Antitrust And Platform Monopoly, Herbert J. Hovenkamp

All Faculty Scholarship

Are large digital platforms that deal directly with consumers “winner take all,” or natural monopoly, firms? That question is surprisingly complex and does not produce the same answer for every platform. The closer one looks at digital platforms the less they seem to be winner-take-all. As a result, competition can be made to work in most of them. Further, antitrust enforcement, with its accommodation of firm variety, is generally superior to any form of statutory regulation that generalizes over large numbers.

Assuming that an antitrust violation is found, what should be the remedy? Breaking up large firms subject to extensive …

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 …

Horizontal Shareholding And Antitrust Policy, Fiona M. Scott Morton, Herbert J. Hovenkamp

All Faculty Scholarship

“Horizontal shareholding” occurs when one or more equity funds own shares of competitors operating in a concentrated product market. For example, the four largest mutual fund companies might be large shareholders of all the major United States air carriers. A growing body of empirical literature concludes that under these conditions market output in the product market is lower and prices higher than they would otherwise be.

Here we consider how the antitrust laws might be applied to this practice, identifying the issues that courts are likely to encounter and attempting to anticipate litigation problems. We assume that neither the mutual …

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 …

Progressive Legal Thought, Herbert J. Hovenkamp

All Faculty Scholarship

A widely accepted model of American legal history is that "classical" legal thought, which dominated much of the nineteenth century, was displaced by "progressive" legal thought, which survived through the New Deal and in some form to this day. Within its domain, this was a revolution nearly on a par with Copernicus or Newton. This paradigm has been adopted by both progressive liberals who defend this revolution and by classical liberals who lament it.

Classical legal thought is generally identified with efforts to systematize legal rules along lines that had become familiar in the natural sciences. This methodology involved not …

Antitrust’S State Action Doctrine And The Ordinary Powers Of Corporations, Herbert J. Hovenkamp

All Faculty Scholarship

The Supreme Court has now agreed to review the Eleventh Circuit's decision in Phoebe-Putney, which held that a state statute permitting a hospital authority to acquire hospitals implicitly authorized such acquisitions when they were anticompetitive – in this particular case very likely facilitating a merger to monopoly. Under antitrust law’s “state action” doctrine a state may in fact authorize such an acquisition, provided that it “clearly articulates” its desire to approve an action that would otherwise constitute an antitrust violation and also “actively supervises” any private conduct that might fall under the state’s regulatory scheme.

“Authorization” in the context of …

Markets In Merger Analysis, Herbert J. Hovenkamp

All Faculty Scholarship

Antitrust merger policy suffers from a disconnect between its articulated concerns and the methodologies it employs. The Supreme Court has largely abandoned the field of horizontal merger analysis, leaving us with ancient decisions that have never been overruled but whose fundamental approach has been ignored or discredited. As a result the case law reflects the structuralism of a bygone era, focusing on industrial concentration and market shares, largely to the exclusion of other measures of competitive harm, including price increases. Only within the last generation has econometrics developed useful techniques for estimating the price impact of specific mergers in differentiated …

Mergers, Market Dominance And The Lundbeck Case, Herbert J. Hovenkamp

All Faculty Scholarship

In Lundbeck the Eighth Circuit affirmed a district court’s judgment that a merger involving the only two drugs approved for treating a serious heart condition in infants was lawful. Although the drugs treated the same condition they were not bioequivalents. The Eighth Circuit approved the district court’s conclusion that they had not been shown to be in the same relevant market.

Most mergers that are subject to challenge under the antitrust laws occur in markets that exhibit some degree of product differentiation. The Lundbeck case illustrates some of the problems that can arise when courts apply ideas derived from models …

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 …

Mergers And Market Dominance, Herbert J. Hovenkamp

All Faculty Scholarship

Mergers involving dominant firms legitimately receive close scrutiny under the antitrust laws, even if they involve tiny firms. Further, they should be examined closely even in markets that generally exhibit low entry barriers. Many of the so-called "unilateral effects" cases in current merger law are in fact mergers that create dominant firms. The rhetoric of unilateral effects often serves to disguise this fact by presenting the situation as if it involves the ability of a small number of firms (typically two or three) in a much larger market to increase their price to unacceptable levels. In fact, if such a …
