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 …

The Case For Preemptive Oligopoly Regulation, Jeffrey D. Manns

Indiana Law Journal

One of the few things former President Donald Trump and leading Democrats appear to agree on is the need to subject Big Technology (“Big Tech”) firms to antitrust scrutiny. But unsurprisingly they disagree about how to address the problem. Senator Elizabeth Warren and many other leading Democrats have called for breaking up large technology firms, such as Google, Amazon, and Facebook, in a revival of the trust-busting progressive era of the early twentieth century. In contrast, the Trump administration triggered more traditional antitrust monopoly review of potential anticompetitive activities of a number of leading technology firms, which is more likely …

Vertical Mergers In A Model Of Upstream Monopoly And Incomplete Information, Serge Moresi, David Reitman, Steven C. Salop, Yianis Sarafidis

Georgetown Law Faculty Publications and Other Works

We examine the role of private information on the impact of vertical mergers. A vertical merger can improve the information that is available to an upstream monopolist because, after the merger, the monopolist can observe the cost of its downstream merger partner. In the pre-merger world, because the costs of the downstream firms are private information, the monopolist has incomplete information and cannot implement the monopoly outcome: The expected pre-merger equilibrium price of the downstream product is lower than the monopoly price. After a vertical merger, the equilibrium input price that is charged to the downstream rival can either increase …

Common Ownership: Do Managers Really Compete Less?, Merritt B. Fox, Manesh S. Patel

Faculty Scholarship

This Article addresses an important question in modern antitrust: when large investment funds have holdings across an industry, is competition depressed?

The question of the impact of common ownership on competition has gained much attention as the role of institutional shareholding has grown, with the funds of the three largest management companies holding in aggregate approximately 21% of the shares of a typical S&P 500 firm. It is a source of acute disagreement among scholars and policymakers, with some who believe common ownership does depress competition seeking antitrust law reforms that would significantly constrain how investment funds operate. Neglected in …
