Is Google Search Bias Consistent with Anticompetitive Foreclosure?

Posted by Josh Wright on December 9, 2011

In my series of three posts (here, here and here) drawn from my empirical study on search bias I have examined whether search bias exists, and, if so, how frequently it occurs.  This, the final post in the series, assesses the results of the study (as well as the Edelman & Lockwood (E&L) study to which it responds) to determine whether the own-content bias I’ve identified is in fact consistent with anticompetitive foreclosure or is otherwise sufficient to warrant antitrust intervention.

As I’ve repeatedly emphasized, while I refer to differences among search engines’ rankings of their own or affiliated content as “bias,” without more these differences do not imply anticompetitive conduct.  It is wholly unsurprising and indeed consistent with vigorous competition among engines that differentiation emerges with respect to algorithms.  However, it is especially important to note that the theories of anticompetitive foreclosure raised by Google’s rivals involve very specific claims about these differences.  Properly articulated vertical foreclosure theories proffer both that bias is (1) sufficient in magnitude to exclude Google’s rivals from achieving efficient scale, and (2) actually directed at Google’s rivals.  Unfortunately for search engine critics, their theories fail on both counts.  The observed own-content bias appears neither to be extensive enough to prevent rivals from gaining access to distribution nor does it appear to target Google’s rivals; rather, it seems to be a natural result of intense competition between search engines and of significant benefit to consumers.

Vertical foreclosure arguments are premised upon the notion that rivals are excluded with sufficient frequency and intensity as to render their efforts to compete for distribution uneconomical.  Yet the empirical results simply do not indicate that market conditions are in fact conducive to the types of harmful exclusion contemplated by application of the antitrust laws.  Rather, the evidence indicates that (1) the absolute level of search engine “bias” is extremely low, and (2) “bias” is not a function of market power, but an effective strategy that has arisen as a result of serious competition and innovation between and by search engines.  The first finding undermines competitive foreclosure arguments on their own terms, that is, even if there were no pro-consumer justifications for the integration of Google content with Google search results.  The second finding, even more importantly, reveals that the evolution of consumer preferences for more sophisticated and useful search results has driven rival search engines to satisfy that demand.  Both Bing and Google have shifted toward these results, rendering the complained-of conduct equivalent to satisfying the standard of care in the industry–not restraining competition.

A significant lack of search bias emerges in the representative sample of queries.  This result is entirely unsurprising, given that bias is relatively infrequent even in E&L’s sample of queries specifically designed to identify maximum bias.  In the representative sample, the total percentage of queries for which Google references its own content when rivals do not is even lower—only about 8%—meaning that Google favors its own content far less often than critics have suggested.  This fact is crucial and highly problematic for search engine critics, as their burden in articulating a cognizable antitrust harm includes not only demonstrating that bias exists, but further that it is actually competitively harmful.  As I’ve discussed, bias alone is simply not sufficient to demonstrate any prima facie anticompetitive harm as it is far more often procompetitive or competitively neutral than actively harmful.  Moreover, given that bias occurs in less than 10% of queries run on Google, anticompetitive exclusion arguments appear unsustainable.

Indeed, theories of vertical foreclosure find virtually zero empirical support in the data.  Moreover, it appears that, rather than being a function of monopolistic abuse of power, search bias has emerged as an efficient competitive strategy, allowing search engines to differentiate their products in ways that benefit consumers.  I find that when search engines do reference their own content on their search results pages, it is generally unlikely that another engine will reference this same content.  However, the fact that both this percentage and the absolute level of own content inclusion is similar across engines indicates that this practice is not a function of market power (or its abuse), but is rather an industry standard.  In fact, despite conducting a much smaller percentage of total consumer searches, Bing is consistently more biased than Google, illustrating that the benefits search engines enjoy from integrating their own content into results is not necessarily a function of search engine size or volume of queries.  These results are consistent with a business practice that is efficient and at significant tension with arguments that such integration is designed to facilitate competitive foreclosure.

How Much Search Bias Is There?

Posted by Josh Wright on November 22, 2011

My last two posts on search bias (here and here) have analyzed and critiqued Edelman & Lockwood’s small study on search bias.  This post extends this same methodology and analysis to a random sample of 1,000 Google queries (released by AOL in 2006), to develop a more comprehensive understanding of own-content bias.  As I’ve stressed, these analyses provide useful—but importantly limited—glimpses into the nature of the search engine environment.  While these studies are descriptively helpful, actual harm to consumer welfare must always be demonstrated before cognizable antitrust injuries arise.  And naked identifications of own-content bias simply do not inherently translate to negative effects on consumers (see, e.g., here and here for more comprehensive discussion).

Now that’s settled, let’s jump into the results of the 1,000 random search query study.

How Do Search Engines Rank Their Own Content?

Consistent with our earlier analysis, a starting off point for thinking about measuring differentiation among search engines with respect to placing their own content is to compare how a search engine ranks its own content relative to how other engines place that same content (e.g. to compare how Google ranks “Google Maps” relative to how Bing or Blekko rank it).   Restricting attention exclusively to the first or “top” position, I find that Google simply does not refer to its own content in over 90% of queries.  Similarly, Bing does not reference Microsoft content in 85.4% of queries.  Google refers to its own content in the first position when other search engines do not in only 6.7% of queries; while Bing does so over twice as often, referencing Microsoft content that no other engine references in the first position in 14.3% of queries.  The following two charts illustrate the percentage of Google or Bing first position results, respectively, dedicated to own content across search engines.

The most striking aspect of these results is the small fraction of queries for which placement of own-content is relevant.  The results are similar when I expand consideration to the entire first page of results; interestingly, however, while the levels of own-content bias are similar considering the entire first page of results, Bing is far more likely than Google to reference its own content in its very first results position.

Examining Search Engine “Bias” on Google

Two distinct differences between the results of this larger study and my replication of Edelman & Lockwood emerge: (1) Google and Bing refer to their own content in a significantly smaller percentage of cases here than in the non-random sample; and (2) in general, when Google or Bing does rank its own content highly, rival engines are unlikely to similarly rank that same content.

The following table reports the percentages of queries for which Google’s ranking of its own content and its rivals’ rankings of that same content differ significantly. When Google refers to its own content within its Top 5 results, at least one other engine similarly ranks this content for only about 5% of queries.

The following table presents the likelihood that Google content will appear in a Google search, relative to searches conducted on rival engines (reported in odds ratios).

The first and third columns report results indicating that Google affiliated content is more likely to appear in a search executed on Google rather than rival engines.  Google is approximately 16 times more likely to refer to its own content on its first page as is any other engine.  Bing and Blekko are both significantly less likely to refer to Google content in their first result or on their first page than Google is to refer to Google content within these same parameters.  In each iteration, Bing is more likely to refer to Google content than is Blekko, and in the case of the first result, Bing is much more likely to do so.  Again, to be clear, the fact that Bing is more likely to rank its own content is not suggestive that the practice is problematic.  Quite the contrary, the demonstration that firms both with and without market power in search (to the extent that is a relevant antitrust market) engage in similar conduct the correct inference is that there must be efficiency explanations for the practice.  The standard response, of course, is that the competitive implications of a practice are different when a firm with market power does it.  That’s not exactly right.  It is true that firms with market power can engage in conduct that gives rise to potential antitrust problems when the same conduct from a firm without market power would not; however, when firms without market power engage in the same business practice it demands that antitrust analysts seriously consider the efficiency implications of the practice.  In other words, there is nothing in the mantra that things are “different” when larger firms do them that undercut potential efficiency explanations.

Examining Search Engine “Bias” on Bing

For queries within the larger sample, Bing refers to Microsoft content within its Top 1 and 3 results when no other engine similarly references this content for a slightly smaller percentage of queries than in my Edelman & Lockwood replication.  Yet Bing continues to exhibit a strong tendency to rank Microsoft content more prominently than rival engines.  For example, when Bing refers to Microsoft content within its Top 5 results, other engines agree with this ranking for less than 2% of queries; and Bing refers to Microsoft content that no other engine does within its Top 3 results for 99.2% of queries:

Regression analysis further illustrates Bing’s propensity to reference Microsoft content that rivals do not.  The following table reports the likelihood that Microsoft content is referred to in a Bing search as compared to searches on rival engines (again reported in odds ratios).

Bing refers to Microsoft content in its first results position about 56 times more often than rival engines refer to Microsoft content in this same position.  Across the entire first page, Microsoft content appears on a Bing search about 25 times more often than it does on any other engine.  Both Google and Blekko are accordingly significantly less likely to reference Microsoft content.  Notice further that, contrary to the findings in the smaller study, Google is slightly less likely to return Microsoft content than is Blekko, both in its first results position and across its entire first page.

A Closer Look at Google v. Bing

 Consistent with the smaller sample, I find again that Bing is more biased than Google using these metrics.  In other words, Bing ranks its own content significantly more highly than its rivals do more frequently then Google does, although the discrepancy between the two engines is smaller here than in the study of Edelman & Lockwood’s queries.  As noted above, Bing is over twice as likely to refer to own content in first results position than is Google.

Figures 7 and 8 present the same data reported above, but with Blekko removed, to allow for a direct visual comparison of own-content bias between Google and Bing.

Consistent with my earlier results, Bing appears to consistently rank Microsoft content higher than Google ranks the same (Microsoft) content more frequently than Google ranks Google content more prominently than Bing ranks the same (Google) content.

This result is particularly interesting given the strength of the accusations condemning Google for behaving in precisely this way.  That Bing references Microsoft content just as often as—and frequently even more often than!—Google references its own content strongly suggests that this behavior is a function of procompetitive product differentiation, and not abuse of market power.  But I’ll save an in-depth analysis of this issue for my next post, where I’ll also discuss whether any of the results reported in this series of posts support anticompetitive foreclosure theories or otherwise suggest antitrust intervention is warranted.

Extending & Rebutting Edelman & Lockwood on Search Bias

Posted by Josh Wright on November 9, 2011

In my last post, I discussed Edelman & Lockwood’s (E&L’s) attempt to catch search engines in the act of biasing their results—as well as their failure to actually do so.  In this post, I present my own results from replicating their study.  Unlike E&L, I find that Bing is consistently more biased than Google, for reasons discussed further below, although neither engine references its own content as frequently as E&L suggest.

I ran searches for E&L’s original 32 non-random queries using three different search engines—Google, Bing, and Blekko—between June 23 and July 5 of this year.  This replication is useful, as search technology has changed dramatically since E&L recorded their results in August 2010.  Bing now powers Yahoo, and Blekko has had more time to mature and enhance its results.  Blekko serves as a helpful “control” engine in my study, as it is totally independent of Google and Microsoft, and so has no incentive to refer to Google or Microsoft content unless it is actually relevant to users.  In addition, because Blekko’s model is significantly different than Google and Microsoft’s, if results on all three engines agree that specific content is highly relevant to the user query, it lends significant credibility to the notion that the content places well on the merits rather than being attributable to bias or other factors.

How Do Search Engines Rank Their Own Content?

Focusing solely upon the first position, Google refers to its own products or services when no other search engine does in 21.9% of queries; in another 21.9% of queries, both Google and at least one other search engine rival (i.e. Bing or Blekko) refer to the same Google content with their first links.

But restricting focus upon the first position is too narrow.  Assuming that all instances in which Google or Bing rank their own content first and rivals do not amounts to bias would be a mistake; such a restrictive definition would include cases in which all three search engines rank the same content prominently—agreeing that it is highly relevant—although not all in the first position. 

The entire first page of results provides a more informative comparison.  I find that Google and at least one other engine return Google content on the first page of results in 7% of the queries.  Google refers to its own content on the first page of results without agreement from either rival search engine in only 7.9% of the queries.  Meanwhile, Bing and at least one other engine refer to Microsoft content in 3.2% of the queries.  Bing references Microsoft content without agreement from either Google or Blekko in 13.2% of the queries:

This evidence indicates that Google’s ranking of its own content differs significantly from its rivals in only 7.9% of queries, and that when Google ranks its own content prominently it is generally perceived as relevant.  Further, these results suggest that Bing’s organic search results are significantly more biased in favor of Microsoft content than Google’s search results are in favor of Google’s content.

Examining Search Engine “Bias” on Google

The following table presents the percentages of queries for which Google’s ranking of its own content differs significantly from its rivals’ ranking of that same content.

Note that percentages below 50 in this table indicate that rival search engines generally see the referenced Google content as relevant and independently believe that it should be ranked similarly.

So when Google ranks its own content highly, at least one rival engine typically agrees with this ranking; for example, when Google places its own content in its Top 3 results, at least one rival agrees with this ranking in over 70% of queries.  Bing especially agrees with Google’s rankings of Google content within its Top 3 and 5 results, failing to include Google content that Google ranks similarly in only a little more than a third of queries.

Examining Search Engine “Bias” on Bing

Bing refers to Microsoft content in its search results far more frequently than its rivals reference the same Microsoft content.  For example, Bing’s top result references Microsoft content for 5 queries, while neither Google nor Blekko ever rank Microsoft content in the first position:

This table illustrates the significant discrepancies between Bing’s treatment of its own Microsoft content relative to Google and Blekko.  Neither rival engine refers to Microsoft content Bing ranks within its Top 3 results; Google and Blekko do not include any Microsoft content Bing refers to on the first page of results in nearly 80% of queries.

Moreover, Bing frequently ranks Microsoft content highly even when rival engines do not refer to the same content at all in the first page of results.  For example, of the 5 queries for which Bing ranks Microsoft content in its top result, Google refers to only one of these 5 within its first page of results, while Blekko refers to none.  Even when comparing results across each engine’s full page of results, Google and Blekko only agree with Bing’s referral of Microsoft content in 20.4% of queries.

Although there are not enough Bing data to test results in the first position in E&L’s sample, Microsoft content appears as results on the first page of a Bing search about 7 times more often than Microsoft content appears on the first page of rival engines.  Also, Google is much more likely to refer to Microsoft content than Blekko, though both refer to significantly less Microsoft content than Bing.

A Closer Look at Google v. Bing

On E&L’s own terms, Bing results are more biased than Google results; rivals are more likely to agree with Google’s algorithmic assessment (than with Bing’s) that its own content is relevant to user queries.  Bing refers to Microsoft content other engines do not rank at all more often than Google refers its own content without any agreement from rivals.  Figures 1 and 2 display the same data presented above in order to facilitate direct comparisons between Google and Bing.

As Figures 1 and 2 illustrate, Bing search results for these 32 queries are more frequently “biased” in favor of its own content than are Google’s.  The bias is greatest for the Top 1 and Top 3 search results.

My study finds that Bing exhibits far more “bias” than E&L identify in their earlier analysis.  For example, in E&L’s study, Bing does not refer to Microsoft content at all in its Top 1 or Top 3 results; moreover, Bing refers to Microsoft content within its entire first page 11 times, while Google and Yahoo refer to Microsoft content 8 and 9 times, respectively.  Most likely, the significant increase in Bing’s “bias” differential is largely a function of Bing’s introduction of localized and personalized search results and represents serious competitive efforts on Bing’s behalf.

Again, it’s important to stress E&L’s limited and non-random sample, and to emphasize the danger of making strong inferences about the general nature or magnitude of search bias based upon these data alone.  However, the data indicate that Google’s own-content bias is relatively small even in a sample collected precisely to focus upon the queries most likely to generate it.  In fact—as I’ll discuss in my next post—own-content bias occurs even less often in a more representative sample of queries, strongly suggesting that such bias does not raise the competitive concerns attributed to it.

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

Posted by Josh Wright on November 8, 2011

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Google, Vertical Integration, and Beer

Posted by Josh Wright on October 20, 2011

First, Google had the audacity to include a map in search queries suggesting a user wanted a map.  Consumers liked it.  Then came video.  Then, they came for the beer:

Google’s first attempt at brewing has resulted in a beer that taps ingredients from all across the globe. They teamed up with Delaware craft brewery Dogfish Head to make “URKontinent,” a Belgian Dubbel style beer with flavors from five different continents.

No word yet from the Google’s antitrust-wielding critics whether integration into beer will exclude rivals who vertical search engines who, without access to the beer, have no chance to compete.  Yes, there are specialized beer search sites if you must know (or local beer search).  Or small breweries who, because of Google’s market share in search, cannot compete against Dogfish Head’s newest product.  But before we start the new antitrust investigation, Google has offered some new facts to clarify matters:

Similarly, the project with Dogfish Head brewery was a Googler-driven project organized by a group of craftbrewery aficionados across the company. While our Googlers had fun advising on the creation of a beer recipe, we aren’t receiving any proceeds from the sale of the beer and we have no plans to enter the beer business.

Whew.  What a relief.  But, I’m sure the critics will be watching just in case to see if Dogfish Head jumps in the search rankings.  Donating time and energy to the creation of beer is really just a gateway to more serious exclusionary conduct, right?  And Section 5 of the FTC Act applies to incipient conduct in the beer market, clearly.  Or did the DOJ get beer-related Google activities in the clearance arrangement between the agencies?

72% of Antitrust Lawyers Not Impressed By Case Against Google

Posted by Josh Wright on October 10, 2011

It is not exactly the application of the consumer welfare standard, nor a scientific survey, but nonetheless an interesting poll at the American Bar Association Antitrust & Intellectual Property Conference before and after presentations from lawyers representing each side.  The results?

While this is an admittedly small sample size and may not be representative of antitrust lawyers on a more widespread basis, a poll taken at an American Bar Association event at Stanford University reveals that nearly 3/4 of the antitrust lawyers present didn’t feel that Google was hurting competition.  The event was a debate and polling before the debate had attendees of the debate set at 61% not feeling that Google has hurt competition.  Those on the other side of the debate? Before it got underway 19% felt that Google was hurting competition and that number lowered slightly to 17% following the exchange.

Interesting results for a group of antitrust lawyers hearing out some version of the arguments likely to be made in from of the antitrust lawyers at the Federal Trade Commission.

UPDATE: Here is Manne & Wright (2011) on the case against the case against Google in the Harvard Journal of Law & Public Policy.

ACS Blog Debate on Google: Putting Consumer Welfare First in Antitrust Analysis of Google

Posted by Josh Wright on October 6, 2011

[I am participating in an online “debate” at the American Constitution Society with Professor Ben Edelman.  The debate consists of an opening statement and concluding responses to be posted later in the week.  Professor Edelman’s opening statement is here.  I am cross-posting my opening statement here at TOTM.  This is my closing statement]

Professor Edelman’s opening post does little to support his case.  Instead, it reflects the same retrograde antitrust I criticized in my first post.

Edelman’s understanding of antitrust law and economics appears firmly rooted in the 1960s approach to antitrust in which enforcement agencies, courts, and economists vigorously attacked novel business arrangements without regard to their impact on consumers.  Judge Learned Hand’s infamous passage in the Alcoa decision comes to mind as an exemplar of antitrust’s bad old days when the antitrust laws demanded that successful firms forego opportunities to satisfy consumer demand.  Hand wrote:

we can think of no more effective exclusion than progressively to embrace each new opportunity as it opened, and to face every newcomer with new capacity already geared into a great organization, having the advantage of experience, trade connections and the elite of personnel.

Antitrust has come a long way since then.  By way of contrast, today’s antitrust analysis of alleged exclusionary conduct begins with (ironically enough) the U.S. v. Microsoft decision.  Microsoft emphasizes the difficulty of distinguishing effective competition from exclusionary conduct; but it also firmly places “consumer welfare” as the lodestar of the modern approach to antitrust:

Whether any particular act of a monopolist is exclusionary, rather than merely a form of vigorous competition, can be difficult to discern: the means of illicit exclusion, like the means of legitimate competition, are myriad.  The challenge for an antitrust court lies in stating a general rule for distinguishing between exclusionary acts, which reduce social welfare, and competitive acts, which increase it.  From a century of case law on monopolization under § 2, however, several principles do emerge.  First, to be condemned as exclusionary, a monopolist’s act must have an “anticompetitive effect.”  That is, it must harm the competitive process and thereby harm consumers.  In contrast, harm to one or more competitors will not suffice.

Nearly all antitrust commentators agree that the shift to consumer-welfare focused analysis has been a boon for consumers.  Unfortunately, Edelman’s analysis consists largely of complaints that would have satisfied courts and agencies in the 1960s but would not do so now that the focus has turned to consumer welfare rather than indirect complaints about market structure or the fortunes of individual rivals.

From the start, in laying out his basic case against Google, Edelman invokes antitrust concepts that are simply inapt for the facts and then goes on to apply them in a manner inconsistent with the modern consumer-welfare-oriented framework described above:

In antitrust parlance, this is tying: A user who wants only Google Search, but not Google’s other services, will be disappointed.  Instead, any user who wants Google Search is forced to receive Google’s other services too.  Google’s approach also forecloses competition: Other sites cannot compete on their merits for a substantial portion of the market – consumers who use Google to find information – because Google has kept those consumers for itself.

There are two significant errors here.  First, Edelman claims to be interested in protecting users who want only Google Search but not its other services will be disappointed.  I have no doubt such consumers exist.  Some proof that they exist is that a service has already been developed to serve them.  Professor Edelman, meet Googleminusgoogle.com.  Across the top the page reads: “Search with Google without getting results from Google sites such as Knol, Blogger and YouTube.”  In antitrust parlance, this is not tying after all.  The critical point, however, is that user preferences are being satisfied as one would expect to arise from competition.

The second error, as I noted in my first post, is to condemn vertical integration as inherently anticompetitive.  It is here that the retrograde character of Professor Edelman’s analysis (and other critics of Google, to be fair) shines brightest.  It reflects a true disconnect between the 1960s approach to antitrust which focused exclusively upon market structure and impact upon rival websites; impact upon consumers was nowhere to be found.  That Google not only produces search results but also owns some of the results that are searched is not a problem cognizable by modern antitrust.  Edelman himself—appropriately—describes Google and its competitors as “information services.”  Google is not merely a URL finder.  Consumers demand more than that and competition forces search engines to deliver.  It offers value to users (and thus it can offer users to advertisers) by helping them find information in increasingly useful ways.  Most users “want Google Search” to the exclusion of Google’s “other services” (and, if they do, all they need do is navigate over to http://googleminusgoogle.com/ (even in a Chrome browser) and they can have exactly that).  But the critical point is that Google’s “other services” are methods of presenting information to consumers, just like search.  As the web and its users have evolved, and as Google has innovated to keep up with the evolving demands of consumers, it has devised or employed other means than simply providing links to a set of URLs to provide the most relevant information to its users.  The 1960s approach to antitrust condemns this as anticompetitive foreclosure; the modern version recognizes it as innovation, a form of competition that benefits consumers.

Edelman (and other critics, including a number of Senators at last month’s hearing) hearken back to the good old days and suggest that any deviation from Google’s technology or business model of the past is an indication of anticompetitive conduct:

The Google of 2004 promised to help users “leave its website as quickly as possible” while showing, initially, zero ads.  But times have changed.  Google has modified its site design to encourage users to linger on other Google properties, even when competing services have more or better information.  And Google now shows as many fourteen ads on a page.

It is hard to take seriously an argument that turns on criticizing a company simply for looking different than it did seven years ago.  Does anybody remember what search results looked like 7 years ago?  A theory of antitrust liability that would condemn a firm for investing billions of dollars in research and product development, constantly evolving its product to meet consumer demand, taking advantage of new technology, and developing its business model to increase profitability should not be taken seriously.  This is particularly true where, as here, every firm in the industry has followed a similar course, adopting the same or similar innovations.  I encourage readers to try a few queries on http://www.bing-vs-google.com/– where you can get side by side comparisons – in order to test whether the evolution of search results and innovation to meet consumer preferences is really a Google-specific thing or an industry wide phenomenon consistent with competition.  Conventional antitrust analysis holds that when conduct is engaged in not only by allegedly dominant firms, but also by every other firm in an industry, that conduct is presumptively efficient, not anticompetitive.

The main thrust of my critique is that Edelman and other Google critics rely on an outdated antitrust framework in which consumers play little or no role.  Rather than a consumer-welfare based economic critique consistent with the modern approach, these critics (as Edelman does in his opening statement) turn to a collection of anecdotes and “gotcha” statements from company executives.  It is worth correcting a few of those items here, although when we’ve reached the point where identifying a firm’s alleged abuse is a function of defining what a “confirmed” fax is, we’ve probably reached the point of decreasing marginal returns.  Rest assured that a series of (largely inaccurate) anecdotes about Google’s treatment of particular websites or insignificant contract terms is wholly insufficient to meet the standard of proof required to make a case against the company under the Sherman Act or even the looser Federal Trade Commission Act.

  • It appears to be completely inaccurate to say that “[a]n unsatisfied advertiser must complain to Google by ‘first class mail or air mail or overnight courier’ with a copy by ‘confirmed facsimile.’”  A quick search, even on Bing, leads one to this page, indicating that complaints may be submitted via web form.
  • It is likewise inaccurate to claim that “advertisers are compelled to accept whatever terms Google chooses to impose.  For example, an advertiser seeking placement through Google’s premium Search Network partners (like AOL and The New York Times) must also accept placement through the entire Google Search Network which includes all manner . . . undesirable placements.”  In actuality, Google offers a “Site and Category Exclusion Tool” that seems to permit advertisers to tailor their placements to exclude exactly these “undesirable placements.”
  • “Meanwhile, a user searching for restaurants, hotels, or other local merchants sees Google Places results with similar prominence, pushing other information services to locations users are unlikely to notice.”  I have strived in vain to enter a search for a restaurant, hotel, or the like into Google that yielded results that effectively hid “other information services” from my notice, but for some of my searches, Google Places did come up first or second (and for others it showed up further down the page).
  • Edelman has noted elsewhere that, sometimes, for some of the searches he has tested, the most popular result on Google (as well, I should add, on other, non-“dominant” sites) is not the first, Google-owned result, but instead the second.  He cites this as evidence that Google is cooking the books, favoring its own properties when users actually prefer another option.  It actually doesn’t demonstrate that, but let’s accept the claim for the sake of argument.  Notice what his example also demonstrates: that users who prefer the second result to the first are perfectly capable of finding it and clicking on it.  If this is foreclosure, Google is exceptionally bad at it.

The crux of Edelman’s complaint seems to be that Google is competing in ways that respond to consumer preferences.  This is precisely what antitrust seeks to encourage, and we would not want a set of standards that chilled competition because of a competitor’s success.  Having been remarkably successful in serving consumers’ search demands in a quickly evolving market, it would be perverse for the antitrust laws to then turn upon Google without serious evidence that it had, in fact, actually harmed consumers.

Untethered from consumer welfare analysis, antitrust threatens to re-orient itself to the days when it was used primarily as a weapon against rivals and thus imposed a costly tax on consumers.  It is perhaps telling that Microsoft, Expedia, and a few other Google competitors are the primary movers behind the effort to convict the company.  But modern antitrust, shunning its inglorious past, requires actual evidence of anticompetitive effect before condemning conduct, particularly in fast-moving, innovative industries.  Neither Edelman nor any of Google’s other critics, offer any.

During the heady days of the Microsoft antitrust case, the big question was whether modern antitrust would be able to keep up with quickly evolving markets.  The treatment of the proferred case against Google is an important test of the proposition (endorsed by the Antitrust Modernization Commission and others) that today’s antitrust is capable of consistent and coherent application in innovative, high-tech markets.  An enormous amount is at stake.  Faced with the high stakes and ever-evolving novelty of high-tech markets, antitrust will only meet this expectation if it remains grounded and focused on the core principle of competitive effects and consumer harm.  Without it, antitrust will devolve back into the laughable and anti-consumer state of affairs of the 1960s—and we will all pay for it.

ACS Blog Debate on Google: Retrograde Antitrust Analysis is No Fit for Google

Posted by Josh Wright on October 3, 2011

I am participating in an online “debate” at the American Constitution Society with Professor Ben Edelman.  The debate consists of an opening statement and concluding responses to be posted later in the week.  Professor Edelman’s opening statement is here.  I am cross-posting my opening statement here at TOTM, and will cross-post my closing statement later this week.

The theoretical antitrust case against Google reflects a troubling disconnect between the state of our technology and the state of our antitrust economics.  Google’s is a 2011 high tech market being condemned by 1960s economics.  Of primary concern (although there are a lot of things to be concerned about, and my paper with Geoffrey Manne, “If Search Neutrality Is the Answer, What’s the Question?,” canvasses the problems in much more detail) is the treatment of so-called search bias (whereby Google’s ownership and alleged preference for its own content relative to rivals’ is claimed to be anticompetitive) and the outsized importance given to complaints by competitors and individual web pages rather than consumer welfare in condemning this bias.

The recent political theater in the Senate’s hearings on Google displayed these problems prominently, with the first half of the hearing dedicated to Senators questioning Google’s Eric Schmidt about search bias and the second half dedicated to testimony from and about competitors and individual websites allegedly harmed by Google.  Very little, if any, attention was paid to the underlying economics of search technology, consumer preferences, and the ultimate impact of differentiation in search rankings upon consumers.

So what is the alleged problem?  Well, in the first place, the claim is that there is bias.  Proving that bias exists — that Google favors its own maps over MapQuest’s, for example — would be a necessary precondition for proving that the conduct causes anticompetitive harm, but let us be clear that the existence of bias alone is not sufficient to show competitive harm, nor is it even particularly interesting, at least viewed through the lens of modern antitrust economics.

In fact, economists have known for a very long time that favoring one’s own content — a form of “vertical” arrangement whereby the firm produces (and favors) both a product and one of its inputs — is generally procompetitive.  Vertically integrated firms may “bias” their own content in ways that increase output, just as other firms may do so by arrangement with others.  Economists since Nobel Laureate Ronald Coase have known — and have been reminded by Klein, Crawford & Alchian, as well as Nobel Laureate Oliver Williamson and many others — that firms may achieve by contract anything they could do within the boundaries of the firm.  The point is that, in the economics literature, it is well known that self-promotion in a vertical relationship can be either efficient or anticompetitive depending on the circumstances of the situation.  It is never presumptively problematic.  In fact, the empirical literature suggests that such relationships are almost always procompetitive and that restrictions imposed upon the abilities of firms to enter them generally reduce consumer welfare.  Procompetitive vertical integration is the rule; the rare exception (and the exception relevant to antitrust analysis) is the use of vertical arrangements to harm not just individual competitors, but competition, thus reducing consumer welfare.

One has to go back to the antitrust economics of the 1960s to find a literature — and a jurisprudence — espousing the notion that “bias” alone is inherently an antitrust problem.  This is why it is so disconcerting to find academics, politicians, and policy wags promoting such theories today on the basis that this favoritism harms competitors.  The relevant antitrust question is not whether there is bias but whether that bias is efficient.  Evidence that other search engines with much smaller market shares, and certainly without any market power, exhibit similar bias suggests that the practice certainly has some efficiency justifications.  Ignoring that possibility ignores nearly a half century of economic theory and empirical evidence.

It adds insult to injury to point to harm borne by competitors as justification for antitrust enforcement already built upon outdated, discredited economic notions.  The standard in antitrust jurisprudence (and antitrust economics) is harm to consumers.  When a monopolist restricts output and prices go up, harming consumers, it is a harm potentially cognizable by antitrust; but when Safeway brands, sells, and promotes its own products and the only identifiable harm is that Kraft sells less macaroni and cheese, it is not.

Understanding the competitive economics of vertical integration and vertical contractual arrangements is difficult because there are generally both anticompetitive and procompetitive theories of the conduct.  One must be very careful with the facts in these cases to avoid conflating harm to rivals arising from competition on the merits with harm to competition arising out of exclusionary conduct.  Misapplication of even this nuanced approach can generate significant consumer harm by prohibiting efficient, pro-consumer conduct that is wrongly determined to be the opposite and by reducing incentives for other firms to take risks and innovate for fear that they, too, will be wrongly condemned.

Professor Edelman has been prominent among Google’s critics calling for antitrust intervention.  Yet, unfortunately, he too has demonstrated a surprising inattention to this complexity and its very real anti-consumer consequences.  In an interview in Politico (login required), he suggests that we should simply prevent Google from vertically integrating:

I don’t think it’s out of the question given the complexity of what Google has built and its persistence in entering adjacent, ancillary markets.  A much simpler approach, if you like things that are simple, would be to disallow Google from entering these adjacent markets.  OK, you want to be dominant in search?  Stay out of the vertical business, stay out of content.

This sort of thinking implies that the harm suffered by competing content providers justifies preventing Google from adopting an entire class of common business relationships on the implicit assumption that competitor harm is relevant to antitrust economics and the ban on vertical integration is essentially costless.  Neither is true.  U.S. antitrust law requires a demonstration that consumers — not just rivals — will be harmed by a challenged practice.  But consumers’ interests are absent from this assessment on both sides — on the one hand by adopting harm to competitors rather than harm to consumers as a relevant antitrust standard and on the other by ignoring the hidden harm to consumers from blithely constraining potentially efficient business conduct.

Actual, measurable competitive effects are what matters for modern antitrust analysis, not presumptions about competitive consequences derived from the structure of a firm or harm to its competitors.  Unfortunately for its critics, in Google’s world, prices to consumers are zero, there is a remarkable amount of investment and innovation (not only from Google but also from competitors like Bing, Blekko, Expedia, and others), consumers are happy, and, significantly, Google is far less dominant than critics and senators suggest.  Facebook is now the most visited page on the Internet.  Many online marketers no longer view Google as the standard, but are instead increasingly looking to social media (like Facebook) as the key to advertisers’ success in attracting eyeballs on the Internet.  And at the end of the day, competition really is “just a click away” (OK, a few letters away) as Google has no control over users’ ability to employ other search engines, use other sources of information, or simply directly access content, all by typing a different URL into a browser.

Finally, even if there is a concern, there is the problem of what to do about it.  Even if Google’s critics were to demonstrate that bias is anticompetitive, it is relevant to any analysis that bias is hard to identify, that there is considerable disagreement among users over whether it is problematic in any given instance, that a remedy would be difficult to design and harder to enforce, and that the costs of being wrong are significant.

Tom Barnett — who was formerly in charge of the Antitrust Division at the DOJ and who now represents Expedia and vociferously criticizes Google (including at the Senate hearings in September) — has himself made this point, observing that:

No institution that enforces the antitrust laws is omniscient or perfect.  Among other things, antitrust enforcement agencies and courts lack perfect information about pertinent facts, including the impact of particular conduct on consumer welfare . . . . We face the risk of condemning conduct that is not harmful to competition . . . and the risk of failing to condemn conduct that does harm competition . . .

Condemning Google for developing Google Maps as a better form of search result than its original “ten blue links” reflects retrograde economics and a strange and costly preference for the status quo over innovation.  Doing so because it harms a competitor turns conventional antitrust analysis on its head with consumers bearing the cost in terms of reduced innovation and satisfaction.

FairSearch’s Non-Sequitur Response

Posted by Geoffrey Manne & Joshua Wright on July 19, 2011

Our search neutrality paper has received some recent attention.  While the initial response from Gordon Crovitz in the Wall Street Journal was favorable, critics are now voicing their responses.  Although we appreciate FairSearch’s attempt to engage with our paper’s central claims, its response is really little more than an extended non-sequitur and fails to contribute to the debate meaningfully.

Unfortunately, FairSearch grossly misstates our arguments and, in the process, basic principles of antitrust law and economics.  Accordingly, we offer a brief reply to correct a few of the most critical flaws, point out several quotes in our paper that FairSearch must have overlooked when they were characterizing our argument, and set straight FairSearch’s various economic and legal misunderstandings.

We want to begin by restating the simple claims that our paper does—and does not—make.

Our fundamental argument is that claims that search discrimination is anticompetitive are properly treated skeptically because:  (1) discrimination (that is, presenting or ranking a search engine’s own or affiliated content more prevalently than its rivals’ in response to search queries) arises from vertical integration in the search engine market (i.e., Google responds to a query by providing not only “10 blue links” but also perhaps a map or video created Google or previously organized on a Google-affiliated site (YouTube, e.g.)); (2) both economic theory and evidence demonstrate that such integration is generally pro-competitive; and (3) in Google’s particular market, evidence of intense competition and constant innovation abounds, while evidence of harm to consumers is entirely absent.  In other words, it is much more likely than not that search discrimination is pro-competitive rather than anticompetitive, and doctrinal error cost concerns accordingly counsel great hesitation in any antitrust intervention, administrative or judicial.  As we will discuss, these are claims that FairSearch’s lawyers are quite familiar with.

FairSearch, however, grossly mischaracterizes these basic points, asserting instead that we claim

 “that even if Google does [manipulate its search results], this should be immune from antitrust enforcement due to the difficulty of identifying ‘bias’ and the risks of regulating benign conduct.”

This statement is either intentionally deceptive or betrays a shocking misunderstanding of our central claim for at least two reasons: (1) we never advocate for complete antitrust immunity, and (2) it trivializes the very real—and universally-accepted–difficulty of distinguishing between pro- and anticompetitive conduct.

First, we acknowledge the obvious point that as a theoretical matter discrimination can amount to an antitrust violation in some cases under certain specific circumstances—not the least important of which is proof of actual competitive harm.  To quote ourselves:

The key question is whether such a bias benefits consumers or inflicts competitive harm.  Economic theory has long understood the competitive benefits of such vertical integration; modern economic theory also teaches that, under some conditions, vertical integration and contractual arrangements can create a potential for competitive harm that must be weighed against those benefits . . . .  From a policy perspective, the issue is whether some sort of ex ante blanket prohibition or restriction on vertical integration is appropriate instead of an ex post, fact-intensive evaluation on a case-by-case basis, such as under antitrust law. (Manne and Wright, 2011) (emphasis added).

This is not much of a concession.  While FairSearch tries to move the goalposts by focusing on a straw man proposition that search bias is categorically immune from antitrust scrutiny, this sleight of hand doesn’t accomplish much and reveals what FairSearch is missing.   After all, consider that almost every single form of business conduct can be an antitrust violation under some set of conditions!  The antitrust laws apply in principle to (that is, do not categorically make immune) horizontal mergers, vertical mergers, long-term contracts, short-term contracts, exclusive dealing, partial exclusive dealing, burning down a rival’s factory, dealing with rivals, refusing to dealing with rivals, boycotts, tying contracts, overlapping boards, and all manner of pricing practices.  Indeed, it is hard to find categories of business conduct that are outright immune from the antitrust laws.  So—we agree:  “Search bias” can conceivably be anticompetitive.  Unfortunately for FairSearch, we never said otherwise and it’s not a very interesting point to discuss.

With that point firmly established, one can return focus to the topic FairSearch painstakingly avoids throughout its response and on which we think the issue really does (and should) turn: Where’s the proof of consumer harm?

Searching for Antitrust Remedies, Part II

Posted by Josh Wright on July 13, 2011

In the last post, I discussed possible characterizations of Google’s conduct for purposes of antitrust analysis.  A firm grasp of the economic implications of the different conceptualizations of Google’s conduct is a necessary – but not sufficient – precondition for appreciating the inconsistencies underlying the proposed remedies for Google’s alleged competitive harms.  In this post, I want to turn to a different question: assuming arguendo a competitive problem associated with Google’s algorithmic rankings – an assumption I do not think is warranted, supported by the evidence, or even consistent with the relevant literature on vertical contractual relationships – how might antitrust enforcers conceive of an appropriate and consumer-welfare-conscious remedy?  Antitrust agencies, economists, and competition policy scholars have all appropriately stressed the importance of considering a potential remedy prior to, rather than following, an antitrust investigation; this is good advice not only because of the benefits of thinking rigorously and realistically about remedial design, but also because clear thinking about remedies upfront might illuminate something about the competitive nature of the conduct at issue.

Somewhat ironically, former DOJ Antitrust Division Assistant Attorney General Tom Barnett – now counsel for Expedia, one of the most prominent would-be antitrust plaintiffs against Google – warned (in his prior, rather than his present, role) that “[i]mplementing a remedy that is too broad runs the risk of distorting markets, impairing competition, and prohibiting perfectly legal and efficient conduct,” and that “forcing a firm to share the benefits of its investments and relieving its rivals of the incentive to develop comparable assets of their own, access remedies can reduce the competitive vitality of an industry.”  Barnett also noted that “[t]here seems to be consensus that we should prohibit unilateral conduct only where it is demonstrated through rigorous economic analysis to harm competition and thereby harm consumer welfare.”  Well said.  With these warnings well in-hand, we must turn to two inter-related concerns necessary to appreciating the potential consequences of a remedy for Google’s conduct: (1) the menu of potential remedies available for an antitrust suit against Google, and (2) the efficacy of these potential remedies from a consumer-welfare, rather than firm-welfare, perspective.

What are the potential remedies?

The burgeoning search neutrality crowd presents no lack of proposed remedies; indeed, if there is one segment in which Google’s critics have proven themselves prolific, it is in their constant ingenuity conceiving ways to bring governmental intervention to bear upon Google.  Professor Ben Edelman has usefully aggregated and discussed several of the alternatives, four of which bear mention:  (1) a la Frank Pasquale and Oren Bracha, the creation of a “Federal Search Commission,” (2) a la the regulations surrounding the Customer Reservation Systems (CRS) in the 1990s, a prohibition on rankings that order listings “us[ing] any factors directly or indirectly relating to” whether the search engine is affiliated with the link, (3) mandatory disclosure of all manual adjustments to algorithmic search, and (4) transfer of the “browser choice” menu of the EC Microsoft litigation to the Google search context, requiring Google to offer users a choice of five or so rivals whenever a user enters particular queries.

Geoff and I discuss several of these potential remedies in our paper, If Search Neutrality is the Answer, What’s the Question?  It suffices to say that we find significant consumer welfare threats from the creation of a new regulatory agency designed to impose “neutral” search results.  For now, I prefer to focus on the second of these remedies – analogized to CRS technology in the 1990s – here; Professor Edelman not only explains proposed CRS-inspired regulation, but does so in effusive terms:

A first insight comes from recognizing that regulators have already – successfully! – addressed the problem of bias in information services. One key area of intervention was customer reservation systems (CRS’s), the computer networks that let travel agents see flight availability and pricing for various major airlines. Three decades ago, when CRS’s were largely owned by the various airlines, some airlines favored their own flights. For example, when a travel agent searched for flights through Apollo, a CRS then owned by United Airlines, United flights would come up first – even if other carriers offered lower prices or nonstop service. The Department of Justice intervened, culminating in rules prohibiting any CRS owned by an airline from ordering listings “us[ing] any factors directly or indirectly relating to carrier identity” (14 CFR 255.4). Certainly one could argue that these rules were an undue intrusion: A travel agent was always free to find a different CRS, and further additional searches could have uncovered alternative flights. Yet most travel agents hesitated to switch CRS’s, and extra searches would be both time-consuming and error-prone. Prohibiting biased listings was the better approach.

The same principle applies in the context of web search. On this theory, Google ought not rank results by any metric that distinctively favors Google. I credit that web search considers myriad web sites – far more than the number of airlines, flights, or fares. And I credit that web search considers more attributes of each web page – not just airfare price, transit time, and number of stops. But these differences only grant a search engine more room to innovate. These differences don’t change the underlying reasoning, so compelling in the CRS context, that a system provider must not design its rules to systematically put itself first.

The analogy is a superficially attractive one, and we’re tempted to entertain it, so far as it goes.  Organizational questions inhere in both settings, and similarly so: both flights and search results must be ordinally ranked, and before CRS regulation, a host airline’s flights often appeared before those of rival airlines.  Indeed, we will take Edelman’s analogy at face value.  Problematically for Professor Edelman and others pushing the CRS-style remedy, a fuller exploration of CRS regulation reveals this market intervention – well, put simply, wasn’t so successful after all.  Not for consumers anyway.  It did, however, generate (economically) predictable consequences: reduced consumer welfare through reduced innovation. Let’s explore the consequences of Edelman’s analogy further below the fold.
