Selling Antitrust, Herbert J. Hovenkamp

All Faculty Scholarship

Antitrust enforcers and its other defenders have never done a good job of selling their field to the public. That is not entirely their fault. Antitrust is inherently technical, and a less engaging discipline to most people than, say, civil rights or criminal law. The more serious problem is that when the general press does talk about antitrust policy it naturally gravitates toward the fringes, both the far right and the far left. Extreme rhetoric makes for better press than the day-to-day operations of a technical enterprise. The extremes are often stated in overdramatized black-and-white terms that avoid the real …

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 With one exception, however, the statute reads so broadly that criticisms of the nature that it is outdated cannot be based on faithful readings of the text.

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 …

The Invention Of Antitrust, Herbert J. Hovenkamp

All Faculty Scholarship

The long Progressive Era, from 1900 to 1930, was the Golden Age of antitrust theory, if not of enforcement. During that period courts and Progressive scholars developed nearly all of the tools that we use to this day to assess anticompetitive practices under the federal antitrust laws. In a very real sense we can say that this group of people invented antitrust law. The principal contributions the Progressives made to antitrust policy were (1) partial equilibrium analysis, which became the basis for concerns about economic concentration, the distinction between short- and long-run analysis, and later provided the foundation for the …
