Search Results For google

Google is facing a series of lawsuits in 2020 and 2021 that challenge some of the most fundamental parts of its business, and of the internet itself — Search, Android, Chrome, Google’s digital-advertising business, and potentially other services as well. 

The U.S. Justice Department (DOJ) has brought a case alleging that Google’s deals with Android smartphone manufacturers, Apple, and third-party browsers to make Google Search their default general search engine are anticompetitive (ICLE’s tl;dr on the case is here), and the State of Texas has brought a suit against Google’s display advertising business. These follow a market study by the United K’s Competition and Markets Authority that recommended an ex ante regulator and code of conduct for Google and Facebook. At least one more suit is expected to follow.

These lawsuits will test ideas that are at the heart of modern antitrust debates: the roles of defaults and exclusivity deals in competition; the costs of self-preferencing and its benefits to competition; the role of data in improving software and advertising, and its role as a potential barrier to entry; and potential remedies in these markets and their limitations.

This Truth on the Market symposium asks contributors with wide-ranging viewpoints to comment on some of these issues as they arise in the lawsuits being brought—starting with the U.S. Justice Department’s case against Google for alleged anticompetitive practices in search distribution and search-advertising markets—and continuing throughout the duration of the lawsuits.

This Truth on the Market symposium asks contributors with wide-ranging viewpoints to comment on some of these issues as they arise in the lawsuits being brought—starting with the U.S. Justice Department’s case against Google for alleged anticompetitive practices in search distribution and search-advertising markets—and continuing throughout the duration of the lawsuits.

[TOTM: The following is part of a digital symposium by TOTM guests and authors on the law, economics, and policy of the antitrust lawsuits against Google. The entire series of posts is available here.]

On October 20, 2020, the U.S. Department of Justice (DOJ) and eleven states with Republican attorneys general sued Google for monopolizing and attempting to monopolize the markets for general internet search services, search advertising, and “general search text” advertising (i.e., ads that resemble search results).  Last week, California joined the lawsuit, making it a bipartisan affair.

DOJ and the states (collectively, “the government”) allege that Google has used contractual arrangements to expand and cement its dominance in the relevant markets.  In particular, the government complains that Google has agreed to share search ad revenues in exchange for making Google Search the default search engine on various “search access points.” 

Google has entered such agreements with Apple (for search on iPhones and iPads), manufacturers of Android devices and the mobile service carriers that support them, and producers of web browsers.  Google is also pursuing default status on new internet-enabled consumer products, such as voice assistants and “smart” TVs, appliances, and wearables.  In the government’s telling, this all amounts to Google’s sharing of monopoly profits with firms that can ensure its continued monopoly by imposing search defaults that users are unlikely to alter.

There are several obvious weaknesses with the government’s case.  One is that preset internet defaults are super easy to change and, in other contexts, are regularly altered.  For example, while 88% of desktop and laptop computers use the Windows operating system, which defaults to a Microsoft browser (Internet Explorer or Edge), Google’s Chrome browser commands a 69% market share on desktops and laptops, compared to around 13% for Internet Explorer and Edge combined.  Changing a default search engine is as easy as changing a browser default—three simple steps on an iPhone!—and it seems consumers will change defaults they don’t actually prefer.

A second obvious weakness, related to the first, is that the government has alleged no facts suggesting that Google’s search rivals—primarily Bing, Yahoo, and DuckDuckGo—would have enjoyed more success but for Google’s purportedly exclusionary agreements.  Even absent default status, people likely would have selected Google Search because it’s the better search engine.  It doesn’t seem the challenged arrangements caused Google’s search dominance.

Admittedly, the standard of causation in monopolization cases (at least those seeking only injunctive relief) is low.  The D.C. Circuit’s Microsoft decision described it as “edentulous” or, less pretentiously, toothless.  Nevertheless, the government is unlikely to prevail in its action against Google—and that’s a good thing.  Below, I highlight the central deficiency in the government’s Google case and point out problems with the government’s challenges to each of Google’s purportedly exclusionary arrangements.   

The Lawsuit’s Overarching Deficiency

We’ve all had the experience of typing a query only to have Google, within a few key strokes, accurately predict what we were going to ask and provide us with exactly the answer we were looking for.  It’s both eerie and awesome, and it keeps us returning to Google time and again.

But it’s not magic.  Nor has Google hacked our brains.  Google is so good at predicting our questions and providing responsive search results because its top-notch algorithms process gazillions of searches and can “learn” from users’ engagement.  Scale is thus essential to Google’s quality. 

The government’s complaint concedes as much.  It acknowledges that “[g]reater scale improves the quality of a general search engine’s algorithms” (¶35) and that “[t]he additional data from scale allows improved automated learning for algorithms to deliver more relevant results, particularly on ‘fresh’ queries (queries seeking recent information), location-based queries (queries asking about something in the searcher’s vicinity), and ‘long-tail’ queries (queries used infrequently)” (¶36). The complaint also asserts that “[t]he most effective way to achieve scale is for the general search engine to be the preset default on mobile devices, computers, and other devices…” (¶38).

Oddly, though, the government chides Google for pursuing “[t]he most effective way” of securing the scale that concededly “improves the quality of a general search engine’s algorithms.”  Google’s efforts to ensure and enhance its own product quality are improper, the government says, because “they deny rivals scale to compete effectively” (¶8).  In the government’s view, Google is legally obligated to forego opportunities to make its own product better so as to give its rivals a chance to improve their own offerings.

This is inconsistent with U.S. antitrust law.  Just as firms are not required to hold their prices high to create a price umbrella for their less efficient rivals, they need not refrain from efforts to improve the quality of their own offerings so as to give their rivals a foothold. 

Antitrust does forbid anticompetitive foreclosure of rivals—i.e., business-usurping arrangements that are not the result of efforts to compete on the merits by reducing cost or enhancing quality.  But firms are, and should be, free to make their products better, even if doing so makes things more difficult for their rivals.  Antitrust, after all, protects competition, not competitors.    

The central deficiency in the government’s case is that it concedes that scale is crucial to search engine quality, but it does not assert that there is a “minimum efficient scale”—i.e., a point at which scale economies are exhausted.  If a firm takes actions to enhance its own scale beyond minimum efficient scale, and if its efforts may hold its rivals below such scale, then it may have engaged in anticompetitive foreclosure.  But a firm that pursues scale that makes its products better is simply competing on the merits.

The government likely did not allege that there is a minimum efficient scale in general internet search services because returns to scale go on indefinitely, or at least for a very long time.  But the absence of such an allegation damns the government’s case against Google, for it implies that Google’s efforts to secure the distribution, and thus the greater use, of its services make those services better.

In this regard, the Microsoft case, which the government points to as a model for its action against Google (¶10), is inapposite.  Inthat case, the government alleged that Microsoft had entered license agreements that foreclosed Netscape, a potential rival, from the best avenues of browser distribution: original equipment manufacturers (OEMs) and internet access providers.  The government here similarly alleges that Google has foreclosed rival search engines from the best avenues of search distribution: default settings on mobile devices and web browsers.  But a key difference (in addition to the fact that search defaults are quite easy to change) is that Microsoft’s license restrictions foreclosed Netscape without enhancing the quality of Microsoft’s offerings.  Indeed, the court emphasized that the challenged Microsoft agreements were anticompetitive because they “reduced rival browsers’ usage share not by improving [Microsoft’s] own product but, rather, by preventing OEMs from taking actions that could increase rivals’ share of usage” (emphasis added).  Here, any foreclosure of Google’s search rivals is incidental to Google’s efforts to improve its product by enhancing its scale.

Now, the government might contend that the anticompetitive harms from raising rivals’ distribution costs exceed the procompetitive benefits of enhancing the quality of Google’s search services.  Courts, though, have generally been skeptical of claims that exclusion-causing product enhancements are anticompetitive because they do more harm than good.  There’s a sound reason for this: courts are ill-equipped to weigh the benefits of product enhancements against the costs of competition reductions resulting from product-enhancement efforts.  For that reason, they should—and likely will—stick with the rule that this sort of product-enhancing conduct is competition on the merits, even if it has the incidental effect of raising rivals’ costs.  And if they do so, the government will lose this case.     

Problems with the Government’s Specific Challenges

Agreements with Android OEMs and Wireless Carriers

The government alleges that Google has foreclosed its search rivals from distribution opportunities on the Android platform.  It has done so, the government says, by entering into exclusion-causing agreements with OEMs that produce Android products (Samsung, Motorola, etc.) and with carriers that provide wireless service for Android devices (AT&T, Verizon, etc.).

Android is an open source operating system that is owned by Google and licensed, for free, to producers of mobile internet devices.  Under the terms of the challenged agreements, Google’s counterparties promise not to produce Android “forks”—operating systems that are Android-based but significantly alter or “fragment” the basic platform—in order to get access to proprietary Google apps that Android users typically desire and to certain application protocol interfaces (APIs) that enable various functionalities.  In addition to these “anti-forking agreements,” counterparties enter various “pre-installation agreements” obligating them to install a suite of Google apps that use Google Search as a default.  Installing that suite is a condition for obtaining the right to pre-install Google’s app store (Google Play) and other must-have apps.  Finally, OEMs and carriers enter “revenue sharing agreements” that require the use of Google Search as the sole preset default on a number of search access points in exchange for a percentage of search ad revenue derived from covered devices.  Taken together, the government says, these anti-forking, pre-installation, and revenue-sharing agreements preclude the emergence of Android rivals (from forks) and ensure the continued dominance of Google Search on Android devices.

Eliminating these agreements, though, would likely harm consumers by reducing competition in the market for mobile operating systems.  Within that market, there are two dominant players: Apple’s iOS and Google’s Android.  Apple earns money off iOS by selling hardware—iPhones and iPads that are pre-installed with iOS.  Google licenses Android to OEMs for free but then earns advertising revenue off users’ searches (which provide an avenue for search ads) and other activities (which generate user data for better targeted display ads).  Apple and Google thus compete on revenue models.  As Randy Picker has explained, Microsoft tried a third revenue model—licensing a Windows mobile operating system to OEMs for a fee—but it failed.  The continued competition between Apple and Google, though, allows for satisfaction of heterogenous consumer preferences: Apple products are more expensive but more secure (due to Apple’s tight control over software and hardware); Android devices are cheaper (as the operating system is ad-supported) and offer more innovations (as OEMs have more flexibility), but tend to be less secure.  Such variety—a result of business model competition—is good for consumers. 

If the government were to prevail and force Google to end the agreements described above, thereby reducing the advertising revenue Google derives from Android, Google would have to either copy Apple’s vertically integrated model so as to recoup its Android investments through hardware sales, charge OEMs for Android (a la Microsoft), or cut back on its investments in Android.  In each case, consumers would suffer.  The first option would take away an offering preferred by many consumers—indeed most globally, as Android dominates iOS on a worldwide basis.  The second option would replace Google’s business model with one that failed, suggesting that consumers value it less.  The third option would reduce product quality in the market for mobile operating systems. 

In the end, then, the government’s challenge to Google’s Android agreements is myopic and misguided.  Competition among business models, like competition along any dimension, inures to the benefit of consumers.  Precluding it as the government is demanding would be silly.       

Agreements with Browser Producers

Web browsers like Apple’s Safari and Mozilla’s Firefox are a primary distribution channel for search engines.  The government claims that Google has illicitly foreclosed rival search engines from this avenue of distribution by entering revenue-sharing agreements with the major non-Microsoft browsers (i.e., all but Microsoft’s Edge and Internet Explorer).  Under those agreements, Google shares up to 40% of ad revenues generated from a browser in exchange for being the preset default on both computer and mobile versions of the browser.

Surely there is no problem, though, with search engines paying royalties to web browsers.  That’s how independent browsers like Opera and Firefox make money!  Indeed, 95% of Firefox’s revenue comes from search royalties.  If browsers were precluded from sharing in search engines’ ad revenues, they would have to find an alternative source of financing.  Producers of independent browsers would likely charge license fees, which consumers would probably avoid.  That means the only available browsers would be those affiliated with an operating system (Microsoft’s Edge, Apple’s Safari) or a search engine (Google’s Chrome).  It seems doubtful that reducing the number of viable browsers would benefit consumers.  The law should therefore allow payment of search royalties to browsers.  And if such payments are permitted, a browser will naturally set its default search engine so as to maximize its payout.  

Google’s search rivals can easily compete for default status on a browser by offering a better deal to the browser producer.  In 2014, for example, search engine Yahoo managed to wrest default status on Mozilla’s Firefox away from Google.  The arrangement was to last five years, but in 2017, Mozilla terminated the agreement and returned Google to default status because so many Firefox users were changing the browser’s default search engine from Yahoo to Google.  This historical example undermines the government’s challenges to Google’s browser agreements by showing (1) that other search engines can attain default status by competing, and (2) that defaults aren’t as “sticky” as the government claims—at least, not when the default is set to a search engine other than the one most people prefer.

In short, there’s nothing anticompetitive about Google’s browser agreements, and enjoining such deals would likely injure consumers by reducing competition among browsers.

Agreements with Apple

That brings us to the allegations that have gotten the most attention in the popular press: those concerning Google’s arrangements with Apple.  The complaint alleges that Google pays Apple $8-12 billion a year—a whopping 15-20% of Apple’s net income—for granting Google default search status on iOS devices.  In the government’s telling, Google is agreeing to share a significant portion of its monopoly profits with Apple in exchange for Apple’s assistance in maintaining Google’s search monopoly.

An alternative view, of course, is that Google is just responding to Apple’s power: Apple has assembled a giant installed base of loyal customers and can demand huge payments to favor one search engine over another on its popular mobile devices.  In that telling, Google may be paying Apple to prevent it from making Bing or another search engine the default on Apple’s search access points.

If that’s the case, what Google is doing is both procompetitive and a boon to consumers.  Microsoft could easily outbid Google to have Bing set as the default search engine on Apple’s devices. Microsoft’s market capitalization exceeds that of Google parent Alphabet by about $420 billion ($1.62 trillion versus $1.2 trillion), which is roughly the value of Walmart.  Despite its ability to outbid Google for default status, Microsoft hasn’t done so, perhaps because it realizes that defaults aren’t that sticky when the default service isn’t the one most people prefer.  Microsoft knows that from its experience with Internet Explorer and Edge (which collectively command only around 13% of the desktop browser market even though they’re the defaults on Windows, which has a 88% market share on desktops and laptops), and from its experience with Bing (where “Google” is the number one search term).  Nevertheless, the possibility remains that Microsoft could outbid Google for default status, improve its quality to prevent users from changing the default (or perhaps pay users for sticking with Bing), and thereby take valuable scale from Google, impairing the quality of Google Search.  To prevent that from happening, Google shares with Apple a generous portion of its search ad revenues, which, given the intense competition for mobile device sales, Apple likely passes along to consumers in the form of lower phone and tablet prices.

If the government succeeds in enjoining Google’s payments to Apple for default status, other search engines will presumably be precluded from such arrangements as well.  After all, the “foreclosure” effect of paying for default search status on Apple products is the same regardless of which search engine does the paying, and U.S. antitrust law does not “punish” successful firms by forbidding them from engaging in competitive activities that are open to their rivals. 

Ironically, then, the government’s success in its challenge to Google’s Apple payments would benefit Google at the expense of consumers:  Google would almost certainly remain the default search engine on Apple products, as it is most preferred by consumers and no rival could pay to dislodge it; Google would not have to pay a penny to retain its default status; and Apple would lose revenues that it likely passes along to consumers in the form of lower prices.  The courts are unlikely to countenance this perverse result by ruling that Google’s arrangements with Apple violate the antitrust laws.

Arrangements with Producers of Internet-Enabled “Smart” Devices

The final part of the government’s case against Google starkly highlights a problem that is endemic to the entire lawsuit.  The government claims that Google, having locked up all the traditional avenues of search distribution with the arrangements described above, is now seeking to foreclose search distribution in the new avenues being created by internet-enabled consumer products like wearables (e.g., smart watches), voice assistants, smart TVs, etc.  The alleged monopolistic strategy is similar to those described above: Google will share some of its monopoly profits in exchange for search default status on these smart devices, thereby preventing rival search engines from attaining valuable scale.

It’s easy to see in this context, though, why Google’s arrangements are likely procompetitive.  Unlike web browsers, mobile phones, and tablets, internet-enabled smart devices are novel.  Innovators are just now discovering new ways to embed internet functionality into everyday devices. 

Putting oneself in the position of these innovators helps illuminate a key beneficial aspect of Google’s arrangements:  They create an incentive to develop new and attractive means of distributing search.  Innovators currently at work on internet-enabled devices are no doubt spurred on by the possibility of landing a lucrative distribution agreement with Google or another search engine.  Banning these sorts of arrangements—the consequence of governmental success in this lawsuit—would diminish the incentive to innovate.

But that can be said of every single one of the arrangements the government is challenging. Because of Google’s revenue-sharing with search distributors, each of them has an added incentive to make their distribution channels desirable to consumers.  Android OEMs and Apple will work harder to produce mobile devices that people will want to use for internet searches; browser producers will endeavor to improve their offerings.  By paying producers of search access points a portion of the search ad revenues generated on their platforms, Google motivates them to generate more searches, which they can best do by making their products as attractive as possible. 

At the end of the day, then, the government’s action against Google seeks to condemn conduct that benefits consumers.  Because of the challenged arrangements, Google makes its own search services better, is able to license Android for free, ensures the continued existence of independent web browsers like Firefox and Opera, helps lower the price of iPhones and iPads, and spurs innovators to develop new “Internet of Things” devices that can harness the power of the web. 

The Biden administration would do well to recognize this lawsuit for what it is: a poorly conceived effort to appear to be “doing something” about a Big Tech company that has drawn the ire (for different reasons) of both progressives and conservatives.  DOJ and its state co-plaintiffs should seek dismissal of this action.

The U.S. Department of Justice’s (DOJ) antitrust case against Google, which was filed in October 2020, will be a tough slog.[1] It is an alleged monopolization (Sherman Act, Sec. 2) case; and monopolization cases are always a tough slog.

In this brief essay I will lay out some of the issues in the case and raise an intriguing possibility.

What is the case about?

The case is about exclusivity and exclusion in the distribution of search engine services; that Google paid substantial sums to Apple and to the manufacturers of Android-based mobile phones and tablets and also to wireless carriers and web-browser proprietors—in essence, to distributors—to install the Google search engine as the exclusive pre-set (installed), default search program. The suit alleges that Google thereby made it more difficult for other search-engine providers (e.g., Bing; DuckDuckGo) to obtain distribution for their search-engine services and thus to attract search-engine users and to sell the online advertising that is associated with search-engine use and that provides the revenue to support the search “platform” in this “two-sided market” context.[2]

Exclusion can be seen as a form of “raising rivals’ costs.”[3]  Equivalently, exclusion can be seen as a form of non-price predation. Under either interpretation, the exclusionary action impedes competition.

It’s important to note that these allegations are different from those that motivated an investigation by the Federal Trade Commission (which the FTC dropped in 2013) and the cases by the European Union against Google.[4]  Those cases focused on alleged self-preferencing; that Google was unduly favoring its own products and services (e.g., travel services) in its delivery of search results to users of its search engine. In those cases, the impairment of competition (arguably) happens with respect to those competing products and services, not with respect to search itself.

What is the relevant market?

For a monopolization allegation to have any meaning, there needs to be the exercise of market power (which would have adverse consequences for the buyers of the product). And in turn, that exercise of market power needs to occur in a relevant market: one in which market power can be exercised.

Here is one of the important places where the DOJ’s case is likely to turn into a slog: the delineation of a relevant market for alleged monopolization cases remains as a largely unsolved problem for antitrust economics.[5]  This is in sharp contrast to the issue of delineating relevant markets for the antitrust analysis of proposed mergers.  For this latter category, the paradigm of the “hypothetical monopolist” and the possibility that this hypothetical monopolist could prospectively impose a “small but significant non-transitory increase in price” (SSNIP) has carried the day for the purposes of market delineation.

But no such paradigm exists for monopolization cases, in which the usual allegation is that the defendant already possesses market power and has used the exclusionary actions to buttress that market power. To see the difficulties, it is useful to recall the basic monopoly diagram from Microeconomics 101. A monopolist faces a negatively sloped demand curve for its product (at higher prices, less is bought; at lower prices, more is bought) and sets a profit-maximizing price at the level of output where its marginal revenue (MR) equals its marginal costs (MC). Its price is thereby higher than an otherwise similar competitive industry’s price for that product (to the detriment of buyers) and the monopolist earns higher profits than would the competitive industry.

But unless there are reliable benchmarks as to what the competitive price and profits would otherwise be, any information as to the defendant’s price and profits has little value with respect to whether the defendant already has market power. Also, a claim that a firm does not have market power because it faces rivals and thus isn’t able profitably to raise its price from its current level (because it would lose too many sales to those rivals) similarly has no value. Recall the monopolist from Micro 101. It doesn’t set a higher price than the one where MR=MC, because it would thereby lose too many sales to other sellers of other things.

Thus, any firm—regardless of whether it truly has market power (like the Micro 101 monopolist) or is just another competitor in a sea of competitors—should have already set its price at its profit-maximizing level and should find it unprofitable to raise its price from that level.[6]  And thus the claim, “Look at all of the firms that I compete with!  I don’t have market power!” similarly has no informational value.

Let us now bring this problem back to the Google monopolization allegation:  What is the relevant market?  In the first instance, it has to be “the provision of answers to user search queries.” After all, this is the “space” in which the exclusion occurred. But there are categories of search: e.g., search for products/services, versus more general information searches (“What is the current time in Delaware?” “Who was the 21st President of the United States?”). Do those separate categories themselves constitute relevant markets?

Further, what would the exercise of market power in a (delineated relevant) market look like?  Higher-than-competitive prices for advertising that targets search-results recipients is one obvious answer (but see below). In addition, because this is a two-sided market, the competitive “price” (or prices) might involve payments by the search engine to the search users (in return for their exposure to the lucrative attached advertising).[7]  And product quality might exhibit less variety than a competitive market would provide; and/or the monopolistic average level of quality would be lower than in a competitive market: e.g., more abuse of user data, and/or deterioration of the delivered information itself, via more self-preferencing by the search engine and more advertising-driven preferencing of results.[8]

In addition, a natural focus for a relevant market is the advertising that accompanies the search results. But now we are at the heart of the difficulty of delineating a relevant market in a monopolization context. If the relevant market is “advertising on search engine results pages,” it seems highly likely that Google has market power. If the relevant market instead is all online U.S. advertising (of which Google’s revenue share accounted for 32% in 2019[9]), then the case is weaker; and if the relevant market is all advertising in the United States (which is about twice the size of online advertising[10]), the case is weaker still. Unless there is some competitive benchmark, there is no easy way to delineate the relevant market.[11]

What exactly has Google been paying for, and why?

As many critics of the DOJ’s case have pointed out, it is extremely easy for users to switch their default search engine. If internet search were a normal good or service, this ease of switching would leave little room for the exercise of market power. But in that case, why is Google willing to pay $8-$12 billion annually for the exclusive default setting on Apple devices and large sums to the manufacturers of Android-based devices (and to wireless carriers and browser proprietors)? Why doesn’t Google instead run ads in prominent places that remind users how superior Google’s search results are and how easy it is for users (if they haven’t already done so) to switch to the Google search engine and make Google the user’s default choice?

Suppose that user inertia is important. Further suppose that users generally have difficulty in making comparisons with respect to the quality of delivered search results. If this is true, then being the default search engine on Apple and Android-based devices and on other distribution vehicles would be valuable. In this context, the inertia of their customers is a valuable “asset” of the distributors that the distributors may not be able to take advantage of, but that Google can (by providing search services and selling advertising). The question of whether Google’s taking advantage of this user inertia means that Google exercises market power takes us back to the issue of delineating the relevant market.

There is a further wrinkle to all of this. It is a well-understood concept in antitrust economics that an incumbent monopolist will be willing to pay more for the exclusive use of an essential input than a challenger would pay for access to the input.[12] The basic idea is straightforward. By maintaining exclusive use of the input, the incumbent monopolist preserves its (large) monopoly profits. If the challenger enters, the incumbent will then earn only its share of the (much lower, more competitive) duopoly profits. Similarly, the challenger can expect only the lower duopoly profits. Accordingly, the incumbent should be willing to outbid (and thereby exclude) the challenger and preserve the incumbent’s exclusive use of the input, so as to protect those monopoly profits.

To bring this to the Google monopolization context, if Google does possess market power in some aspect of search—say, because online search-linked advertising is a relevant market—then Google will be willing to outbid Microsoft (which owns Bing) for the “asset” of default access to Apple’s (inertial) device owners. That Microsoft is a large and profitable company and could afford to match (or exceed) Google’s payments to Apple is irrelevant. If the duopoly profits for online search-linked advertising would be substantially lower than Google’s current profits, then Microsoft would not find it worthwhile to try to outbid Google for that default access asset.

Alternatively, this scenario could be wholly consistent with an absence of market power. If search users (who can easily switch) consider Bing to be a lower-quality search service, then large payments by Microsoft to outbid Google for those exclusive default rights would be largely wasted, since the “acquired” default search users would quickly switch to Google (unless Microsoft provided additional incentives for the users not to switch).

But this alternative scenario returns us to the original puzzle:  Why is Google making such large payments to the distributors for those exclusive default rights?

An intriguing possibility

Consider the following possibility. Suppose that Google was paying that $8-$12 billion annually to Apple in return for the understanding that Apple would not develop its own search engine for Apple’s device users.[13] This possibility was not raised in the DOJ’s complaint, nor is it raised in the subsequent suits by the state attorneys general.

But let’s explore the implications by going to an extreme. Suppose that Google and Apple had a formal agreement that—in return for the $8-$12 billion per year—Apple would not develop its own search engine. In this event, this agreement not to compete would likely be seen as a violation of Section 1 of the Sherman Act (which does not require a market delineation exercise) and Apple would join Google as a co-conspirator. The case would take on the flavor of the FTC’s prosecution of “pay-for-delay” agreements between the manufacturers of patented pharmaceuticals and the generic drug manufacturers that challenge those patents and then receive payments from the former in return for dropping the patent challenge and delaying the entry of the generic substitute.[14]

As of this writing, there is no evidence of such an agreement and it seems quite unlikely that there would have been a formal agreement. But the DOJ will be able to engage in discovery and take depositions. It will be interesting to find out what the relevant executives at Google—and at Apple—thought was being achieved by those payments.

What would be a suitable remedy/relief?

The DOJ’s complaint is vague with respect to the remedy that it seeks. This is unsurprising. The DOJ may well want to wait to see how the case develops and then amend its complaint.

However, even if Google’s actions have constituted monopolization, it is difficult to conceive of a suitable and effective remedy. One apparently straightforward remedy would be to require simply that Google not be able to purchase exclusivity with respect to the pre-set default settings. In essence, the device manufacturers and others would always be able to sell parallel default rights to other search engines: on the basis, say, that the default rights for some categories of customers—or even a percentage of general customers (randomly selected)—could be sold to other search-engine providers.

But now the Gilbert-Newbery insight comes back into play. Suppose that a device manufacturer knows (or believes) that Google will pay much more if—even in the absence of any exclusivity agreement—Google ends up being the pre-set search engine for all (or nearly all) of the manufacturer’s device sales, as compared with what the manufacturer would receive if those default rights were sold to multiple search-engine providers (including, but not solely, Google). Can that manufacturer (recall that the distributors are not defendants in the case) be prevented from making this sale to Google and thus (de facto) continuing Google’s exclusivity?[15]

Even a requirement that Google not be allowed to make any payment to the distributors for a default position may not improve the competitive environment. Google may be able to find other ways of making indirect payments to distributors in return for attaining default rights, e.g., by offering them lower rates on their online advertising.

Further, if the ultimate goal is an efficient outcome in search, it is unclear how far restrictions on Google’s bidding behavior should go. If Google were forbidden from purchasing any default installation rights for its search engine, would (inert) consumers be better off? Similarly, if a distributor were to decide independently that its customers were better served by installing the Google search engine as the default, would that not be allowed? But if it is allowed, how could one be sure that Google wasn’t indirectly paying for this “independent” decision (e.g., through favorable advertising rates)?

It’s important to remember that this (alleged) monopolization is different from the Standard Oil case of 1911 or even the (landline) AT&T case of 1984. In those cases, there were physical assets that could be separated and spun off to separate companies. For Google, physical assets aren’t important. Although it is conceivable that some of Google’s intellectual property—such as Gmail, YouTube, or Android—could be spun off to separate companies, doing so would do little to cure the (arguably) fundamental problem of the inert device users.

In addition, if there were an agreement between Google and Apple for the latter not to develop a search engine, then large fines for both parties would surely be warranted. But what next? Apple can’t be forced to develop a search engine.[16] This differentiates such an arrangement from the “pay-for-delay” arrangements for pharmaceuticals, where the generic manufacturers can readily produce a near-identical substitute for the patented drug and are otherwise eager to do so.

At the end of the day, forbidding Google from paying for exclusivity may well be worth trying as a remedy. But as the discussion above indicates, it is unlikely to be a panacea and is likely to require considerable monitoring for effective enforcement.

Conclusion

The DOJ’s case against Google will be a slog. There are unresolved issues—such as how to delineate a relevant market in a monopolization case—that will be central to the case. Even if the DOJ is successful in showing that Google violated Section 2 of the Sherman Act in monopolizing search and/or search-linked advertising, an effective remedy seems problematic. But there also remains the intriguing question of why Google was willing to pay such large sums for those exclusive default installation rights?

The developments in the case will surely be interesting.


[1] The DOJ’s suit was joined by 11 states.  More states subsequently filed two separate antitrust lawsuits against Google in December.

[2] There is also a related argument:  That Google thereby gained greater volume, which allowed it to learn more about its search users and their behavior, and which thereby allowed it to provide better answers to users (and thus a higher-quality offering to its users) and better-targeted (higher-value) advertising to its advertisers.  Conversely, Google’s search-engine rivals were deprived of that volume, with the mirror-image negative consequences for the rivals.  This is just another version of the standard “learning-by-doing” and the related “learning curve” (or “experience curve”) concepts that have been well understood in economics for decades.

[6] The forgetting of this important point is often termed “the cellophane fallacy”, since this is what the U.S. Supreme Court did in a 1956 antitrust case in which the DOJ alleged that du Pont had monopolized the cellophane market (and du Pont, in its defense claimed that the relevant market was much wider: all flexible wrapping materials); see U.S. v. du Pont, 351 U.S. 377 (1956).  For an argument that profit data and other indicia argued for cellophane as the relevant market, see George W. Stocking and Willard F. Mueller, “The Cellophane Case and the New Competition,” American Economic Review, Vol. 45, No. 1 (March 1955), pp. 29-63.

[7] In the context of differentiated services, one would expect prices (positive or negative) to vary according to the quality of the service that is offered.  It is worth noting that Bing offers “rewards” to frequent searchers; see https://www.microsoft.com/en-us/bing/defaults-rewards.  It is unclear whether this pricing structure of payment to Bing’s customers represents what a more competitive framework in search might yield, or whether the payment just indicates that search users consider Bing to be a lower-quality service.

[8] As an additional consequence of the impairment of competition in this type of search market, there might be less technological improvement in the search process itself – to the detriment of users.

[13] To my knowledge, Randal C. Picker was the first to suggest this possibility; see https://www.competitionpolicyinternational.com/a-first-look-at-u-s-v-google/.  Whether Apple would be interested in trying to develop its own search engine – given the fiasco a decade ago when Apple tried to develop its own maps app to replace the Google maps app – is an open question.  In addition, the Gilbert-Newbery insight applies here as well:  Apple would be less inclined to invest the substantial resources that would be needed to develop a search engine when it is thereby in a duopoly market.  But Google might be willing to pay “insurance” to reinforce any doubts that Apple might have.

[14] The U.S. Supreme Court, in FTC v. Actavis, 570 U.S. 136 (2013), decided that such agreements could be anti-competitive and should be judged under the “rule of reason”.  For a discussion of the case and its implications, see, for example, Joseph Farrell and Mark Chicu, “Pharmaceutical Patents and Pay-for-Delay: Actavis (2013),” in John E. Kwoka, Jr., and Lawrence J. White, eds. The Antitrust Revolution: Economics, Competition, and Policy, 7th edn.  Oxford University Press, 2019, pp. 331-353.

[15] This is an example of the insight that vertical arrangements – in this case combined with the Gilbert-Newbery effect – can be a way for dominant firms to raise rivals’ costs.  See, for example, John Asker and Heski Bar-Isaac. 2014. “Raising Retailers’ Profits: On Vertical Practices and the Exclusion of Rivals.” American Economic Review, Vol. 104, No. 2 (February 2014), pp. 672-686.

[16] And, again, for the reasons discussed above, Apple might not be eager to make the effort.

[TOTM: The following is part of a digital symposium by TOTM guests and authors on the law, economics, and policy of the antitrust lawsuits against Google. The entire series of posts is available here.]

Judges sometimes claim that they do not pick winners when they decide antitrust cases. Nothing could be further from the truth.

Competitive conduct by its nature harms competitors, and so if antitrust were merely to prohibit harm to competitors, antitrust would then destroy what it is meant to promote.

What antitrust prohibits, therefore, is not harm to competitors but rather harm to competitors that fails to improve products. Only in this way is antitrust able to distinguish between the good firm that harms competitors by making superior products that consumers love and that competitors cannot match and the bad firm that harms competitors by degrading their products without offering consumers anything better than what came before.

That means, however, that antitrust must pick winners: antitrust must decide what is an improvement and what not. And a more popular search engine is a clear winner.

But one should not take its winningness for granted. For once upon a time there was another winner that the courts always picked, blocking antitrust case after antitrust case. Until one day the courts stopped picking it.

That was the economy of scale.

The Structure of the Google Case

Like all antitrust cases that challenge the exercise of power, the government’s case against Google alleges denial of an input to competitors in some market. Here the input is default search status in smartphones, the competitors are rival search providers, and the market is search advertising. The basic structure of the case is depicted in the figure below.

Although brought as a monopolization case under Section 2 of the Sherman Act, this is at heart an exclusive dealing case of the sort normally brought under Section 1 of the Sherman Act: the government’s core argument is that Google uses contracts with smartphone makers, pursuant to which the smartphone makers promise to make Google, and not competitors, the search default, to harm competing search advertising providers and by extension competition in the search advertising market.

The government must show anticompetitive conduct, monopoly power, and consumer harm in order to prevail.

Let us assume that there is monopoly power. The company has more than 70% of the search advertising market, which is in the zone normally required to prove that element of a monopolization claim.

The problem of anticompetitive conduct is only slightly more difficult.

Anticompetitive conduct is only ever one thing in antitrust: denial of an essential input to a competitor. There is no other way to harm rivals.

(To be sure, antitrust prohibits harm to competition, not competitors, but that means only that harm to competitors necessary but insufficient for liability. The consumer harm requirement decides whether the requisite harm to competitors is also harm to competition.)

It is not entirely clear just how important default search status really is to running a successful search engine, but let us assume that it is essential, as the government suggests.

Then the question whether Google’s contracts are anticompetitive turns on how much of the default search input Google’s contracts foreclose to rival search engines. If a lot, then the rivals are badly harmed. If a little, then there may be no harm at all.

The answer here is that there is a lot of foreclosure, at least if the government’s complaint is to be believed. Through its contracts with Apple and makers of Android phones, Google has foreclosed default search status to rivals on virtually every single smartphone.

That leaves consumer harm. And here is where things get iffy.

Usage as a Product Improvement: A Very Convenient Argument

The inquiry into consumer harm evokes measurements of the difference between demand curves and price lines, or extrapolations of compensating and equivalent variation using indifference curves painstakingly pieced together based on the assumptions of revealed preference.

But while the parties may pay experts plenty to spin such yarns, and judges may pretend to listen to them, in the end, for the judges, it always comes down to one question only: did exclusive dealing improve the product?

If it did, then the judge assumes that the contracts made consumers better off and the defendant wins. And if it did not, then off with their heads.

So, does foreclosing all this default search space to competitors make Google search advertising more valuable to advertisers?

Those who leap to Google’s defense say yes, for default search status increases the number of people who use Google’s search engine. And the more people use Google’s search engine, the more Google learns about how best to answer search queries and which advertisements will most interest which searchers. And that ensures that even more people will use Google’s search engine, and that Google will do an even better job of targeting ads on its search engine.

And that in turn makes Google’s search advertising even better: able to reach more people and to target ads more effectively to them.

None of that would happen if defaults were set to other engines and users spurned Google, and so foreclosing default search space to rivals undoubtedly improves Google’s product.

This is a nice argument. Indeed, it is almost too nice, for it seems to suggest that almost anything Google might do to steer users away from competitors and to itself deserves antitrust immunity. Suppose Google were to brandish arms to induce you to run your next search on Google. That would be a crime, but, on this account, not an antitrust crime. For getting you to use Google does make Google better.

The argument that locking up users improves the product is of potential use not just to Google but to any of the many tech companies that run on advertising—Facebook being a notable example—so it potentially immunizes an entire business model from antitrust scrutiny.

It turns out that has happened before.

Economies of Scale as a Product Improvement: Once a Convenient Argument

Once upon a time, antitrust exempted another kind of business for which products improve the more people used them. The business was industrial production, and it differs from online advertising only in the irrelevant characteristic that the improvement that comes with expanding use is not in the quality of the product but in the cost per unit of producing it.

The hallmark of the industrial enterprise is high fixed costs and low marginal costs. The textile mill differs from pre-industrial piecework weaving in that once a $10 million investment in machinery has been made, the mill can churn out yard after yard of cloth for pennies. The pieceworker, by contrast, makes a relatively small up-front investment—the cost of raising up the hovel in which she labors and making her few tools—but spends the same large amount of time to produce each new yard of cloth.

Large fixed costs and low marginal costs lie at the heart of the bounty of the modern age: the more you produce, the lower the unit cost, and so the lower the price at which you can sell your product. This is a recipe for plenty.

But it also means that, so long as consumer demand in a given market is lower than the capacity of any particular plant, driving buyers to a particular seller and away from competitors always improves the product, in the sense that it enables the firm to increase volume and reduce unit cost, and therefore to sell the product at a lower price.

If the promise of the modern age is goods at low prices, then the implication is that antitrust should never punish firms for driving rivals from the market and taking over their customers. Indeed, efficiency requires that only one firm should ever produce in any given market, at least in any market for which a single plant is capable of serving all customers.

For antitrust in the late 19th and early 20th centuries, beguiled by this advantage to size, exclusive dealing, refusals to deal, even the knife in a competitor’s back: whether these ran afoul of other areas of law or not, it was all for the better because it allowed industrial enterprises to achieve economies of scale.

It is no accident that, a few notable triumphs aside, antitrust did not come into its own until the mid-1930s, 40 years after its inception, on the heels of an intellectual revolution that explained, for the first time, why it might actually be better for consumers to have more than one seller in a market.

The Monopolistic Competition Revolution

The revolution came in the form of the theory of monopolistic competition and its cousin, the theory of creative destruction, developed between the 1920s and 1940s by Edward Chamberlin, Joan Robinson and Joseph Schumpeter.

These theories suggested that consumers might care as much about product quality as they do about product cost, and indeed would be willing to abandon a low-cost product for a higher-quality, albeit more expensive, one.

From this perspective, the world of economies of scale and monopoly production was the drab world of Soviet state-owned enterprises churning out one type of shoe, one brand of cleaning detergent, and so on.

The world of capitalism and technological advance, by contrast, was one in which numerous firms produced batches of differentiated products in amounts sometimes too small fully to realize all scale economies, but for which consumers were nevertheless willing to pay because the products better fit their preferences.

What is more, the striving of monopolistically competitive firms to lure away each other’s customers with products that better fit their tastes led to disruptive innovation— “creative destruction” was Schumpeter’s famous term for it—that brought about not just different flavors of the same basic concept but entirely new concepts. The competition to create a better flip phone, for example, would lead inevitably to a whole new paradigm, the smartphone.

This reasoning combined with work in the 1940s and 1950s on economic growth that quantified for the first time the key role played by technological change in the vigor of capitalist economies—the famous Solow residual—to suggest that product improvements, and not the cost reductions that come from capital accumulation and their associated economies of scale, create the lion’s share of consumer welfare. Innovation, not scale, was king.

Antitrust responded by, for the first time in its history, deciding between kinds of product improvements, rather than just in favor of improvements, casting economies of scale out of the category of improvements subject to antitrust immunity, while keeping quality improvements immune.

Casting economies of scale out of the protected product improvement category gave antitrust something to do for the first time. It meant that big firms had to plead more than just the cost advantages of being big in order to obtain license to push their rivals around. And government could now start reliably to win cases, rather than just the odd cause célèbre.

It is this intellectual watershed, and not Thurman Arnold’s tenacity, that was responsible for antitrust’s emergence as a force after World War Two.

Usage-Based Improvements Are Not Like Economies of Scale

The improvements in advertising that come from user growth fall squarely on the quality side of the ledger—the value they create is not due to the ability to average production costs over more ad buyers—and so they count as the kind of product improvements that antitrust continues to immunize today.

But given the pervasiveness of this mode of product improvement in the tech economy—the fact that virtually any tech firm that sells advertising can claim to be improving a product by driving users to itself and away from competitors—it is worth asking whether we have not reached a new stage in economic development in which this form of product improvement ought, like economies of scale, to be denied protection.

Shouldn’t the courts demand more and better innovation of big tech firms than just the same old big-data-driven improvements they serve up year after year?

Galling as it may be to those who, like myself, would like to see more vigorous antitrust enforcement in general, the answer would seem to be “no.” For what induced the courts to abandon antitrust immunity for economies of scale in the mid-20th century was not the mere fact that immunizing economies of scale paralyzed antitrust. Smashing big firms is not, after all, an end in itself.

Instead, monopolistic competition, creative destruction and the Solow residual induced the change, because they suggested both that other kinds of product improvement are more important than economies of scale and, crucially, that protecting economies of scale impedes development of those other kinds of improvements.

A big firm that excludes competitors in order to reach scale economies not only excludes competitors who might have produced an identical or near-identical product, but also excludes competitors who might have produced a better-quality product, one that consumers would have preferred to purchase even at a higher price.

To cast usage-based improvements out of the product improvement fold, a case must be made that excluding competitors in order to pursue such improvements will block a different kind of product improvement that contributes even more to consumer welfare.

If we could say, for example, that suppressing search competitors suppresses more-innovative search engines that ad buyers would prefer, even if those innovative search engines were to lack the advantages that come from having a large user base, then a case might be made that user growth should no longer count as a product improvement immune from antitrust scrutiny.

And even then, the case against usage-based improvements would need to be general enough to justify an epochal change in policy, rather than be limited to a particular technology in a particular lawsuit. For the courts hate to balance in individual cases, statements to the contrary in their published opinions notwithstanding.

But there is nothing in the Google complaint, much less the literature, to suggest that usage-based improvements are problematic in this way. Indeed, much of the value created by the information revolution seems to inhere precisely in its ability to centralize usage.

Americans Keep Voting to Centralize the Internet

In the early days of the internet, theorists mistook its decentralized architecture for a feature, rather than a bug. But internet users have since shown, time and again, that they believe the opposite.

For example, the basic protocols governing email were engineered to allow every American to run his own personal email server.

But Americans hated the freedom that created—not least the spam—and opted instead to get their email from a single server: the one run by Google as Gmail.

The basic protocols governing web traffic were also designed to allow every American to run whatever other communications services he wished—chat, video chat, RSS, webpages—on his own private server in distributed fashion.

But Americans hated the freedom that created—not least having to build and rebuild friend networks across platforms–—and they voted instead overwhelmingly to get their social media from a single server: Facebook.

Indeed, the basic protocols governing internet traffic were designed to allow every business to store and share its own data from its own computers, in whatever form.

But American businesses hated that freedom—not least the cost of having to buy and service their own data storage machines—and instead 40% of the internet is now stored and served from Amazon Web Services.

Similarly, advertisers have the option of placing advertisements on the myriad independently-run websites that make up the internet—known in the business as the “open web”—by placing orders through competitive ad exchanges. But advertisers have instead voted mostly to place ads on the handful of highly centralized platforms known as “walled gardens,” including Facebook, Google’s YouTube and, of course, Google Search.

The communications revolution, they say, is all about “bringing people together.” It turns out that’s true.

And that Google should win on consumer harm.

Remember the Telephone

Indeed, the same mid-20th century antitrust that thought so little of economies of scale as a defense immunized usage-based improvements when it encountered them in that most important of internet precursors: the telephone.

The telephone, like most internet services, gets better as usage increases. The more people are on a particular telephone network, the more valuable the network becomes to subscribers.

Just as with today’s internet services, the advantage of a large user base drove centralization of telephone services a century ago into the hands of a single firm: AT&T. Aside from a few business executives who liked the look of a desk full of handsets, consumers wanted one phone line that they could use to call everyone.

Although the government came close to breaking AT&T up in the early 20th century, the government eventually backed off, because a phone system in which you must subscribe to the right carrier to reach a friend just doesn’t make sense.

Instead, Congress and state legislatures stepped in to take the edge off monopoly by regulating phone pricing. And when antitrust finally did break AT&T up in 1982, it did so in a distinctly regulatory fashion, requiring that AT&T’s parts connect each other’s phone calls, something that Congress reinforced in the Telecommunications Act of 1996.

The message was clear: the sort of usage-based improvements one finds in communications are real product improvements. And antitrust can only intervene if it has a way to preserve them.

The equivalent of interconnection in search, that the benefits of usage, in the form of data and attention, be shared among competing search providers, might be feasible. But it is hard to imagine the court in the Google case ordering interconnection without the benefit of decades of regulatory experience with the defendant’s operations that the district court in 1982 could draw upon in the AT&T case.

The solution for the tech giants today is the same as the solution for AT&T a century ago: to regulate rather than to antitrust.

Microsoft Not to the Contrary, Because Users Were in Common

Parallels to the government’s 1990s-era antitrust case against Microsoft are not to the contrary.

As Sam Weinstein has pointed out to me, Microsoft, like Google, was at heart an exclusive dealing case: Microsoft contracted with computer manufacturers to prevent Netscape Navigator, an early web browser, from serving as the default web browser on Windows PCs.

That prevented Netscape, the argument went, from growing to compete with Windows in the operating system market, much the way the Google’s Chrome browser has become a substitute for Windows on low-end notebook computers today.

The D.C. Circuit agreed that default status was an essential input for Netscape as it sought eventually to compete with Windows in the operating system market.

The court also accepted the argument that the exclusive dealing did not improve Microsoft’s operating system product.

This at first seems to contradict the notion that usage improves products, for, like search advertising, operating systems get better as their user bases increase. The more people use an operating system, the more application developers are willing to write for the system, and the better the system therefore becomes.

It seems to follow that keeping competitors off competing operating systems and on Windows made Windows better. If the court nevertheless held Microsoft liable, it must be because the court refused to extend antitrust immunity to usage-based improvements.

The trouble with this line of argument is that it ignores the peculiar thing about the Microsoft case: that while the government alleged that Netscape was a potential competitor of Windows, Netscape was also an application that ran on Windows.

That means that, unlike Google and rival search engines, Windows and Netscape shared users.

So, Microsoft’s exclusive dealing did not increase its user base and therefore could not have improved Windows, at least not by making Windows more appealing for applications developers. Driving Netscape from Windows did not enable developers to reach even one more user. Conversely, allowing Netscape to be the default browser on Windows would not have reduced the number of Windows users, because Netscape ran on Windows.

By contrast, a user who runs a search in Bing does not run the same search simultaneously in Google, and so Bing users are not Google users. Google’s exclusive dealing therefore increases its user base and improves Google’s product, whereas Microsoft’s exclusive dealing served only to reduce Netscape’s user base and degrade Netscape’s product.

Indeed, if letting Netscape be the default browser on Windows was a threat to Windows, it was not because it prevented Microsoft from improving its product, but because Netscape might eventually have become an operating system, and indeed a better operating system, than Windows, and consumers and developers, who could be on both at the same time if they wished, might have nevertheless chosen eventually to go with Netscape alone.

Though it does not help the government in the Google case, Microsoft still does offer a beacon of hope for those concerned about size, for Microsoft’s subsequent history reminds us that yesterday’s behemoth is often today’s also ran.

And the favorable settlement terms Microsoft ultimately used to escape real consequences for its conduct 20 years ago imply that, at least in high-tech markets, we don’t always need antitrust for that to be true.

Politico has released a cache of confidential Federal Trade Commission (FTC) documents in connection with a series of articles on the commission’s antitrust probe into Google Search a decade ago. The headline of the first piece in the series argues the FTC “fumbled the future” by failing to follow through on staff recommendations to pursue antitrust intervention against the company. 

But while the leaked documents shed interesting light on the inner workings of the FTC, they do very little to substantiate the case that the FTC dropped the ball when the commissioners voted unanimously not to bring an action against Google.

Drawn primarily from memos by the FTC’s lawyers, the Politico report purports to uncover key revelations that undermine the FTC’s decision not to sue Google. None of the revelations, however, provide evidence that Google’s behavior actually harmed consumers.

The report’s overriding claim—and the one most consistently forwarded by antitrust activists on Twitter—is that FTC commissioners wrongly sided with the agency’s economists (who cautioned against intervention) rather than its lawyers (who tenuously recommended very limited intervention). 

Indeed, the overarching narrative is that the lawyers knew what was coming and the economists took wildly inaccurate positions that turned out to be completely off the mark:

But the FTC’s economists successfully argued against suing the company, and the agency’s staff experts made a series of predictions that would fail to match where the online world was headed:

— They saw only “limited potential for growth” in ads that track users across the web — now the backbone of Google parent company Alphabet’s $182.5 billion in annual revenue.

— They expected consumers to continue relying mainly on computers to search for information. Today, about 62 percent of those queries take place on mobile phones and tablets, nearly all of which use Google’s search engine as the default.

— They thought rivals like Microsoft, Mozilla or Amazon would offer viable competition to Google in the market for the software that runs smartphones. Instead, nearly all U.S. smartphones run on Google’s Android and Apple’s iOS.

— They underestimated Google’s market share, a heft that gave it power over advertisers as well as companies like Yelp and Tripadvisor that rely on search results for traffic.

The report thus asserts that:

The agency ultimately voted against taking action, saying changes Google made to its search algorithm gave consumers better results and therefore didn’t unfairly harm competitors.

That conclusion underplays what the FTC’s staff found during the probe. In 312 pages of documents, the vast majority never publicly released, staffers outlined evidence that Google had taken numerous steps to ensure it would continue to dominate the market — including emerging arenas such as mobile search and targeted advertising. [EMPHASIS ADDED]

What really emerges from the leaked memos, however, is analysis by both the FTC’s lawyers and economists infused with a healthy dose of humility. There were strong political incentives to bring a case. As one of us noted upon the FTC’s closing of the investigation: “It’s hard to imagine an agency under more pressure, from more quarters (including the Hill), to bring a case around search.” Yet FTC staff and commissioners resisted that pressure, because prediction is hard. 

Ironically, the very prediction errors that the agency’s staff cautioned against are now being held against them. Yet the claims that these errors (especially the economists’) systematically cut in one direction (i.e., against enforcement) and that all of their predictions were wrong are both wide of the mark. 

Decisions Under Uncertainty

In seeking to make an example out of the FTC economists’ inaccurate predictions, critics ignore that antitrust investigations in dynamic markets always involve a tremendous amount of uncertainty; false predictions are the norm. Accordingly, the key challenge for policymakers is not so much to predict correctly, but to minimize the impact of incorrect predictions.

Seen in this light, the FTC economists’ memo is far from the laissez-faire manifesto that critics make it out to be. Instead, it shows agency officials wrestling with uncertain market outcomes, and choosing a course of action under the assumption the predictions they make might indeed be wrong. 

Consider the following passage from FTC economist Ken Heyer’s memo:

The great American philosopher Yogi Berra once famously remarked “Predicting is difficult, especially about the future.” How right he was. And yet predicting, and making decisions based on those predictions, is what we are charged with doing. Ignoring the potential problem is not an option. So I will be reasonably clear about my own tentative conclusions and recommendation, recognizing that reasonable people, perhaps applying a somewhat different standard, may disagree. My recommendation derives from my read of the available evidence, combined with the standard I personally find appropriate to apply to Commission intervention. [EMPHASIS ADDED]

In other words, contrary to what many critics have claimed, it simply is not the case that the FTC’s economists based their recommendations on bullish predictions about the future that ultimately failed to transpire. Instead, they merely recognized that, in a dynamic and unpredictable environment, antitrust intervention requires both a clear-cut theory of anticompetitive harm and a reasonable probability that remedies can improve consumer welfare. According to the economists, those conditions were absent with respect to Google Search.

Perhaps more importantly, it is worth asking why the economists’ erroneous predictions matter at all. Do critics believe that developments the economists missed warrant a different normative stance today?

In that respect, it is worth noting that the economists’ skepticism appeared to have rested first and foremost on the speculative nature of the harms alleged and the difficulty associated with designing appropriate remedies. And yet, if anything, these two concerns appear even more salient today. 

Indeed, the remedies imposed against Google in the EU have not delivered the outcomes that enforcers expected (here and here). This could either be because the remedies were insufficient or because Google’s market position was not due to anticompetitive conduct. Similarly, there is still no convincing economic theory or empirical research to support the notion that exclusive pre-installation and self-preferencing by incumbents harm consumers, and a great deal of reason to think they benefit them (see, e.g., our discussions of the issue here and here). 

Against this backdrop, criticism of the FTC economists appears to be driven more by a prior assumption that intervention is necessary—and that it was and is disingenuous to think otherwise—than evidence that erroneous predictions materially affected the outcome of the proceedings.

To take one example, the fact that ad tracking grew faster than the FTC economists believed it would is no less consistent with vigorous competition—and Google providing a superior product—than with anticompetitive conduct on Google’s part. The same applies to the growth of mobile operating systems. Ditto the fact that no rival has managed to dislodge Google in its most important markets. 

In short, not only were the economist memos informed by the very prediction difficulties that critics are now pointing to, but critics have not shown that any of the staff’s (inevitably) faulty predictions warranted a different normative outcome.

Putting Erroneous Predictions in Context

So what were these faulty predictions, and how important were they? Politico asserts that “the FTC’s economists successfully argued against suing the company, and the agency’s staff experts made a series of predictions that would fail to match where the online world was headed,” tying this to the FTC’s failure to intervene against Google over “tactics that European regulators and the U.S. Justice Department would later label antitrust violations.” The clear message is that the current actions are presumptively valid, and that the FTC’s economists thwarted earlier intervention based on faulty analysis.

But it is far from clear that these faulty predictions would have justified taking a tougher stance against Google. One key question for antitrust authorities is whether they can be reasonably certain that more efficient competitors will be unable to dislodge an incumbent. This assessment is necessarily forward-looking. Framed this way, greater market uncertainty (for instance, because policymakers are dealing with dynamic markets) usually cuts against antitrust intervention.

This does not entirely absolve the FTC economists who made the faulty predictions. But it does suggest the right question is not whether the economists made mistakes, but whether virtually everyone did so. The latter would be evidence of uncertainty, and thus weigh against antitrust intervention.

In that respect, it is worth noting that the staff who recommended that the FTC intervene also misjudged the future of digital markets.For example, while Politico surmises that the FTC “underestimated Google’s market share, a heft that gave it power over advertisers as well as companies like Yelp and Tripadvisor that rely on search results for traffic,” there is a case to be made that the FTC overestimated this power. If anything, Google’s continued growth has opened new niches in the online advertising space.

Pinterest provides a fitting example; despite relying heavily on Google for traffic, its ad-funded service has witnessed significant growth. The same is true of other vertical search engines like Airbnb, Booking.com, and Zillow. While we cannot know the counterfactual, the vertical search industry has certainly not been decimated by Google’s “monopoly”; quite the opposite. Unsurprisingly, this has coincided with a significant decrease in the cost of online advertising, and the growth of online advertising relative to other forms.

Politico asserts not only that the economists’ market share and market power calculations were wrong, but that the lawyers knew better:

The economists, relying on data from the market analytics firm Comscore, found that Google had only limited impact. They estimated that between 10 and 20 percent of traffic to those types of sites generally came from the search engine.

FTC attorneys, though, used numbers provided by Yelp and found that 92 percent of users visited local review sites from Google. For shopping sites like eBay and TheFind, the referral rate from Google was between 67 and 73 percent.

This compares apples and oranges, or maybe oranges and grapefruit. The economists’ data, from Comscore, applied to vertical search overall. They explicitly noted that shares for particular sites could be much higher or lower: for comparison shopping, for example, “ranging from 56% to less than 10%.” This, of course, highlights a problem with the data provided by Yelp, et al.: it concerns only the websites of companies complaining about Google, not the overall flow of traffic for vertical search.

But the more important point is that none of the data discussed in the memos represents the overall flow of traffic for vertical search. Take Yelp, for example. According to the lawyers’ memo, 92 percent of Yelp searches were referred from Google. Only, that’s not true. We know it’s not true because, as Yelp CEO Jerry Stoppelman pointed out around this time in Yelp’s 2012 Q2 earnings call: 

When you consider that 40% of our searches come from mobile apps, there is quite a bit of un-monetized mobile traffic that we expect to unlock in the near future.

The numbers being analyzed by the FTC staff were apparently limited to referrals to Yelp’s website from browsers. But is there any reason to think that is the relevant market, or the relevant measure of customer access? Certainly there is nothing in the staff memos to suggest they considered the full scope of the market very carefully here. Indeed, the footnote in the lawyers’ memo presenting the traffic data is offered in support of this claim:

Vertical websites, such as comparison shopping and local websites, are heavily dependent on Google’s web search results to reach users. Thus, Google is in the unique position of being able to “make or break any web-based business.”

It’s plausible that vertical search traffic is “heavily dependent” on Google Search, but the numbers offered in support of that simply ignore the (then) 40 percent of traffic that Yelp acquired through its own mobile app, with no Google involvement at all. In any case, it is also notable that, while there are still somewhat fewer app users than web users (although the number has consistently increased), Yelp’s app users view significantly more pages than its website users do — 10 times as many in 2015, for example.

Also noteworthy is that, for whatever speculative harm Google might be able to visit on the company, at the time of the FTC’s analysis Yelp’s local ad revenue was consistently increasing — by 89% in Q3 2012. And that was without any ad revenue coming from its app (display ads arrived on Yelp’s mobile app in Q1 2013, a few months after the staff memos were written and just after the FTC closed its Google Search investigation). 

In short, the search-engine industry is extremely dynamic and unpredictable. Contrary to what many have surmised from the FTC staff memo leaks, this cuts against antitrust intervention, not in favor of it.

The FTC Lawyers’ Weak Case for Prosecuting Google

At the same time, although not discussed by Politico, the lawyers’ memo also contains errors, suggesting that arguments for intervention were also (inevitably) subject to erroneous prediction.

Among other things, the FTC attorneys’ memo argued the large upfront investments were required to develop cutting-edge algorithms, and that these effectively shielded Google from competition. The memo cites the following as a barrier to entry:

A search engine requires algorithmic technology that enables it to search the Internet, retrieve and organize information, index billions of regularly changing web pages, and return relevant results instantaneously that satisfy the consumer’s inquiry. Developing such algorithms requires highly specialized personnel with high levels of training and knowledge in engineering, economics, mathematics, sciences, and statistical analysis.

If there are barriers to entry in the search-engine industry, algorithms do not seem to be the source. While their market shares may be smaller than Google’s, rival search engines like DuckDuckGo and Bing have been able to enter and gain traction; it is difficult to say that algorithmic technology has proven a barrier to entry. It may be hard to do well, but it certainly has not proved an impediment to new firms entering and developing workable and successful products. Indeed, some extremely successful companies have entered into similar advertising markets on the backs of complex algorithms, notably Instagram, Snapchat, and TikTok. All of these compete with Google for advertising dollars.

The FTC’s legal staff also failed to see that Google would face serious competition in the rapidly growing voice assistant market. In other words, even its search-engine “moat” is far less impregnable than it might at first appear.

Moreover, as Ben Thompson argues in his Stratechery newsletter: 

The Staff memo is completely wrong too, at least in terms of the potential for their proposed remedies to lead to any real change in today’s market. This gets back to why the fundamental premise of the Politico article, along with much of the antitrust chatter in Washington, misses the point: Google is dominant because consumers like it.

This difficulty was deftly highlighted by Heyer’s memo:

If the perceived problems here can be solved only through a draconian remedy of this sort, or perhaps through a remedy that eliminates Google’s legitimately obtained market power (and thus its ability to “do evil”), I believe the remedy would be disproportionate to the violation and that its costs would likely exceed its benefits. Conversely, if a remedy well short of this seems likely to prove ineffective, a remedy would be undesirable for that reason. In brief, I do not see a feasible remedy for the vertical conduct that would be both appropriate and effective, and which would not also be very costly to implement and to police. [EMPHASIS ADDED]

Of course, we now know that this turned out to be a huge issue with the EU’s competition cases against Google. The remedies in both the EU’s Google Shopping and Android decisions were severely criticized by rival firms and consumer-defense organizations (here and here), but were ultimately upheld, in part because even the European Commission likely saw more forceful alternatives as disproportionate.

And in the few places where the legal staff concluded that Google’s conduct may have caused harm, there is good reason to think that their analysis was flawed.

Google’s ‘revenue-sharing’ agreements

It should be noted that neither the lawyers nor the economists at the FTC were particularly bullish on bringing suit against Google. In most areas of the investigation, neither recommended that the commission pursue a case. But one of the most interesting revelations from the recent leaks is that FTC lawyers did advise the commission’s leadership to sue Google over revenue-sharing agreements that called for it to pay Apple and other carriers and manufacturers to pre-install its search bar on mobile devices:

FTC staff urged the agency’s five commissioners to sue Google for signing exclusive contracts with Apple and the major wireless carriers that made sure the company’s search engine came pre-installed on smartphones.

The lawyers’ stance is surprising, and, despite actions subsequently brought by the EU and DOJ on similar claims, a difficult one to countenance. 

To a first approximation, this behavior is precisely what antitrust law seeks to promote: we want companies to compete aggressively to attract consumers. This conclusion is in no way altered when competition is “for the market” (in this case, firms bidding for exclusive placement of their search engines) rather than “in the market” (i.e., equally placed search engines competing for eyeballs).

Competition for exclusive placement has several important benefits. For a start, revenue-sharing agreements effectively subsidize consumers’ mobile device purchases. As Brian Albrecht aptly puts it:

This payment from Google means that Apple can lower its price to better compete for consumers. This is standard; some of the payment from Google to Apple will be passed through to consumers in the form of lower prices.

This finding is not new. For instance, Ronald Coase famously argued that the Federal Communications Commission (FCC) was wrong to ban the broadcasting industry’s equivalent of revenue-sharing agreements, so-called payola:

[I]f the playing of a record by a radio station increases the sales of that record, it is both natural and desirable that there should be a charge for this. If this is not done by the station and payola is not allowed, it is inevitable that more resources will be employed in the production and distribution of records, without any gain to consumers, with the result that the real income of the community will tend to decline. In addition, the prohibition of payola may result in worse record programs, will tend to lessen competition, and will involve additional expenditures for regulation. The gain which the ban is thought to bring is to make the purchasing decisions of record buyers more efficient by eliminating “deception.” It seems improbable to me that this problematical gain will offset the undoubted losses which flow from the ban on Payola.

Applying this logic to Google Search, it is clear that a ban on revenue-sharing agreements would merely lead both Google and its competitors to attract consumers via alternative means. For Google, this might involve “complete” vertical integration into the mobile phone market, rather than the open-licensing model that underpins the Android ecosystem. Valuable specialization may be lost in the process.

Moreover, from Apple’s standpoint, Google’s revenue-sharing agreements are profitable only to the extent that consumers actually like Google’s products. If it turns out they don’t, Google’s payments to Apple may be outweighed by lower iPhone sales. It is thus unlikely that these agreements significantly undermined users’ experience. To the contrary, Apple’s testimony before the European Commission suggests that “exclusive” placement of Google’s search engine was mostly driven by consumer preferences (as the FTC economists’ memo points out):

Apple would not offer simultaneous installation of competing search or mapping applications. Apple’s focus is offering its customers the best products out of the box while allowing them to make choices after purchase. In many countries, Google offers the best product or service … Apple believes that offering additional search boxes on its web browsing software would confuse users and detract from Safari’s aesthetic. Too many choices lead to consumer confusion and greatly affect the ‘out of the box’ experience of Apple products.

Similarly, Kevin Murphy and Benjamin Klein have shown that exclusive contracts intensify competition for distribution. In other words, absent theories of platform envelopment that are arguably inapplicable here, competition for exclusive placement would lead competing search engines to up their bids, ultimately lowering the price of mobile devices for consumers.

Indeed, this revenue-sharing model was likely essential to spur the development of Android in the first place. Without this prominent placement of Google Search on Android devices (notably thanks to revenue-sharing agreements with original equipment manufacturers), Google would likely have been unable to monetize the investment it made in the open source—and thus freely distributed—Android operating system. 

In short, Politico and the FTC legal staff do little to show that Google’s revenue-sharing payments excluded rivals that were, in fact, as efficient. In other words, Bing and Yahoo’s failure to gain traction may simply be the result of inferior products and cost structures. Critics thus fail to show that Google’s behavior harmed consumers, which is the touchstone of antitrust enforcement.

Self-preferencing

Another finding critics claim as important is that FTC leadership declined to bring suit against Google for preferencing its own vertical search services (this information had already been partially leaked by the Wall Street Journal in 2015). Politico’s framing implies this was a mistake:

When Google adopted one algorithm change in 2011, rival sites saw significant drops in traffic. Amazon told the FTC that it saw a 35 percent drop in traffic from the comparison-shopping sites that used to send it customers

The focus on this claim is somewhat surprising. Even the leaked FTC legal staff memo found this theory of harm had little chance of standing up in court:

Staff has investigated whether Google has unlawfully preferenced its own content over that of rivals, while simultaneously demoting rival websites…. 

…Although it is a close call, we do not recommend that the Commission proceed on this cause of action because the case law is not favorable to our theory, which is premised on anticompetitive product design, and in any event, Google’s efficiency justifications are strong. Most importantly, Google can legitimately claim that at least part of the conduct at issue improves its product and benefits users. [EMPHASIS ADDED]

More importantly, as one of us has argued elsewhere, the underlying problem lies not with Google, but with a standard asset-specificity trap:

A content provider that makes itself dependent upon another company for distribution (or vice versa, of course) takes a significant risk. Although it may benefit from greater access to users, it places itself at the mercy of the other — or at least faces great difficulty (and great cost) adapting to unanticipated, crucial changes in distribution over which it has no control…. 

…It was entirely predictable, and should have been expected, that Google’s algorithm would evolve. It was also entirely predictable that it would evolve in ways that could diminish or even tank Foundem’s traffic. As one online marketing/SEO expert puts it: On average, Google makes about 500 algorithm changes per year. 500!….

…In the absence of an explicit agreement, should Google be required to make decisions that protect a dependent company’s “asset-specific” investments, thus encouraging others to take the same, excessive risk? 

Even if consumers happily visited rival websites when they were higher-ranked and traffic subsequently plummeted when Google updated its algorithm, that drop in traffic does not amount to evidence of misconduct. To hold otherwise would be to grant these rivals a virtual entitlement to the state of affairs that exists at any given point in time. 

Indeed, there is good reason to believe Google’s decision to favor its own content over that of other sites is procompetitive. Beyond determining and ensuring relevance, Google surely has the prerogative to compete vigorously and decide how to design its products to keep up with a changing market. In this case, that means designing, developing, and offering its own content in ways that partially displace the original “ten blue links” design of its search results page and instead offer its own answers to users’ queries.

Competitor Harm Is Not an Indicator of the Need for Intervention

Some of the other information revealed by the leak is even more tangential, such as that the FTC ignored complaints from Google’s rivals:

Amazon and Facebook privately complained to the FTC about Google’s conduct, saying their business suffered because of the company’s search bias, scraping of content from rival sites and restrictions on advertisers’ use of competing search engines. 

Amazon said it was so concerned about the prospect of Google monopolizing the search advertising business that it willingly sacrificed revenue by making ad deals aimed at keeping Microsoft’s Bing and Yahoo’s search engine afloat.

But complaints from rivals are at least as likely to stem from vigorous competition as from anticompetitive exclusion. This goes to a core principle of antitrust enforcement: antitrust law seeks to protect competition and consumer welfare, not rivals. Competition will always lead to winners and losers. Antitrust law protects this process and (at least theoretically) ensures that rivals cannot manipulate enforcers to safeguard their economic rents. 

This explains why Frank Easterbrook—in his seminal work on “The Limits of Antitrust”—argued that enforcers should be highly suspicious of complaints lodged by rivals:

Antitrust litigation is attractive as a method of raising rivals’ costs because of the asymmetrical structure of incentives…. 

…One line worth drawing is between suits by rivals and suits by consumers. Business rivals have an interest in higher prices, while consumers seek lower prices. Business rivals seek to raise the costs of production, while consumers have the opposite interest…. 

…They [antitrust enforcers] therefore should treat suits by horizontal competitors with the utmost suspicion. They should dismiss outright some categories of litigation between rivals and subject all such suits to additional scrutiny.

Google’s competitors spent millions pressuring the FTC to bring a case against the company. But why should it be a failing for the FTC to resist such pressure? Indeed, as then-commissioner Tom Rosch admonished in an interview following the closing of the case:

They [Google’s competitors] can darn well bring [a case] as a private antitrust action if they think their ox is being gored instead of free-riding on the government to achieve the same result.

Not that they would likely win such a case. Google’s introduction of specialized shopping results (via the Google Shopping box) likely enabled several retailers to bypass the Amazon platform, thus increasing competition in the retail industry. Although this may have temporarily reduced Amazon’s traffic and revenue (Amazon’s sales have grown dramatically since then), it is exactly the outcome that antitrust laws are designed to protect.

Conclusion

When all is said and done, Politico’s revelations provide a rarely glimpsed look into the complex dynamics within the FTC, which many wrongly imagine to be a monolithic agency. Put simply, the FTC’s commissioners, lawyers, and economists often disagree vehemently about the appropriate course of conduct. This is a good thing. As in many other walks of life, having a market for ideas is a sure way to foster sound decision making.

But in the final analysis, what the revelations do not show is that the FTC’s market for ideas failed consumers a decade ago when it declined to bring an antitrust suit against Google. They thus do little to cement the case for antitrust intervention—whether a decade ago, or today.

This is the third in a series of TOTM blog posts discussing the Commission’s recently published Google Android decision (the first post can be found here, and the second here). It draws on research from a soon-to-be published ICLE white paper.

(Comparison of Google and Apple’s smartphone business models. Red $ symbols represent money invested; Green $ symbols represent sources of revenue; Black lines show the extent of Google and Apple’s control over their respective platforms)

For the third in my series of posts about the Google Android decision, I will delve into the theories of harm identified by the Commission. 

The big picture is that the Commission’s analysis was particularly one-sided. The Commission failed to adequately account for the complex business challenges that Google faced – such as monetizing the Android platform and shielding it from fragmentation. To make matters worse, its decision rests on dubious factual conclusions and extrapolations. The result is a highly unbalanced assessment that could ultimately hamstring Google and prevent it from effectively competing with its smartphone rivals, Apple in particular.

1. Tying without foreclosure

The first theory of harm identified by the Commission concerned the tying of Google’s Search app with the Google Play app, and of Google’s Chrome app with both the Google Play and Google Search apps.

Oversimplifying, Google required its OEMs to choose between either pre-installing a bundle of Google applications, or forgoing some of the most important ones (notably Google Play). The Commission argued that this gave Google a competitive advantage that rivals could not emulate (even though Google’s terms did not preclude OEMs from simultaneously pre-installing rival web browsers and search apps). 

To support this conclusion, the Commission notably asserted that no alternative distribution channel would enable rivals to offset the competitive advantage that Google obtained from tying. This finding is, at best, dubious. 

For a start, the Commission claimed that user downloads were not a viable alternative distribution channel, even though roughly 250 million apps are downloaded on Google’s Play store every day.

The Commission sought to overcome this inconvenient statistic by arguing that Android users were unlikely to download apps that duplicated the functionalities of a pre-installed app – why download a new browser if there is already one on the user’s phone?

But this reasoning is far from watertight. For instance, the 17th most-downloaded Android app, the “Super-Bright Led Flashlight” (with more than 587million downloads), mostly replicates a feature that is pre-installed on all Android devices. Moreover, the five most downloaded Android apps (Facebook, Facebook Messenger, Whatsapp, Instagram and Skype) provide functionalities that are, to some extent at least, offered by apps that have, at some point or another, been preinstalled on many Android devices (notably Google Hangouts, Google Photos and Google+).

The Commission countered that communications apps were not appropriate counterexamples, because they benefit from network effects. But this overlooks the fact that the most successful communications and social media apps benefited from very limited network effects when they were launched, and that they succeeded despite the presence of competing pre-installed apps. Direct user downloads are thus a far more powerful vector of competition than the Commission cared to admit.

Similarly concerning is the Commission’s contention that paying OEMs or Mobile Network Operators (“MNOs”) to pre-install their search apps was not a viable alternative for Google’s rivals. Some of the reasons cited by the Commission to support this finding are particularly troubling.

For instance, the Commission claimed that high transaction costs prevented parties from concluding these pre installation deals. 

But pre-installation agreements are common in the smartphone industry. In recent years, Microsoft struck a deal with Samsung to pre-install some of its office apps on the Galaxy Note 10. It also paid Verizon to pre-install the Bing search app on a number of Samsung phones, in 2010. Likewise, a number of Russian internet companies have been in talks with Huawei to pre-install their apps on its devices. And Yahoo reached an agreement with Mozilla to make it the default search engine for its web browser. Transaction costs do not appear to  have been an obstacle in any of these cases.

The Commission also claimed that duplicating too many apps would cause storage space issues on devices. 

And yet, a back-of-the-envelope calculation suggests that storage space is unlikely to be a major issue. For instance, the Bing Search app has a download size of 24MB, whereas typical entry-level smartphones generally have an internal memory of at least 64GB (that can often be extended to more than 1TB with the addition of an SD card). The Bing Search app thus takes up less than one-thousandth of these devices’ internal storage. Granted, the Yahoo search app is slightly larger than Microsoft’s, weighing almost 100MB. But this is still insignificant compared to a modern device’s storage space.

Finally, the Commission claimed that rivals were contractually prevented from concluding exclusive pre-installation deals because Google’s own apps would also be pre-installed on devices.

However, while it is true that Google’s apps would still be present on a device, rivals could still pay for their applications to be set as default. Even Yandex – a plaintiff – recognized that this would be a valuable solution. In its own words (taken from the Commission’s decision):

Pre-installation alongside Google would be of some benefit to an alternative general search provider such as Yandex […] given the importance of default status and pre-installation on home screen, a level playing field will not be established unless there is a meaningful competition for default status instead of Google.

In short, the Commission failed to convincingly establish that Google’s contractual terms prevented as-efficient rivals from effectively distributing their applications on Android smartphones. The evidence it adduced was simply too thin to support anything close to that conclusion.

2. The threat of fragmentation

The Commission’s second theory of harm concerned the so-called “antifragmentation” agreements concluded between Google and OEMs. In a nutshell, Google only agreed to license the Google Search and Google Play apps to OEMs that sold “Android Compatible” devices (i.e. devices sold with a version of Android did not stray too far from Google’s most recent version).

According to Google, this requirement was necessary to limit the number of Android forks that were present on the market (as well as older versions of the standard Android). This, in turn, reduced development costs and prevented the Android platform from unraveling.

The Commission disagreed, arguing that Google’s anti-fragmentation provisions thwarted competition from potential Android forks (i.e. modified versions of the Android OS).

This conclusion raises at least two critical questions: The first is whether these agreements were necessary to ensure the survival and competitiveness of the Android platform, and the second is why “open” platforms should be precluded from partly replicating a feature that is essential to rival “closed” platforms, such as Apple’s iOS.

Let us start with the necessity, or not, of Google’s contractual terms. If fragmentation did indeed pose an existential threat to the Android ecosystem, and anti-fragmentation agreements averted this threat, then it is hard to make a case that they thwarted competition. The Android platform would simply not have been as viable without them.

The Commission dismissed this possibility, relying largely on statements made by Google’s rivals (many of whom likely stood to benefit from the suppression of these agreements). For instance, the Commission cited comments that it received from Yandex – one of the plaintiffs in the case:

(1166) The fact that fragmentation can bring significant benefits is also confirmed by third-party respondents to requests for information:

[…]

(2) Yandex, which stated: “Whilst the development of Android forks certainly has an impact on the fragmentation of the Android ecosystem in terms of additional development being required to adapt applications for various versions of the OS, the benefits of fragmentation outweigh the downsides…”

Ironically, the Commission relied on Yandex’s statements while, at the same time, it dismissed arguments made by Android app developers, on account that they were conflicted. In its own words:

Google attached to its Response to the Statement of Objections 36 letters from OEMs and app developers supporting Google’s views about the dangers of fragmentation […] It appears likely that the authors of the 36 letters were influenced by Google when drafting or signing those letters.

More fundamentally, the Commission’s claim that fragmentation was not a significant threat is at odds with an almost unanimous agreement among industry insiders.

For example, while it is not dispositive, a rapid search for the terms “Google Android fragmentation”, using the DuckDuckGo search engine, leads to results that cut strongly against the Commission’s conclusions. Of the ten first results, only one could remotely be construed as claiming that fragmentation was not an issue. The others paint a very different picture (below are some of the most salient excerpts):

“There’s a fairly universal perception that Android fragmentation is a barrier to a consistent user experience, a security risk, and a challenge for app developers.” (here)

“Android fragmentation, a problem with the operating system from its inception, has only become more acute an issue over time, as more users clamor for the latest and greatest software to arrive on their phones.” (here)

“Android Fragmentation a Huge Problem: Study.” (here)

“Google’s Android fragmentation fix still isn’t working at all.” (here)

“Does Google care about Android fragmentation? Not now—but it should.” (here).

“This is very frustrating to users and a major headache for Google… and a challenge for corporate IT,” Gold said, explaining that there are a large number of older, not fully compatible devices running various versions of Android.” (here)

Perhaps more importantly, one might question why Google should be treated differently than rivals that operate closed platforms, such as Apple, Microsoft and Blackberry (before the last two mostly exited the Mobile OS market). By definition, these platforms limit all potential forks (because they are based on proprietary software).

The Commission argued that Apple, Microsoft and Blackberry had opted to run “closed” platforms, which gave them the right to prevent rivals from copying their software.

While this answer has some superficial appeal, it is incomplete. Android may be an open source project, but this is not true of Google’s proprietary apps. Why should it be forced to offer them to rivals who would use them to undermine its platform? The Commission did not meaningfully consider this question.

And yet, industry insiders routinely compare the fragmentation of Apple’s iOS and Google’s Android OS, in order to gage the state of competition between both firms. For instance, one commentator noted:

[T]he gap between iOS and Android users running the latest major versions of their operating systems has never looked worse for Google.

Likewise, an article published in Forbes concluded that Google’s OEMs were slow at providing users with updates, and that this might drive users and developers away from the Android platform:

For many users the Android experience isn’t as up-to-date as Apple’s iOS. Users could buy the latest Android phone now and they may see one major OS update and nothing else. […] Apple users can be pretty sure that they’ll get at least two years of updates, although the company never states how long it intends to support devices.

However this problem, in general, makes it harder for developers and will almost certainly have some inherent security problems. Developers, for example, will need to keep pushing updates – particularly for security issues – to many different versions. This is likely a time-consuming and expensive process.

To recap, the Commission’s decision paints a world that is either black or white: either firms operate closed platforms, and they are then free to limit fragmentation as they see fit, or they create open platforms, in which case they are deemed to have accepted much higher levels of fragmentation.

This stands in stark contrast to industry coverage, which suggests that users and developers of both closed and open platforms care a great deal about fragmentation, and demand that measures be put in place to address it. If this is true, then the relative fragmentation of open and closed platforms has an important impact on their competitive performance, and the Commission was wrong to reject comparisons between Google and its closed ecosystem rivals. 

3. Google’s revenue sharing agreements

The last part of the Commission’s case centered on revenue sharing agreements between Google and its OEMs/MNOs. Google paid these parties to exclusively place its search app on the homescreen of their devices. According to the Commission, these payments reduced OEMs and MNOs’ incentives to pre-install competing general search apps.

However, to reach this conclusion, the Commission had to make the critical (and highly dubious) assumption that rivals could not match Google’s payments.

To get to that point, it notably assumed that rival search engines would be unable to increase their share of mobile search results beyond their share of desktop search results. The underlying intuition appears to be that users who freely chose Google Search on desktop (Google Search & Chrome are not set as default on desktop PCs) could not be convinced to opt for a rival search engine on mobile.

But this ignores the possibility that rivals might offer an innovative app that swayed users away from their preferred desktop search engine. 

More importantly, this reasoning cuts against the Commission’s own claim that pre-installation and default placement were critical. If most users, dismiss their device’s default search app and search engine in favor of their preferred ones, then pre-installation and default placement are largely immaterial, and Google’s revenue sharing agreements could not possibly have thwarted competition (because they did not prevent users from independently installing their preferred search app). On the other hand, if users are easily swayed by default placement, then there is no reason to believe that rivals could not exceed their desktop market share on mobile phones.

The Commission was also wrong when it claimed that rival search engines were at a disadvantage because of the structure of Google’s revenue sharing payments. OEMs and MNOs allegedly lost all of their payments from Google if they exclusively placed a rival’s search app on the home screen of a single line of handsets.

The key question is the following: could Google automatically tilt the scales to its advantage by structuring the revenue sharing payments in this way? The answer appears to be no. 

For instance, it has been argued that exclusivity may intensify competition for distribution. Conversely, other scholars have claimed that exclusivity may deter entry in network industries. Unfortunately, the Commission did not examine whether Google’s revenue sharing agreements fell within this category. 

It thus provided insufficient evidence to support its conclusion that the revenue sharing agreements reduced OEMs’ (and MNOs’) incentives to pre-install competing general search apps, rather than merely increasing competition “for the market”.

4. Conclusion

To summarize, the Commission overestimated the effect that Google’s behavior might have on its rivals. It almost entirely ignored the justifications that Google put forward and relied heavily on statements made by its rivals. The result is a one-sided decision that puts undue strain on the Android Business model, while providing few, if any, benefits in return.

This is the fourth, and last, in a series of TOTM blog posts discussing the Commission’s recently published Google Android decision (the first post can be found here, and the second here, and the third here). It draws on research from a soon-to-be published ICLE white paper.

The previous parts of this series have mostly focused on the Commission’s factual and legal conclusions. However, as this blog post points out, the case’s economic underpinnings also suffer from important weaknesses.

Two problems are particularly salient: First, the economic models cited by the Commission (discussed in an official paper, but not directly in the decision) poorly match the underlying facts. Second, the Commission’s conclusions on innovation harms are out of touch with the abundant economic literature regarding the potential link between market structure and innovation.

The wrong economic models

The Commission’s Chief Economist team outlined its economic reasoning in an article published shortly after the Android decision was published. The article reveals that the Commission relied upon three economic papers to support its conclusion that Google’s tying harmed consumer welfare.

Each of these three papers attempts to address the same basic problem. Ever since the rise of the Chicago-School, it is widely accepted that a monopolist cannot automatically raise its profits by entering an adjacent market (i.e. leveraging its monopoly position), for instance through tying. This has sometimes been called the single-monopoly-profit theory. In more recent years, various scholars have refined this Chicago-School intuition, and identified instances where the theory fails.

While the single monopoly profit theory has been criticized in academic circles, it is important to note that the three papers cited by the Commission accept its basic premise. They thus attempt to show why the theory fails in the context of the Google Android case. 

Unfortunately, the assumptions upon which they rely to reach this conclusion markedly differ from the case’s fact pattern. These papers thus offer little support to the Commission’s economic conclusions.

For a start, the authors of the first paper cited by the Commission concede that their own model does not apply to the Google case:

Actual antitrust cases are fact-intensive and our model does not perfectly fit with the current Google case in one important aspect.

The authors thus rely on important modifications, lifted from a paper by Frederico Etro and Cristina Caffara (the second paper cited by the Commission), to support their conclusion that Google’s tying was anticompetitive. 

The second paper cited by the Commission, however, is equally problematic

The authors’ underlying intuition is relatively straightforward: because Google bundles its suite of Google Apps (including Search) with the Play Store, a rival search engine would have to pay a premium in order to be pre-installed and placed on the home screen, because OEMs would have to entirely forgo Google’s suite of applications. The key assumption here is that OEMs cannot obtain the Google Play app and pre-install and place favorably a rival search app

But this is simply not true of Google’s contractual terms. The best evidence is that rivals search apps have indeed concluded deals with OEMs to pre-install their search apps, without these OEMs losing access to Google’s suite of proprietary apps. Google’s contractual terms simply do not force OEMs to choose between the Google Play app and the pre-installation of a rival search app. Etro and Caffara’s model thus falls flat.

More fundamentally, even if Google’s contractual terms did prevent OEMs from pre-loading rival apps, the paper’s conclusions would still be deeply flawed. The authors essentially assume that the only way for consumers to obtain a rival app is through pre-installation. But this is a severe misreading of the prevailing market conditions. 

Users remain free to independently download rival search apps. If Google did indeed purchase exclusive pre-installation, users would not have to choose between a “full Android” device and one with a rival search app but none of Google’s apps. Instead, they could download the rival app and place it alongside Google’s applications. 

A more efficient rival could even provide side payments, of some sort, to encourage consumers to download its app. Exclusive pre-installation thus generates a much smaller advantage than Etro and Caffara assume, and their model fails to reflect this.

Finally, the third paper by Alexandre de Cornière and Greg Taylor, suffers from the exact same problem. The authors clearly acknowledge that their findings only hold if OEMs (and consumers) are effectively prevented from (pre-)installing applications that compete with Google’s apps. In their own words:

Upstream firms offer contracts to the downstream firm, who chooses which component(s) to use and then sells to consumers. For our theory to apply, the following three conditions need to hold: (i) substitutability between the two versions of B leads the downstream firm to install at most one version.

The upshot is that all three of the economic models cited by the Commission cease to be relevant in the specific context of the Google Android decision. The Commission is thus left with little to no economic evidence to support its finding of anticompetitive effects.

Critics might argue that direct downloads by consumers are but a theoretical possibility. Yet nothing could be further from the truth. Take the web browser market: The Samsung Internet Browser has more than 1 Billion downloads on Google’s Play Store. The Opera, Opera Mini and Firefox browsers each have over a 100 million downloads. The Brave browser has more than 10 million downloads, but is growing rapidly.

In short the economic papers on which the Commission relies are based on a world that does not exist. They thus fail to support the Commission’s economic findings.

An incorrect view of innovation

In its decision, the Commission repeatedly claimed that Google’s behavior stifled innovation because it prevented rivals from entering the market. However, the Commission offered no evidence to support its assumption that reduced market entry on would lead to a decrease in innovation:

(858) For the reasons set out in this Section, the Commission concludes that the tying of the Play Store and the Google Search app helps Google to maintain and strengthen its dominant position in each national market for general search services, increases barriers to entry, deters innovation and tends to harm, directly or indirectly, consumers.

(859) First, Google’s conduct makes it harder for competing general search services to gain search queries and the respective revenues and data needed to improve their services.

(861) Second, Google’s conduct increases barriers to entry by shielding Google from competition from general search services that could challenge its dominant position in the national markets for general search services:

(862) Third, by making it harder for competing general search services to gain search queries including the respective revenues and data needed to improve their services, Google’s conduct reduces the incentives of competing general search services to invest in developing innovative features, such as innovation in algorithm and user experience design.

In a nutshell, the Commission’s findings rest on the assumption that barriers to entry and more concentrated market structures necessarily reduce innovation. But this assertion is not supported by the empirical economic literature on the topic.

For example, a 2006 paper published by Richard Gilbert surveys 24 empirical studies on the topic. These studies examine the link between market structure (or firm size) and innovation. Though earlier studies tended to identify a positive relationship between concentration, as well as firm size, and innovation, more recent empirical techniques found no significant relationship. Gilbert thus suggests that:

These econometric studies suggest that whatever relationship exists at a general economy-wide level between industry structure and R&D is masked by differences across industries in technological opportunities, demand, and the appropriability of inventions.

This intuition is confirmed by another high-profile empirical paper by Aghion, Bloom, Blundell, Griffith, and Howitt. The authors identify an inverted-U relationship between competition and innovation. Perhaps more importantly, they point out that this relationship is affected by a number of sector-specific factors.

Finally, reviewing fifty years of research on innovation and market structure, Wesley Cohen concludes that:

Even before one controls for industry effects, the variance in R&D intensity explained by market concentration is small. Moreover, whatever relationship that exists in cross sections becomes imperceptible with the inclusion of controls for industry characteristics, whether expressed as industry fixed effects or in the form of survey-based and other measures of industry characteristics such as technological opportunity, appropriability conditions, and demand. In parallel to a decades-long accumulation of mixed results, theorists have also spawned an almost equally voluminous and equivocal literature on the link between market structure and innovation.[16]

The Commission’s stance is further weakened by the fact that investments in the Android operating system are likely affected by a weak appropriability regime. In other words, because of its open source nature, it is hard for Google to earn a return on investments in the Android OS (anyone can copy, modify and offer their own version of the OS). 

Loosely tying Google’s proprietary applications to the OS is arguably one way to solve this appropriability problem. Unfortunately, the Commission brushed these considerations aside. It argued that Google could earn some revenue from the Google Play app, as well as other potential venues. However, the Commission did not question whether these sources of income were even comparable to the sums invested by Google in the Android OS. It is thus possible that the Commission’s decision will prevent Google from earning a positive return on some future investments in the Android OS, ultimately causing it to cut back its investments and slowing innovation.

The upshot is that the Commission was simply wrong to assume that barriers to entry and more concentrated market structures would necessarily reduce innovation. This is especially true, given that Google may struggle to earn a return on its investments, absent the contractual provisions challenged by the Commission.

Conclusion

In short, the Commission’s economic analysis was severely lacking. It relied on economic models that had little to say about the market it which Google and its rivals operated. Its decisions thus reveals the inherent risk of basing antitrust decisions upon overfitted economic models. 

As if that were not enough, the Android decision also misrepresents the economic literature concerning the link (or absence thereof) between market structure and innovation. As a result, there is no reason to believe that Google’s behavior reduced innovation.

[TOTM: The following is part of a digital symposium by TOTM guests and authors on the law, economics, and policy of the antitrust lawsuits against Google. The entire series of posts is available here.]

U.S. antitrust regulators have a history of narrowly defining relevant markets—often to the point of absurdity—in order to create market power out of thin air. The Federal Trade Commission (FTC) famously declared that Whole Foods and Wild Oats operated in the “premium natural and organic supermarkets market”—a narrowly defined market designed to exclude other supermarkets carrying premium natural and organic foods, such as Walmart and Kroger. Similarly, for the Staples-Office Depot merger, the FTC

narrowly defined the relevant market as “office superstore” chains, which excluded general merchandisers such as Walmart, K-Mart and Target, who at the time accounted for 80% of office supply sales.

Texas Attorney General Ken Paxton’s complaint against Google’s advertising business, joined by the attorneys general of nine other states, continues this tradition of narrowing market definition to shoehorn market dominance where it may not exist.

For example, one recent paper critical of Google’s advertising business narrows the relevant market first from media advertising to digital advertising, then to the “open” supply of display ads and, finally, even further to the intermediation of the open supply of display ads. Once the market has been sufficiently narrowed, the authors conclude Google’s market share is “perhaps sufficient to confer market power.”

While whittling down market definitions may achieve the authors’ purpose of providing a roadmap to prosecute Google, one byproduct is a mishmash of market definitions that generates as many as 16 relevant markets for digital display and video advertising, in many of which Google doesn’t have anything approaching market power (and in some of which, in fact, Facebook, and not Google, is the most dominant player).

The Texas complaint engages in similar relevant-market gerrymandering. It claims that, within digital advertising, there exist several relevant markets and that Google monopolizes four of them:

  1. Publisher ad servers, which manage the inventory of a publisher’s (e.g., a newspaper’s website or a blog) space for ads;
  2. Display ad exchanges, the “marketplace” in which auctions directly match publishers’ selling of ad space with advertisers’ buying of ad space;
  3. Display ad networks, which are similar to exchanges, except a network acts as an intermediary that collects ad inventory from publishers and sells it to advertisers; and
  4. Display ad-buying tools, which include demand-side platforms that collect bids for ad placement with publishers.

The complaint alleges, “For online publishers and advertisers alike, the different online advertising formats are not interchangeable.” But this glosses over a bigger challenge for the attorneys general: Is online advertising a separate relevant market from offline advertising?

Digital advertising, of which display advertising is a small part, is only one of many channels through which companies market their products. About half of today’s advertising spending in the United States goes to digital channels, up from about 10% a decade ago. Approximately 30% of ad spending goes to television, with the remainder going to radio, newspapers, magazines, billboards and other “offline” forms of media.

Physical newspapers now account for less than 10% of total advertising spending. Traditionally, newspapers obtained substantial advertising revenues from classified ads. As internet usage increased, newspaper classifieds have been replaced by less costly and more effective internet classifieds—such as those offered by Craigslist—or targeted ads on Google Maps or Facebook.

The price of advertising has fallen steadily over the past decade, while output has risen. Spending on digital advertising in the United States grew from $26 billion in 2010 to nearly $130 billion in 2019, an average increase of 20% a year. Over the same period, the producer price index (PPI) for internet advertising sales declined by nearly 40%. Rising spending in the face of falling prices indicates the number of ads bought and sold increased by approximately 27% a year.

Since 2000, advertising spending has been falling as a share of gross domestic product, with online advertising growing as a share of that. The combination of increasing quantity, decreasing cost and increasing total revenues are consistent with a growing and increasingly competitive market, rather than one of rising concentration and reduced competition.

There is little or no empirical data evaluating the extent to which online and offline advertising constitute distinct markets or the extent to which digital display is a distinct submarket of online advertising. As a result, analysis of adtech competition has relied on identifying several technical and technological factors—as well as the say-so of participants in the business—that the analysts assert distinguish online from offline and establish digital display (versus digital search) as a distinct submarket. This approach has been used and accepted, especially in cases in which pricing data has not been available.

But the pricing information that is available raises questions about the extent to which online advertising is a distinct market from offline advertising. For example, Avi Goldfarb and Catherine Tucker find that, when local regulations prohibit offline direct advertising, search advertising is more expensive, indicating that search and offline advertising are substitutes. In other research, they report that online display advertising circumvents, in part, local bans on offline billboard advertising for alcoholic beverages. In both studies, Goldfarb and Tucker conclude their results suggest online and offline advertising are substitutes. They also conclude this substitution suggests that online and offline markets should be considered together in the context of antitrust.

While this information is not sufficient to define a broader relevant market, it raises questions regarding solely relying on the technical or technological distinctions and the say-so of market participants.

In the United States, plaintiffs do not get to define the relevant market. That is up to the judge or the jury. Plaintiffs have the burden to convince the court that a proposed narrow market definition is the correct one. With strong evidence that online and offline ads are substitutes, the court should not blindly accept the gerrymandered market definitions posited by the attorneys general.

In mid-November, the 50 state attorneys general (AGs) investigating Google’s advertising practices expanded their antitrust probe to include the company’s search and Android businesses. Texas Attorney General Ken Paxton, the lead on the case, was supportive of the development, but made clear that other states would manage the investigations of search and Android separately. While attorneys might see the benefit in splitting up search and advertising investigations, platforms like Google need to be understood as a coherent whole. If the state AGs case is truly concerned with the overall impact on the welfare of consumers, it will need to be firmly grounded in the unique economics of this platform.

Back in September, 50 state AGs, including those in Washington, DC and Puerto Rico, announced an investigation into Google. In opening the case, Paxton said that, “There is nothing wrong with a business becoming the biggest game in town if it does so through free market competition, but we have seen evidence that Google’s business practices may have undermined consumer choice, stifled innovation, violated users’ privacy, and put Google in control of the flow and dissemination of online information.” While the original document demands focused on Google’s “overarching control of online advertising markets and search traffic,” reports since then suggest that the primary investigation centers on online advertising.

Defining the market

Since the market definition is the first and arguably the most important step in an antitrust case, Paxton has tipped his hand and shown that the investigation is converging on the online ad market. Yet, he faltered when he wrote in The Wall Street Journal that, “Each year more than 90% of Google’s $117 billion in revenue comes from online advertising. For reference, the entire market for online advertising is around $130 billion annually.” As Patrick Hedger of the Competitive Enterprise Institute was quick to note, Paxton cited global revenue numbers and domestic advertising statistics. In reality, Google’s share of the online advertising market in the United States is 37 percent and is widely expected to fall.

When Google faced scrutiny by the Federal Trade Commission in 2013, the leaked staff report explained that “the Commission and the Department of Justice have previously found online ‘search advertising’ to be a distinct product market.” This finding, which dates from 2007, simply wouldn’t stand today. Facebook’s ad platform was launched in 2007 and has grown to become a major competitor to Google. Even more recently, Amazon has jumped into the space and independent platforms like Telaria, Rubicon Project, and The Trade Desk have all made inroads. In contrast to the late 2000s, advertisers now use about four different online ad platforms.

Moreover, the relationship between ad prices and industry concentration is complicated. In traditional economic analysis, fewer suppliers of a product generally translates into higher prices. In the online ad market, however, fewer advertisers means that ad buyers can efficiently target people through keywords. Because advertisers have access to superior information, research finds that more concentration tends to lead to lower search engine revenues. 

The addition of new fronts in the state AGs’ investigation could spell disaster for consumers. While search and advertising are distinct markets, it is the act of tying the two together that makes platforms like Google valuable to users and advertisers alike. Demand is tightly integrated between the two sides of the platform. Changes in user and advertiser preferences have far outsized effects on the overall platform value because each side responds to the other. If users experience an increase in price or a reduction in quality, then they will use the platform less or just log off completely. Advertisers see this change in users and react by reducing their demand for ad placements as well. When advertisers drop out, the total amount of content also recedes and users react once again. Economists call these relationships demand interdependencies. The demand on one side of the market is interdependent with demand on the other. Research on magazines, newspapers, and social media sites all support the existence of demand interdependencies. 

Economists David Evans and Richard Schmalensee, who were cited extensively in the Supreme Court case Ohio v. American Express, explained the importance of their integration into competition analysis, “The key point is that it is wrong as a matter of economics to ignore significant demand interdependencies among the multiple platform sides” when defining markets. If they are ignored, then the typical analytical tools will yield incorrect assessments. Understanding these relationships makes the investigation all that more difficult.

The limits of remedies

Most likely, this current investigation will follow the trajectory of Microsoft in the 1990s when states did the legwork for a larger case brought by the Department of Justice (DoJ). The DoJ already has its own investigation into Google and will probably pull together all of the parties for one large suit. Google is also subject to a probe by the House of Representatives Judiciary Committee as well. What is certain is that Google will be saddled with years of regulatory scrutiny, but what remains unclear is what kind of changes the AGs are after.

The investigation might aim to secure behavioral changes, but these often come with a cost in platform industries. The European Commission, for example, got Google to change its practices with its Android operating system for mobile phones. Much like search and advertising, the Android ecosystem is a platform with cross subsidization and demand interdependencies between the various sides of the market. Because the company was ordered to stop tying the Android operating system to apps, manufacturers of phones and tablets now have to pay a licensing fee in Europe if they want Google’s apps and the Play Store. Remedies meant to change one side of the platform resulted in those relationships being unbundled. When regulators force cross subsidization to become explicit prices, consumers are the one who pay.

The absolute worst case scenario would be a break up of Google, which has been a centerpiece of Senator Elizabeth Warren’s presidential platform. As I explained last year, that would be a death warrant for the company:

[T]he value of both Facebook and Google comes in creating the platform, which combines users with advertisers. Before the integration of ad networks, the search engine industry was struggling and it was simply not a major player in the Internet ecosystem. In short, the search engines, while convenient, had no economic value. As Michael Moritz, a major investor of Google, said of those early years, “We really couldn’t figure out the business model. There was a period where things were looking pretty bleak.” But Google didn’t pave the way. Rather, Bill Gross at GoTo.com succeeded in showing everyone how advertising could work to build a business. Google founders Larry Page and Sergey Brin merely adopted the model in 2002 and by the end of the year, the company was profitable for the first time. Marrying the two sides of the platform created value. Tearing them apart will also destroy value.

The state AGs need to resist making this investigation into a political showcase. As Pew noted in documenting the rise of North Carolina Attorney General Josh Stein to national prominence, “What used to be a relatively high-profile position within a state’s boundaries has become a springboard for publicity across the country.” While some might cheer the opening of this investigation, consumer welfare needs to be front and center. To properly understand how consumer welfare might be impacted by an investigation, the state AGs need to take seriously the path already laid out by platform economics. For the sake of consumers, let’s hope they are up to the task. 

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

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

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

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

​​Relevant market

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

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

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

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

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

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

Offline advertising vs. online advertising

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

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

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

Display ads vs. search ads

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

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

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

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

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

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

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

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

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

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

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

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

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

This is the second in a series of TOTM blog posts discussing the Commission’s recently published Google Android decision (the first post can be found here). It draws on research from a soon-to-be published ICLE white paper.

(Left, Android 10 Website; Right, iOS 13 Website)

In a previous post, I argued that the Commission failed to adequately define the relevant market in its recently published Google Android decision

This improper market definition might not be so problematic if the Commission had then proceeded to undertake a detailed (and balanced) assessment of the competitive conditions that existed in the markets where Google operates (including the competitive constraints imposed by Apple). 

Unfortunately, this was not the case. The following paragraphs respond to some of the Commission’s most problematic arguments regarding the existence of barriers to entry, and the absence of competitive constraints on Google’s behavior.

The overarching theme is that the Commission failed to quantify its findings and repeatedly drew conclusions that did not follow from the facts cited. As a result, it was wrong to conclude that Google faced little competitive pressure from Apple and other rivals.

1. Significant investments and network effects ≠ barriers to entry

In its decision, the Commission notably argued that significant investments (millions of euros) are required to set up a mobile OS and App store. It also argued that market for licensable mobile operating systems gave rise to network effects. 

But contrary to the Commission’s claims, neither of these two factors is, in and of itself, sufficient to establish the existence of barriers to entry (even under EU competition law’s loose definition of the term, rather than Stigler’s more technical definition)

Take the argument that significant investments are required to enter the mobile OS market.

The main problem is that virtually every market requires significant investments on the part of firms that seek to enter. Not all of these costs can be seen as barriers to entry, or the concept would lose all practical relevance. 

For example, purchasing a Boeing 737 Max airplane reportedly costs at least $74 million. Does this mean that incumbents in the airline industry are necessarily shielded from competition? Of course not. 

Instead, the relevant question is whether an entrant with a superior business model could access the capital required to purchase an airplane and challenge the industry’s incumbents.

Returning to the market for mobile OSs, the Commission should thus have questioned whether as-efficient rivals could find the funds required to produce a mobile OS. If the answer was yes, then the investments highlighted by the Commission were largely immaterial. As it happens, several firms have indeed produced competing OSs, including CyanogenMod, LineageOS and Tizen.

The same is true of Commission’s conclusion that network effects shielded Google from competitors. While network effects almost certainly play some role in the mobile OS and app store markets, it does not follow that they act as barriers to entry in competition law terms. 

As Paul Belleflamme recently argued, it is a myth that network effects can never be overcome. And as I have written elsewhere, the most important question is whether users could effectively coordinate their behavior and switch towards a superior platform, if one arose (See also Dan Spulber’s excellent article on this point).

The Commission completely ignored this critical interrogation during its discussion of network effects.

2. The failure of competitors is not proof of barriers to entry

Just as problematically, the Commission wrongly concluded that the failure of previous attempts to enter the market was proof of barriers to entry. 

This is the epitome of the Black Swan fallacy (i.e. inferring that all swans are white because you have never seen a relatively rare, but not irrelevant, black swan).

The failure of rivals is equally consistent with any number of propositions: 

  • There were indeed barriers to entry; 
  • Google’s products were extremely good (in ways that rivals and the Commission failed to grasp); 
  • Google responded to intense competitive pressure by continuously improving its product (and rivals thus chose to stay out of the market); 
  • Previous rivals were persistently inept (to take the words of Oliver Williamson); etc. 

The Commission did not demonstrate that its own inference was the right one, nor did it even demonstrate any awareness that other explanations were at least equally plausible.

3. First mover advantage?

Much of the same can be said about the Commission’s observation that Google enjoyed a first mover advantage

The elephant in the room is that Google was not the first mover in the smartphone market (and even less so in the mobile phone industry). The Commission attempted to sidestep this uncomfortable truth by arguing that Google was the first mover in the Android app store market. It then concluded that Google had an advantage because users were familiar with Android’s app store.

To call this reasoning “naive” would be too kind. Maybe consumers are familiar with Google’s products today, but they certainly weren’t when Google entered the market. 

Why would something that did not hinder Google (i.e. users’ lack of familiarity with its products, as opposed to those of incumbents such as Nokia or Blackberry) have the opposite effect on its future rivals? 

Moreover, even if rivals had to replicate Android’s user experience (and that of its app store) to prove successful, the Commission did not show that there was anything that prevented them from doing so — a particularly glaring omission given the open-source nature of the Android OS.

The result is that, at best, the Commission identified a correlation but not causality. Google may arguably have been the first, and users might have been more familiar with its offerings, but this still does not prove that Android flourished (and rivals failed) because of this.

4. It does not matter that users “do not take the OS into account” when they purchase a device

The Commission also concluded that alternatives to Android (notably Apple’s iOS and App Store) exercised insufficient competitive constraints on Google. Among other things, it argued that this was because users do not take the OS into account when they purchase a smartphone (so Google could allegedly degrade Android without fear of losing users to Apple)..

In doing so, the Commission failed to grasp that buyers might base their purchases on a devices’ OS without knowing it.

Some consumers will simply follow the advice of a friend, family member or buyer’s guide. Acutely aware of their own shortcomings, they thus rely on someone else who does take the phone’s OS into account. 

But even when they are acting independently, unsavvy consumers may still be driven by technical considerations. They might rely on a brand’s reputation for providing cutting edge devices (which, per the Commission, is the most important driver of purchase decisions), or on a device’s “feel” when they try it in a showroom. In both cases, consumers’ choices could indirectly be influenced by a phone’s OS.

In more technical terms, a phone’s hardware and software are complementary goods. In these settings, it is extremely difficult to attribute overall improvements to just one of the two complements. For instance, a powerful OS and chipset are both equally necessary to deliver a responsive phone. The fact that consumers may misattribute a device’s performance to one of these two complements says nothing about their underlying contribution to a strong end-product (which, in turn, drives purchase decisions). Likewise, battery life is reportedly one of the most important features for users, yet few realize that a phone’s OS has a large impact on it.

Finally, if consumers were really indifferent to the phone’s operating system, then the Commission should have dropped at least part of its case against Google. The Commission’s claim that Google’s anti-fragmentation agreements harmed consumers (by reducing OS competition) has no purchase if Android is provided free of charge and consumers are indifferent to non-price parameters, such as the quality of a phone’s OS. 

5. Google’s users were not “captured”

Finally, the Commission claimed that consumers are loyal to their smartphone brand and that competition for first time buyers was insufficient to constrain Google’s behavior against its “captured” installed base.

It notably found that 82% of Android users stick with Android when they change phones (compared to 78% for Apple), and that 75% of new smartphones are sold to existing users. 

The Commission asserted, without further evidence, that these numbers proved there was little competition between Android and iOS.

But is this really so? In almost all markets consumers likely exhibit at least some loyalty to their preferred brand. At what point does this become an obstacle to interbrand competition? The Commission offered no benchmark mark against which to assess its claims.

And although inter-industry comparisons of churn rates should be taken with a pinch of salt, it is worth noting that the Commission’s implied 18% churn rate for Android is nothing out of the ordinary (see, e.g., here, here, and here), including for industries that could not remotely be called anticompetitive.

To make matters worse, the Commission’s own claimed figures suggest that a large share of sales remained contestable (roughly 39%).

Imagine that, every year, 100 devices are sold in Europe (75 to existing users and 25 to new users, according to the Commission’s figures). Imagine further that the installed base of users is split 76–24 in favor of Android. Under the figures cited by the Commission, it follows that at least 39% of these sales are contestable.

According to the Commission’s figures, there would be 57 existing Android users (76% of 75) and 18 Apple users (24% of 75), of which roughly 10 (18%) and 4 (22%), respectively, switch brands in any given year. There would also be 25 new users who, even according to the Commission, do not display brand loyalty. The result is that out of 100 purchasers, 25 show no brand loyalty and 14 switch brands. And even this completely ignores the number of consumers who consider switching but choose not to after assessing the competitive options.

Conclusion

In short, the preceding paragraphs argue that the Commission did not meet the requisite burden of proof to establish Google’s dominance. Of course, it is one thing to show that the Commission’s reasoning was unsound (it is) and another to establish that its overall conclusion was wrong.

At the very least, I hope these paragraphs will convey a sense that the Commission loaded the dice, so to speak. Throughout the first half of its lengthy decision, it interpreted every piece of evidence against Google, drew significant inferences from benign pieces of information, and often resorted to circular reasoning.

The following post in this blog series argues that these errors also permeate the Commission’s analysis of Google’s allegedly anticompetitive behavior.
