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 …

Tech, Regulatory Arbitrage, And Limits, Elizabeth Pollman

All Faculty Scholarship

Regulatory arbitrage refers to structuring activity to take advantage of gaps or differences in regulations or laws. Examples include Facebook modifying its terms and conditions to reduce the exposure of its user data to strict European privacy laws, and Uber and other platform companies organizing their affairs to categorize workers as non-employees. This essay explores the constraints and limits on regulatory arbitrage through the lens of the technology industry, known for its adaptiveness and access to strategic resources. Specifically, the essay explores social license and the bundling of laws and resources as constraining forces on regulatory arbitrage, and the legal …

Framing A Purpose For Corporate Law, William W. Bratton

All Faculty Scholarship

This article seeks to frame a short statement of purpose for corporate law on which all reasonable observers can agree. The statement, in order to succeed at its intended purpose, must satisfy two strict conditions: first, it must have enough content to be meaningful; second, it must be completely uncontroversial, both descriptively and normatively. The exercise, thus described, involves avoiding the issues that occupy center stage in discussions about corporate law while at the same time highlighting the discussants’ generally held presuppositions. Three closely interconnected issues arise. First, whether the statement of the purpose of corporate law should speak in …

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 …
