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 …

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 …

The Looming Crisis In Antitrust Economics, Herbert J. Hovenkamp

All Faculty Scholarship

As in so many areas of law and politics in the United States, antitrust’s center is at bay. It is besieged by a right wing that wants to limit antitrust even more than it has been limited over the last quarter century. On the left, it faces revisionists who propose significantly greater enforcement.

One thing the two extremes share, however, is denigration of the role of economics in antitrust analysis. On the right, the Supreme Court’s two most recent antitrust decisions at this writing reveal that economic analysis no longer occupies the central role that it once had. On the …

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 …

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 …

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 …

Whatever Did Happen To The Antitrust Movement?, Herbert J. Hovenkamp

All Faculty Scholarship

Antitrust in the United States today is caught between its pursuit of technical rules designed to define and implement defensible economic goals, and increasing calls for a new antitrust “movement.” The goals of this movement have been variously defined as combating industrial concentration, limiting the economic or political power of large firms, correcting the maldistribution of wealth, control of high profits, increasing wages, or protection of small business. High output and low consumer prices are typically unmentioned.

In the 1960s the great policy historian Richard Hofstadter lamented the passing of the antitrust “movement” as one of the “faded passions of …

Horizontal Mergers, Market Structure, And Burdens Of Proof, Herbert J. Hovenkamp, Carl Shapiro

All Faculty Scholarship

Since the Supreme Court’s landmark 1963 decision in Philadelphia National Bank, antitrust challengers have mounted prima facie cases against horizontal mergers that rested on the level and increase in market concentration caused by the merger, with proponents of the merger then permitted to rebut by providing evidence that the merger will not have the feared anticompetitive effects. Although the way that concentration is measured and the triggering levels have changed over the last half century, the basic approach has remained intact. This longstanding structural presumption, which is well supported by economic theory and evidence, has been critical to effective …

Antitrust Policy And Inequality Of Wealth, Herbert J. Hovenkamp

All Faculty Scholarship

Why would anyone want to use antitrust law as a wealth distribution device when far more explicit statutory tools are available for that purpose? One feature of antitrust is its open-textured, nonspecific statutes that are interpreted by judges. As a result, using antitrust to redistribute wealth may be a way of invoking the judicial process without having to go to Congress or a state legislature that is likely to be unsympathetic. Of course, a corollary is that someone attempting to use antitrust law to redistribute wealth will have to rely on the existing antitrust statutes rather than obtaining a new …

Tying Arrangements, Erik Hovenkamp, Herbert J. Hovenkamp

All Faculty Scholarship

This paper provides an overview of the law and the antitrust economics of tying. After describing the many varieties of tying arrangements we examine specific legal tying doctrines and gauge their effectiveness in identifying anticompetitive ties. We generally assume that the appropriate antitrust goal is consumer welfare; however, all situations in which consumer welfare is increased by a tie also result in an increase in general welfare. We look at the use of ties as quality control devices and as ways of obtaining both production and distribution efficiencies.

Market power in either the tying or tied product is a necessary …

Implementing Antitrust's Welfare Goals, Herbert J. Hovenkamp

All Faculty Scholarship

United States antitrust policy is said to promote some version of economic welfare. 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. One important welfare debate is whether antitrust should adopt a “consumer welfare” principle rather than a more general “total welfare” principle.

The simple version of the consumer welfare test is not a balancing test. If consumers are harmed by reduced output or higher prices resulting from the exercise of market power, …

Consumer Welfare In Competition And Intellectual Property Law, Herbert J. Hovenkamp

All Faculty Scholarship

Whether antitrust policy should pursue a goal of "general welfare" or "consumer welfare" has been debated for decades. The academic debate is much more varied than the case law, however, which has consistently adopted consumer welfare as a goal, almost never condemning a practice found to produce an actual output reduction or price increase simply because productive efficiency gains accruing to producers exceeded consumer losses.

While some practices such as mergers might produce greater gains in productive efficiency than losses in consumer welfare, identifying such situations would be extraordinarily difficult. First, these efficiencies would have to be "transaction specific," meaning …
