The Slogans And Goals Of Antitrust Law, Herbert J. Hovenkamp

All Faculty Scholarship

This is a comparative examination of the slogans and goals most advocated for antitrust law today – namely, that antitrust should be concerned with “bigness,” that it should intervene when actions undermine the “competitive process,” or that it should be concerned about promoting some conception of welfare. “Bigness” as an antitrust concern targets firms based on absolute size rather than share of a market, as antitrust traditionally has done. The bigness approach entails that antitrust cannot be concerned about low prices, or the welfare of consumers and labor. Nondominant firms could not sustain very high prices or cause significant reductions …

Worker Welfare And Antitrust, Herbert J. Hovenkamp

All Faculty Scholarship

The important field of antitrust and labor has gone through a profound change in orientation. For the great bulk of its history labor has been viewed as a competitive threat, and the debate over antitrust and labor was framed around whether there should be a labor “immunity” from the antitrust laws. In just the last decade, however, the orientation has flipped. Most new writing views labor as a target of anticompetitive restraints imposed by employers. Antitrust is increasingly concerned with protecting labor rather than challenging its conduct.

Antitrust interest in labor markets is properly focused on two things. The smaller …

The Progressives' Antitrust Toolbox, Herbert J. Hovenkamp

All Faculty Scholarship

The period 1900 to 1930 was the Golden Age of antitrust theory, if not of enforcement. During that period courts and scholars developed nearly all of the tools that we use to this day to assess anticompetitive practices under the federal antitrust laws. In subsequent years antitrust policy veered to both the left and the right, but today seems to be returning to a position quite similar to the one that these Progressive adopted. Their principal contributions were (1) partial equilibrium analysis, which became the basis for concerns about economic concentration, the distinction between short- and long-run analysis, and later …

Monopolizing Digital Commerce, Herbert J. Hovenkamp

All Faculty Scholarship

Section 2 of the Sherman Act condemns firms who “monopolize,” “attempt to monopolize,” or “combine or conspire” to monopolize—all without explanation. Section 2 is the antitrust law’s only provision that reaches entirely unilateral conduct, although it has often been used to reach collaborative conduct as well. In general, § 2 requires greater amounts of individually held market power than do the other antitrust statutes, but it is less categorical about conduct. With one exception, however, the statute reads so broadly that criticisms of the nature that it is outdated cannot be based on faithful readings of the text.

The one …

Antitrust Error Costs, Herbert J. Hovenkamp

All Faculty Scholarship

The idea that consideration of error costs should inform judgments about actions with uncertain consequences is well established. When we act on imperfect information, we consider not only the probability of an event, but also the expected costs of making an error. In 1984 Frank Easterbrook used this idea to rationalize an anti-enforcement bias in antitrust, reasoning that markets are likely to correct monopoly in a relatively short time while judicial errors are likely to persist. As a result, false positives (recognizing a problem when there is none) are more costly than false negatives. While the problem of error cost …

Antitrust Harm And Causation, Herbert J. Hovenkamp

All Faculty Scholarship

How should plaintiffs show harm from antitrust violations? The inquiry naturally breaks into two issues: first, what is the nature of the harm? and second, what does proof of causation require? The best criterion for assessing harm is likely or reasonably anticipated output effects. Antitrust’s goal should be output as high as is consistent with sustainable competition.

The standard for proof of causation then depends on two things: the identity of the enforcer and the remedy that the plaintiff is seeking. It does not necessarily depend on which antitrust statute the plaintiff is seeking to enforce. For public agencies, enforcement …

Is The Digital Economy Too Concentrated?, Jonathan Klick

All Faculty Scholarship

Concentration in the digital economy in the United States has sparked loud criticism and spurred calls for wide-ranging reforms. These reforms include everything from increased enforcement of existing antitrust laws, such as challenging more mergers and breaking up firms, to an abandonment of the consumer welfare standard. Critics cite corruption and more systemic public choice problems, while others invoke the populist origins of antitrust to slay the digital Goliaths. On the other side, there is skepticism regarding these arguments. This chapter continues much of that skepticism.

Network Effects In Action, Christopher S. Yoo

All Faculty Scholarship

This Chapter begins by examining and exploring the theoretical and empirical limits of the possible bases of network effects, paying particular attention to the most commonly cited framework known as Metcalfe’s Law. It continues by exploring the concept of network externalities, defined as the positive external consumption benefits that the decision to join a network creates for the other members of the network, which is more ambiguous than commonly realized. It then reviews the structural factors needed for models based on network effects to have anticompetitive effects and identifies other factors that can dissipate those effects. Finally, it identifies alternative …

Competitive Harm From Vertical Mergers, Herbert J. Hovenkamp

All Faculty Scholarship

The antitrust enforcement Agencies' 2020 Vertical Merger Guidelines introduce a nontechnical application of bargaining theory into the assessment of competitive effects from vertical acquisitions. The economics of such bargaining is complex and can produce skepticism among judges, who might regard its mathematics as overly technical, its game theory as excessively theoretical or speculative, or its assumptions as unrealistic.

However, we have been there before. The introduction of concentration indexes, particularly the HHI, in the Merger Guidelines was initially met with skepticism but gradually they were accepted as judges became more comfortable with them. The same thing very largely happened again …

Antitrust: What Counts As Consumer Welfare?, Herbert J. Hovenkamp

All Faculty Scholarship

Antitrust’s consumer welfare principle is accepted in some form by the entire Supreme Court and the majority of other writers. However, it means different things to different people. For example, some members of the Supreme Court can simultaneously acknowledge the antitrust consumer welfare principle even as they approve practices that result in immediate, obvious, and substantial consumer harm. At the same time, however, a properly defined consumer welfare principle is essential if antitrust is to achieve its statutory purpose, which is to pursue practices that injure competition. The wish to make antitrust a more general social justice statute is understandable: …

On The Meaning Of Antitrust's Consumer Welfare Principle, Herbert J. Hovenkamp

All Faculty Scholarship

This brief essay addresses the ambiguities in the meaning of “consumer welfare” in antitrust, exploring the differences between the Williamson, Bork, and current understanding of that term. After weighing the alternatives it argues that the consumer welfare principle in antitrust should seek out that state of affairs in which output is maximized, consistent with sustainable competition

The Post-Chicago Antitrust Revolution: A Retrospective, Christopher S. Yoo

All Faculty Scholarship

A symposium examining the contributions of the post-Chicago School provides an appropriate opportunity to offer some thoughts on both the past and the future of antitrust. This afterword reviews the excellent papers with an eye toward appreciating the contributions and limitations of both the Chicago School, in terms of promoting the consumer welfare standard and embracing price theory as the preferred mode of economic analysis, and the post-Chicago School, with its emphasis on game theory and firm-level strategic conduct. It then explores two emerging trends, specifically neo-Brandeisian advocacy for abandoning consumer welfare as the sole goal of antitrust and the …

What’S In Your Wallet (And What Should The Law Do About It?), Natasha Sarin

All Faculty Scholarship

In traditional markets, firms can charge prices that are significantly elevated relative to their costs only if there is a market failure. However, this is not true in a two-sided market (like Amazon, Uber, and Mastercard), where firms often subsidize one side of the market and generate revenue from the other. This means consideration of one side of the market in isolation is problematic. The Court embraced this view in Ohio v. American Express, requiring that anticompetitive harm on one side of a two-sided market be weighed against benefits on the other side.

Legal scholars denounce this decision, which, …

Framing The Chicago School Of Antitrust Analysis, Herbert J. Hovenkamp, Fiona Scott Morton

All Faculty Scholarship

The Chicago School of antitrust has benefited from a great deal of law office history, written by admiring advocates rather than more dispassionate observers. This essay attempts a more neutral stance, looking at the ideology, political impulses, and economics that produced the Chicago School of antitrust policy and that account for its durability.

The origins of the Chicago School lie in a strong commitment to libertarianism and nonintervention. Economic models of perfect competition best suited these goals. The early strength of the Chicago School of antitrust was that it provided simple, convincing answers to everything that was wrong with antitrust …

Is Antitrust's Consumer Welfare Principle Imperiled?, Herbert J. Hovenkamp

All Faculty Scholarship

Antitrust’s consumer welfare principle stands for the proposition that antitrust policy should encourage markets to produce output as high as is consistent with sustainable competition, and prices that are accordingly as low. Such a policy does not protect every interest group. For example, it opposes the interests of cartels or other competition-limiting associations who profit from lower output and higher prices. It also runs counter to the interest of less competitive firms that need higher prices in order to survive. Market structure is relevant to antitrust policy, but its importance is contingent rather than absolute – that is, market structure …

Prophylactic Merger Policy, Herbert J. Hovenkamp

All Faculty Scholarship

An important purpose of the antitrust merger law is to arrest certain anticompetitive practices or outcomes in their “incipiency.” Many Clayton Act decisions involving both mergers and other practices had recognized the idea as early as the 1920s. In Brown Shoe the Supreme Court doubled down on the idea, attributing to Congress a concern about a “rising tide of economic concentration” that must be halted “at its outset and before it gathered momentum.” The Supreme Court did not explain why an incipiency test was needed to address this particular problem. Once structural thresholds for identifying problematic mergers are identified there …

Hipster Antitrust: New Bottles, Same Old W(H)Ine?, Christopher S. Yoo

All Faculty Scholarship

Although the debate over hipster antitrust is often portrayed as something new, experienced observers recognize it as a replay of an old argument that was resolved by the global consensus that antitrust should focus on consumer welfare rather than on the size of firms, the levels of industry concentration, and other considerations. Moreover, the history of the Federal Trade Commission’s Section 5 authority to prevent unfair methods of competition stands as a reminder of the dangers of allowing enforcement policy to be guided by vague and uncertain standards.

Appraising Merger Efficiencies, Herbert J. Hovenkamp

All Faculty Scholarship

Mergers of business firms violate the antitrust laws when they threaten to lessen competition, which generally refers to a price increase resulting from a reduction in output. However, a merger that threatens competition may also enable the post-merger firm to reduce its costs or improve its product. Attitudes toward mergers are heavily driven by assumptions about efficiency gains. If mergers of competitors never produced efficiency gains but simply reduced the number of competitors, a strong presumption against them would be warranted. We tolerate most mergers because of a background, highly generalized belief that most or at least many produce cost …

Antitrust Balancing, Herbert J. Hovenkamp

All Faculty Scholarship

Antitrust litigation often confronts situations where effects point in both directions. Judges sometimes describe the process of evaluating these factors as “balancing.” In its e-Books decision the Second Circuit believed that the need to balance is what justifies application of the rule of reason. In Microsoft the D.C. Circuit stated that “courts routinely apply a…balancing approach” under which “the plaintiff must demonstrate that the anticompetitive harm…outweighs the procompetitive benefit.” But then it decided the case without balancing anything.

The term “balancing” is a very poor label for what courts actually do in these cases. Balancing requires that two offsetting effects …

Re-Imagining Antitrust: The Revisionist Work Of Richard S. Markovits, Herbert J. Hovenkamp

All Faculty Scholarship

This review discusses Richard Markovits’ two volume book "Economics and the Interpretation" and "Application of U.S. and E.U. Antitrust Law" (2014), focusing mainly on Markovits’ approaches to antitrust tests of illegality, pricing offenses, market definition and the assessment of market power, and his important work anticipating unilateral effects theory in merger cases. Markovits argues forcefully that the Sherman and Clayton Acts were intended to employ different tests of illegality. As a result, even when they cover the same practices, such as mergers, exclusive dealing, or tying, they address them under different tests. He then shows how he would analyze various …

Antitrust And The Close Look: Transaction Cost Economics In Competition Policy, Herbert J. Hovenkamp

All Faculty Scholarship

This paper briefly examines the contributions of Transaction Cost Economics (TCE) to antitrust analysis, focusing on vertical integration and its contractual substitutes, mainly, minimum and maximum resale price maintenance, vertical nonprice restraints, tying, bundled discounts and exclusive dealing and related exclusionary contracts.

TCE generally assumes that business firms organize their activities so as to maximize their value, which they can do both by economizing and also by obtaining higher prices. Sensible antitrust policy recognizes that both advantageous contracting and monopoly can be profitable to a firm, and it can be expected to pursue both when they are available. Nevertheless, the …

Distributive Justice And Consumer Welfare In Antitrust, Herbert J. Hovenkamp

All Faculty Scholarship

The dominant view of antitrust policy in the United States is that it is intended to promote some version of economic welfare. More specifically, antitrust promotes allocative efficiency by ensuring that markets are as competitive as they can practicably be, and that firms do not face unreasonable roadblocks to attaining productive efficiency, which refers to both cost minimization and innovation.

The distribution concern that has dominated debates over United States antitrust policy over the last several decades is whether antitrust should adopt a “consumer welfare” principle rather than a more general neoclassical “total welfare” principle. In The Antitrust Paradox Robert …

Antitrust And The Costs Of Movement, Herbert J. Hovenkamp

All Faculty Scholarship

Antitrust is rightfully concerned about the structure of markets as well as the bargaining that occurs in them. As a result, the absolute cost of redeploying resources can be just as important as the transaction costs of arranging for their movement. This paper examines several broad themes in antitrust, considering the role of various assumptions about the costs of getting resources moved toward superior positions and the ability of the antitrust system to facilitate this movement. Part II very briefly examines structuralism as a theory underlying antitrust enforcement, particularly its assumptions about the difficulty and costs of moving resources. Harvard …

A Preface To Neoclassical Legal Thought, Herbert J. Hovenkamp

All Faculty Scholarship

Most legal historians speak of the period following classical legal thought as “progressive legal thought.” That term creates an unwarranted bias in characterization, however, creating the impression that conservatives clung to an obsolete “classical” ideology, when in fact they were in many ways just as revisionist as the progressives legal thinkers whom they critiqued. The Progressives and New Deal thinkers whom we identify with progressive legal thought were nearly all neoclassical, or marginalist, in their economics, but it is hardly true that all marginalists were progressives. For example, the lawyers and policy makers in the corporate finance battles of the …

A Primer On Antitrust Damages, Herbert J. Hovenkamp

All Faculty Scholarship

This paper considers the theory of antitrust damages and then discusses some simple models for proving them. Antitrust damages theory begins with the premise that many practices alleged to violate the antitrust laws cause no consumer harm. Others are inefficient and have few socially redeeming virtues. Still others may simultaneously increase both the efficiency of the participants and their market power. A perfectly designed antitrust policy would exonerate the first set of practices, condemn the second set, and condemn the third set only when the social cost of the restraint exceeds its social value or they produce net harm to …

The Law Of Vertical Integration And The Business Firm: 1880-1960, Herbert J. Hovenkamp

All Faculty Scholarship

Vertical integration occurs when a firm does something for itself that it could otherwise procure on the market. For example, a manufacturer that opens its own stores is said to be vertically integrated into distribution. One irony of history is that both classical political economy and neoclassicism saw vertical integration and vertical contractual arrangements as much less threatening to competition than cartels or other horizontal arrangements. Nevertheless, vertical integration has produced by far the greater amount of legislation at both federal and state levels and has motivated many more political action groups. Two things explain this phenomenon. First, while economists …

Harvard, Chicago And Transaction Cost Economics In Antitrust Analysis, Herbert J. Hovenkamp

All Faculty Scholarship

Since Oliver Williamson published Markets and Hierarchies in 1975 transaction cost economics (TCE) has claimed an important place in antitrust, avoiding the extreme positions of the two once reigning schools of antitrust policy. At one extreme was the “structural” school, which saw market structure as the principal determinant of poor economic performance. At the other extreme was the Chicago School, which also saw the economic landscape in terms of competition and monopoly, but found monopoly only infrequently and denied that a monopolist could “leverage” its power into related markets. Since the 1970s both the structural and Chicago positions have moved …

The Neal Report And The Crisis In Antitrust, Herbert J. Hovenkamp

All Faculty Scholarship

The Neal Report, which was commissioned by Lyndon Johnson and published in 1967, is rightfully criticized for representing the past rather than the future of antitrust. Its authors completely embraced a theory of competition and industrial organization that had dominated American economic thinking for forty years, but was just in the process of coming to an end. The structure-conduct-performance (S-C-P) paradigm that the Neal Report embodied had in fact been one of the most elegant and most tested theories of industrial organization. The theory represented the high point of structuralism in industrial organization economics, resting on the proposition that certain …
