App Stores as Public Utilities?

Giuseppe Colangelo and Oscar Borgogno —  19 January 2022

In a new paper, Giuseppe Colangelo and Oscar Borgogno investigate whether antitrust policy is sufficiently flexible to keep up with the dynamics of digital app stores, and whether regulatory interventions are required in order to address their unique features. The authors summarize their findings in this blog post.

App stores are at the forefront of policy debates surrounding digital markets. The gatekeeping position of Apple and Google in the App Store and Google Play Store, respectively, and related concerns about the companies’ rule-setting and dual role, have been the subject of market studies launched by the Australian Competition and Consumer Commission (ACCC), the Netherlands Authority for Consumers & Markets (ACM), the U.K. Competition and Markets Authority (CMA), the Japan Federal Trade Commission (JFTC), and the U.S. House of Representatives.

Likewise, the terms and conditions for accessing app stores—such as in-app purchasing rules, restrictions on freedom of choice for smartphone payment apps, and near field communication (NFC) limitations—face scrutiny from courts and antitrust authorities around the world.

Finally, legislative initiatives envisage obligations explicitly addressed to app stores. Notably, the European Digital Markets Act (DMA) and some U.S. bills (e.g., the American Innovation and Choice Online Act and the Open App Markets Act, both of which are scheduled to be marked up Jan. 20 by the Senate Judiciary Committee) prohibit designated platforms from, for example: discriminating among users by engaging in self-preferencing and applying unfair access conditions; preventing users from sideloading and uninstalling pre-installed apps; impeding data portability and interoperability; or imposing anti-steering provisions. Likewise, South Korea has recently prohibited app-store operators in dominant market positions from forcing payment systems upon content providers and inappropriately delaying the review of, or deleting, mobile content from app markets.

Despite their differences, these international legislative initiatives do share the same aims and concerns. By and large, they question the role of competition law in the digital economy. In the case of app stores, these regulatory interventions attempt to introduce a neutrality regime, with the aim of increasing contestability, facilitating the possibility of switching by users, tackling conflicts of interests, and addressing imbalances in the commercial relationship. Ultimately, these proposals would treat online platforms as akin to common carriers or public utilities.

All of these initiatives assume antitrust is currently falling, because competition rules apply ex post and require an extensive investigation on a case-by-case basis. But is that really the case?

Platform and Device Neutrality Regime

Focusing on the content of the European, German, and U.S. legislative initiatives, the neutrality regime envisaged for app stores would introduce obligations in terms of both device and platform neutrality. The former includes provisions on app uninstalling, sideloading, app switching, access to technical functionality, and the possibility of changing default settings.  The latter entail data portability and interoperability obligations, and the ban on self-preferencing, Sherlocking, and unfair access conditions.

App Store Obligations: Comparison of EU, German, and U.S. Initiatives

Antitrust v. Regulation

Despite the growing consensus regarding the need to rely on ex ante regulation to govern digital markets and tackle the practices of large online platforms, recent and ongoing antitrust investigations demonstrate that standard competition law still provides a flexible framework to scrutinize several practices sometimes described as new and peculiar to app stores.

This is particularly true in Europe, where the antitrust framework grants significant leeway to antitrust enforcers relative to the U.S. scenario, as illustrated by the recent Google Shopping decision.

Indeed, considering legislative proposals to modernize antitrust law and to strengthen its enforcement, the U.S. House Judiciary Antitrust Subcommittee, along with some authoritative scholars, have suggested emulating the European model—imposing particular responsibility on dominant firms through the notion of abuse of dominant position and overriding several Supreme Court decisions in order to clarify the prohibitions on monopoly leveraging, predatory pricing, denial of essential facilities, refusals to deal, and tying.

By contrast, regulation appears better suited to support interventions intended to implement industrial-policy objectives. This applies, in particular, to provisions prohibiting app stores from impeding or restricting sideloading, app uninstalling, the possibility of choosing third-party apps and app stores as defaults, as well as provisions that would mandate data portability and interoperability.

However, such regulatory proposals may ultimately harm consumers. Indeed, by questioning the core of digital platform business models and affecting their governance design, these interventions entrust public authorities with mammoth tasks that could ultimately jeopardize the profitability of app-store ecosystems. They also overlook the differences that may exist between the business models of different platforms, such as Google and Apple’s app stores.

To make matters worse, the  difficulties encountered by regulators that have imposed product-design remedies on firms suggest that regulators may struggle to craft feasible and effective solutions. For instance, when the European General Court found that Google favored its own services in the Google Shopping case, it noted that this finding rested on the differential positioning and display of Shopping Units when compared to generic results. As a consequence, it could be argued that Google’s proposed auction remedy (whereby Google would compete with rivals for Shopping box placement) is compliant with the Court’s ruling because there is no dicrimination, regardless of the fact that Google might ultimately outbid its rivals (see here).

Finally, the neutrality principle cannot be transposed perfectly to all online platforms. Indeed, the workings of the app-discovery and distribution markets differ from broadband networks, as rankings and mobile services by definition involve some form of continuous selection and differentiated treatment to optimize the mobile-customer experience.

For all these reasons, our analysis suggests that antitrust law provides a less intrusive and more individualized approach, which would eventually benefit consumers by safeguarding quality and innovation.

The market realities that undermine the antitrust case against Google

Geoffrey Manne —  26 November 2012

As the Google antitrust discussion heats up on its way toward some culmination at the FTC, I thought it would be helpful to address some of the major issues raised in the case by taking a look at what’s going on in the market(s) in which Google operates. To this end, I have penned a lengthy document — The Market Realities that Undermine the Antitrust Case Against Google — highlighting some of the most salient aspects of current market conditions and explaining how they fit into the putative antitrust case against Google.

While not dispositive, these “realities on the ground” do strongly challenge the logic and thus the relevance of many of the claims put forth by Google’s critics. The case against Google rests on certain assumptions about how the markets in which it operates function. But these are tech markets, constantly evolving and complex; most assumptions (and even “conclusions” based on data) are imperfect at best. In this case, the conventional wisdom with respect to Google’s alleged exclusionary conduct, the market in which it operates (and allegedly monopolizes), and the claimed market characteristics that operate to protect its position (among other things) should be questioned.

The reality is far more complex, and, properly understood, paints a picture that undermines the basic, essential elements of an antitrust case against the company.

The document first assesses the implications for Market Definition and Monopoly Power of these competitive realities. Of note:

  • Users use Google because they are looking for information — but there are lots of ways to do that, and “search” is not so distinct that a “search market” instead of, say, an “online information market” (or something similar) makes sense.
  • Google competes in the market for targeted eyeballs: a market aimed to offer up targeted ads to interested users. Search is important in this, but it is by no means alone, and there are myriad (and growing) other mechanisms to access consumers online.
  • To define the relevant market in terms of the particular mechanism that prevails to accomplish the matching of consumers and advertisers does not reflect the substitutability of other mechanisms that do the same thing but simply aren’t called “search.”
  • In a world where what prevails today won’t — not “might not,” but won’t — prevail tomorrow, it is the height of folly (and a serious threat to innovation and consumer welfare) to constrain the activities of firms competing in such an environment by pigeonholing the market.
  • In other words, in a proper market, Google looks significantly less dominant. More important, perhaps, as search itself evolves, and as Facebook, Amazon and others get into the search advertising game, Google’s strong position even in the overly narrow “search” market looks far from unassailable.

Next I address Anticompetitive Harm — how the legal standard for antitrust harm is undermined by a proper understanding of market conditions:

  • Antitrust law doesn’t require that Google or any other large firm make life easier for competitors or others seeking to access resources owned by these firms.
  • Advertisers are increasingly targeting not paid search but rather social media to reach their target audiences.
  • But even for those firms that get much or most of their traffic from “organic” search, this fact isn’t an inevitable relic of a natural condition over which only the alleged monopolist has control; it’s a business decision, and neither sensible policy nor antitrust law is set up to protect the failed or faulty competitor from himself.
  • Although it often goes unremarked, paid search’s biggest competitor is almost certainly organic search (and vice versa). Nextag may complain about spending money on paid ads when it prefers organic, but the real lesson here is that the two are substitutes — along with social sites and good old-fashioned email, too.
  • It is incumbent upon critics to accurately assess the “but for” world without the access point in question. Here, Nextag can and does use paid ads to reach its audience (and, it is important to note, did so even before it claims it was foreclosed from Google’s users). But there are innumerable other avenues of access, as well. Some may be “better” than others; some that may be “better” now won’t be next year (think how links by friends on Facebook to price comparisons on Nextag pages could come to dominate its readership).
  • This is progress — creative destruction — not regress, and such changes should not be penalized.

Next I take on the perennial issue of Error Costs and the Risks of Erroneous Enforcement arising from an incomplete and inaccurate understanding of Google’s market:

  • Microsoft’s market position was unassailable . . . until it wasn’t — and even at the time, many could have told you that its perceived dominance was fleeting (and many did).
  • Apple’s success (and the consumer value it has created), while built in no small part on its direct competition with Microsoft and the desktop PCs which run it, was primarily built on a business model that deviated from its once-dominant rival’s — and not on a business model that the DOJ’s antitrust case against the company either facilitated or anticipated.
  • Microsoft and Google’s other critic-competitors have more avenues to access users than ever before. Who cares if users get to these Google-alternatives through their devices instead of a URL? Access is access.
  • It isn’t just monopolists who prefer not to innovate: their competitors do, too. To the extent that Nextag’s difficulties arise from Google innovating, it is Nextag, not Google, that’s working to thwart innovation and fighting against dynamism.
  • Recall the furor around Google’s purchase of ITA, a powerful cautionary tale. As of September 2012, Google ranks 7th in visits among metasearch travel sites, with a paltry 1.4% of such visits. Residing at number one? FairSearch founding member, Kayak, with a whopping 61%. And how about FairSearch member Expedia? Currently, it’s the largest travel company in the world, and it has only grown in recent years.

The next section addresses the essential issue of Barriers to Entry and their absence:

  • One common refrain from Google’s critics is that Google’s access to immense amounts of data used to increase the quality of its targeting presents a barrier to competition that no one else can match, thus protecting Google’s unassailable monopoly. But scale comes in lots of ways.
  • It’s never been the case that a firm has to generate its own inputs into every product it produces — and there is no reason to suggest search/advertising is any different.
  • Meanwhile, Google’s chief competitor, Microsoft, is hardly hurting for data (even, quite creatively, culling data directly from Google itself), despite its claims to the contrary. And while regulators and critics may be looking narrowly and statically at search data, Microsoft is meanwhile sitting on top of copious data from unorthodox — and possibly even more valuable — sources.
  • To defend a claim of monopolization, it is generally required to show that the alleged monopolist enjoys protection from competition through barriers to entry. In Google’s case, the barriers alleged are illusory.

The next section takes on recent claims revolving around The Mobile Market and Google’s position (and conduct) there:

  • If obtaining or preserving dominance is simply a function of cash, Microsoft is sitting on some $58 billion of it that it can devote to that end. And JP Morgan Chase would be happy to help out if it could be guaranteed monopoly returns just by throwing its money at Bing. Like data, capital is widely available, and, also like data, it doesn’t matter if a company gets it from selling search advertising or from selling cars.
  • Advertisers don’t care whether the right (targeted) user sees their ads while playing Angry Birds or while surfing the web on their phone, and users can (and do) seek information online (and thus reveal their preferences) just as well (or perhaps better) through Wikipedia’s app as via a Google search in a mobile browser.
  • Moreover, mobile is already (and increasingly) a substitute for the desktop. Distinguishing mobile search from desktop search is meaningless when users use their tablets at home, perform activities that they would have performed at home away from home on mobile devices simply because they can, and where users sometimes search for places to go (for example) on mobile devices while out and sometimes on their computers before they leave.
  • Whatever gains Google may have made in search from its spread into the mobile world is likely to be undermined by the massive growth in social connectivity it has also wrought.
  • Mobile is part of the competitive landscape. All of the innovations in mobile present opportunities for Google and its competitors to best each other, and all present avenues of access for Google and its competitors to reach consumers.

The final section Concludes.

The lessons from all of this? There are two. First, these are dynamic markets, and it is a fool’s errand to identify the power or significance of any player in these markets based on data available today — data that is already out of date between the time it is collected and the time it is analyzed.

Second, each of these developments has presented different, novel and shifting opportunities and challenges for firms interested in attracting eyeballs, selling ad space and data, earning revenue and obtaining market share. To say that Google dominates “search” or “online advertising” misses the mark precisely because there is simply nothing especially antitrust-relevant about either search or online advertising. Because of their own unique products, innovations, data sources, business models, entrepreneurship and organizations, all of these companies have challenged and will continue to challenge the dominant company — and the dominant paradigm — in a shifting and evolving range of markets.

Perhaps most important is this:

Competition with Google may not and need not look exactly like Google itself, and some of this competition will usher in innovations that Google itself won’t be able to replicate. But this doesn’t make it any less competitive.  

Competition need not look identical to be competitive — that’s what innovation is all about. Just ask those famous buggy whip manufacturers.

Should the FTC Sue Google Over Search? A TechFreedom Debate This Friday

Geoffrey Manne —  25 September 2012

I will be speaking at a lunch debate in DC hosted by TechFreedom on Friday, September 28, 2012, to discuss the FTC’s antitrust investigation of Google. Details below.

TechFreedom will host a livestreamed, parliamentary-style lunch debate on Friday September 28, 2012, to discuss the FTC’s antitrust investigation of Google.   As the company has evolved, expanding outward from its core search engine product, it has come into competition with a range of other firms and established business models. This has, in turn, caused antitrust regulators to investigate Google’s conduct, essentially questioning whether the company’s success obligates it to treat competitors neutrally. James Cooper, Director of Research and Policy for the Law and Economics Center at George Mason University School of Law, will moderate a panel of four distinguished commenters to discuss the question, “Should the FTC Sue Google Over Search?”  

Arguing “Yes” will be:

Arguing “No” will be:

When:
Friday, September 28, 2012
12:00 p.m. – 2:00 p.m.

Where:
The Monocle Restaurant
107 D Street Northeast
Washington, DC 20002

RSVP here. The event will be livestreamed here and you can follow the conversation on Twitter at #GoogleFTC.

For those viewing by livestream, we will watch for questions posted to Twitter at the #GoogleFTC hashtag and endeavor, as possible, to incorporate them into the debate.

Google Isn’t ‘Leveraging Its Dominance,’ It’s Fighting To Avoid Obsolescence

Geoffrey Manne —  12 March 2012

Six months may not seem a great deal of time in the general business world, but in the Internet space it’s a lifetime as new websites, tools and features are introduced every day that change where and how users get and share information. The rise of Facebook is a great example: the social networking platform that didn’t exist in early 2004 filed paperwork last month to launch what is expected to be one of the largest IPOs in history. To put it in perspective, Ford Motor went public nearly forty years after it was founded.

This incredible pace of innovation is seen throughout the Internet, and since Google’s public disclosure of its Federal Trade Commission antitrust investigation just this past June, there have been many dynamic changes to the landscape of the Internet Search market. And as the needs and expectations of consumers continue to evolve, Internet search must adapt – and quickly – to shifting demand.

One noteworthy development was the release of Siri by Apple, which was introduced to the world in late 2011 on the most recent iPhone. Today, many consider it the best voice recognition application in history, but its potential really lies in its ability revolutionize the way we search the Internet, answer questions and consume information. As Eric Jackson of Forbes noted, in the future it may even be a “Google killer.”

Of this we can be certain: Siri is the latest (though certainly not the last) game changer in Internet search, and it has certainly begun to change people’s expectations about both the process and the results of search. The search box, once needed to connect us with information on the web, is dead or dying. In its place is an application that feels intuitive and personal. Siri has become a near-indispensible entry point, and search engines are merely the back-end. And while a new feature, Siri’s expansion is inevitable. In fact, it is rumored that Apple is diligently working on Siri-enabled televisions – an entirely new market for the company.

The past six months have also brought the convergence of social media and search engines, as first Bing and more recently Google have incorporated information from a social network into their search results. Again we see technology adapting and responding to the once-unimagined way individuals find, analyze and accept information. Instead of relying on traditional, mechanical search results and the opinions of strangers, this new convergence allows users to find data and receive input directly from people in their social world, offering results curated by friends and associates.

As Social networks become more integrated with the Internet at large, reviews from trusted contacts will continue to change the way that users search for information. As David Worlock put it in a post titled, “Decline and Fall of the Google Empire,” “Facebook and its successors become the consumer research environment. Search by asking someone you know, or at least have a connection with, and get recommendations and references which take you right to the place where you buy.” The addition of social data to search results lends a layer of novel, trusted data to users’ results. Search Engine Land’s Danny Sullivan agreed writing, “The new system will perhaps make life much easier for some people, allowing them to find both privately shared content from friends and family plus material from across the web through a single search, rather than having to search twice using two different systems.”It only makes sense, from a competition perspective, that Google followed suit and recently merged its social and search data in an effort to make search more relevant and personal.

Inevitably, a host of Google’s critics and competitors has cried foul. In fact, as Google has adapted and evolved from its original template to offer users not only links to URLs but also maps, flight information, product pages, videos and now social media inputs, it has met with a curious resistance at every turn. And, indeed, judged against a world in which Internet search is limited to “ten blue links,” with actual content – answers to questions – residing outside of Google’s purview, it has significantly expanded its reach and brought itself (and its large user base) into direct competition with a host of new entities.

But the worldview that judges these adaptations as unwarranted extensions of Google’s platform from its initial baseline, itself merely a function of the relatively limited technology and nascent consumer demand present at the firm’s inception, is dangerously crabbed. By challenging Google’s evolution as “leveraging its dominance” into new and distinct markets, rather than celebrating its efforts (and those of Apple, Bing and Facebook, for that matter) to offer richer, more-responsive and varied forms of information, this view denies the essential reality of technological evolution and exalts outdated technology and outmoded business practices.

And while Google’s forays into the protected realms of others’ business models grab the headlines, it is also feverishly working to adapt its core technology, as well, most recently (and ambitiously) with its “Google Knowledge Graph” project, aimed squarely at transforming the algorithmic guts of its core search function into something more intelligent and refined than its current word-based index permits. In concept, this is, in fact, no different than its efforts to bootstrap social network data into its current structure: Both are efforts to improve on the mechanical process built on Google’s PageRank technology to offer more relevant search results informed by a better understanding of the mercurial way people actually think.

Expanding consumer welfare requires that Google, like its ever-shifting roster of competitors, must be able to keep up with the pace and the unanticipated twists and turns of innovation. As The Economist recently said, “Kodak was the Google of its day,” and the analogy is decidedly apt. Without the drive or ability to evolve and reinvent itself, its products and its business model, Kodak has fallen to its competitors in the marketplace. Once revered as a powerhouse of technological innovation for most of its history, Kodak now faces bankruptcy because it failed to adapt to its own success. Having invented the digital camera, Kodak radically altered the very definition of its market. But by hewing to its own metaphorical ten blue links – traditional film – instead of understanding that consumer photography had come to mean something dramatically different, Kodak consigned itself to failure.

Like Kodak and every other technology company before it, Google must be willing and able to adapt and evolve; just as for Lewis Carol’s Red Queen, “here it takes all the running you can do, to keep in the same place.” Neither consumers nor firms are well served by regulatory policy informed by nostalgia. Even more so than Kodak, Google confronts a near-constantly evolving marketplace and fierce competition from unanticipated quarters. If regulators force it to stop running, the market will simply pass it by.

Investigating Search Bias: Measuring Edelman & Lockwood’s Failure to Measure Bias in Search

Josh Wright —  8 November 2011

Last week I linked to my new study on “search bias.”  At the time I noted I would have a few blog posts in the coming days discussing the study.  This is the first of those posts.

A lot of the frenzy around Google turns on “search bias,” that is, instances when Google references its own links or its own content (such as Google Maps or YouTube) in its search results pages.  Some search engine critics condemn such references as inherently suspect and almost by their very nature harmful to consumers.  Yet these allegations suffer from several crucial shortcomings.  As I’ve noted (see, e.g., here and here), these naked assertions of discrimination are insufficient to state a cognizable antitrust claim, divorced as they are from consumer welfare analysis.  Indeed, such “discrimination” (some would call it “vertical integration”) has a well-recognized propensity to yield either pro-competitive or competitively neutral outcomes, rather than concrete consumer welfare losses.  Moreover, because search engines exist in an incredibly dynamic environment, marked by constant innovation and fierce competition, we would expect different engines, utilizing different algorithms and appealing to different consumer preferences, to emerge.  So when search engines engage in product differentiation of this sort, there is no reason to be immediately suspicious of these business decisions.

No reason to be immediately suspicious – but there could, conceivably, be a problem.  If there is, we would want to see empirical evidence of it—of both the existence of bias, as well as the consumer harm emanating from it.  But one of the most notable features of this debate is the striking lack of empirical data.  Surprisingly little research has been done in this area, despite frequent assertions that own-content bias is commonly practiced and poses a significant threat to consumers (see, e.g., here).

My paper is an attempt to rectify this.  In the paper, I investigate the available data to determine whether and to what extent own-content bias actually occurs, by analyzing and replicating a study by Ben Edelman and Ben Lockwood (E&L) and conducting my own study of a larger, randomized set of search queries.

In this post I discuss my analysis and critique of E&L; in future posts I’ll present my own replication of their study, as well as the results of my larger study of 1,000 random search queries.  Finally, I’ll analyze whether any of these findings support anticompetitive foreclosure theories or are otherwise sufficient to warrant antitrust intervention.

E&L “investigate . . . [w]hether search engines’ algorithmic results favor their own services, and if so, which search engines do most, to what extent, and in what substantive areas.”  Their approach is to measure the difference in how frequently search engines refer to their own content relative to how often their rivals do so.

One note at the outset:  While this approach provides useful descriptive facts about the differences between how search engines link to their own content, it does little to inform antitrust analysis because Edelman and Lockwood begin with the rather odd claim that competition among differentiated search engines for consumers is a puzzle that creates an air of suspicion around the practice—in fact, they claim that “it is hard to see why results would vary . . . across search engines.”  This assertion, of course, is simply absurd.  Indeed, Danny Sullivan provides a nice critique of this claim:

It’s not hard to see why search engine result differ at all.  Search engines each use their own “algorithm” to cull through the pages they’ve collected from across the web, to decide which pages to rank first . . . . Google has a different algorithm than Bing.  In short, Google will have a different opinion than Bing.  Opinions in the search world, as with the real world, don’t always agree.

Moreover, this assertion completely discounts both the vigorous competitive product differentiation that occurs in nearly all modern product markets as well as the obvious selection effects at work in own-content bias (Google users likely prefer Google content).  This combination detaches E&L’s analysis from the consumer welfare perspective, and thus antitrust policy relevance, despite their claims to the contrary (and the fact that their results actually exhibit very little bias).

Several methodological issues undermine the policy relevance of E&L’s analysis.  First, they hand select 32 search queries and execute searches on Google, Bing, Yahoo, AOL and Ask.  This hand-selected non-random sample of 32 search queries cannot generate reliable inferences regarding the frequency of bias—a critical ingredient to understanding its potential competitive effects.  Indeed, E&L acknowledge their queries are chosen precisely because they are likely to return results including Google content (e.g., email, images, maps, video, etc.).

E&L analyze the top three organic search results for each query on each engine.  They find that 19% of all results across all five search engines refer to content affiliated with one of them.  They focus upon the first three organic results and report that Google refers to its own content in the first (“top”) position about twice as often as Yahoo and Bing refer to Google content in this position.  Additionally, they note that Yahoo is more biased than Google when evaluating the first page rather than only the first organic search result.

E&L also offer a strained attempt to deal with the possibility of competitive product differentiation among search engines.  They examine differences among search engines’ references to their own content by “compar[ing] the frequency with which a search engine links to its own pages, relative to the frequency with which other search engines link to that search engine’s pages.”  However, their evidence undermines claims that Google’s own-content bias is significant and systematic relative to its rivals’.  In fact, almost zero evidence of statistically significant own-content bias by Google emerges.

E&L find, in general, Google is no more likely to refer to its own content than other search engines are to refer to that same content, and across the vast majority of their results, E&L find Google search results are not statistically more likely to refer to Google content than rivals’ search results.

The same data can be examined to test the likelihood that a search engine will refer to content affiliated with a rival search engine.  Rather than exhibiting bias in favor of an engine’s own content, a “biased” search engine might conceivably be less likely to refer to content affiliated with its rivals.  The table below reports the likelihood (in odds ratios) that a search engine’s content appears in a rival engine’s results.

The first two columns of the table demonstrate that both Google and Yahoo content are referred to in the first search result less frequently in rivals’ search results than in their own.  Although Bing does not have enough data for robust analysis of results in the first position in E&L’s original analysis, the next three columns in Table 1 illustrate that all three engines’ (Google, Yahoo, and Bing) content appears less often on the first page of rivals’ search results than on their own search engine.  However, only Yahoo’s results differ significantly from 1.  As between Google and Bing, the results are notably similar.

E&L also make a limited attempt to consider the possibility that favorable placement of a search engine’s own content is a response to user preferences rather than anticompetitive motives.  Using click-through data, they find, unsurprisingly, that the first search result tends to receive the most clicks (72%, on average).  They then identify one search term for which they believe bias plays an important role in driving user traffic.  For the search query “email,” Google ranks its own Gmail first and Yahoo Mail second; however, E&L also find that Gmail receives only 29% of clicks while Yahoo Mail receives 54%.  E&L claim that this finding strongly indicates that Google is engaging in conduct that harms users and undermines their search experience.

However, from a competition analysis perspective, that inference is not sound.  Indeed, the fact that the second-listed Yahoo Mail link received the majority of clicks demonstrates precisely that Yahoo was not competitively foreclosed from access to users.  Taken collectively, E&L are not able to muster evidence of potential competitive foreclosure.

While it’s important to have an evidence-based discussion surrounding search engine results and their competitive implications, it’s also critical to recognize that bias alone is not evidence of competitive harm.  Indeed, any identified bias must be evaluated in the appropriate antitrust economic context of competition and consumers, rather than individual competitors and websites.  E&L’s analysis provides a useful starting point for describing how search engines differ in their referrals to their own content.  But, taken at face value, their results actually demonstrate little or no evidence of bias—let alone that the little bias they do find is causing any consumer harm.

As I’ll discuss in coming posts, evidence gathered since E&L conducted their study further suggests their claims that bias is prevalent, inherently harmful, and sufficient to warrant antitrust intervention are overstated and misguided.

Josh and I make the big leagues

Geoffrey Manne —  11 July 2011

Cited today by Gordon Crovitz in the Wall Street Journal:

Instead of letting consumers choose, other search companies including Microsoft are funding FairSearch.org to lobby regulators and politicians to stop what it calls “Google’s march toward an ‘unregulatable monopoly.'” Legal academics Geoffrey Manne and Joshua Wright wrote a recent article entitled “If Search Neutrality is the Answer, What’s the Question?” They ridicule the regulatory idea of a “Federal Search Commission” to monitor search providers. Google would lose its position if it gave its properties such as YouTube unfair preference in its search results. By serving consumers well, Google makes it harder for competitors, but that’s not an antitrust violation.

The whole thing is worth reading, of course.

Manne and Wright on Search Neutrality

Geoffrey Manne —  12 April 2011

Josh and I have just completed a white paper on search neutrality/search bias and the regulation of search engines.  The paper is this year’s first in the ICLE Antitrust & Consumer Protection White Paper Series:

If Search Neutrality Is the Answer, What’s the Question?


Geoffrey A. Manne

(Lewis & Clark Law School and ICLE)

and

Joshua D. Wright

(George Mason Law School & Department of Economics and ICLE)

In this paper we evaluate both the economic and non-economic costs and benefits of search bias. In Part I we define search bias and search neutrality, terms that have taken on any number of meanings in the literature, and survey recent regulatory concerns surrounding search bias. In Part II we discuss the economics and technology of search. In Part III we evaluate the economic costs and benefits of search bias. We demonstrate that search bias is the product of the competitive process and link the search bias debate to the economic and empirical literature on vertical integration and the generally-efficient and pro-competitive incentives for a vertically integrated firm to discriminate in favor of its own content. Building upon this literature and its application to the search engine market, we conclude that neither an ex ante regulatory restriction on search engine bias nor the imposition of an antitrust duty to deal upon Google would benefit consumers. In Part V we evaluate the frequent claim that search engine bias causes other serious, though less tangible, social and cultural harms. As with the economic case for search neutrality, we find these non-economic justifications for restricting search engine bias unconvincing, and particularly susceptible to the well-known Nirvana Fallacy of comparing imperfect real world institutions with romanticized and unrealistic alternatives

Search bias is not a function of Google’s large share of overall searches. Rather, it is a feature of competition in the search engine market, as evidenced by the fact that its rivals also exercise editorial and algorithmic control over what information is provided to consumers and in what manner. Consumers rightly value competition between search engine providers on this margin; this fact alone suggests caution in regulating search bias at all, much less with an ex ante regulatory schema which defines the margins upon which search providers can compete. The strength of economic theory and evidence demonstrating that regulatory restrictions on vertical integration are costly to consumers, impede innovation, and discourage experimentation in a dynamic marketplace support the conclusion that neither regulation of search bias nor antitrust intervention can be justified on economic terms. Search neutrality advocates touting the non-economic virtues of their proposed regime should bear the burden of demonstrating that they exist beyond the Nirvana Fallacy of comparing an imperfect private actor to a perfect government decision-maker, and further, that any such benefits outweigh the economic costs.
