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 …

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 …

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 …
