Anticompetitive conduct toward upstream trading partners may have the effect of benefiting downstream consumers even as the conduct harms the firms’ workers or suppliers. Defendants may attempt to justify their upstream conduct—and may rely on the ancillary restraints doctrine in doing so—on the grounds that the restraints create efficiencies benefitting downstream purchasers, rather than focusing solely on the impact of the restraints on the workers or suppliers in the upstream market. Such balancing of harms against out-of-market benefits achieved by a different group should be rejected by antitrust doctrine generally, and specifically in the case of harms to workers.

Drawing upon data from the largest cross-country study of labor market concentration to date, this Essay analyzes the level of concentration of labor-input markets in Europe and North America and provides a comparative perspective on employers’ monopsony power. It explores the characteristics of monopsony in labor markets and documents its impact by looking at the magnitude of employer concentration in selected jurisdictions.

Conflict of Laws? Tensions Between Antitrust and Labor Law
Matthew Dimick
Professor of Law, University at Buffalo School of Law.

Thanks to the editors of the University of Chicago Law Review for the invitation to participate in this important symposium. Thanks also to symposium participants for thoughtful and constructive comments and questions. Special thanks go to Cynthia Estlund, Hiba Hafiz, Hebert Hovenkamp, Eric Posner, and César Rosado Marzán for specific suggestions and pointed comments; and to Racquel Bozzelli for research assistance.

Not long ago, economists denied the existence of monopsony in labor markets. Today, scholars are talking about using antitrust law to counter employer wage-setting power. While concerns about inequality, stagnant wages, and excessive firm power are certainly to be welcomed, this sudden about-face in theory, evidence, and policy runs the risk of overlooking some important concerns.

Losing Leverage: Employee Replaceability and Labor Market Power
Cynthia Estlund
Catherine A. Rein Professor of Law, New York University School of Law.

I would like to thank Daniel Hemel, Jonah Gelbach, and the participants in the Law and Labor Market Power Symposium held at the University of Chicago in March 2022 for their helpful comments on an earlier draft, and Krishnan Sethumadhavan for excellent research assistance.

Workers’ labor market power matters enormously to their lives at work and beyond. And most workers have too little of it. This Essay highlights one underappreciated set of factors in the decline of workers’ labor market power and explores policy levers that might help to rebalance the bargaining field.

Due to a lack of competition among employers in the labor market, employers have monopsony power, or power to pay workers less than what the workers contribute to the employers’ bottom line. “Worker power” is workers’ ability to obtain higher wages and better working conditions.

Worker Welfare and Antitrust
Herbert Hovenkamp
James G. Dinan University Professor, University of Pennsylvania Carey Law School and the Wharton School.

Thanks to Erik Hovenkamp & Ioana Marinescu for comments.

The field of antitrust and labor has gone through a profound change in orientation. For the great bulk of its history, labor was viewed by antitrust enforcers as a competitive threat.

Horizontal Collusion and Parallel Wage Setting in Labor Markets

Eric Posner took a position at the Antitrust Division in the Department of Justice after this paper was substantially completed; the views expressed in this paper do not necessarily reflect those of the Department of Justice.

Horizontal collusion among employers to suppress wages has received almost no attention in the academic literature, in contrast with its more familiar cousin, product-market collusion. The similar economic analysis of labor and product markets might suggest that antitrust should regulate labor and product markets in the same way.

On Firms
Sanjukta Paul
Professor of Law, University of Michigan Law School.

Special thanks to Steve Salop, Nathan Tankus, Naomi Lamoreaux, Nicolas Cornell, Marshall Steinbaum, J.J. Prescott, Albert Choi, and Luke Herrine for valuable discussions and comments. I am particularly grateful to Steve Salop for going well above and beyond the call of duty in critically and sympathetically engaging the ideas contained herein. I also thank participants in the University of Chicago Law Review Symposium on Law & Labor Market Power, in the Michigan Law School faculty workshop, and in the Michigan Law & Economics Workshop. Finally, I am very grateful to the student editors of the Law Review for their valuable contributions to this Essay and for preparing it for publication.

This Essay is about firms as a type of economic coordination and about how we think about them in relation to other forms of coordination as well as in relation to competition and markets. A prominent stream of thought about firms—which has both strongly influenced contemporary competition law and, more indirectly, served as a support to the fundamental ideas of neoclassical price theory that guide many areas of law and policy—ultimately explains and justifies the centralization of both decision-making rights and flows of income from economic activity on productive efficiency grounds.

Coercive Rideshare Practices: At the Intersection of Antitrust and Consumer Protection Law in the Gig Economy
Christopher L. Peterson
John J. Flynn Endowed Professor of Law, University of Utah.
Marshall Steinbaum
Assistant Professor of Economics, University of Utah.

The authors thank David Seligman, Rachel Dempsey, Sandeep Vaheesan, Brian Callaci, Sanjukta Paul, James Brandt, Steve Salop, Laura Alexander, Leonard Sherman, and other collaborators who provided helpful comments on earlier publications and drafts, as well as the organizers and participants in the University of Chicago Law Review Symposium “Law and Labor Market Power.” Steinbaum consulted for Towards Justice during its rideshare antitrust investigation while this Article was in preparation.

This Essay considers antitrust and consumer protection liability for coercive practices vis-à-vis drivers that are prevalent in the rideshare industry. Resale price maintenance, nonlinear pay practices, withholding data, and conditioning data access on maintaining a minimum acceptance rate all curtail platform competition, sustaining a high-price, tacitly collusive equilibrium among the few incumbents.
