Digital Cluster Markets, Herbert J. Hovenkamp Apr 2022

Digital Cluster Markets, Herbert J. Hovenkamp

All Faculty Scholarship

This paper considers the role of “cluster” markets in antitrust litigation, the minimum requirements for recognizing such markets, and the relevance of network effects in identifying them.

One foundational requirement of markets in antitrust cases is that they consist of products that are very close substitutes for one another. Even though markets are nearly always porous, this principle is very robust in antitrust analysis and there are few deviations.

Nevertheless, clustering noncompeting products into a single market for purposes of antitrust analysis can be valuable, provided that its limitations are understood. Clustering contributes to market power when (1) many customers …


Regulating New Tech: Problems, Pathways, And People, Cary Coglianese Dec 2021

Regulating New Tech: Problems, Pathways, And People, Cary Coglianese

All Faculty Scholarship

New technologies bring with them many promises, but also a series of new problems. Even though these problems are new, they are not unlike the types of problems that regulators have long addressed in other contexts. The lessons from regulation in the past can thus guide regulatory efforts today. Regulators must focus on understanding the problems they seek to address and the causal pathways that lead to these problems. Then they must undertake efforts to shape the behavior of those in industry so that private sector managers focus on their technologies’ problems and take actions to interrupt the causal pathways. …

Due Process In Antitrust Enforcement: Normative And Comparative Perspectives, Christopher S. Yoo, Yong Huang, Thomas Fetzer, Shan Jiang Jan 2021

Due Process In Antitrust Enforcement: Normative And Comparative Perspectives, Christopher S. Yoo, Yong Huang, Thomas Fetzer, Shan Jiang

All Faculty Scholarship

Due process in antitrust enforcement has significant implications for better professional and accurate enforcement decisions. Not only can due process spur economic growth, raise government credibility, and limit the abuse of powers according to law, it also promotes competitive reforms in monopolized sectors and curbs corruption. Jurisdictions learn from the best practices in the investigation process, decisionmaking process, and the announcement and judicial review of antitrust enforcement decisions. By comparing the enforcement policies of China, the European Union, and the United States, this article calls for better disclosure of evidence, participation of legal counsel, and protection of the procedural and …


Anticompetitive Mergers In Labor Markets, Ioana Marinescu, Herbert J. Hovenkamp Jan 2019

Anticompetitive Mergers In Labor Markets, Ioana Marinescu, Herbert J. Hovenkamp

All Faculty Scholarship

Mergers of competitors are conventionally challenged under the federal antitrust laws when they threaten to lessen competition in some product or service market in which the merging firms sell. Mergers can also injure competition in markets where the firms purchase. Although that principle is widely recognized, very few litigated cases have applied merger law to buyers. This article concerns an even more rarefied subset, and one that has barely been mentioned. Nevertheless, its implications are staggering. Some mergers may be unlawful because they injure competition in the labor market by enabling the post-merger firm anticompetitively to suppress wages or salaries. …


A Preface To Neoclassical Legal Thought, Herbert J. Hovenkamp Jun 2011

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 …


Ip And Antitrust: Reformation And Harm, Christina Bohannan, Herbert J. Hovenkamp Jan 2010

Ip And Antitrust: Reformation And Harm, Christina Bohannan, Herbert J. Hovenkamp

All Faculty Scholarship

Antitrust and intellectual property law both seek to improve economic welfare by facilitating competition and investment in innovation. At various times both antitrust and IP law have wandered off this course and have become more driven by special interests. Today, antitrust and IP are on very different roads to reform. Antitrust reform began in the late 1970s with a series of Supreme Court decisions that linked the plaintiff’s harm and right to obtain a remedy to the competition - furthering goals of antitrust policy. Today, patent law has begun its own reform journey, but it is in a much earlier …


The Neal Report And The Crisis In Antitrust, Herbert J. Hovenkamp Mar 2009

The Neal Report And The Crisis In Antitrust, Herbert J. Hovenkamp

All Faculty Scholarship

The Neal Report, which was commissioned by Lyndon Johnson and published in 1967, is rightfully criticized for representing the past rather than the future of antitrust. Its authors completely embraced a theory of competition and industrial organization that had dominated American economic thinking for forty years, but was just in the process of coming to an end. The structure-conduct-performance (S-C-P) paradigm that the Neal Report embodied had in fact been one of the most elegant and most tested theories of industrial organization. The theory represented the high point of structuralism in industrial organization economics, resting on the proposition that certain …


Patents, Property, And Competition Policy, Herbert J. Hovenkamp Jan 2009

Patents, Property, And Competition Policy, Herbert J. Hovenkamp

All Faculty Scholarship

The decision to regulate involves the identification of markets where simple assignment of property rights is not sufficient to ensure satisfactory competitive results, usually because some type of market failure obtains. By contrast, if property rights are well defined when they are initially created and can subsequently be traded to some reasonably competitive equilibrium, then regulation is thought not to be necessary. In such cases the antitrust laws have a significant role to play in ensuring that the market can be as competitive as free trading allows. One problem with the patent system is that once a patent is granted …
