combining a leading provider of wireless, broadband, and satellite television services with a leading supplier of video content. The DOJ’s antitrust case against the transaction was similarly straightforward: the combined entity would have the ability to foreclose “must have” content from other “pay TV” (cable and satellite television) distributors, resulting in adverse competitive effects.
This foreclosure strategy was expected to take two principal forms. First, AT&T could temporarily withhold (or threaten to withhold) content from rival distributors absent payment of a higher carriage fee, which would then translate into higher fees for subscribers. Second, AT&T could permanently withhold content from rival distributors, who would then lose subscribers to AT&T’s DirectTV satellite television service, further enhancing AT&T’s market power.
Many commentators, both in the trade press and significant portions of the scholarly community, characterized the transaction as posing a high-risk threat to competitive conditions in the pay TV market. These assertions reflected the view that the new entity would exercise a bottleneck position over video-content distribution in the pay TV market and would exercise that power to impose one-sided terms to the detriment of content distributors and consumers.
Notwithstanding this bevy of endorsements, the DOJ’s case was rejected by the district court and the decision was upheld by the D.C. appellate court. The district judge concluded that the DOJ had failed to show that the combined entity would exercise any credible threat to withhold “must have” content from distributors. A key reason: the lost carriage fees AT&T would incur if it did withhold content were so high, and the migration of subscribers from rival pay TV services so speculative, that it would represent an obviously irrational business strategy. In short: no sophisticated business party would ever take AT&T’s foreclosure threat seriously, in which case the DOJ’s predictions of market power were insufficiently compelling to justify the use of government power to block the transaction.
The Fundamental Flaws in the DOJ’s Antitrust Case
The logical and factual infirmities of the DOJ’s foreclosure hypothesis have been extensively and ably covered elsewhere and I will not repeat that analysis. Following up on my previous TOTM commentary on the transaction, I would like to emphasize the point that the DOJ’s case against the transaction was flawed from the outset for two more fundamental reasons.
False Assumption #1
The assumption that the combined entity could withhold so-called “must have” content to cause significant and lasting competitive injury to rival distributors flies in the face of market realities. Content is an abundant, renewable, and mobile resource. There are few entry barriers to the content industry: a commercially promising idea will likely attract capital, which will in turn secure the necessary equipment and personnel for production purposes. Any rival distributor can access a rich menu of valuable content from a plethora of sources, both domestically and worldwide, each of which can provide new content, as required. Even if the combined entity held a license to distribute purportedly “must have” content, that content would be up for sale (more precisely, re-licensing) to the highest bidder as soon as the applicable contract term expired. This is not mere theorizing: it is a widely recognized feature of the entertainment industry.
False Assumption #2
Even assuming the combined entity could wield a portfolio of “must have” content to secure a dominant position in the pay TV market and raise content acquisition costs for rival pay TV services, it still would lack any meaningful pricing power in the relevant consumer market. The reason: significant portions of the viewing population do not want any pay TV or only want dramatically “slimmed-down” packages. Instead, viewers increasingly consume content primarily through video-streaming services—a market in which platforms such as Amazon and Netflix already enjoyed leading positions at the time of the transaction. Hence, even accepting the DOJ’s theory that the combined entity could somehow monopolize the pay TV market consisting of cable and satellite television services, the theory still fails to show any reasonable expectation of anticompetitive effects in the broader and economically relevant market comprising pay TV and streaming services. Any attempt to exercise pricing power in the pay TV market would be economically self-defeating, since it would likely prompt a significant portion of consumers to switch to (or start to only use) streaming services.
The Antitrust Case for the Transaction
When properly situated within the market that was actually being targeted in the AT&T/Time Warner acquisition, the combined entity posed little credible threat of exercising pricing power. To the contrary, the combined entity was best understood as an entrant that sought to challenge the two pioneer entities—Amazon and Netflix—in the “over the top” content market.
Each of these incumbent platforms individually had (and have) multi-billion-dollar content production budgets that rival or exceed the budgets of major Hollywood studios and enjoy worldwide subscriber bases numbering in the hundreds of millions. If that’s not enough, AT&T was not the only entity that observed the displacement of pay TV by streaming services, as illustrated by the roughly concurrent entry of Disney’s Disney+ service, Apple’s Apple TV+ service, Comcast NBCUniversal’s Peacock service, and others. Both the existing and new competitors are formidable entities operating in a market with formidable capital requirements. In 2019, Netflix, Amazon, and Apple TV expended approximately $15 billion, $6 billion, and again, $6 billion, respectively, on content; by contrast, HBO Max, AT&T’s streaming service, expended approximately $3.5 billion.
In short, the combined entity faced stiff competition from existing and reasonably anticipated competitors, requiring several billions of dollars on “content spend” to even stay in the running. Far from being able to exercise pricing power in an imaginary market defined by DOJ litigators for strategic purposes, the AT&T/Time Warner entity faced the challenge of merely surviving in a real-world market populated by several exceptionally well-financed competitors. At best, the combined entity “threatened” to deliver incremental competitive benefits by adding a robust new platform to the video-streaming market; at worst, it would fail in this objective and cause no incremental competitive harm. As it turns out, the latter appears to be the case.
The Enduring Virtues of Antitrust Prudence
AT&T’s M&A fiasco has important lessons for broader antitrust debates about the evidentiary standards that should be applied by courts and agencies when assessing alleged antitrust violations, in general, and vertical restraints, in particular.
Among some scholars, regulators, and legislators, it has become increasingly received wisdom that prevailing evidentiary standards, as reflected in federal case law and agency guidelines, are excessively demanding, and have purportedly induced chronic underenforcement. It has been widely asserted that the courts’ and regulators’ focus on avoiding “false positives” and the associated costs of disrupting innocuous or beneficial business practices has resulted in an overly cautious enforcement posture, especially with respect to mergers and vertical restraints.
In fact, these views were expressed by some commentators in endorsing the antitrust case against the AT&T/Time-Warner transaction. Some legislators have gone further and argued for substantial amendments to the antitrust law to provide enforcers and courts with greater latitude to block or re-engineer combinations that would not pose sufficiently demonstrated competitive risks under current statutory or case law.
The swift downfall of the AT&T/Time-Warner transaction casts great doubt on this critique and accompanying policy proposals. It was precisely the district court’s rigorous application of those “overly” demanding evidentiary standards that avoided what would have been a clear false-positive error. The failure of the “blockbuster” combination to achieve not only market dominance, but even reasonably successful entry, validates the wisdom of retaining those standards.
The fundamental mismatch between the widely supported antitrust case against the transaction and the widely overlooked business realities of the economically relevant consumer market illustrates the ease with which largely theoretical and decontextualized economic models of competitive harm can lead to enforcement actions that lack any reasonable basis in fact.

The U.S. Department of Justice’s (DOJ) antitrust case against Google, which was filed in October 2020, will be a tough slog. It is an alleged monopolization (Sherman Act, Sec. 2) case; and monopolization cases are always a tough slog.
In this brief essay I will lay out some of the issues in the case and raise an intriguing possibility.
What is the case about?
The case is about exclusivity and exclusion in the distribution of search engine services; that Google paid substantial sums to Apple and to the manufacturers of Android-based mobile phones and tablets and also to wireless carriers and web-browser proprietors—in essence, to distributors—to install the Google search engine as the exclusive pre-set (installed), default search program. The suit alleges that Google thereby made it more difficult for other search-engine providers (e.g., Bing; DuckDuckGo) to obtain distribution for their search-engine services and thus to attract search-engine users and to sell the online advertising that is associated with search-engine use and that provides the revenue to support the search “platform” in this “two-sided market” context.
Exclusion can be seen as a form of “raising rivals’ costs.” Equivalently, exclusion can be seen as a form of non-price predation. Under either interpretation, the exclusionary action impedes competition.
It’s important to note that these allegations are different from those that motivated an investigation by the Federal Trade Commission (which the FTC dropped in 2013) and the cases by the European Union against Google. Those cases focused on alleged self-preferencing; that Google was unduly favoring its own products and services (e.g., travel services) in its delivery of search results to users of its search engine. In those cases, the impairment of competition (arguably) happens with respect to those competing products and services, not with respect to search itself.
What is the relevant market?
For a monopolization allegation to have any meaning, there needs to be the exercise of market power (which would have adverse consequences for the buyers of the product). And in turn, that exercise of market power needs to occur in a relevant market: one in which market power can be exercised.
Here is one of the important places where the DOJ’s case is likely to turn into a slog: the delineation of a relevant market for alleged monopolization cases remains as a largely unsolved problem for antitrust economics. This is in sharp contrast to the issue of delineating relevant markets for the antitrust analysis of proposed mergers. For this latter category, the paradigm of the “hypothetical monopolist” and the possibility that this hypothetical monopolist could prospectively impose a “small but significant non-transitory increase in price” (SSNIP) has carried the day for the purposes of market delineation.
But no such paradigm exists for monopolization cases, in which the usual allegation is that the defendant already possesses market power and has used the exclusionary actions to buttress that market power. To see the difficulties, it is useful to recall the basic monopoly diagram from Microeconomics 101. A monopolist faces a negatively sloped demand curve for its product (at higher prices, less is bought; at lower prices, more is bought) and sets a profit-maximizing price at the level of output where its marginal revenue (MR) equals its marginal costs (MC). Its price is thereby higher than an otherwise similar competitive industry’s price for that product (to the detriment of buyers) and the monopolist earns higher profits than would the competitive industry.
But unless there are reliable benchmarks as to what the competitive price and profits would otherwise be, any information as to the defendant’s price and profits has little value with respect to whether the defendant already has market power. Also, a claim that a firm does not have market power because it faces rivals and thus isn’t able profitably to raise its price from its current level (because it would lose too many sales to those rivals) similarly has no value. Recall the monopolist from Micro 101. It doesn’t set a higher price than the one where MR=MC, because it would thereby lose too many sales to other sellers of other things.
Thus, any firm—regardless of whether it truly has market power (like the Micro 101 monopolist) or is just another competitor in a sea of competitors—should have already set its price at its profit-maximizing level and should find it unprofitable to raise its price from that level. And thus the claim, “Look at all of the firms that I compete with! I don’t have market power!” similarly has no informational value.
Let us now bring this problem back to the Google monopolization allegation: What is the relevant market? In the first instance, it has to be “the provision of answers to user search queries.” After all, this is the “space” in which the exclusion occurred. But there are categories of search: e.g., search for products/services, versus more general information searches (“What is the current time in Delaware?” “Who was the 21st President of the United States?”). Do those separate categories themselves constitute relevant markets?
Further, what would the exercise of market power in a (delineated relevant) market look like? Higher-than-competitive prices for advertising that targets search-results recipients is one obvious answer (but see below). In addition, because this is a two-sided market, the competitive “price” (or prices) might involve payments by the search engine to the search users (in return for their exposure to the lucrative attached advertising). And product quality might exhibit less variety than a competitive market would provide; and/or the monopolistic average level of quality would be lower than in a competitive market: e.g., more abuse of user data, and/or deterioration of the delivered information itself, via more self-preferencing by the search engine and more advertising-driven preferencing of results.
In addition, a natural focus for a relevant market is the advertising that accompanies the search results. But now we are at the heart of the difficulty of delineating a relevant market in a monopolization context. If the relevant market is “advertising on search engine results pages,” it seems highly likely that Google has market power. If the relevant market instead is all online U.S. advertising (of which Google’s revenue share accounted for 32% in 2019), then the case is weaker; and if the relevant market is all advertising in the United States (which is about twice the size of online advertising), the case is weaker still. Unless there is some competitive benchmark, there is no easy way to delineate the relevant market.
What exactly has Google been paying for, and why?
As many critics of the DOJ’s case have pointed out, it is extremely easy for users to switch their default search engine. If internet search were a normal good or service, this ease of switching would leave little room for the exercise of market power. But in that case, why is Google willing to pay $8-$12 billion annually for the exclusive default setting on Apple devices and large sums to the manufacturers of Android-based devices (and to wireless carriers and browser proprietors)? Why doesn’t Google instead run ads in prominent places that remind users how superior Google’s search results are and how easy it is for users (if they haven’t already done so) to switch to the Google search engine and make Google the user’s default choice?
Suppose that user inertia is important. Further suppose that users generally have difficulty in making comparisons with respect to the quality of delivered search results. If this is true, then being the default search engine on Apple and Android-based devices and on other distribution vehicles would be valuable. In this context, the inertia of their customers is a valuable “asset” of the distributors that the distributors may not be able to take advantage of, but that Google can (by providing search services and selling advertising). The question of whether Google’s taking advantage of this user inertia means that Google exercises market power takes us back to the issue of delineating the relevant market.
There is a further wrinkle to all of this. It is a well-understood concept in antitrust economics that an incumbent monopolist will be willing to pay more for the exclusive use of an essential input than a challenger would pay for access to the input. The basic idea is straightforward. By maintaining exclusive use of the input, the incumbent monopolist preserves its (large) monopoly profits. If the challenger enters, the incumbent will then earn only its share of the (much lower, more competitive) duopoly profits. Similarly, the challenger can expect only the lower duopoly profits. Accordingly, the incumbent should be willing to outbid (and thereby exclude) the challenger and preserve the incumbent’s exclusive use of the input, so as to protect those monopoly profits.
To bring this to the Google monopolization context, if Google does possess market power in some aspect of search—say, because online search-linked advertising is a relevant market—then Google will be willing to outbid Microsoft (which owns Bing) for the “asset” of default access to Apple’s (inertial) device owners. That Microsoft is a large and profitable company and could afford to match (or exceed) Google’s payments to Apple is irrelevant. If the duopoly profits for online search-linked advertising would be substantially lower than Google’s current profits, then Microsoft would not find it worthwhile to try to outbid Google for that default access asset.
Alternatively, this scenario could be wholly consistent with an absence of market power. If search users (who can easily switch) consider Bing to be a lower-quality search service, then large payments by Microsoft to outbid Google for those exclusive default rights would be largely wasted, since the “acquired” default search users would quickly switch to Google (unless Microsoft provided additional incentives for the users not to switch).
But this alternative scenario returns us to the original puzzle: Why is Google making such large payments to the distributors for those exclusive default rights?
An intriguing possibility
Consider the following possibility. Suppose that Google was paying that $8-$12 billion annually to Apple in return for the understanding that Apple would not develop its own search engine for Apple’s device users. This possibility was not raised in the DOJ’s complaint, nor is it raised in the subsequent suits by the state attorneys general.
But let’s explore the implications by going to an extreme. Suppose that Google and Apple had a formal agreement that—in return for the $8-$12 billion per year—Apple would not develop its own search engine. In this event, this agreement not to compete would likely be seen as a violation of Section 1 of the Sherman Act (which does not require a market delineation exercise) and Apple would join Google as a co-conspirator. The case would take on the flavor of the FTC’s prosecution of “pay-for-delay” agreements between the manufacturers of patented pharmaceuticals and the generic drug manufacturers that challenge those patents and then receive payments from the former in return for dropping the patent challenge and delaying the entry of the generic substitute.
As of this writing, there is no evidence of such an agreement and it seems quite unlikely that there would have been a formal agreement. But the DOJ will be able to engage in discovery and take depositions. It will be interesting to find out what the relevant executives at Google—and at Apple—thought was being achieved by those payments.
What would be a suitable remedy/relief?
The DOJ’s complaint is vague with respect to the remedy that it seeks. This is unsurprising. The DOJ may well want to wait to see how the case develops and then amend its complaint.
However, even if Google’s actions have constituted monopolization, it is difficult to conceive of a suitable and effective remedy. One apparently straightforward remedy would be to require simply that Google not be able to purchase exclusivity with respect to the pre-set default settings. In essence, the device manufacturers and others would always be able to sell parallel default rights to other search engines: on the basis, say, that the default rights for some categories of customers—or even a percentage of general customers (randomly selected)—could be sold to other search-engine providers.
But now the Gilbert-Newbery insight comes back into play. Suppose that a device manufacturer knows (or believes) that Google will pay much more if—even in the absence of any exclusivity agreement—Google ends up being the pre-set search engine for all (or nearly all) of the manufacturer’s device sales, as compared with what the manufacturer would receive if those default rights were sold to multiple search-engine providers (including, but not solely, Google). Can that manufacturer (recall that the distributors are not defendants in the case) be prevented from making this sale to Google and thus (de facto) continuing Google’s exclusivity?
Even a requirement that Google not be allowed to make any payment to the distributors for a default position may not improve the competitive environment. Google may be able to find other ways of making indirect payments to distributors in return for attaining default rights, e.g., by offering them lower rates on their online advertising.
Further, if the ultimate goal is an efficient outcome in search, it is unclear how far restrictions on Google’s bidding behavior should go. If Google were forbidden from purchasing any default installation rights for its search engine, would (inert) consumers be better off? Similarly, if a distributor were to decide independently that its customers were better served by installing the Google search engine as the default, would that not be allowed? But if it is allowed, how could one be sure that Google wasn’t indirectly paying for this “independent” decision (e.g., through favorable advertising rates)?
It’s important to remember that this (alleged) monopolization is different from the Standard Oil case of 1911 or even the (landline) AT&T case of 1984. In those cases, there were physical assets that could be separated and spun off to separate companies. For Google, physical assets aren’t important. Although it is conceivable that some of Google’s intellectual property—such as Gmail, YouTube, or Android—could be spun off to separate companies, doing so would do little to cure the (arguably) fundamental problem of the inert device users.
In addition, if there were an agreement between Google and Apple for the latter not to develop a search engine, then large fines for both parties would surely be warranted. But what next? Apple can’t be forced to develop a search engine. This differentiates such an arrangement from the “pay-for-delay” arrangements for pharmaceuticals, where the generic manufacturers can readily produce a near-identical substitute for the patented drug and are otherwise eager to do so.
At the end of the day, forbidding Google from paying for exclusivity may well be worth trying as a remedy. But as the discussion above indicates, it is unlikely to be a panacea and is likely to require considerable monitoring for effective enforcement.
The DOJ’s case against Google will be a slog. There are unresolved issues—such as how to delineate a relevant market in a monopolization case—that will be central to the case. Even if the DOJ is successful in showing that Google violated Section 2 of the Sherman Act in monopolizing search and/or search-linked advertising, an effective remedy seems problematic. But there also remains the intriguing question of why Google was willing to pay such large sums for those exclusive default installation rights?
The developments in the case will surely be interesting.
 The DOJ’s suit was joined by 11 states. More states subsequently filed two separate antitrust lawsuits against Google in December.
 There is also a related argument: That Google thereby gained greater volume, which allowed it to learn more about its search users and their behavior, and which thereby allowed it to provide better answers to users (and thus a higher-quality offering to its users) and better-targeted (higher-value) advertising to its advertisers. Conversely, Google’s search-engine rivals were deprived of that volume, with the mirror-image negative consequences for the rivals. This is just another version of the standard “learning-by-doing” and the related “learning curve” (or “experience curve”) concepts that have been well understood in economics for decades.

Scheffman, “Raising Rivals’ Costs: Recent Advances in the Theory of Industrial Structure,” American Economic Review, Vol. 73, No. 2 (May 1983), pp. 267-271; and Thomas G. Krattenmaker and Steven C. Salop, “Anticompetitive Exclusion: Raising Rivals’ Costs To Achieve Power Over Price,” Yale Law Journal, Vol. 96, No. 2 (December 1986), pp. 209-293.

 For a more complete version of the argument that follows, see Lawrence J. White, “Market Power and Market Definition in Monopolization Cases: A Paradigm Is Missing,” in Wayne D. Collins, ed., Issues in Competition Law and Policy. American Bar Association, 2008, pp. 913-924.
 The forgetting of this important point is often termed “the cellophane fallacy”, since this is what the U.S. Supreme Court did in a 1956 antitrust case in which the DOJ alleged that du Pont had monopolized the cellophane market (and du Pont, in its defense claimed that the relevant market was much wider: all flexible wrapping materials); see U.S. v. du Pont, 351 U.S. 377 (1956). For an argument that profit data and other indicia argued for cellophane as the relevant market, see George W. Stocking and Willard F. Mueller, “The Cellophane Case and the New Competition,” American Economic Review, Vol. 45, No. 1 (March 1955), pp. 29-63.
 In the context of differentiated services, one would expect prices (positive or negative) to vary according to the quality of the service that is offered. It is worth noting that Bing offers “rewards” to frequent searchers; see https://www.microsoft.com/en-us/bing/defaults-rewards. It is unclear whether this pricing structure of payment to Bing’s customers represents what a more competitive framework in search might yield, or whether the payment just indicates that search users consider Bing to be a lower-quality service.
 As an additional consequence of the impairment of competition in this type of search market, there might be less technological improvement in the search process itself – to the detriment of users.
 And, again, if we return to the du Pont cellophane case: Was the relevant market cellophane? Or all flexible wrapping materials?
 This insight is formalized in Richard J. Gilbert and David M.G. Newbery, “Preemptive Patenting and the Persistence of Monopoly,” American Economic Review, Vol. 72, No. 3 (June 1982), pp. 514-526.
 To my knowledge, Randal C. Picker was the first to suggest this possibility; see https://www.competitionpolicyinternational.com/a-first-look-at-u-s-v-google/. Whether Apple would be interested in trying to develop its own search engine – given the fiasco a decade ago when Apple tried to develop its own maps app to replace the Google maps app – is an open question. In addition, the Gilbert-Newbery insight applies here as well: Apple would be less inclined to invest the substantial resources that would be needed to develop a search engine when it is thereby in a duopoly market. But Google might be willing to pay “insurance” to reinforce any doubts that Apple might have.
 The U.S. Supreme Court, in FTC v. Actavis, 570 U.S. 136 (2013), decided that such agreements could be anti-competitive and should be judged under the “rule of reason”. For a discussion of the case and its implications, see, for example, Joseph Farrell and Mark Chicu, “Pharmaceutical Patents and Pay-for-Delay: Actavis (2013),” in John E. Kwoka, Jr., and Lawrence J. White, eds. The Antitrust Revolution: Economics, Competition, and Policy, 7th edn. Oxford University Press, 2019, pp. 331-353.
 This is an example of the insight that vertical arrangements – in this case combined with the Gilbert-Newbery effect – can be a way for dominant firms to raise rivals’ costs. See, for example, John Asker and Heski Bar-Isaac. 2014. “Raising Retailers’ Profits: On Vertical Practices and the Exclusion of Rivals.” American Economic Review, Vol. 104, No. 2 (February 2014), pp. 672-686.
 And, again, for the reasons discussed above, Apple might not be eager to make the effort.
This week the Senate will hold a hearing into potential anticompetitive conduct by Google in its display advertising business—the “stack” of products that it offers to advertisers seeking to place display ads on third-party websites. It is also widely reported that the Department of Justice is preparing a lawsuit against Google that will likely include allegations of anticompetitive behavior in this market, and is likely to be joined by a number of state attorneys general in that lawsuit. Meanwhile, several papers have been published detailing these allegations.
This aspect of digital advertising can be incredibly complex and difficult to understand. Here we explain how display advertising fits in the broader digital advertising market, describe how display advertising works, consider the main allegations against Google, and explain why Google’s critics are misguided to focus on antitrust as a solution to alleged problems in the market (even if those allegations turn out to be correct).
Display advertising in context
Over the past decade, the price of advertising has fallen steadily while output has risen. Spending on digital advertising in the US grew from $26 billion in 2010 to nearly $130 billion in 2019, an average increase of 20% a year. Over the same period the Producer Price Index for Internet advertising sales declined by nearly 40%. The rising spending in the face of falling prices indicates the number of ads bought and sold increased by approximately 27% a year. Since 2000, advertising spending has been falling as a share of GDP, with online advertising growing as a share of that. The combination of increasing quantity, decreasing cost, and increasing total revenues are consistent with a growing and increasingly competitive market.
Display advertising on third-party websites is only a small subsection of the digital advertising market, comprising approximately 15-20% of digital advertising spending in the US. The rest of the digital advertising market is made up of ads on search results pages on sites like Google, Amazon and Kayak, on people’s Instagram and Facebook feeds, listings on sites like Zillow (for houses) or Craigslist, referral fees paid to price comparison websites for things like health insurance, audio and visual ads on services like Spotify and Hulu, and sponsored content from influencers and bloggers who will promote products to their fans.
And digital advertising itself is only one of many channels through which companies can market their products. About 53% of total advertising spending in the United States goes on digital channels, with 30% going on TV advertising and the rest on things like radio ads, billboards and other more traditional forms of advertising. A few people still even read physical newspapers and the ads they contain, although physical newspapers’ bigger money makers have traditionally been classified ads, which have been replaced by less costly and more effective internet classifieds, such as those offered by Craigslist, or targeted ads on Google Maps or Facebook.
Indeed, it should be noted that advertising itself is only part of the larger marketing market of which non-advertising marketing communication—e.g., events, sales promotion, direct marketing, telemarketing, product placement—is as big a part as is advertising (each is roughly $500bn globally); it just hasn’t been as thoroughly disrupted by the Internet yet. But it is a mistake to assume that digital advertising is not a part of this broader market. And of that $1tr global market, Internet advertising in total occupies only about 18%—and thus display advertising only about 3%.
Ad placement is only one part of the cost of digital advertising. An advertiser trying to persuade people to buy its product must also do market research and analytics to find out who its target market is and what they want. Moreover, there are the costs of designing and managing a marketing campaign and additional costs to analyze and evaluate the effectiveness of the campaign.
Nevertheless, one of the most straightforward ways to earn money from a website is to show ads to readers alongside the publisher’s content. To satisfy publishers’ demand for advertising revenues, many services have arisen to automate and simplify the placement of and payment for ad space on publishers’ websites. Google plays a large role in providing these services—what is referred to as “open display” advertising. And it is Google’s substantial role in this space that has sparked speculation and concern among antitrust watchdogs and enforcement authorities.
Before delving into the open display advertising market, a quick note about terms. In these discussions, “advertisers” are businesses that are trying to sell people stuff. Advertisers include large firms such as Best Buy and Disney and small businesses like the local plumber or financial adviser. “Publishers” are websites that carry those ads, and publish content that users want to read. Note that the term “publisher” refers to all websites regardless of the things they’re carrying: a blog about the best way to clean stains out of household appliances is a “publisher” just as much as the New York Times is.
Under this broad definition, Facebook, Instagram, and YouTube are also considered publishers. In their role as publishers, they have a common goal: to provide content that attracts users to their pages who will act on the advertising displayed. “Users” are you and me—the people who want to read publishers’ content, and to whom advertisers want to show ads. Finally, “intermediaries” are the digital businesses, like Google, that sit in between the advertisers and the publishers, allowing them to do business with each other without ever meeting or speaking.
The display advertising market
If you’re an advertiser, display advertising works like this: your company—one that sells shoes, let’s say—wants to reach a certain kind of person and tell her about the company’s shoes. These shoes are comfortable, stylish, and inexpensive. You use a tool like Google Ads (or, if it’s a big company and you want a more expansive campaign over which you have more control, Google Marketing Platform) to design and upload an ad, and tell Google about the people you want to read—their age and location, say, and/or characterizations of their past browsing and searching habits (“interested in sports”).
Using that information, Google finds ad space on websites whose audiences match the people you want to target. This ad space is auctioned off to the highest bidder among the range of companies vying, with your shoe company, to reach users matching the characteristics of the website’s users. Thanks to tracking data, it doesn’t just have to be sports-relevant websites: as a user browses sports-related sites on the web, her browser picks up files (cookies) that will tag her as someone potentially interested in sports apparel for targeting later.
So a user might look at a sports website and then later go to a recipe blog, and there receive the shoes ad on the basis of her earlier browsing. You, the shoe seller, hope that she will either click through and buy (or at least consider buying) the shoes when she sees those ads, but one of the benefits of display advertising over search advertising is that—as with TV ads or billboard ads—just seeing the ad will make her aware of the product and potentially more likely to buy it later. Advertisers thus sometimes pay on the basis of clicks, sometimes on the basis of views, and sometimes on the basis of conversion (when a consumer takes an action of some sort, such as making a purchase or filling out a form).
That’s the advertiser’s perspective. From the publisher’s perspective—the owner of that recipe blog, let’s say—you want to auction ad space off to advertisers like that shoe company. In that case, you go to an ad server—Google’s product is called AdSense—give them a little bit of information about your site, and add some html code to your website. These ad servers gather information about your content (e.g., by looking at keywords you use) and your readers (e.g., by looking at what websites they’ve used in the past to make guesses about what they’ll be interested in) and places relevant ads next to and among your content. If they click, lucky you—you’ll get paid a few cents or dollars.
Apart from privacy concerns about the tracking of users, the really tricky and controversial part here concerns the way scarce advertising space is allocated. Most of the time, it’s done through auctions that happen in real time: each time a user loads a website, an auction is held in a fraction of a second to decide which advertiser gets to display an ad. The longer this process takes, the slower pages load and the more likely users are to get frustrated and go somewhere else.
As well as the service hosting the auction, there are lots of little functions that different companies perform that make the auction and placement process smoother. Some fear that by offering a very popular product integrated end to end, Google’s “stack” of advertising products can bias auctions in favour of its own products. There’s also speculation that Google’s product is so tightly integrated and so effective at using data to match users and advertisers that it is not viable for smaller rivals to compete.
We’ll discuss this speculation and fear in more detail below. But it’s worth bearing in mind that this kind of real-time bidding for ad placement was not always the norm, and is not the only way that websites display ads to their users even today. Big advertisers and websites often deal with each other directly. As with, say, TV advertising, large companies advertising often have a good idea about the people they want to reach. And big publishers (like popular news websites) often have a good idea about who their readers are. For example, big brands often want to push a message to a large number of people across different customer types as part of a broader ad campaign.
Of these kinds of direct sales, sometimes the space is bought outright, in advance, and reserved for those advertisers. In most cases, direct sales are run through limited, intermediated auction services that are not open to the general market. Put together, these kinds of direct ad buys account for close to 70% of total US display advertising spending. The remainder—the stuff that’s left over after these kinds of sales have been done—is typically sold through the real-time, open display auctions described above.
Different adtech products compete on their ability to target customers effectively, to serve ads quickly (since any delay in the auction and ad placement process slows down page load times for users), and to do so inexpensively. All else equal (including the effectiveness of the ad placement), advertisers want to pay the lowest possible price to place an ad. Similarly, publishers want to receive the highest possible price to display an ad. As a result, both advertisers and publishers have a keen interest in reducing the intermediary’s “take” of the ad spending.
This is all a simplification of how the market works. There is not one single auction house for ad space—in practice, many advertisers and publishers end up having to use lots of different auctions to find the best price. As the market evolved to reach this state from the early days of direct ad buys, new functions that added efficiency to the market emerged.
In the early years of ad display auctions, individual processes in the stack were performed by numerous competing companies. Through a process of “vertical integration” some companies, such as Google, brought these different processes under the same roof, with the expectation that integration would streamline the stack and make the selling and placement of ads more efficient and effective. The process of vertical integration in pursuit of efficiency has led to a more consolidated market in which Google is the largest player, offering simple, integrated ad buying products to advertisers and ad selling products to publishers.
Google is by no means the only integrated adtech service provider, however: Facebook, Amazon, Verizon, AT&T/Xandr, theTradeDesk, LumenAd, Taboola and others also provide end-to-end adtech services. But, in the market for open auction placement on third-party websites, Google is the biggest.
The cases against Google
The UK’s Competition and Markets Authority (CMA) carried out a formal study into the digital advertising market between 2019 and 2020, issuing its final report in July of this year. Although also encompassing Google’s Search advertising business and Facebook’s display advertising business (both of which relate to ads on those companies “owned and operated” websites and apps), the CMA study involved the most detailed independent review of Google’s open display advertising business to date.
That study did not lead to any competition enforcement proceedings, but it did conclude that Google’s vertically integrated products led to conflicts of interest that could lead it to behaving in ways that did not benefit the advertisers and publishers that use it. One example was Google’s withholding of certain data from publishers that would make it easier for them to use other ad selling products; another was the practice of setting price floors that allegedly led advertisers to pay more than they would otherwise.
Instead the CMA recommended the setting up of a “Digital Markets Unit” (DMU) that could regulate digital markets in general, and a code of conduct for Google and Facebook (and perhaps other large tech platforms) intended to govern their dealings with smaller customers.
The CMA’s analysis is flawed, however. For instance, it makes big assumptions about the dependency of advertisers on display advertising, largely assuming that they would not switch to other forms of advertising if prices rose, and it is light on economics. But factually it is the most comprehensively researched investigation into digital advertising yet published.
While the Scott Morton and Dinielli paper is extremely broad, it also suffers from a number of problems.
One, because it was released before the CMA’s final report, it is largely based on the interim report released months earlier by the CMA, halfway through the market study in December 2019. This means that several of its claims are out of date. For example, it makes much of the possibility raised by the CMA in its interim report that Google may take a larger cut of advertising spending than its competitors, and claims made in another report that Google introduces “hidden” fees that increases the overall cut it takes from ad auctions.
But in the final report, after further investigation, the CMA concludes that this is not the case. In the final report, the CMA describes its analysis of all Google Ad Manager open auctions related to UK web traffic during the period between 8–14 March 2020 (involving billions of auctions). This, according to the CMA, allowed it to observe any possible “hidden” fees as well. The CMA concludes:
Our analysis found that, in transactions where both Google Ads and Ad Manager (AdX) are used, Google’s overall take rate is approximately 30% of advertisers’ spend. This is broadly in line with (or slightly lower than) our aggregate market-wide fee estimate outlined above. We also calculated the margin between the winning bid and the second highest bid in AdX for Google and non-Google DSPs, to test whether Google was systematically able to win with a lower margin over the second highest bid (which might have indicated that they were able to use their data advantage to extract additional hidden fees). We found that Google’s average winning margin was similar to that of non-Google DSPs. Overall, this evidence does not indicate that Google is currently extracting significant hidden fees. As noted below, however, it retains the ability and incentive to do so. (p. 275, emphasis added)
Scott Morton and Dinielli also misquote and/or misunderstand important sections of the CMA interim report as relating to display advertising when, in fact, they relate to search. For example, Scott Morton and Dinielli write that the “CMA concluded that Google has nearly insurmountable advantages in access to location data, due to the location information [uniquely available to it from other sources].” (p. 15). The CMA never makes any claim of “insurmountable advantage,” however. Rather, to support the claim, Scott Morton and Dinielli cite to a portion of the CMA interim report recounting a suggestion made by Microsoft regarding the “critical” value of location data in providing relevant advertising.
But that portion of the report, as well as the suggestion made by Microsoft, is about search advertising. While location data may also be valuable for display advertising, it is not clear that the GPS-level data that is so valuable in providing mobile search ad listings (for a nearby cafe or restaurant, say) is particularly useful for display advertising, which may be just as well-targeted by less granular, city- or county-level location data, which is readily available from a number of sources. In any case, Scott Morton and Dinielli are simply wrong to use a suggestion offered by Microsoft relating to search advertising to demonstrate the veracity of an assertion about a conclusion drawn by the CMA regarding display advertising.
Scott Morton and Dinielli also confusingly word their own judgements about Google’s conduct in ways that could be misinterpreted as conclusions by the CMA:
The CMA reports that Google has implemented an anticompetitive sales strategy on the publisher ad server end of the intermediation chain. Specifically, after purchasing DoubleClick, which became its publisher ad server, Google apparently lowered its prices to publishers by a factor of ten, at least according to one publisher’s account related to the CMA. (p. 20)
In fact, the CMA does not conclude that Google lowering its prices was an “anticompetitive sales strategy”—it does not use these words at all—and what Scott Morton and Dinielli are referring to is a claim by a rival ad server business, Smart, that Google cutting its prices after acquiring Doubleclick led to Google expanding its market share. Apart from the misleading wording, it is unclear why a competition authority should consider it to be “anticompetitive” when prices are falling and kept low, and—as Smart reported to the CMA—its competitor’s response is to enhance its own offering.
The case that remains
Stripping away the elements of Scott Morton and Dinielli’s case that seem unsubstantiated by a more careful reading of the CMA reports, and with the benefit of the findings in the CMA’s final report, we are left with a case that argues that Google self-preferences to an unreasonable extent, giving itself a product that is as successful as it is in display advertising only because of Google’s unique ability to gain advantage from its other products that have little to do with display advertising. Because of this self-preferencing, they might argue, innovative new entrants cannot compete on an equal footing, so the market loses out on incremental competition because of the advantages Google gets from being the world’s biggest search company, owning YouTube, running Google Maps and Google Cloud, and so on.
The most significant examples of this are Google’s use of data from other products—like location data from Maps or viewing history from YouTube—to target ads more effectively; its ability to enable advertisers placing search ads to easily place display ads through the same interface; its introduction of faster and more efficient auction processes that sidestep the existing tools developed by other third-party ad exchanges; and its design of its own tool (“open bidding”) for aggregating auction bids for advertising space to compete with (rather than incorporate) an alternative tool (“header bidding”) that is arguably faster, but costs more money to use.
These allegations require detailed consideration, and in a future paper we will attempt to assess them in detail. But in thinking about them now it may be useful to consider the remedies that could be imposed to address them, assuming they do diminish the ability of rivals to compete with Google: what possible interventions we could make in order to make the market work better for advertisers, publishers, and users.
We can think of remedies as falling into two broad buckets: remedies that stop Google from doing things that improve the quality of its own offerings, thus making it harder for others to keep up; and remedies that require it to help rivals improve their products in ways otherwise accessible only to Google (e.g., by making Google’s products interoperable with third-party services) without inherently diminishing the quality of Google’s own products.
The first camp of these, what we might call “status quo minus,” includes rules banning Google from using data from its other products or offering single order forms for advertisers, or, in the extreme, a structural remedy that “breaks up” Google by either forcing it to sell off its display ad business altogether or to sell off elements of it.
What is striking about these kinds of interventions is that all of them “work” by making Google worse for those that use it. Restrictions on Google’s ability to use data from other products, for example, will make its service more expensive and less effective for those who use it. Ads will be less well-targeted and therefore less effective. This will lead to lower bids from advertisers. Lower ad prices will be transmitted through the auction process to produce lower payments for publishers. Reduced publisher revenues will mean some content providers exit. Users will thus be confronted with less available content and ads that are less relevant to them and thus, presumably, more annoying. In other words: No one will be better off, and most likely everyone will be worse off.
The reason a “single order form” helps Google is that it is useful to advertisers, the same way it’s useful to be able to buy all your groceries at one store instead of lots of different ones. Similarly, vertical integration in the “ad stack” allows for a faster, cheaper, and simpler product for users on all sides of the market. A different kind of integration that has been criticized by others, where third-party intermediaries can bid more quickly if they host on Google Cloud, benefits publishers and users because it speeds up auction time, allowing websites to load faster. So does Google’s unified alternative to “header bidding,” giving a speed boost that is apparently valuable enough to publishers that they will pay for it.
So who would benefit from stopping Google from doing these things, or even forcing Google to sell its operations in this area? Not advertisers or publishers. Maybe Google’s rival ad intermediaries would; presumably, artificially hamstringing Google’s products would make it easier for them to compete with Google. But if so, it’s difficult to see how this would be an overall improvement. It is even harder to see how this would improve the competitive process—the very goal of antitrust. Rather, any increase in the competitiveness of rivals would result not from making their products better, but from making Google’s product worse. That is a weakening of competition, not its promotion.
On the other hand, interventions that aim to make Google’s products more interoperable at least do not fall prey to this problem. Such “status quo plus” interventions would aim to take the benefits of Google’s products and innovations and allow more companies to use them to improve their own competing products. Not surprisingly, such interventions would be more in line with the conclusions the CMA came to than the divestitures and operating restrictions proposed by Scott Morton and Dinielli, as well as (reportedly) state attorneys general considering a case against Google.
But mandated interoperability raises a host of different concerns: extensive and uncertain rulemaking, ongoing regulatory oversight, and, likely, price controls, all of which would limit Google’s ability to experiment with and improve its products. The history of such mandated duties to deal or compulsory licenses is a troubled one, at best. But even if, for the sake of argument, we concluded that these kinds of remedies were desirable, they are difficult to impose via an antitrust lawsuit of the kind that the Department of Justice is expected to launch. Most importantly, if the conclusion of Google’s critics is that Google’s main offense is offering a product that is just too good to compete with without regulating it like a utility, with all the costs to innovation that that would entail, maybe we ought to think twice about whether an antitrust intervention is really worth it at all.
The goal of US antitrust law is to ensure that competition continues to produce positive results for consumers and the economy in general. We published a letter co-signed by twenty three of the U.S.’s leading economists, legal scholars and practitioners, including one winner of the Nobel Prize in economics (full list of signatories here), to exactly that effect urging the House Judiciary Committee on the State of Antitrust Law to reject calls for radical upheaval of antitrust law that would, among other things, undermine the independence and neutrality of US antitrust law.
A critical part of maintaining independence and neutrality in the administration of antitrust is ensuring that it is insulated from politics. Unfortunately, this view is under attack from all sides. The President sees widespread misconduct among US tech firms that he believes are controlled by the “radical left” and is, apparently, happy to use whatever tools are at hand to chasten them.
Meanwhile, Senator Klobuchar has claimed, without any real evidence, that the mooted Uber/Grubhub merger is simply about monopolisation of the market, and not, for example, related to the huge changes that businesses like this are facing because of the Covid shutdown.
Both of these statements challenge the principle that the rule of law depends on being politically neutral, including in antitrust.
Our letter, contrary to the claims made by President Trump, Sen. Klobuchar and some of the claims made to the Committee, asserts that the evidence and economic theory is clear: existing antitrust law is doing a good job of promoting competition and consumer welfare in digital markets and the economy more broadly, and concludes that the Committee should focus on reforms that improve antitrust at the margin, not changes that throw out decades of practice and precedent.
The letter argues that:
The American economy—including the digital sector—is competitive, innovative, and serves consumers well, contrary to how it is sometimes portrayed in the public debate.
Structural changes in the economy have resulted from increased competition, and increases in national concentration have generally happened because competition at the local level has intensified and local concentration has fallen.
Lax antitrust enforcement has not allowed systematic increases in market power, and the evidence simply does not support out the idea that antitrust enforcement has weakened in recent decades.
Existing antitrust law is adequate for protecting competition in the modern economy, and built up through years of careful case-by-case scrutiny. Calls to throw out decades of precedent to achieve an antitrust “Year Zero” would throw away a huge body of learning and deliberation.
History teaches that discarding the modern approach to antitrust would harm consumers, and return to a situation where per se rules prohibited the use of economic analysis and fact-based defences of business practices.
Common sense reforms should be pursued to improve antitrust enforcement, and the reforms proposed in the letter could help to improve competition and consumer outcomes in the United States without overturning the whole system.
The reforms suggested include measures to increase transparency of the DoJ and FTC, greater scope for antitrust challenges against state-sponsored monopolies, stronger penalties for criminal cartel conduct, and more agency resources being made available to protect workers from anti-competitive wage-fixing agreements between businesses. These are suggestions for the House Committee to consider and are not supported by all the letter’s signatories.
Some of the arguments in the letter are set out in greater detail in the ICLE’s own submission to the Committee, which goes into detail about the nature of competition in modern digital markets and in traditional markets that have been changed because of the adoption of digital technologies.

The antitrust laws have not been suspended during the current COVID-19 crisis. But based on questions received from clients plus others discussed with other practitioners, the changed economic conditions have raised some new questions and put a new slant on some old ones.
Under antitrust law’s flexible rule of reason standard, courts and enforcers consider the competitive effect of most actions under current and expected economic conditions. Because those conditions have changed drastically, at least temporarily, perhaps the antitrust assessments of certain actions will be different. Also, in a crisis, good businesses consider new options and reconsider others that had been rejected under the old conditions. So antitrust practitioners and enforcers need to be prepared for new questions and reconsiderations of others under new facts. Here are some that might cross their desks.
Benchmarking had its antitrust moment a few years ago as practitioners discovered and began to worry about this form of communication with competitors. Both before and since then, the comparison of processes and metrics to industry bests to determine where improvement efforts should be concentrated has not raised serious antitrust issues – if done properly. Appropriate topic choice and implementation, often involving counsel review and third-party collection, should stay the same during this crisis. Companies implementing new processes might be tempted to reach out to competitors to learn best practices. Any of those companies unfamiliar with the right way to benchmark should get up to speed. Counsel must be prepared to help clients quickly, but properly, benchmark some suddenly important activities, like methods for deep-cleaning workplaces.
Joint ventures where competitors work together to accomplish a task that neither could alone, or accomplish it more efficiently, have always received a receptive antitrust review. Often, those joint efforts have been temporary. Properly structured ones have always required the companies to remain competitors outside the joint venture. Joint efforts among competitors that did not make sense before the crisis might make perfect sense during it. For instance, a company whose distribution warehouse has been shut down by a shelter in place order might be able to use a competitor’s distribution assets to continue to get goods to the market.
Some joint ventures of competitors have received special antitrust assurances for decades. The National Cooperative Research and Production Act of 1993 was originally passed in 1984 to protect research joint ventures of competitors. It was later extended to certain joint production efforts and standard development organizations. The law confirms that certain joint ventures of competitors will be judged under the rule of reason. If the parties file a very short notice with the DOJ Antitrust Division and FTC, they also will receive favorable treatment regarding damages and attorney’s fees in any antitrust lawsuit. For example, competitors cooperating on the development of new virus treatments might be able to use NCRPA to protect joint research and even production of the cure.
Horizontal mergers that permanently combine the assets of two competitors are unlikely to be justified under the antitrust laws by small transitory blips in the economic landscape. A huge crisis, however, might be so large and create such long-lasting effects that certain mergers suddenly might make sense, both on business and antitrust grounds. That rationale was used during the most recent economic crisis to justify several large mergers of banks although other large industrial mergers considered at the same time were abandoned for various reasons. It is not yet clear if that reasoning is present in any industry now.
Remote communication among competitors
On a much smaller but more immediate scale, the new forms of communication being used while so many of us are physically separated have raised questions about the usual antitrust advice regarding communication with competitors. Antitrust practitioners have long advised clients about how to prepare and conduct an in-person meeting of competitors, say at a trade association convention. That same advice would seem to apply if, with the in-person convention cancelled, the meeting will be held via Teams or Zoom. And don’t forget: The reminders that the same rules apply to the cocktail party at the bar after the meeting should also be given for the virtual version conducted via Remo.co.
While antitrust law is focused on actions by private parties that might prevent markets from properly working to serve consumers, the same rationales apply to unnecessary government interference in the market. The current health crisis has turned the spotlight back on certificate of need laws, a form of “brother may I?” government regulation that can allow current competitors to stifle entry by new competitors. Similarly, regulations that have slowed the use of telemedicine have been at least temporarily waived.
Solving the current health crisis and rebuilding the economy will take the best efforts of both our public institutions and private companies. Antitrust law as currently written and enforced can and should continue to play a role in aligning incentives so we need not rely on “the benevolence of the butcher” for our dinner and other necessities. Instead, proper application of antitrust law can allow companies to do their part to (reviving a slogan helpful in a prior national crisis) keep America rolling.

The DOJ Antitrust Division and the FTC have issued draft proposed Vertical Merger Guidelines (VMGs). These have been long-desired in some quarters, and long-dreaded in others. The controversy remains, although those who long desired them may dread what they got, and vice versa.
I’ve accepted Geoff’s invitation to offer some short thoughts on this blessedly short draft. I’ll focus on what one might call “pure” vertical mergers, as opposed to those based on concerns regarding potential entry or expansion by a vertically integrated firm into its upstream or downstream market. After looking at what the draft classifies as unilateral effects, I’ll then turn briefly to coordinated effects, burden of proof, and the whether we want to go there at all.
A notable omission
It’s useful to think of pure vertical mergers mergers in a reverse direction; that is, not the harms they would create, but the benefits of blocking the merger even if it were harmful. The usual argument against prosecuting such mergers is that one would be left with separate firms charging above-competitive prices at one end or the other — and if they do it at both ends, creating double marginalization.
In that regard, the draft has a notable omission: a skeptical eye toward mergers when a firm with market power is unable to charge a consequently high price. The usual justification is price regulation of a monopoly. Concern about the harm of vertical integration as a means to evade such regulation was the basis for the divestiture by AT&T of its then-regulated, then-monopoly local telephone companies, the mirror image of blocking a vertical merger. This concern also formed the basis of Federal Energy Regulatory Commission orders (here and here) separating control of regulated electricity transmission lines from ownership of unregulated generation.
More controversially, one could apply this in contexts where pricing is limited by something other than explicit regulation. TOTM has recently featured a debate between Geoff Manne and Dirk Auer on one side and Mark Lemley, Doug Melamed, and Steve Salop regarding the FTC’s case against Qualcomm’s licensing practices, where the issue (I think) is about whether FRAND licensing requirements limit Qualcomm’s ability to extract the full rental value of its patents. Perhaps even more out there, I’ve suggested that transaction costs keeping Google from charging directly for search could justify concern with discrimination in favor of its offerings in other markets, without having to reject a consumer welfare standard and where “free” search could justify rather than impede an antitrust case. Whether non-regulatory restrictions on price should justify vertical concerns is, to say the least, complicated. You’ll see that word often, and I’ll come back to it at the end.
Raising rivals’ costs and foreclosure: Why would the merger matter?
The seeming truism of raising rivals’ costs is that to raise someone’s costs, you have to raise the price of an input they use or a complement they need. If a merger (or vertical restraint) extends control over an input or complement, the competitive risk arises because that complement market is being monopolized. Accordingly, enforcers need to ensure they are looking at competition and ease of entry in the market that’s being monopolized, not the market in which the bad guy who benefits might operate. For example, in the case involving Intel’s loyalty rebates to computer makers that allegedly excluded AMD’s processing chips, the relevant market was not chips but computers, and it is necessary to explain why AMD couldn’t get new computer makers to use its chips or vertically integrate itself into computers.
With a “pure” vertical merger, however, the raising rivals’ cost or foreclosure story depends not on the creation or expansion of market power over an input or complement. It must depend on how vertical integration leads to the exercise of power in that market that was not being exercised before. That requires that vertical integration changes the strategic interactions determining price and quality.
If this is the story, however, the agencies should make clear that they bear an obligation to explain how vertical integration matters, rather than assume a competitive outcome otherwise. The recent (failed) Justice Department challenge to AT&T’s vertical acquisition of Time Warner programming bears this out. DOJ’s core claim was that post-merger, Time Warner program services (HBO, CNN) would strike tougher deals with other video distributors, leading to higher licensing fees, because they would know that a failed negotiation would increase subscribership to AT&T. However, once a program service licenses to any video distributor, it realizes that if other video distributors don’t take their service, it will increase subscribers and profits from its initial deal. If that change in bargaining position benefits whoever gets the first deal, distributors presumably can cut a deal to be the first, without vertical merger being necessary.
Might vertical merger still matter? Perhaps, but plaintiffs should have to explain what transaction costs prevent such a nominally anticompetitive deal. Critics of indifference to vertical mergers, and the draft VMGs, point out that double marginalization might be eliminated without vertical integration, through use of contracts that include fixed fees and sales at marginal cost. A similar skepticism regarding the need for vertical integration to achieve anticompetitive ends is similarly appropriate. Establishing that need may be, well, complicated.
Coordination and symmetry
I have less to say about coordinated effects. Knowing when firms decide to switch from competing to cooperating is probably a matter of psychology and sociology as much as economics. However, economics does suggest that collusion is more likely the more symmetric are the positions of the potential colluders, to help find a mutually agreeable tactic and reduce the need for side payments and the like. To the extent symmetry is relevant, a pure vertical merger will facilitate collusion only if other market participants were similarly integrated. And absent market-wide collusion to integrate, this integration of the other participants could be reasonably interpreted as evidence of efficiencies of vertical integration. This would make a coordinated effects vertical merger case, well, complicated.
Contracting alternatives to vertical merger abound, as two-part pricing to eliminate double marginalization and sequential per-subscriber pricing in video markets illustrate. Absent regulation, the transaction costs necessary to create and exercise market power but for vertical integration will be lower than those necessary to create and exercise that power but for horizontal merger. This difference in transaction costs means that horizontal merger is more likely to be necessary for harm than vertical merger. Thus, proving that the latter are harmful should be, well, more complicated.
So, are pure vertical mergers worth the trouble to prosecute?
Vertical mergers might be problematic, but cases are necessarily going to be complicated. This raises the question of whether the benefits of prosecuting such mergers are worth the costs, at least outside the regulated industry context. These costs are not just the cost of litigation but the costs to companies of having to hire antitrust counsel and consultants to try to determine whether their merger is likely to be challenged, how much negotiation with the agencies will be entailed, and what the likelihood of loss in court will be. Some aspects of antitrust enforcement, primarily determining who competes with whom and how much, are inevitably complicated. But it is not clear that we are better off expending the resources to see whether something is bad, rather than accepting the cost of error from adopting imperfect rules — even rules that imply strict enforcement. Pure vertical merger may be an example of something that we might just want to leave be.
