The International Center for Law & Economics (ICLE) filed an amicus brief on behalf of itself and 26 distinguished law & economics scholars with the 9th U.S. Circuit Court of Appeals in the hotly anticipated and intensely important Epic Games v Apple case.

A fantastic group of attorneys from White & Case generously assisted us with the writing and filing of the brief, including George Paul, Jack Pace, Gina Chiapetta, and Nicholas McGuire. The scholars who signed the brief are listed at the end of this post. A summary of the brief’s arguments follows. For some of our previous writings on the case, see here, here, here, and here.

Introduction

In Epic Games v. Apple, Epic challenged Apple’s prohibition of third-party app stores and in-app payments (IAP) systems from operating on its proprietary iOS platform as a violation of antitrust law. The U.S. District Court for the Northern District of California ruled against Epic, finding that Epic’s real concern is its own business interests in the face of Apple’s business model—in particular, the commission Apple charges for use of its IAP system—rather than harm to consumers and to competition more broadly.

Epic appealed to the 9th Circuit on several grounds. Our brief primarily addresses two of Epic’s arguments:

  • First, Epic takes issue with the district court’s proper finding that Apple’s procompetitive justifications outweigh the anticompetitive effects of Apple’s business model. But Epic’s case fails at step one of the rule-of-reason analysis, as it didn’t demonstrate that Apple’s app distribution and IAP practices caused the significant, market-wide, anticompetitive effects that the Supreme Court, in 2018’s Ohio v. American Express (“Amex”), deemed necessary to show anticompetitive harm in cases involving two-sided transaction markets (like Apple’s App Store).
  • Second, Epic argues that the theoretical existence of less restrictive alternatives (“LRA”) to Apple’s business model is sufficient to meet its burden under the rule of reason. But the reliance on LRA in this case is misplaced. Forcing Apple to adopt the “open” platform that Epic champions would reduce interbrand competition and improperly permit antitrust plaintiffs to commandeer the judiciary to modify routine business conduct any time a plaintiff’s attorney or district court can imagine a less restrictive version of a challenged practice—irrespective of whether the practice promotes consumer welfare. This is especially true in the context of two-sided platform businesses, where such an approach would sacrifice interbrand, systems-level competition for the sake of a superficial increase in competition among a small subset of platform users.

Competitive Effects in Two-Sided Markets

Two-sided markets connect distinct sets of users whose demands for the platform are interdependent—i.e., consumers’ demand for a platform increases as more products are available, and conversely, product developers’ demand for a platform increases as additional consumers use the platform, increasing the overall potential for transactions. As a result of these complex dynamics, conduct that may appear anticompetitive when considering the effects on only one set of customers may be entirely consistent with—and actually promote—healthy competition when examining the effects on both sides.

That’s why the Supreme Court recognized in Amex that it was improper to focus on only one side of a two-sided platform. And this holding doesn’t require adherence to the Court’s contentious finding of a two-sided relevant market in Amex. Indeed, even scholars highly critical of the Amex decision recognize the importance of considering effects on both sides of a two-sided platform.

While the district court did find that Epic demonstrated some anticompetitive effects, Epic’s evidence focused only on the effects that Apple’s conduct had on certain app developers; it failed to appropriately examine whether consumers were harmed overall. As Geoffrey Manne has observed, in two-sided markets, “some harm” is not the same thing as “competitively relevant harm.” Supracompetitive prices on one side do not tell us much about the existence or exercise of (harmful) market power in two-sided markets. As the Supreme Court held in Amex:

The fact that two-sided platforms charge one side a price that is below or above cost reflects differences in the two sides’ demand elasticity, not market power or anticompetitive pricing. Price increases on one side of the platform likewise do not suggest anticompetitive effects without some evidence that they have increased the overall cost of the platform’s services.

Without further evidence of the effect of Apple’s practices on consumers, no conclusions can be drawn about the competitive effects of Apple’s conduct. 

Nor can an appropriate examination of anticompetitive effects ignore output. The ability to restrict output, after all, is what allows a monopolist to increase prices. Whereas price effects alone might appear predatory on one side of the market and supra-competitive on the other, output reflects what is happening in the market as a whole. It is therefore the most appropriate measure for antitrust law generally, and it is especially useful in two-sided markets, where asymmetrical price changes are of little use in determining anticompetitive effects.

Ultimately, the question before the court must be whether Apple’s overall pricing structure and business model reduces output, either by deterring app developers from participating in the market or by deterring users from purchasing apps (or iOS devices) as a consequence of the app-developer commission. The district court here noted that it could not ascertain whether Apple’s alleged restrictions had a “positive or negative impact on game transaction volume.”

Thus, Epic’s case fails at step one of the rule of reason analysis because it simply hasn’t demonstrated the requisite harm to competition.

Less Restrictive Alternatives and the Rule of Reason

But even if that weren’t the case, Epic’s claims also don’t make it past step three of the rule of reason analysis.

Epic’s appeal relies on theoretical “less restrictive alternatives” (LRA) to Apple’s business model, which highlights longstanding questions about the role and limits of LRA analysis under the rule of reason. 

According to Epic, because the district court identified some anticompetitive effects on one side of the market, and because alternative business models could, in theory, be implemented to achieve the same procompetitive benefits as Apple’s current business model, the court should have ruled in Epic’s favor at step three. 

There are several problems with this.

First, the existence of an LRA is irrelevant if anticompetitive harm has not been established, of course (as is the case here).

Nor does the fact that some hypothetically less restrictive alternative exists automatically render the conduct under consideration anticompetitive. As the Court held in Trinko, antitrust laws do not “give judges carte blanche to insist that a monopolist alter its way of doing business whenever some other approach might yield greater competition.” 

While, following the Supreme Court’s recent Alston decision, LRA analysis may well be appropriate in some contexts to identify anticompetitive conduct in the face of procompetitive justifications, there is no holding (in either the 9th Circuit or the Supreme Court) requiring it in the context of two-sided markets. (Amex refers to LRA analysis as constituting step three, but because that case was resolved at step one, it must be viewed as mere dictum).And for good reason. In the context of two-sided platforms, an LRA approach would inevitably require courts to second guess the particular allocation of costs, prices, and product attributes across platform users. As Tom Nachbar writes:

Platform defendants, even if they are able to establish the general procompetitive justifications for charging above and below cost prices on the two sides of their platforms, will have to defend the precise combination of prices they have chosen [under an LRA approach] . . . . The relative difficulty of defending any particular allocation of costs will present considerable risk of destabilizing platform markets.

Moreover, LRAs—like the ones proposed by Epic—that are based on maximizing competitor effectiveness by “opening” an incumbent’s platform would convert the rule of reason into a regulatory tool that may not promote competition at all. As Alan Devlin deftly puts it:

This construction of antitrust law—that dominant companies must affirmatively support their fringe rivals’ ability to compete effectively—adopts a perspective of antitrust that is regulatory in nature. . . . [I]f one adopts the increasingly prevalent view that antitrust must facilitate unfettered access to markets, thus spurring free entry and expansion by incumbent rivals, the Sherman Act goes from being a prophylactic device aimed at protecting consumers against welfare-reducing acts to being a misplaced regulatory tool that potentially sacrifices both consumer welfare and efficiency in a misguided pursuit of more of both.

Open Platforms Are not Necessarily Less Restrictive Platforms

It is also important to note that Epic’s claimed LRAs are neither viable alternatives nor actually “less restrictive.” Epic’s proposal would essentially turn Apple’s iOS into an open platform more similar to Google’s Android, its largest market competitor.

“Open” and “closed” platforms both have distinct benefits and drawbacks; one is not inherently superior to the other. Closed proprietary platforms like Apple’s iOS create incentives for companies to internalize positive indirect network effects, which can lead to higher levels of product variety, user adoption, and total social welfare. As Andrei Hagiu has written:

A proprietary platform may in fact induce more developer entry (i.e., product variety), user adoption and higher total social welfare than an open platform.

For example, by filtering which apps can access the App Store and precluding some transactions from taking place on it, a closed or semi-closed platform like Apple’s may ultimately increase the number of apps and transactions on its platform, where doing so makes the iOS ecosystem more attractive to both consumers and developers. 

Any analysis of a supposedly less restrictive alternative to Apple’s “walled garden” model thus needs to account for the tradeoffs between open and closed platforms, and not merely assume that “open” equates to “good,” and “closed” to “bad.” 

Further, such analysis also must consider tradeoffs among consumers and among developers. More vigilant users might be better served by an “open” platform because they find it easier to avoid harmful content; less vigilant ones may want more active assistance in screening for malware, spyware, or software that simply isn’t optimized for the user’s device. There are similar tradeoffs on the developer side: Apple’s model lowers the cost to join the App store, which particularly benefits smaller developers and those whose apps fall outside the popular gaming sector. In a nutshell, the IAP fee cross-subsidizes the delivery of services to the approximately 80% of apps on the App Store that are free and pay no IAP fees.

In fact, the overwhelming irony of Epic’s proposed approach is that Apple could avoid condemnation if it made its overall platform more restrictive. If, for example, Apple had not adopted an App Store model and offered a completely closed and fully integrated device, there would be no question of relative costs and benefits imposed on independent app developers; there would be no independent developers on the iOS platform at all. 

Thus, Epic’s proposed LRA approach, which amounts to converting iOS to an open platform, proves too much. It would enable any contractual or employment relationship for a complementary product or service to be challenged because it could be offered through a “less restrictive” open market mechanism—in other words, that any integrated firm should be converted into an open platform. 

At least since the Supreme Court’s seminal 1977 Sylvania ruling, U.S. antitrust law has been unequivocal in its preference for interbrand over intrabrand competition. Paradoxically, turning a closed platform into an open one (as Epic intends) would, under the guise of protecting competition, actually destroy competition where it matters most: at the interbrand, systems level.

Conclusion

Forcing Apple to adopt the “open” platform that Epic champions would reduce interbrand competition among platform providers. It would also more broadly allow antitrust plaintiffs to insist the courts modify routine business conduct any time a plaintiff’s attorney or district court can imagine a less restrictive version of a challenged practice, regardless of whether that practice nevertheless promotes consumer welfare. In the context of two-sided platform businesses, this would mean sacrificing systems-level competition for the sake of a superficial increase in competition among a small subset of platform users.

The bottom line is that an order compelling Apple to allow competing app stores would require the company to change the way in which it monetizes the App Store. This might have far-reaching distributional consequences for both groups— consumers and distributors. Courts (and, obviously, competitors) are ill-suited to act as social planners and to balance out such complex tradeoffs, especially in the absence of clear anticompetitive harm and the presence of plausible procompetitive benefits.

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

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

Below are 10 significant misconceptions that underpin the legislation.

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

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

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

As Geoff Manne concludes, the notion that it is harmful (notably to innovation) when platforms enter into competition with edge providers is entirely speculative. Indeed, a range of studies show that the opposite is likely true. Platform competition is more complicated than simple theories of vertical discrimination would have it, and there is certainly no basis for a presumption of harm.

Consider a few examples from the empirical literature:

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

2. Interoperability Is Not Costless

There are many things that could be interoperable, but aren’t. The reason not everything is interoperable is because interoperability comes with costs, as well as benefits. It may be worth letting different earbuds have different designs because, while it means we sacrifice easy interoperability, we gain the ability for better designs to be brought to market and for consumers to have choice among different kinds.

As Sam Bowman has observed, there are often costs that prevent interoperability from being worth the tradeoff, such as that:

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

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

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

3. Consumers Often Prefer Closed Ecosystems

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

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

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

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

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

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

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

4. Data Portability Can Undermine Security and Privacy

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

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

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

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

5. Network Effects Are Rarely Insurmountable

Several scholars in recent years have called for more muscular antitrust intervention in networked industries on grounds that network externalities, switching costs, and data-related increasing returns to scale lead to inefficient consumer lock-in and raise entry barriers for potential rivals (see here, here, and here). But there are countless counterexamples where firms have easily overcome potential barriers to entry and network externalities, ultimately disrupting incumbents.

Zoom is one of the most salient instances. As I wrote in April 2019 (a year before the COVID-19 pandemic):

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

Geoff Manne and Alec Stapp have put forward a multitude of other examples,  including: the demise of Yahoo; the disruption of early instant-messaging applications and websites; and MySpace’s rapid decline. In all of these cases, outcomes did not match the predictions of theoretical models.

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

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

6. Profits Facilitate New and Exciting Platforms

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

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

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

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

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

7. Large Market Share Does Not Mean Anticompetitive Outcomes

Scholars routinely cite the putatively strong concentration of digital markets to argue that Big Tech firms do not face strong competition. But this is a non sequitur. Indeed, as economists like Joseph Bertrand and William Baumol have shown, what matters is not whether markets are concentrated, but whether they are contestable. If a superior rival could rapidly gain user traction, that alone will discipline incumbents’ behavior.

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

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

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

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

8. Vertical Integration Generally Benefits Consumers

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

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

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

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

9. There Is No Such Thing as Data Network Effects

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

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

Critics who argue that firms such as Amazon, Google, and Facebook are successful because of their superior access to data might, in fact, have the causality in reverse. Arguably, it is because these firms have come up with successful industry-defining paradigms that they have amassed so much data, and not the other way around. Indeed, Facebook managed to build a highly successful platform despite a large data disadvantage when compared to rivals like MySpace.

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

10.  Antitrust Enforcement Has Not Been Lax

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

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

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

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

Shorter pieces

Hardly a day goes by without news of further competition-related intervention in the digital economy. The past couple of weeks alone have seen the European Commission announce various investigations into Apple’s App Store (here and here), as well as reaffirming its desire to regulate so-called “gatekeeper” platforms. Not to mention the CMA issuing its final report regarding online platforms and digital advertising.

While the limits of these initiatives have already been thoroughly dissected (e.g. here, here, here), a fundamental question seems to have eluded discussions: What are authorities trying to achieve here?

At first sight, the answer might appear to be extremely simple. Authorities want to “bring more competition” to digital markets. Furthermore, they believe that this competition will not arise spontaneously because of the underlying characteristics of digital markets (network effects, economies of scale, tipping, etc). But while it may have some intuitive appeal, this answer misses the forest for the trees.

Let us take a step back. Digital markets could have taken a vast number of shapes, so why have they systematically gravitated towards those very characteristics that authorities condemn? For instance, if market tipping and consumer lock-in are so problematic, why is it that new corners of the digital economy continue to emerge via closed platforms, as opposed to collaborative ones? Indeed, if recent commentary is to be believed, it is the latter that should succeed because they purportedly produce greater gains from trade. And if consumers and platforms cannot realize these gains by themselves, then we should see intermediaries step into the breach – i.e. arbitrage. This does not seem to be happening in the digital economy. The naïve answer is to say that this is precisely the problem, the harder one is to actually understand why.

To draw a parallel with evolution, in the late 18th century, botanists discovered an orchid with an unusually long spur (above). This made its nectar incredibly hard to reach for insects. Rational observers at the time could be forgiven for thinking that this plant made no sense, that its design was suboptimal. And yet, decades later, Darwin conjectured that the plant could be explained by a (yet to be discovered) species of moth with a proboscis that was long enough to reach the orchid’s nectar. Decades after his death, the discovery of the xanthopan moth proved him right.

Returning to the digital economy, we thus need to ask why the platform business models that authorities desire are not the ones that emerge organically. Unfortunately, this complex question is mostly overlooked by policymakers and commentators alike.

Competition law on a spectrum

To understand the above point, let me start with an assumption: the digital platforms that have been subject to recent competition cases and investigations can all be classified along two (overlapping) dimensions: the extent to which they are open (or closed) to “rivals” and the extent to which their assets are propertized (as opposed to them being shared). This distinction borrows heavily from Jonathan Barnett’s work on the topic. I believe that by applying such a classification, we would obtain a graph that looks something like this:

While these classifications are certainly not airtight, this would be my reasoning:

In the top-left quadrant, Apple and Microsoft, both operate closed platforms that are highly propertized (Apple’s platform is likely even more closed than Microsoft’s Windows ever was). Both firms notably control who is allowed on their platform and how they can interact with users. Apple notably vets the apps that are available on its App Store and influences how payments can take place. Microsoft famously restricted OEMs freedom to distribute Windows PCs as they saw fit (notably by “imposing” certain default apps and, arguably, limiting the compatibility of Microsoft systems with servers running other OSs). 

In the top right quadrant, the business models of Amazon and Qualcomm are much more “open”, yet they remain highly propertized. Almost anyone is free to implement Qualcomm’s IP – so long as they conclude a license agreement to do so. Likewise, there are very few limits on the goods that can be sold on Amazon’s platform, but Amazon does, almost by definition, exert a significant control on the way in which the platform is monetized. Retailers can notably pay Amazon for product placement, fulfilment services, etc. 

Finally, Google Search and Android sit in the bottom left corner. Both of these services are weakly propertized. The Android source code is shared freely via an open source license, and Google’s apps can be preloaded by OEMs free of charge. The only limit is that Google partially closes its platform, notably by requiring that its own apps (if they are pre-installed) receive favorable placement. Likewise, Google’s search engine is only partially “open”. While any website can be listed on the search engine, Google selects a number of specialized results that are presented more prominently than organic search results (weather information, maps, etc). There is also some amount of propertization, namely that Google sells the best “real estate” via ad placement. 

Enforcement

Readers might ask what is the point of this classification? The answer is that in each of the above cases, competition intervention attempted (or is attempting) to move firms/platforms towards more openness and less propertization – the opposite of their original design.

The Microsoft cases and the Apple investigation, both sought/seek to bring more openness and less propetization to these respective platforms. Microsoft was made to share proprietary data with third parties (less propertization) and open up its platform to rival media players and web browsers (more openness). The same applies to Apple. Available information suggests that the Commission is seeking to limit the fees that Apple can extract from downstream rivals (less propertization), as well as ensuring that it cannot exclude rival mobile payment solutions from its platform (more openness).

The various cases that were brought by EU and US authorities against Qualcomm broadly sought to limit the extent to which it was monetizing its intellectual property. The European Amazon investigation centers on the way in which the company uses data from third-party sellers (and ultimately the distribution of revenue between them and Amazon). In both of these cases, authorities are ultimately trying to limit the extent to which these firms propertize their assets.

Finally, both of the Google cases, in the EU, sought to bring more openness to the company’s main platform. The Google Shopping decision sanctioned Google for purportedly placing its services more favorably than those of its rivals. And the Android decision notably sought to facilitate rival search engines’ and browsers’ access to the Android ecosystem. The same appears to be true of ongoing investigations in the US.

What is striking about these decisions/investigations is that authorities are pushing back against the distinguishing features of the platforms they are investigating. Closed -or relatively closed- platforms are being opened-up, and firms with highly propertized assets are made to share them (or, at the very least, monetize them less aggressively).

The empty quadrant

All of this would not be very interesting if it weren’t for a final piece of the puzzle: the model of open and shared platforms that authorities apparently favor has traditionally struggled to gain traction with consumers. Indeed, there seem to be very few successful consumer-oriented products and services in this space.

There have been numerous attempts to introduce truly open consumer-oriented operating systems – both in the mobile and desktop segments. For the most part, these have ended in failure. Ubuntu and other Linux distributions remain fringe products. There have been attempts to create open-source search engines, again they have not been met with success. The picture is similar in the online retail space. Amazon appears to have beaten eBay despite the latter being more open and less propertized – Amazon has historically charged higher fees than eBay and offers sellers much less freedom in the way they sell their goods. This theme is repeated in the standardization space. There have been innumerable attempts to impose open royalty-free standards. At least in the mobile internet industry, few if any of these have taken off (5G and WiFi are the best examples of this trend). That pattern is repeated in other highly-standardized industries, like digital video formats. Most recently, the proprietary Dolby Vision format seems to be winning the war against the open HDR10+ format. 

This is not to say there haven’t been any successful ventures in this space – the internet, blockchain and Wikipedia all spring to mind – or that we will not see more decentralized goods in the future. But by and large firms and consumers have not yet taken to the idea of open and shared platforms. And while some “open” projects have achieved tremendous scale, the consumer-facing side of these platforms is often dominated by intermediaries that opt for much more traditional business models (think of Coinbase and Blockchain, or Android and Linux).

An evolutionary explanation?

The preceding paragraphs have posited a recurring reality: the digital platforms that competition authorities are trying to to bring about are fundamentally different from those that emerge organically. This begs the question: why have authorities’ ideal platforms, so far, failed to achieve truly meaningful success at consumers’ end of the market? 

I can see at least three potential explanations:

  1. Closed/propertized platforms have systematically -and perhaps anticompetitively- thwarted their open/shared rivals;
  2. Shared platforms have failed to emerge because they are much harder to monetize (and there is thus less incentive to invest in them);
  3. Consumers have opted for closed systems precisely because they are closed.

I will not go into details over the merits of the first conjecture. Current antitrust debates have endlessly rehashed this proposition. However, it is worth mentioning that many of today’s dominant platforms overcame open/shared rivals well before they achieved their current size (Unix is older than Windows, Linux is older than iOs, eBay and Amazon are basically the same age, etc). It is thus difficult to make the case that the early success of their business models was down to anticompetitive behavior.

Much more interesting is the fact that options (2) and (3) are almost systematically overlooked – especially by antitrust authorities. And yet, if true, both of them would strongly cut against current efforts to regulate digital platforms and ramp-up antitrust enforcement against them. 

For a start, it is not unreasonable to suggest that highly propertized platforms are generally easier to monetize than shared ones (2). For example, open-source platforms often rely on complementarities for monetization, but this tends to be vulnerable to outside competition and free-riding. If this is true, then there is a natural incentive for firms to invest and innovate in more propertized environments. In turn, competition enforcement that limits a platforms’ ability to propertize their assets may harm innovation.

Similarly, authorities should at the very least reflect on whether consumers really want the more “competitive” ecosystems that they are trying to design (3)

For instance, it is striking that the European Commission has a long track record of seeking to open-up digital platforms (the Microsoft decisions are perhaps the most salient example). And yet, even after these interventions, new firms have kept on using the very business model that the Commission reprimanded. Apple tied the Safari browser to its iPhones, Google went to some length to ensure that Chrome was preloaded on devices, Samsung phones come with Samsung Internet as default. But this has not deterred consumers. A sizable share of them notably opted for Apple’s iPhone, which is even more centrally curated than Microsoft Windows ever was (and the same is true of Apple’s MacOS). 

Finally, it is worth noting that the remedies imposed by competition authorities are anything but unmitigated successes. Windows XP N (the version of Windows that came without Windows Media Player) was an unprecedented flop – it sold a paltry 1,787 copies. Likewise, the internet browser ballot box imposed by the Commission was so irrelevant to consumers that it took months for authorities to notice that Microsoft had removed it, in violation of the Commission’s decision. 

There are many reasons why consumers might prefer “closed” systems – even when they have to pay a premium for them. Take the example of app stores. Maintaining some control over the apps that can access the store notably enables platforms to easily weed out bad players. Similarly, controlling the hardware resources that each app can use may greatly improve device performance. In other words, centralized platforms can eliminate negative externalities that “bad” apps impose on rival apps and consumers. This is especially true when consumers struggle to attribute dips in performance to an individual app, rather than the overall platform. 

It is also conceivable that consumers prefer to make many of their decisions at the inter-platform level, rather than within each platform. In simple terms, users arguably make their most important decision when they choose between an Apple or Android smartphone (or a Mac and a PC, etc.). In doing so, they can select their preferred app suite with one simple decision. They might thus purchase an iPhone because they like the secure App Store, or an Android smartphone because they like the Chrome Browser and Google Search. Furthermore, forcing too many “within-platform” choices upon users may undermine a product’s attractiveness. Indeed, it is difficult to create a high-quality reputation if each user’s experience is fundamentally different. In short, contrary to what antitrust authorities seem to believe, closed platforms might be giving most users exactly what they desire. 

To conclude, consumers and firms appear to gravitate towards both closed and highly propertized platforms, the opposite of what the Commission and many other competition authorities favor. The reasons for this trend are still misunderstood, and mostly ignored. Too often, it is simply assumed that consumers benefit from more openness, and that shared/open platforms are the natural order of things. This post certainly does not purport to answer the complex question of “the origin of platforms”, but it does suggest that what some refer to as “market failures” may in fact be features that explain the rapid emergence of the digital economy. Ronald Coase said this best when he quipped that economists always find a monopoly explanation for things that they fail to understand. The digital economy might just be the latest in this unfortunate trend.
