Abstract

Sherlocking refers to an online platform’s use of nonpublic third-party business data to improve its own business decisions—for instance, by mimicking the successful products and services of edge providers. Such a strategy emerges as a form of self-preferencing and, as with other theories about preferential access to data, it has been targeted by some policymakers and competition authorities due to the perceived competitive risks originating from the dual role played by hybrid platforms (acting as both referees governing their platforms, and players competing with the business they host). This paper investigates the competitive implications of sherlocking, maintaining that an outright ban is unjustified. First, the paper shows that, by aiming to ensure platform neutrality, such a prohibition would cover scenarios (i.e., the use of nonpublic third-party business data to calibrate business decisions in general, rather than to adopt a pure copycat strategy) that should be analyzed separately. Indeed, in these scenarios, sherlocking may affect different forms of competition (inter-platform v. intra-platform competition). Second, the paper argues that, in either case, the practice’s anticompetitive effects are questionable and that the ban is fundamentally driven by a bias against hybrid and vertically integrated players.

I. Introduction

The dual role some large digital platforms play (as both intermediary and trader) has gained prominence among the economic arguments used to justify the recent wave of regulation hitting digital markets around the world. Many policymakers have expressed concern about potential conflicts of interest among companies that have adopted this hybrid model and that also control important gateways for business users. In other words, the argument goes, some online firms act not only as regulators who set their platforms’ rules and as referees who enforce those rules, but also as market players who compete with their business users. This raises the fear that large platforms could reserve preferential treatment for their own services and products, to the detriment of downstream rivals and consumers. That, in turn, has led to calls for platform-neutrality rules.

Toward this aim, essentially all of the legislative initiatives undertaken around the world in recent years to enhance competition in digital markets have included anti-discrimination provisions that target various forms of self-preferencing. Self-preferencing, it has been said, serves as the symbol of the current competition-policy zeitgeist in digital markets.[1] Indeed, this conduct is considered functional to leveraging strategies that would grant gatekeepers the chance to entrench their power in core markets and extend it into associated markets.[2]

Against this background, so-called “sherlocking” has emerged as one form of self-preferencing. The term was coined roughly 20 years ago, after Apple updated its own app Sherlock (a search tool on its desktop-operating system) to mimic a third-party application called Watson, which was created by Karelia Software to complement the Apple tool’s earlier version.[3] According to critics of self-preferencing generally and sherlocking in particular, biased intermediation and related conflicts of interest allow gatekeepers to exploit their preferential access to business users’ data to compete against them by replicating successful products and services. The implied assumption is that this strategy is relevant to competition policy, even where no potential intellectual-property rights (IPRs) are infringed and no slavish imitation sanctionable under unfair-competition laws is detected. Indeed, under such theories, sherlocking would already be prevented by the enforcement of these rules.

To tackle perceived misuse of gatekeepers’ market position, the European Union’s Digital Markets Act (DMA) introduced a ban on sherlocking.[4] Similar concerns have also motivated requests for intervention in the United States,[5] Australia,[6] and Japan.[7] In seeking to address at least two different theories of gatekeepers’ alleged conflicts of interest, these proposed bans on exploiting access to business users’ data are not necessarily limited to the risk of product imitation, but may include any business decision whatsoever that a platform may make while relying on that data.

In parallel with the regulatory initiatives, the conduct at-issue has also been investigated in some antitrust proceedings, which appear to seek the very same twofold goal. In particular, in November 2020, the European Commission sent a statement of objections to Amazon that argued the company had infringed antitrust rules through the systematic use of nonpublic business data from independent retailers who sell on the Amazon online marketplace in order to benefit Amazon’s own retail business, which directly competes with those retailers.[8] A similar investigation was opened by the UK Competition and Markets Authority (CMA) in July 2022.[9]

Further, as part of the investigation opened into Apple’s App Store rule requiring developers to use Apple’s in-app purchase mechanism to distribute paid apps and/or paid digital content, the European Commission also showed interest in evaluating whether Apple’s conduct might disintermediate competing developers from relevant customer data, while Apple obtained valuable data about those activities and its competitors’ offers.[10] The European Commission and UK CMA likewise launched an investigation into Facebook Marketplace, with accusations that Meta used data gathered from advertisers in order to compete with them in markets where the company is active, such as classified ads.[11]

There are two primary reasons these antitrust proceedings are relevant. First, many of the prohibitions envisaged in regulatory interventions (e.g., DMA) clearly took inspiration from the antitrust investigations, thus making it important to explore the insights that competition authorities may provide to support an outright ban. Second, given that regulatory intervention will be implemented alongside competition rules (especially in Europe) rather than displace them,[12] sherlocking can be assessed at both the EU and national level against dominant players that are not eligible for “gatekeeper” designation under the DMA. For those non-gatekeeper firms, the practice may still be investigated by antitrust authorities and assessed before courts, aside from the DMA’s per se prohibition. And, of course, investigations and assessments of sherlocking could also be made even in those jurisdictions where there isn’t an outright ban.

The former sis well-illustrated by the German legislature’s decision to empower its national competition authority with a new tool to tackle abusive practices that are similar and functionally equivalent to the DMA.[13] Indeed, as of January 2021, the Bundeskartellamt may identify positions of particular market relevance (undertakings of “paramount significance for competition across markets”) and assess their possible anticompetitive effects on competition in those areas of digital ecosystems in which individual companies may have a gatekeeper function. Both the initiative’s aims and its list of practices are similar to the DMA. They are distinguished primarily by the fact that the German list is exhaustive, and the practices at-issue are not prohibited per se, but are subject to a reversal of the burden of proof, allowing firms to provide objective justifications. For the sake of this analysis, within the German list, one provision prohibits designated undertakings from “demanding terms and conditions that permit … processing data relevant for competition received from other undertakings for purposes other than those necessary for the provision of its own services to these undertakings without giving these undertakings sufficient choice as to whether, how and for what purpose such data are processed.”[14]

Unfortunately, none of the above-mentioned EU antitrust proceedings have concluded with a final decision that addresses the merits of sherlocking. This precludes evaluating whether the practice would have survived before the courts. Regarding the Apple investigation, the European Commission dropped the case over App Store rules and issued a new statement of objections that no longer mentions sherlocking.[15] Further, the European Commission and the UK CMA accepted the commitments offered by Amazon to close those investigations.[16] The CMA likewise accepted the commitments offered by Meta.[17]

Those outcomes can be explained by the DMA’s recent entry into force. Indeed, because of the need to comply with the new regulation, players designated as gatekeepers likely have lost interest in challenging antitrust investigations that target the very same conduct prohibited by the DMA.[18] After all, given that the DMA does not allow any efficiency defense against the listed prohibitions, even a successful appeal against an antitrust decision would be a pyrrhic victory. From the opposite perspective, the same applies to the European Commission, which may decide to save time, costs, and risks by dropping an ongoing case against a company designated as a gatekeeper under the DMA, knowing that the conduct under investigation will be prohibited in any case.

Nonetheless, despite the lack of any final decision on sherlocking, these antitrust assessments remain relevant. As already mentioned, the DMA does not displace competition law and, in any case, dominant platforms not designated as gatekeepers under the DMA still may face antitrust investigations over sherlocking. This applies even more for jurisdictions, such as the United States, that are evaluating DMA-like legislative initiatives (e.g., the American Innovation and Choice Online Act, or “AICOA”).

Against this background, drawing on recent EU cases, this paper questions the alleged anticompetitive implications of sherlocking, as well as claims that the practice fails to comply with existing antitrust rules.

First, the paper illustrates that prohibitions on the use of nonpublic third-party business data would cover two different theories that should be analyzed separately. Whereas a broader case involves all the business decisions adopted by a dominant platform because of such preferential access (e.g., the launch of new products or services, the development or cessation of existing products or services, the calibration of pricing and management systems), a more specific case deals solely with the adoption of a copycat strategy. By conflating these theories in support of a blanket ban that condemns any use of nonpublic third-party business data, EU antitrust authorities are fundamentally motivated by the same policy goal pursued by the DMA—i.e., to impose a neutrality regime on large online platforms. The competitive implications differ significantly, however, as adopting copycat strategies may only affect intra-brand competition, while using said data to improve other business decisions could also affect inter-platform competition.

Second, the paper shows that, in both of these scenarios, the welfare effects of sherlocking are unclear. Notably, exploiting certain data to better understand the market could help a platform to develop new products and services, to improve existing products and services, or more generally to be more competitive with respect to both business users and other platforms. As such outcomes would benefit consumers in terms of price and quality, any competitive advantage achieved by the hybrid platform could be considered unlawful only if it is not achieved on the merits. In a similar vein, if sherlocking is used by a hybrid platform to deliver replicas of its business users’ products and services, that would likely provide short-term procompetitive effects benefitting consumers with more choice and lower prices. In this case, the only competitive harm that would justify an antitrust intervention resides in (uncertain) negative long-term effects on innovation.

As a result, in any case, an outright ban of sherlocking, such as is enshrined in the DMA, is economically unsound since it would clearly harm consumers.

The paper is structured as follows. Section II describes the recent antitrust investigations of sherlocking, illustrating the various scenarios that might include the use of third-party business data. Section III investigates whether sherlocking may be considered outside the scope of competition on the merits for bringing competitive advantages to platforms solely because of their hybrid business model. Section IV analyzes sherlocking as a copycat strategy by investigating the ambiguous welfare effects of copying in digital markets and providing an antitrust assessment of the practice at issue. Section V concludes.

II. Antitrust Proceedings on Sherlocking: Platform Neutrality and Copycat Competition

Policymakers’ interest in sherlocking is part of a larger debate over potentially unfair strategies that large online platforms may deploy because of their dual role as an unavoidable trading partner for business users and a rival in complementary markets.

In this scenario, as summarized in Table 1, the DMA outlaws sherlocking, establishing that to “prevent gatekeepers from unfairly benefitting from their dual role,”[19] they are restrained from using, in competition with business users, “any data that is not publicly available that is generated or provided by those business users in the context of their use of the relevant core platform services or of the services provided together with, or in support of, the relevant core platform services, including data generated or provided by the customers of those business users.”[20] Recital 46 further clarifies that the “obligation should apply to the gatekeeper as a whole, including but not limited to its business unit that competes with the business users of a core platform service.”

A similar provision was included in the American Innovation and Choice Online Act (AICOA), which was considered, but not ultimately adopted, in the 117^th U.S. Congress. AICOA, however, would limit the scope of the ban to the offer of products or services that would compete with those offered by business users.[21] Concerns about copycat strategies were also reported in the U.S. House of Representatives’ investigation of the state of competition in digital markets as supporting the request for structural-separation remedies and line-of-business restrictions to eliminate conflicts of interest where a dominant intermediary enters markets that place it in competition with dependent businesses.[22] Interestingly, however, in the recent complaint filed by the U.S. Federal Trade Commission (FTC) and 17 state attorneys general against Amazon that accuses the company of having deployed an interconnected strategy to block off every major avenue of competition (including price, product selection, quality, and innovation), there is no mention of sherlocking among the numerous unfair practices under investigation.[23]

Evaluating regulatory-reform proposals for digital markets, the Australian Competition and Consumer Commission (ACCC) also highlighted the risk of sherlocking, arguing that it could have an adverse effect on competition, notably on rivals’ ability to compete, when digital platforms exercise their strong market position to utilize nonpublic data to free ride on the innovation efforts of their rivals.[24] Therefore, the ACCC suggested adopting service-specific codes to address self-preferencing by, for instance, imposing data-separation requirements to restrain dominant app-store providers from using commercially sensitive data collected from the app-review process to develop their own apps.[25]

Finally, on a comparative note, it is also useful to mention the proposals advanced by the Japanese Fair Trade Commission (JFTC) in its recent market-study report on mobile ecosystems.[26] In order to ensure equal footing among competitors, the JFTC specified that its suggestion to prevent Google and Apple from using nonpublic data generated by other developers’ apps aims at pursuing two purposes. Such a ban would, indeed, concern not only use of the data for the purpose of developing competing apps, products, and services, but also its use for developing their own apps, products, and services.

TABLE 1: Legislative Initiatives and Proposals to Ban Sherlocking

As previously anticipated, sherlocking recently emerged as an antitrust offense in three investigations launched by the European Commission and the UK CMA.

In the first case, Amazon’s alleged reliance on marketplace sellers’ nonpublic business data has been claimed to distort fair competition on its platform and prevent effective competition. In its preliminary findings, the Commission argued that Amazon takes advantage of its hybrid business model, leveraging its access to nonpublic third-party sellers’ data (e.g., the number of ordered and shipped units of products; sellers’ revenues on the marketplace; the number of visits to sellers’ offers; data relating to shipping, to sellers’ past performance, and to other consumer claims on products, including the activated guarantees) to adjust its retail offers and strategic business decisions to the detriment of third-party sellers, which are direct competitors on the marketplace.[27] In particular, the Commission was concerned that Amazon uses such data for its decision to start and end sales of a product, for its pricing system, for its inventory-planning and management system, and to identify third-party sellers that Amazon’s vendor-recruitment teams should approach to invite them to become direct suppliers to Amazon Retail. To address the data-use concern, Amazon committed not to use nonpublic data relating to, or derived from, independent sellers’ activities on its marketplace for its retail business and not to use such data for the purposes of selling branded goods, as well as its private-label products.[28]

A parallel investigation ended with similar commitments in the UK.[29] According to the UK CMA, Amazon’s access to and use of nonpublic seller data could result in a competitive advantage for Amazon Retail arising from its operation of the marketplace, rather than from competition on the merits, and may lead to relevant adverse effects on competition. Notably, it was alleged this could result in a reduction in the scale and competitiveness of third-party sellers on the Amazon Marketplace; a reduction in the number and range of product offers from third-party sellers on the Amazon Marketplace; and/or less choice for consumers, due to them being offered lower quality goods and/or paying higher prices than would otherwise be the case.

It is also worth mentioning that, by determining that Amazon is an undertaking of paramount significance for competition across markets, the Bundeskartellamt emphasized the competitive advantage deriving from Amazon’s access to nonpublic data, such as Glance Views, sales figures, sale quantities, cost components of products, and reorder status.[30] Among other things, with particular regard to Amazon’s hybrid role, the Bundeskartellamt noted that the preferential access to competitively sensitive data “opens up the possibility for Amazon to optimize its own-brand assortment.”[31]

A second investigation involved Apple and its App Store rule.[32] According to the European Commission, the mandatory use of Apple’s own proprietary in-app purchase system (IAP) would, among other things, grant Apple full control over the relationship its competitors have with customers, thus disintermediating those competitors from customer data and allowing Apple to obtain valuable data about the activities and offers of its competitors.

Finally, Meta faced antitrust proceedings in both the EU and the UK.[33] The focus was on Facebook Marketplace—i.e., an online classified-ads service that allows users to advertise goods for sale. According to the European Commission and the CMA, Meta unilaterally imposes unfair trading conditions on competing online-classified ads services that advertise on Facebook or Instagram. These terms and conditions, which authorize Meta to use ads-related data derived from competitors for the benefit of Facebook Marketplace, are considered unjustified, as they impose an unnecessary burden on competitors and only benefit Facebook Marketplace. The suspicion is that Meta has used advertising data from Facebook Marketplace competitors for the strategic planning, product development, and launch of Facebook Marketplace, as well as for Marketplace’s operation and improvement.

Overall, these investigations share many features. The concerns about third-party business-data use, as well as about other forms of self-preferencing, revolve around the competitive advantages that accrue to a dominant platform because of its dual role. Such advantages are considered unfair, as they are not the result of the merits of a player, but derived purely and simply from its role as an important gateway to reach end users. Moreover, this access to valuable business data is not reciprocal. The feared risk is the marginalization of business users competing with gatekeepers on the gatekeepers’ platforms and, hence, the alleged harm to competition is the foreclosure of rivals in complementary markets (horizontal foreclosure).

The focus of these investigations was well-illustrated by the European Commission’s decision on Amazon’s practice.[34] The Commission’s concern was about the “data delta” that Amazon may exploit, namely the additional data related to third-party sellers’ listings and transactions that are not available to, and cannot be replicated by, the third-party sellers themselves, but are available to and used by Amazon Retail for its own retail operations.[35] Contrary to Amazon Retail—which, according to Commission’s allegations, would have full access to and would use such individual, real-time data of all its third-party sellers to calibrate its own retail decisions—sellers would have access only to their own individual listings and sales data. As a result, the Commission came to the (preliminary) conclusion that real-time access to and use of such volume, variety, and granularity of non-publicly available data from its retail competitors generates a significant competitive advantage for Amazon Retail in each of the different decisional processes that drive its retail operations.[36]

On a closer look, however, while antitrust authorities seem to target the use of nonpublic third-party business data as a single theory of harm, their allegations cover two different scenarios along the lines of what has already been examined with reference to the international legislative initiatives and proposals. Indeed, the Facebook Marketplace case does not involve an allegation of copying, as Meta is accused of gathering data from its business users to launch and improve its ads service, instead of reselling goods and services.

FIGURE 1: Sherlocking in Digital Markets

As illustrated above in Figure 1, while the claim in the latter scenario is that the preferential data use would help dominant players calibrate business decisions in general, the former scenario instead involves the use of such data for a pure copycat strategy of an entire product or service, or some of its specific features.

In both scenarios the aim of the investigations is to ensure platform neutrality. Accordingly, as shown by the accepted commitments, the envisaged solution for antitrust authorities is to impose  data-separation requirements to restrain dominant platforms from using third-party commercially sensitive data. Putting aside that these investigations concluded with commitments from the firms, however, their chances of success before a court differ significantly depending on whether they challenge a product-imitation strategy, or any business decision adopted because of the “data delta.”

A. Sherlocking and Unconventional Theories of Harm for Digital Markets

Before analyzing how existing competition-law rules could be applied to the various scenarios involving the use of third-party business data, it is worth providing a brief overview of the framework in which the assessment of sherlocking is conducted. As competition in the digital economy is increasingly a competition among ecosystems,[37] a lively debate has emerged on the capacity of traditional antitrust analysis to adequately capture the peculiar features of digital markets. Indeed, the combination of strong economies of scale and scope; indirect network effects; data advantages and synergies across markets; and portfolio effects all facilitate ecosystem development all contribute to making digital markets highly concentrated, prone to tipping, and not easily contestable.[38] As a consequence, it’s been suggested that addressing these distinctive features of digital markets requires an overhaul of the antitrust regime.

Such discussions require the antitrust toolkit and theories of harm to illustrate whether and how a particular practice, agreement, or merger is anticompetitive. Notably, at issue is whether traditional antitrust theories of harm are fit for purpose or whether novel theories of harm should be developed in response to the emerging digital ecosystems. The latter requires looking at the competitive impact of expanding, protecting, or strengthening an ecosystem’s position, and particularly whether such expansion serves to exploit a network of capabilities and to control access to key inputs and components.[39]

A significant portion of recent discussions around developing novel theories of harm to better address the characteristics of digital-business models and markets has been devoted to the topic of merger control—in part a result of the impressive number of acquisitions observed in recent years.[40] In particular, the focus has been on analyzing conglomerate mergers that involve acquiring a complementary or unrelated asset, which have traditionally been assumed to raise less-significant competition concerns.

In this regard, an ecosystem-based theory seems to have guided the Bundeskartellamt in its assessment of Meta’s acquisition of Kustomer[41] and by the CMA in Microsoft/Activision.[42] A more recent example is the European Commission’s decision to prohibit the proposed Booking/eTraveli merger, where the Commission explicitly noted that the transaction would have allowed Booking to expand its travel-services ecosystem.[43] The Commission’s concerns were related primarily to the so-called “envelopment” strategy, in which a prominent platform within a specific market broadens its range of services into other markets where there is a significant overlap of customer groups already served by the platform.[44]

Against this background, putative self-preferencing harms represent one of the European Commission’s primary (albeit contentious)[45] attempts to develop new theories of harm built on conglomerate platforms’ ability to bundle services or use data from one market segment to inform product development in another.[46] Originally formulated in the Google Shopping decision,[47] the theory of harm of (leveraging through) self-preferencing has subsequently inspired the DMA, which targets different forms of preferential treatment, including sherlocking.

In particular, it is asserting that platform may use self-preferencing to adopt a leveraging strategy with a twofold anticompetitive effect—that is, excluding or impeding rivals from competing with the platform (defensive leveraging) and extending the platform’s market power into associated markets (offensive leveraging). These goals can be pursued because of the unique role that some large digital platforms play. That is, they not only enjoy strategic market status by controlling ecosystems of integrated complementary products and services, which are crucial gateways for business users to reach end users, but they also perform a dual role as both a critical intermediary and a player active in complementors’ markets. Therefore, conflicts of interests may provide incentives for large vertically integrated platforms to favor their own products and services over those of their competitors.[48]

The Google Shopping theory of harm, while not yet validated by the Court of Justice of the European Union (CJEU),[49] has also found its way into merger analysis, as demonstrated by the European Commission’s recent assessment of iRobot/Amazon.[50] In its statement of objections, the Commission argued that the proposed acquisition of iRobot may give Amazon the ability and incentive to foreclose iRobot’s rivals by engaging in several foreclosing strategies to prevent them from selling robot vacuum cleaners (RVCs) on Amazon’s online marketplace and/or at degrading such rivals’ access to that marketplace. In particular, the Commission found that Amazon could deploy such self-preferencing strategies as delisting rival RVCs; reducing rival RVCs’ visibility in both organic and paid results displayed in Amazon’s marketplace; limiting access to certain widgets or commercially attractive labels; and/or raising the costs of iRobot’s rivals to advertise and sell their RVCs on Amazon’s marketplace.[51]

Sherlocking belongs to this framework of analysis and can be considered a form of self-preferencing, specifically because of the lack of reciprocity in accessing sensitive data.[52] Indeed, while gatekeeper platforms have access to relevant nonpublic third-party business data as a result of their role as unavoidable trading partners, they leverage this information exclusively, without sharing it with third-party sellers, thus further exacerbating an already uneven playing field.[53]

III. Sherlocking for Competitive Advantage: Hybrid Business Model, Neutrality Regimes, and Competition on the Merits

Insofar as prohibitions of sherlocking center on the competitive advantages that platforms enjoy because of their dual role—thereby allowing some players to better calibrate their business decisions due to their preferential access to business users’ data—it should be noted that competition law does not impose a general duty to ensure a level playing field.[54] Further, a competitive advantage does not, in itself, amount to anticompetitive foreclosure under antitrust rules. Rather, foreclosure must not only be proved (in terms of actual or potential effects) but also assessed against potential benefits for consumers in terms of price, quality, and choice of new goods and services.[55]

Indeed, not every exclusionary effect is necessarily detrimental to competition.[56] Competition on the merits may, by definition, lead to the departure from the market or the marginalization of competitors that are less efficient and therefore less attractive to consumers from the point of view of, among other things, price, choice, quality or innovation.[57] Automatically classifying any conduct with exclusionary effects were as anticompetitive could well become a means to protect less-capable, less-efficient undertakings and would in no way protect more meritorious undertakings—thereby potentially hindering a market’s competitiveness.[58]

As recently clarified by the CJEU regarding the meaning of “competition on the merits,” any practice that, in its implementation, holds no economic interest for a dominant undertaking except that of eliminating competitors must be regarded as outside the scope of competition on the merits.[59] Referring to the cases of margin squeezes and essential facilities, the CJEU added that the same applies to practices that a hypothetical equally efficient competitor is unable to adopt because that practice relies on using resources or means inherent to the holding of such a dominant position.[60]

Therefore, while antitrust cases on sherlocking set out to ensure a level playing field and platform neutrality, and therefore center on the competitive advantages that a platform enjoys because of its dual role, mere implementing a hybrid business model does not automatically put such practices outside the scope of competition on the merits. The only exception, according to the interpretation provided in Bronner, is the presence of an essential facility—i.e., an input whose access should be considered indispensable, as there are no technical, legal, or economic obstacles capable of making it impossible, or even unreasonably difficult, to duplicate it.[61]

As a result, unless it is proved that the hybrid platform is an essential facility, sherlocking and other forms of self-preferencing cannot be considered prima facie outside the scope of competition on the merits, or otherwise unlawful. Rather, any assessment of sherlocking demands the demonstration of anticompetitive effects, which in turn requires finding an impact on efficient firms’ ability and incentive to compete. In the scenario at-issue, for instance, the access to certain data may allow a platform to deliver new products or services; to improve existing products or services; or more generally to compete more efficiently not only with respect to the platform’s business users, but also against other platforms. Such an increase in both intra-platform and inter-platform competition would benefit consumers in terms of lower prices, better quality, and a wider choice of new or improved goods and services—i.e., competition on the merits.[62]

In Facebook Marketplace, the European Commission and UK CMA challenged the terms and conditions governing the provision of display-advertising and business-tool services to which Meta required its business customers to sign up.[63] In their view, Meta abused its dominant position by imposing unfair trading conditions on its advertising customers, which authorized Meta to use ads-related data derived from the latter in a way that could afford Meta a competitive advantage on Facebook Marketplace that would not have arisen from competition on the merits. Notably, antitrust authorities argued that Meta’s terms and conditions were unjustified, disproportionate, and unnecessary to provide online display-advertising services on Meta’s platforms.

Therefore, rather than directly questioning the platform’s dual role or hybrid business model, the European Commission and UK CMA decided to rely on traditional case law which considers unfair those clauses that are unjustifiably unrelated to the purpose of the contract, unnecessarily limit the parties’ freedom, are disproportionate, or are unilaterally imposed or seriously opaque.[64] This demonstrates that, outside the harm theory of the unfairness of terms and conditions, a hybrid platform’s use of nonpublic third-party business data to improve its own business decisions is generally consistent with antitrust provisions. Hence, an outright ban would be unjustified.

IV. Sherlocking to Mimic Business Users’ Products or Services

The second, and more intriguing, sherlocking scenario is illustrated by the Amazon Marketplace investigations and regards the original meaning of sherlocking—i.e., where a data advantage is used by a hybrid platform to mimic its business users’ products or services.

Where sherlocking charges assert that the practice allows some platforms to use business users’ data to compete against them by replicating their products or services, it should not be overlooked that the welfare effects of such a copying strategy are ambiguous. While the practice could benefit consumers in the short term by lowering prices and increasing choice, it may discourage innovation over the longer term if third parties anticipate being copied whenever they deliver successful products or services. Therefore, the success of an antitrust investigation essentially relies on demonstrating a harm to innovation that would induce business users to leave the market or stop developing their products and services. In other words, antitrust authorities should be able to demonstrate that, by allowing dominant platforms to free ride on their business guests’ innovation efforts, sherlocking would negatively affect rivals’ ability to compete.

A. The Welfare Effects of Copying

The tradeoff between the short- and long-term welfare effects of copying has traditionally been analyzed in the context of the benefits and costs generated by intellectual-property protection.[65] In particular, the economic literature investigating the optimal life of patents[66] and copyrights[67] focuses on the efficient balance between dynamic benefits associated with innovation and the static costs of monopoly power granted by IPRs.

More recently, product imitation has instead been investigated in the different scenario of digital markets, where dominant platforms adopting a hybrid business model may use third-party sellers’ market data to design and promote their own products over their rivals’ offerings. Indeed, some studies report that large online platforms may attempt to protect their market position by creating “kill zones” around themselves—i.e., by acquiring, copying, or eliminating their rivals.[68] In such a novel setting, the welfare effects of copying are assessed regardless of the presence and the potential enforcement of IPRs, but within a strategy aimed at excluding rivals by exploiting the dual role of both umpire and player to get preferential access to sensitive data and free ride on their innovative efforts.[69]

Even in this context, however, a challenging tradeoff should be considered. Indeed, while in the short term, consumers may benefit from the platform’s imitation strategy in terms of lower prices and higher quality, they may be harmed in the longer term if third parties are discouraged from delivering new products and services. As a result, while there is empirical evidence on hybrid platforms successfully entering into third parties’ adjacent market segments, [70] the extant academic literature finds the welfare implications of such moves to be ambiguous.

A first strand of literature attempts to estimate the welfare impact of the hybrid business model. Notably, Andre Hagiu, Tat-How Teh, and Julian Wright elaborated a model to address the potential implications of an outright ban on platforms’ dual mode, finding that such a structural remedy may harm consumer surplus and welfare even where the platform would otherwise engage in product imitation and self-preferencing.[71] According to the authors, banning the dual mode does not restore the third-party seller’s innovation incentives or the effective price competition between products, which are the putative harms caused by imitation and self-preferencing. Therefore, the authors’ evaluation was that interventions specifically targeting product imitation and self-preferencing were preferable.

Germa?n Gutie?rrez suggested that banning the dual model would generate hardly any benefits for consumers, showing that, in the Amazon case, interventions that eliminate either the Prime program or product variety are likely to decrease welfare.[72]

Further, analyzing Amazon’s business model, Federico Etro found that the platform and consumers’ incentives are correctly aligned, and that Amazon’s business model of hosting sellers and charging commissions prevents the company from gaining through systematic self?preferencing for its private-label and first-party products.[73] In the same vein, on looking at its business model and monetization strategy, Patrick Andreoli-Versbach and Joshua Gans argued that Amazon does not have an obvious incentive to self-preference.[74] Indeed, Amazon’s profitability data show that, on average, the company’s operating margin is higher on third-party sales than on first-party retail sales.

Looking at how modeling details may yield different results with regard to the benefits and harms of the hybrid business model, Simon Anderson and O?zlem Bedre-Defoile maintain that the platform’s choice to sell its own products benefits consumers by lowering prices when a monopoly platform hosts competitive fringe sellers, regardless of the platform’s position as a gatekeeper, whether sellers have an alternate channel to reach consumers, or whether alternate channels are perfect or imperfect substitutes for the platform channel.[75] On the other hand, the authors argued that platform product entry might harm consumers when a big seller with market power sells on its own channel and also on the platform. Indeed, in that case, the platform setting a seller fee before the big seller prices its differentiated products introduces double markups on the big seller’s platform-channel price and leaves some revenue to the big seller.

Studying whether Amazon engages in self-preferencing on its marketplace by favoring its own brands in search results, Chiara Farronato, Andrey Fradkin, and Alexander MacKay demonstrate empirically that Amazon brands remain about 30% cheaper and have 68% more reviews than other similar products.[76] The authors acknowledge, however, that their findings do not imply that consumers are hurt by Amazon brands’ position in search results.

Another strand of literature specifically tackles the welfare effects of sherlocking. In particular, Erik Madsen and Nikhil Vellodi developed a theoretical framework to demonstrate that a ban on insider imitation can either stifle or stimulate innovation, depending on the nature of innovation.[77] Specifically, the ban could stimulate innovation for experimental product categories, while reducing innovation in incremental product markets, since the former feature products with a large chance of superstar demand and the latter generate mostly products with middling demand.

Federico Etro maintains that the tradeoffs at-issue are too complex to be solved with simple interventions, such as bans on dual mode, self-preferencing, or copycatting.[78] Indeed, it is difficult to conclude that Amazon entry is biased to expropriate third-party sellers or that bans on dual mode, self-preferencing, or copycatting would benefit consumers, because they either degrade services and product variety or induce higher prices or commissions.

Similar results are provided by Jay Pil Choi, Kyungmin Kim, and Arijit Mukherjee, who developed a tractable model of a platform-run marketplace where the platform charges a referral fee to the sellers for access to the marketplace, and may also subsequently launch its own private-label product by copying a seller.[79] The authors found that a policy to either ban hybrid mode or only prohibit information use for the launch of private-label products may produce negative welfare implications.

Further, Radostina Shopova argues that, when introducing a private label, the marketplace operator does not have incentive to distort competition and foreclose the outside seller, but does have an incentive to lower fees charged to the outside seller and to vertically differentiate its own product in order to protect the seller’s channel.[80] Even when the intermediary is able to perfectly mimic the quality of the outside seller and monopolize its product space, the intermediary prefers to differentiate its offer and chooses a lower quality for the private-label product. Accordingly, as the purpose of private labels is to offer a lower-quality version of products aimed at consumers with a lower willingness to pay, a marketplace operator does not have an incentive to distort competition in favor of its own product and foreclose the seller of the original higher-quality product.

In addition, according to Jean-Pierre Dubé, curbing development of private-label programs would harm consumers and Amazon’s practices amount to textbook retailing, as they follow an off-the-shelf approach to managing private-label products that is standard for many retail chains in the West.[81] As a result, singling out Amazon’s practices would set a double standard.

Interestingly, such findings about predictors and effects of Amazon’s entry in competition with third-party merchants on its own marketplace are confirmed by the only empirical study developed so far. In particular, analyzing the Home & Kitchen department of Germany’s version of Amazon Marketplace between 2016 and 2021, Gregory S. Crawford, Matteo Courthoud, Regina Seibel, and Simon Zuzek’s results suggest that Amazon’s entry strategy was more consistent with making Marketplace more attractive to consumers than expropriating third-party merchants.[82] Notably, the study showed that, comparing Amazon’s entry decisions with those of the largest third-party merchants, Amazon tends to enter low-growth and low-quality products, which is consistent with a strategy that seeks to make Marketplace more attractive by expanding variety, lessening third-party market power, and/or enhancing product availability. The authors therefore found that Amazon’s entry on Amazon Marketplace demonstrated no systematic adverse effects and caused a mild market expansion.

Massimo Motta and Sandro Shelegia explored interactions between copying and acquisitions, finding that the former (or the threat of copying) can modify the outcome of an acquisition negotiation.[83] According to their model, there could be both static and dynamic incentives for an incumbent to introduce a copycat version of a complementary product. The static rationale consists of lowering the price of the complementary product in order to capture more rents from it, while the dynamic incentive consists of harming a potential rival’s prospects of developing a substitute. The latter may, in turn, affect the direction the entrant takes toward innovation. Anticipating the incumbent’s copying strategy, the entrant may shift resources from improvements to compete with the incumbent’s primary product to developing complementary products.

Jingcun Cao, Avery Haviv, and Nan Li analyzed the opposite scenario—i.e., copycats that seek to mimic the design and user experience of incumbents’ successful products.[84] The authors find empirically that, on average, copycat apps do not have a significant effect on the demand for incumbent apps and that, as with traditional counterfeit products, they may generate a positive demand spillover toward authentic apps.

Massimo Motta also investigated the potential foreclosure effects of platforms adopting a copycat strategy committed to non-discriminatory terms of access for third parties (e.g., Apple App Store, Google Play, and Amazon Marketplace).[85] Notably, according to Motta, when a third-party seller is particularly successful and the platform is unable to raise fees and commissions paid by that seller, the platform may prefer to copy its product or service to extract more profits from users, rather than rely solely on third-party sales. The author acknowledged, however, that even though this practice may create an incentive for self-preferencing, it does not necessarily have anticompetitive effects. Indeed, the welfare effects of the copying strategy are a priori ambiguous.[86] While, on the one hand, the platform’s copying of a third-party product benefits consumers by increasing variety and competition among products, on the other hand, copying might be wasteful for society, in that it entails a fixed cost and may discourage innovation if rivals anticipate that they will be systematically copied whenever they have a successful product.[87] Therefore, introducing a copycat version of a product offered by a firm in an adjacent market might be procompetitive.

B. Antitrust Assessment: Competition, Innovation, and Double Standards

The economic literature has demonstrated that the rationale and welfare effects of sherlocking by hybrid platforms are definitively ambiguous. Against concerns about rivals’ foreclosure, some studies provide a different narrative, illustrating that such a strategy is more consistent with making the platform more attractive to consumers (by differentiating the quality and pricing of the offer) than expropriating business users.[88] Furthermore, copies, imitations, and replicas undoubtedly benefit consumers with more choice and lower prices.

Therefore, the only way to consider sherlocking anticompetitive is by demonstrating long-term deterrent effects on innovation (i.e., reducing rivals’ incentives to invest in new products and services) outweigh consumers’ short-term advantages.[89] Moreover, deterrent effects must not be merely hypothetical, as a finding of abuse cannot be based on a mere possibility of harm.[90] In any case, such complex tradeoffs are at odds with a blanket ban.[91]

Moreover, assessments of the potential impact of sherlocking on innovation cannot disregard the role of IPRs—which are, by definition, the main primary to promote innovation. From this perspective, intellectual-property protection is best characterized as another form of tradeoff. Indeed, the economic rationale of IPRs (in particular, of patents and copyrights) involves, among other things, a tradeoff between access and incentives—i.e., between short-term competitive restrictions and long-term innovative benefits.[92]

According to the traditional incentive-based theory of intellectual property, free riding would represent a dangerous threat that justifies the exclusive rights granted by intellectual-property protection. As a consequence, so long as copycat expropriation does not infringe IPRs, it should be presumed legitimate and procompetitive. Indeed, such free riding is more of an intellectual-property issue than a competitive concern.

In addition, to strike a fair balance between restricting competition and providing incentives to innovation, the exclusive rights granted by IPRs are not unlimited in terms of duration, nor in terms of lawful (although not authorized) uses of the protected subject matter. Under the doctrine of fair use, for instance, reverse engineering represents a legitimate way to obtain information about a firm’s product, even if the intended result is to produce a directly competing product that may steer customers away from the initial product and the patented invention.

Outside of reverse engineering, copying is legitimately exercised once IPRs expire, when copycat competitors can reproduce previously protected elements. As a result of the competitive pressure exerted by new rivals, holders of expired IPRs may react by seeking solutions designed to block or at least limit the circulation of rival products. They could, for example, request other IPRs to cover aspects or functionalities different from those previously protected. They could also bring (sometimes specious) legal action for infringement of the new IPR or for unfair competition by slavish imitation. For these reasons, there have been occasions where copycat competitors have received protection from antitrust authorities against sham litigation brought by IPR holders concerned about losing margins due to pricing pressure from copycats.[93]

Finally, within the longstanding debate on the intersection of intellectual-property protection and competition, EU antitrust authorities have traditionally been unsympathetic toward restrictions imposed by IPRs. The success of the essential-facility doctrine (EFD) is the most telling example of this attitude, as its application in the EU has been extended to IPRs. As a matter of fact, the EFD represents the main antitrust tool for overseeing intellectual property in the EU.[94]

After Microsoft, EU courts have substantially dismantled one of the “exceptional circumstances” previously elaborated in Magill and specifically introduced for cases involving IPRs, with the aim of safeguarding a balance between restrictions to access and incentives to innovate. Whereas the CJEU established in Magill that refusal to grant an IP license should be considered anticompetitive if it prevents the emergence of a new product for which there is potential consumer demand, in Microsoft, the General Court considered such a requirement met even when access to an IPR is necessary for rivals to merely develop improved products with added value.

Given this background, recent competition-policy concerns about sherlocking are surprising. To briefly recap, the practice at-issue increases competition in the short term, but may affect incentives to innovate in the long-term. With regard to the latter, however, the practice neither involves products protected by IPRs nor constitutes a slavish imitation that may be caught under unfair-competition laws.

The case of Amazon, which has received considerable media coverage, is illustrative of the relevance of IP protection. Amazon has been accused of cloning batteries, power strips, wool runner shoes, everyday sling bags, camera tripods, and furniture.[95] One may wonder what kind of innovation should be safeguarded in these cases against potential copies. Admittedly, such examples appear consistent with the findings of the already-illustrated empirical study conducted by Crawford et al. indicating that Amazon tends to enter low-quality products in order to expand variety on the Marketplace and to make it more attractive to consumers.

Nonetheless, if an IPR is involved, right holders are provided with proper means to protect their products against infringement. Indeed, one of the alleged targeted companies (Williams-Sonoma) did file a complaint for design and trademark infringement, claiming that Amazon had copied a chair (Orb Dining Chair) sold by its West Elm brand. According to Williams-Sonoma, the Upholstered Orb Office Chair—which Amazon began selling under its Rivet brand in 2018—was so similar that the ordinary observer would be confused by the imitation.[96] If, instead, the copycat strategy does not infringe any IPR, the potential impact on innovation might not be considered particularly worrisome—at least at first glance.

Further, neither the degree to which third-party business data is unavailable nor the degree to which they are relevant in facilitating copying are clear cut. For instance, in the case of Amazon, public product reviews supply a great deal of information[97] and, regardless of the fact that a third party is selling a product on the Marketplace, anyone can obtain an item for the purposes of reverse engineering.[98]

In addition, antitrust authorities are used to intervening against opportunistic behavior by IPR holders. European competition authorities, in particular, have never before seemed particularly responsive to the motives of inventors and creators versus the need to encourage maximum market openness.

It should also be noted that cloning is a common strategy in traditional markets (e.g., food products)[99] and has been the subject of longstanding controversies between high-end fashion brands and fast-fashion brands (e.g., Zara, H&M).[100] Furthermore, brick-and-mortar retailers also introduce private labels and use other brands’ sales records in deciding what to produce.[101]

So, what makes sherlocking so different and dangerous when deployed in digital markets as to push competition authorities to contradict themselves?[102]

The double standard against sherlocking reflects the same concern and pursues the same goal of the various other attempts to forbid any form of self-preferencing in digital markets. Namely, antitrust investigations of sherlocking are fundamentally driven by the bias against hybrid and vertically integrated players. The investigations rely on the assumption that conflicts of interest have anticompetitive implications and that, therefore, platform neutrality should be promoted to ensure the neutrality of the competitive process.[103] Accordingly, hostility toward sherlocking may involve both of the illustrated scenarios—i.e., the use of nonpublic third-party business data either in adopting any business decision, or just copycat strategies, in particular.

As a result, however, competition authorities end up challenging a specific business model, rather than the specific practice at-issue, which brings undisputed competitive benefits in terms of lower prices and wider consumer choice, and which should therefore be balanced against potential exclusionary risks. As the CJEU has pointed out, the concept of competition on the merits:

…covers, in principle, a competitive situation in which consumers benefit from lower prices, better quality and a wider choice of new or improved goods and services. Thus, … conduct which has the effect of broadening consumer choice by putting new goods on the market or by increasing the quantity or quality of the goods already on offer must, inter alia, be considered to come within the scope of competition on the merits.[104]

Further, in light of the “as-efficient competitor” principle, competition on the merits may lead to “the departure from the market, or the marginalization of, competitors that are less efficient and so less attractive to consumers from the point of view of, among other things, price, choice, quality or innovation.”[105]

It has been correctly noted that the “as-efficient competitor” principle is a reminder of what competition law is about and how it differs from regulation.[106] Competition law aims to protect a process, rather than engineering market structures to fulfill a particular vision of how an industry is to operate.[107] In other words, competition law does not target firms on the basis of size or status and does not infer harm from (market or bargaining) power or business model. Therefore, neither the dual role played by some large online platforms nor their preferential access to sensitive business data or their vertical integration, by themselves, create a competition problem. Competitive advantages deriving from size, status, power, or business model cannot be considered per se outside the scope of competition on the merits.

Some policymakers have sought to resolve these tensions in how competition law regards sherlocking by introducing or envisaging an outright ban. These initiatives and proposals have clearly been inspired by antitrust investigations, but they did so for the wrong reasons. Instead of taking stock of the challenging tradeoffs between short-term benefits and long-term risks that an antitrust assessment of sherlocking requires, they blamed competition law for not providing effective tools to achieve the policy goal of platform neutrality.[108] Therefore, the regulatory solution is merely functional to bypass the traditional burden of proof of antitrust analysis and achieve what competition-law enforcement cannot provide.

V. Conclusion

The bias against self-preferencing strikes again. Concerns about hybrid platforms’ potential conflicts of interest have led policymakers to seek prohibitions to curb different forms of self-preferencing, making the latter the symbol of the competition-policy zeitgeist in digital markets. Sherlocking shares this fate. Indeed, the DMA outlaws any use of business users’ nonpublic data and similar proposals have been advanced in the United States, Australia, and Japan. Further, like other forms of self-preferencing, such regulatory initiatives against sherlocking have been inspired by previous antitrust proceedings.

Drawing on these antitrust investigations, the present research shows the extent to which an outright ban on sherlocking is unjustified. Notably, the practice at-issue includes two different scenarios: the broad case in which a gatekeeper exploits its preferential access to business users’ data to better calibrate all of its business decisions and the narrow case in which such data is used to adopt a copycat strategy. In either scenario, the welfare effects and competitive implications of sherlocking are unclear.

Indeed, the use of certain data by a hybrid platform to improve business decisions generally should be classified as competition on the merits, and may yield an increase in both intra-platform (with respect to business users) and inter-platform (with respect to other platforms) competition. This would benefit consumers in terms of lower prices, better quality, and a wider choice of new or improved goods and services. In a similar vein, if sherlocking is used to deliver replicas of business users’ products or services, the anti-competitiveness of such a strategy may only result from a cumbersome tradeoff between short-term benefits (i.e., lower prices and wider choice) and negative long-term effects on innovation.

An implicit confirmation of the difficulties encountered in demonstrating the anti-competitiveness of sherlocking comes from the recent complaint issued by the FTC against Amazon.[109] Current FTC Chairwoman Lina Khan devoted a significant portion of her previous academic career to questioning Amazon’s practices (including the decision to introduce its own private labels inspired by third-party products)[110] and to supporting the adoption of structural-separation remedies to tackle platforms’ conflicts of interest that induce them to exploit their “systemic informational advantage (gleaned from competitors)” to thwart rivals and strengthen their own position by introducing replica products.[111] Despite these premises and although the FTC’s complaint targets numerous practices belonging to what has been described as an interconnected strategy to block off every major avenue of competition, however, sherlocking is surprisingly off the radar.

Regulatory initiatives to ban sherlocking in order to ensure platform neutrality with respect to business users and a level playing field among rivals would sacrifice undisputed procompetitive benefits on the altar of policy goals that competition rules are not meant to pursue. Sherlocking therefore appears to be a perfect case study of the side effects of unwarranted interventions in digital markets.

The Federal Communications Commission has voted on yet another round of net neutrality rules. Its vote Thursday reprises the 2015 rules, which resuscitated the 1934 Communications Act for modern, high-speed broadband networks. The agency decided, by a partisan split of 3-2, to end the “abdication of authority over broadband in 2017” and the ensuing years of “no federal oversight.”

With yet another net-neutrality order set to take effect (the link is to the draft version circulated before today’s Federal Communications Commission vote; the final version is expected to be published in a few weeks) and to impose common-carriage requirements on broadband internet-access service (BIAS) providers, it is worth considering how the question of whether online platforms (whether they be social media or internet service providers) have the right to editorial discretion keeps shifting.

Read the full piece here.

ICLE Senior Scholar Eric Fruits was quoted by Law360 in a story about the Federal Communications Commission’s vote to reimpose Title II regulation on broadband internet-access service providers. You can read the full piece here.

“I’m skeptical that Congress would actually act to do any sort of CRA reversal,” said Eric Fruits, a senior scholar at the International Center for Law and Economics, and a critic of the order. “And so that means you’re going to have the lawsuits. And the other big story of the year would be if no one filed a lawsuit. I bet you there’s someone, somewhere, who already has a lawsuit written.”

PORTLAND, Ore. (April 23, 2024) – The International Center for Law & Economics (ICLE) offers the following statement on today’s vote by the Federal Communications Commission (FTC) to adopt a rule classifying internet service providers (ISPs) under Title II of the Communications Act.

The following quote can be attributed to ICLE Senior Scholar Eric Fruits:

Title II is much more than net neutrality. It is the same type of expansive and heavy-handed regulation that governs public utilities. The FCC’s rule is a sharp reversal from decades of light-touch regulation that has fostered America’s leadership in broadband innovation and investment. The industry would face the yoke of onerous federal regulation and meddling that would stifle and slow future investment and experimentation.

For more on the topic, see ICLE’s issue spotlight laying out the history of Title II and net neutrality, as well as our comments to the FCC on their notice of proposed rulemaking (NPRM). To schedule an interview with Eric about the topic, contact ICLE Media and Communications Manager Elizabeth Lincicome at (919) 744-8087 or [email protected].

The Issue

Net neutrality is the idea that internet service providers (ISPs) should treat all data transmitted over the internet the same, and should not discriminate among consumers, entities that provide content, or applications that use the internet. Whether net neutrality should be mandated by rules and regulations—such as the Federal Communications Commission’s (FCC) latest net-neutrality regulations—has been a highly controversial topic since the early 2000s. In the years since 2010, the FCC has imposed net-neutrality rules (1,2), only to see them struck down by courts or repealed, as the commission’s partisan makeup changed.

Executive Summary

We are thankful for the opportunity to submit our comments to the Preliminary Report (hereinafter, the Report)[1] published by the Investigative Authority (IA) of the Federal Economic Competition Commission (COFECE, after its Spanish acronym) following its investigation of competition in the retail electronic-commerce market. The International Center for Law & Economics (“ICLE”) is a nonprofit, nonpartisan global research and policy center founded with the goal of building the intellectual foundations for sensible, economically grounded policy. ICLE promotes the use of law & economics methodologies to inform public-policy debates and has longstanding expertise in the evaluation of competition law and policy. ICLE’s interest is to ensure that competition law remains grounded in clear rules, established precedent, a record of evidence, and sound economic analysis.

The Report stems from a procedure included in the Mexican Competition Act, known as “Investigations to Determine Essential Facilities or Barriers to Competition”. COFECE can initiate such investigations “when there are elements suggesting there are no effective competition conditions in a market.” The IA is responsible for issuing a preliminary investigative report and proposing corrective measures. COFECE’s Board of Commissioners can later adopt or reject the proposal.

Our comments respectfully suggest to COFECE Commissioners not to follow the recommendations of the IA concerning competition in the retail electronic-commerce market. While the Report is a laudable effort to understand the market and to protect the competition upon it—competition that has been beneficial to Mexican consumers—its conclusions and recommendations do not follow the evidence and the generally accepted methods and principles of Antitrust laws and best practices.

In first place, under the Mexican Competition Act, investigations should aim to eliminate only “restrictions to the efficient operation of markets”, the purpose of According to publicly available information, however, Amazon and Mercado Libre (MeLi), the two companies identified as “dominant” in the report, owe their success to consumer preferences and trust, rather than “barriers to competition”. Indeed, if these were present, they would lead to consumer dissatisfaction that is simply not the case here. The report also ignores the consumer benefits provided by Amazon and MeLi’s business models (i.e., cheaper products and services, fast delivery, easier access to information to compare products, etc.).

Second, the Report defines an unreasonably narrow relevant market that includes only “online marketplaces in multiple product categories and operating at the national level”. This market definition ignores other online retailers (like Shein or Temu) because they sell a narrower selection of goods?, e-commerce aggregators (like Google Shopping) because they are merely intermediaries that connect buyers and sellers, seller-owned websites (like Apple or Adidas) because they do not sell as many distinct product categories, as well as brick-and-mortar stores. By artificially narrowing the market in this way, the report drastically overstates Amazon and MeLi’s market shares.

Third, this gerrymandered relevant market leads to an artificial finding that Amazon and MeLi are “dominant” marketplaces—a key requirement for subsequent enforcement. This finding is problematic because the Report considers any costs faced by new entrants as “barriers to entry” that insulate the two marketplaces from competition. As we argue below, however, these “barriers” are merely regular business costs that do not prevent new players from entering. To wit, the record shows that new firms regularly enter the market.

Finally, the proposed remedies would harm rather than benefit consumers. The Report suggests forcing Amazon and MeLi to separate their streaming services (like Amazon Prime) from their loyalty programs. This would hurt consumers who currently enjoy bundled benefits at a lower price. Additionally, requiring the platforms to interoperate with other logistics providers would stifle innovation and investment as these platforms wouldn’t reap the benefits of their digital infrastructure. This mandated interoperability could also harm consumers who may attribute delivery-related failings to the marketplaces rather than logistics providers responsible for them, thereby creating a standard free-rider problem.

I. Introduction

The Report has been issued in the context of a procedure contemplated in Article 94 of the Mexican Competition Act, known as “Investigations to Determine Essential Facilities or Barriers to Competition”. According to this provision, COFECE shall initiate an investigation “when there are elements suggesting there are no effective competition conditions in a market”. The investigation should aim to determine the existence of “barriers to competition and free market access” or of “essential facilities”.

An IA is responsible for issuing a preliminary investigative report and to propose corrective measures. The Report must identify the market subject to the investigation with the purpose of allowing any person to provide elements during the investigation. Once the investigation is finished, the IA shall issue a Report, including corrective measures deemed necessary to eliminate the restrictions to the efficient operation of the market. Economic agents potentially affected by corrective measures proposed have the opportunity to comment and provide evidence. COFECE’s Board of Commissioners can later adopt or reject the proposals.

We understand and commend COFECE’s concerns for competition in the marketplaces market, but any investigation should aim to eliminate “restrictions to the efficient operation of markets”, the purpose of the Mexican Competition Act, according to its Article 2[2]. The conclusions and recommendations of the Report do not appear to consider the efficiency of the leading marketplaces, which may explain why consumers routinely choose them over rivals.

Indeed, according to publicly available information, Amazon and MeLi, the two companies identified as “dominant” in the report, owe their success to consumer preferences and trust.  According to one source[3], for instance:

The popularity of the Amazon marketplace in Mexico is largely based on customer satisfaction. Amazon is the second most appreciated e-commerce platform in Mexico, according to a Kantar survey, with a satisfaction index of 8.5 out of 10. Consumer feedback is also essential to the success of the Amazon marketplace, as it allows buyers to make successful purchases. Consumer reviews are also essential to the success of the Amazon marketplace, allowing buyers to make informed purchases. Good reviews highlight Amazon’s speed and reliability [emphasis added].

According to a study published by the Federal Institute of Telecommunications (IFT, after its Spanish acronym) about the use of digital platforms during the Covid-19 pandemic, 75.8% of users claim to be satisfied or very satisfied with the applications and webpages they use to buy online. Moreover, MeLi and Amazon were the most mentioned platforms with 67.3% and 30.3% of mentions, respectively.[4]

The report also appears to ignore the consumer benefits provided by Amazon MeLi’s business models (i.e., cheaper products and services, fast delivery, easier access to information to compare products, etc.).

The Report finds preliminary evidence to support the notion that “there are no conditions of effective competition in the Relevant Market of Sellers and in the Relevant Market of Buyers,” as well as the existence of “three Barriers to Competition” that generate restrictions on the efficient functioning of said markets.

The alleged barriers consist of:

1. “Artificiality” in some components of the marketplaces’ loyalty programs (services embedded in loyalty programs that—without being directly linked to the marketplace’s ability to carry out or facilitate transactions between buyers and sellers, and coupled with “network effects”—affect buyers’ behavior);

2. “Buy Box opacity”[5] (sellers on the marketplaces don’t have access to the ways that Amazon and MeLi choose the products placed into the Buy Box); and

1. “Logistic solutions foreclosure,” because Amazon and MeLi don’t allow all logistics providers to access their platforms’ Application Programming Interfaces (APIs), but rather bundle marketplace services with their own fulfillment services.

To eliminate these alleged barriers, the Report proposes three remedies, to be applied to Amazon and MeLi:

1. An obligation to “disassociate” streaming services from membership and/or loyalty programs (e.g., Amazon Prime), as well as any other service unrelated to use of the marketplace (e.g., games and music, among others);
2. An obligation to carry out all actions that are “necessary and sufficient” to allow sellers to freely adjust their commercial strategies with full knowledge of the Buy Box selection processes; and
3. An obligation to allow third-party logistics companies to integrate into the platform through their respective APIs, and to ensure that Buy Box selection doesn’t depend on the choice of logistics provider unless it affects “efficiency and performance criteria.”

We disagree with the findings and recommendations of the Report for the reasons stated below:

II. An Unreasonably Narrow Market Definition

Rather than an “abuse of dominance” procedure, the market investigation that led to the report was a “quasi-regulatory procedure.” But the wording of Article 94 of the Mexican Federal Economic Competition Act (under which the investigation was authorized) strongly suggests that COFECE has to establish (not simply assert) an “absence of effective competition.” This would entail either that there is a “market failure” that impedes competition, or that there is an economic agent with a dominant position. The report unconvincingly tries to show the latter.

To determine if any given company has a “dominant position” (monopoly power), competition agencies must first define a “relevant market” in which the challenged conduct or business model has an effect. Although it is common for antitrust enforcers to define relevant markets narrowly (often, the smaller the market, the easier it is to find that the hypothetical monopolist is, in fact, a monopolist), we think the Report goes too far in the case at hand.

The Report appears to follow the bad example of its American counterpart, the Federal Trade Commission (FTC). As Geoffrey Manne explains in an Issue Brief about the FTC’s recent monopolization complaint[6] against Amazon the agency:

The FTC’s complaint against Amazon describes two relevant markets in which anticompetitive harm has allegedly occurred: (1) the “online superstore market” and (2) the “online marketplace services market.”

… the FTC’s complaint limits the online-superstore market to online stores only, and further limits it to stores that have an “extensive breadth and depth” of products. The latter means online stores that carry virtually all categories of products (“such as sporting goods, kitchen goods, apparel, and consumer electronics”) and that also have an extensive variety of brands within each category (such as Nike, Under Armor, Adidas, etc.). In practice, this definition excludes leading brands’ private channels (such as Nike’s online store), as well as online stores that focus on a particular category of goods (such as Wayfair’s focus on furniture). It also excludes the brick-and-mortar stores that still account for the vast majority of retail transactions. Firms with significant online and brick-and-mortar sales might count, but only their online sales would be considered part of the market. [7]

The Report does something similar. It defines two relevant markets;

1. Sellers Relevant Market: consists of the marketplace service for sellers, with a national geographical dimension.
2. Buyers Relevant Market: consists of the service of marketplaces and multi-category online stores for buyers in the national territory, which includes marketplace business models (hybrid and non-hybrid) and online stores with multiple categories of products.

Both markets, however, are defined in an unreasonably narrow way. By alleging that large online marketplaces “have positioned themselves as an important choice,” the agency ignores competition from other online and offline retailers. The Report ignores other e-commerce platforms—like China’s Shein[8] and Temu[9]—that have gained both popularity and advertising-market share. The report also neglects to mention e-commerce aggregators like Google Shopping, which allow consumers to search for almost any product, compare them, and find competitive offers; as well as competition from e-commerce websites owned by sellers, such as Apple or Adidas.

This exclusion seems wrong. To compete with and “online superstores”, online stores do not need the scope of products that Amazon or MeLi have, because “consumers buy products, not store types”[10]:

Indeed, part of the purported advantage of online shopping—when it’s an advantage—is that consumers don’t have to bundle purchases together to minimize the transaction costs of physically visiting a brick-and-mortar retailer. Meanwhile, another part of the advantage of online shopping is the ease of comparison shopping: consumers don’t even have to close an Amazon window on their computers to check alternatives, prices, and availability elsewhere. All of this undermines the claim that one-stop shopping is a defining characteristic of the alleged market.[11]

The Report also appears to ignore the competitive constraints imposed by brick-and-mortar retailers, especially if Amazon or MeLi tried to exploit their market power. Of course, how many consumers might switch, and the extent to which that would affect the marketplaces, are empirical questions. But there is no question that some consumers might switch. In that respect, it is important to remember that competition takes place on the margins. Accordingly, it is not necessary for all consumers to switch to affect a company’s sales and profits.

The report does mention selling through social media but does not include such sales in the relevant market. We think that social media should as a sales channel should be considered as reasonable substitute for Amazon and MeLi, considering the fact that 85% of small and medium enterprises turned to Facebook, Instagram, and WhatsApp during the Covid-19 pandemic to advertise and sell their products.[12] The Commercial Guide for Mexico published by the U.S. Department of Commerce’s International Trade Administration reports that “Mexican buyers are highly influenced by social networks when making purchases. Forty-three percent of eCommerce buyers have bought via Conversational Commerce or C-commerce (selling via Facebook or WhatsApp), and 29 percent through “lives” or livestreams”.[13]

There is also empirical evidence that Amazon not only competes, but competes intensively with other distribution channels, and has a net-positive welfare effect on Mexican consumers. A 2022 paper[14] found that:

1. E-commerce and brick-and-mortar retailers in Mexico operate in a single, highly competitive retail market; and
2. Amazon’s entry has generated a significant pro-competitive effect by reducing brick-and-mortar retail prices and increasing product selection for Mexican consumers.

The paper finds the market entry of products sold and delivered by Amazon gave rise to price reductions of up to 28%.[15] In light of this evidence, we think that is wrong to assume that marketplaces like Amazon and MeLi do not compete with other retailers. The latter should thus be included in the relevant market.

As if this narrow definition were not enough, the report conflates Amazon and MeLi’s market shares, to conclude that, together, both hold more than 85% of the sales and transactions in the Relevant Seller Market during the period analyzed and the Herfindahl-Hirschman Index (HHI) exceeds two thousand points (therefore, the market is highly concentrated). Likewise, in the “Relevant Buyers Market,” the HHI was estimated, for 2022, at 1,614 units and the main three participants concentrate 61% (sixty-one percent) of the market. In both markets, the other participants have a significantly smaller share.

But why combine the market share of Amazon and MeLi, as if they were acting as a single firm? Given the IO’s market definition, it must at least be the case that Amazon and MeLi at least competing with each other. The market’s continuous growth and the evolution of the companies’ respective market shares indicate that they do. A news article from 2020, for instance, reports that:

Supermarkets, department stores and digital-native chains have a common goal: to be the one that captures the most market in electronic commerce in Mexico. In this battle, Amazon and Mercado Libre take the lead, as they are the two firms that concentrate almost a quarter of the total market in this area.

At the end of 2019, Amazon had a market share of 13.4%, which placed it ahead of other competitors. That same year, Mercado Libre was with 11.4%.[16]

Also inconsistent with the hypothesis of a market with “barriers to competition” is the fact that the e-commerce market is continuously growing (and adding market players) in Mexico, which is now the second-largest e-commerce market in Latin America.[17]

It is only on the basis of this distorted depiction of the market that the Report reaches the conclusion that Amazon and MeLi have “the power to fix prices” (another form of saying “monopoly power”). Given what precedes, that conclusion should be rejected.

III. An Unwarranted Finding of a ‘Dominant Position’

Even if one accepts the Report’s market definition, and Amazon and MeLi thus have a significant market share, both firms could still face competition from new entrants, attracted to the market by the higher prices (or other “exploitative” conditions) charged to consumers. According to the Report, alas, there are various barriers to hinder “the entry and expansion” in both relevant markets. Among them, the Report mentions, for instance:

1. Barriers to entry related to the high amounts of investment for the development of the marketplace, as well as for the development of technological tools integrated into it…. In addition, high investment amounts are required related to the development of logistics infrastructure and in working capital related to funds necessary to cover operating expenses, inventories, accounts receivable and other current liabilities; and
2. Barriers to entry related to considerable investments in advertising, marketing and public relations. To attract a significant number of buyers and sellers to the platform that guarantees the success of the business, it is imperative to have a well-positioned, recognized brand with a good reputation.

Contrary to what the report claims, however, these are costs, not “barriers to entry.” As Richard Posner convincingly explained, the term “barrier to entry” is commonly used to describe any obstacle or cost faced by entrants. [18] But by this definition (embraced by the Report, apparently), any cost is a barrier to entry. Relying on George Stigler’s more precise definition, Posner suggested defining a barrier to entry as “a condition that imposes higher long-run costs of production on a new entrant than are borne by the firms already in the market.”[19] In other words, properly understood, a barrier to entry is a cost borne by new entrants that was not borne by incumbents.

The authority’s definition of barriers to entry is also at odds with the definition given by the Section IV of Article 3 of the Mexican Competition Act, according to which a barrier to competition is:

Any structural market characteristic, act or deed performed by Economic Agents with the purpose or effect of impeding access to competitors or limit their ability to compete in the markets; which impedes or distorts the process of competition and free market access, as well as any legal provision issued by any level of government that unduly impedes or distorts the process of competition and free market access.

Of course, Amazon and MeLi have some advantages over other firms in terms of their infrastructure, know-how, scale, and goodwill. But those advantages didn’t fall from the sky. Amazon and MeLi built them over time, investing (and continuing to invest) often enormous amounts to do so. Even “network effects” often considered as an inevitable source of monopoly, are not a definite obstacle to competition. As Evans and Schmalensee, have pointed out:

Systematic research on online platforms by several authors, including one of us, shows considerable churn in leadership for online platforms over periods shorter than a decade. Then there is the collection of dead or withered platforms that dot this sector, including Blackberry and Windows in smartphone operating systems, AOL in messaging, Orkut in social networking, and Yahoo in mass online media.^[20]

The notion that Amazon and MeLi are shielded by barriers to entry is also contradicted by the entry of new rivals, such as Shein and Temu.

As explained above, the Report also erroneously conflates the market shares of Mercado Libre and Amazon, to reach a combined market share of 85% (eighty-five percent) of sales and transactions in the Sellers Relevant Market; and then combines the market share of the main three market participants in the Buyers Relevant Market to reach a market share of 61% (sixty-one percent) of the market. This is highly problematic as those firms are not a single economic entity, they thus presumably compete against each other.

If anything, the market shares produced by the Report only lead to a high HHI, which in turn shows that the market is “highly concentrated” (if one accepts the Report’s narrow market definition). But concentration is a poor proxy for market power. Economists have been studying the relationship between concentration and various potential indicia of anticompetitive effects—price, markup, profits, rate of return, etc.—for decades, and the empirical evidence is more than enough to say that concentration could lead to competition problems. ^[21] It is not per se evidence of a lack of competition, let alone a dominant position.

As Chad Syverson recently summarized:

Perhaps the deepest conceptual problem with concentration as a measure of market power is that it is an outcome, not an immutable core determinant of how competitive an industry or market is… As a result, concentration is worse than just a noisy barometer of market power. Instead, we cannot even generally know which way the barometer is oriented.[22]

IV. The Proposed Remedies Would Harm, Rather than Benefit, Consumers

Even if one accepts the Report’s suggested market definition and its assessment of market power, the report’s proposed remedies—which could be summarized as the mandated unbundling of Amazon’s and MeLi’s streaming services from their loyalty programs (like Amazon’s Prime) and to make (at least part of) their platforms “interoperable” with other logistic services—would harm consumers, rather than benefit them.

Amazon Prime, for instance, provides consumers with many attractive benefits: access to video and music streaming; special deals and discounts; and last, but not least, two-day free shipping. According to the Report, “this is an artificial strategy that attracts and retains buyers and, at the same time, hinders buyers and sellers from using alternative marketplaces.”

It’s not entirely clear what “artificial” means in this context, but it appears to imply something outside of the bounds of “normal” competition. Yet what the Report describes is the very definition of competition. Firms competing in a market always choose to combine a “bundle” of features into a single product. They to some extent “bet” on a bundle of features (functionality, materials, terms and conditions) that imply assuming some costs, that they later offer at a given price, that may be met by willing customers (or not). Even with imperfect information, markets (that is, sellers and customers) are the best qualified agents to “decide” the appropriate level of “bundling” on a product, not competition agencies or courts.

A mandate to unbundle streaming services would degrade the online experience of consumers, who would instead have to contract and pay for those services separately.[23] The independent provision of such services would not benefit from Amazon’s or MeLi’s economies of scale and scope and would, therefore, be more expensive. And providing more benefits for consumers at a given price is what we want competitors to do. Treating consumer benefit as a harm turns competition enforcement—and, indeed, the very notion of competition itself—on its head.

The report also proposes to open the Buy Box and modifying its rules so as to be neutral to all logistics providers. This effectively amounts to treating Amazon and MeLi as “common carriers,” like regulators did with telephone networks from the 20^th century onwards. Unfortunately, this classification and the rules that follow from it (neutrality and price regulation, among others) was designed for markets with natural monopolies—where competition is not possible or even undesirable[24]—but there is no evidence to suggest this is the case in the case at hand. Instead, Digital platform markets are far more competitive. Given this, common-carrier rules would only foster free riding and dampen incentives to invest and innovate (for both incumbents and new entrants). Sellers and logistics providers have many other options to access consumers. There is no economic or legal justification to mandate their access to Amazon or MeLi’s platforms.

In sum, the Report’s flawed findings lead to even worse remedies. Such remedies would neither promote competition in Mexico nor benefit consumers.

Being in this box is an advantage for the seller because it not only highlights its product, but also makes the payment process easier. This is, of course, also an advantage for consumers, who can find and buy products faster.

In this “Age of the Administrative State,” federal agencies have incredible latitude to impose policies without much direction or input from Congress. President Barack Obama fully pulled off the mask in 2014, when he announced “[w]e are not just going to be waiting for legislation,” declaring “I’ve got a pen, and I’ve got a phone.” Subsequent presidents have similarly discovered that they had pens and phones, too.

The big news in telecommunications policy last week wasn’t really news at all—the Federal Communications Commission (FCC) released its proposed rules to classify broadband internet under Title II of the Communications Act. Supporters frame the proposed rules as “net neutrality,” but those provisions—a ban on blocking, throttling, or engaging in paid or affiliated-prioritization arrangements—actually comprise just a small part of the 435-page document.
