We develop a method to screen for local cartels. We first test whether there is statistical evidence of clustering of outlets that score high on some characteristic that is consistent with collusive behavior. If so, we determine in a second step the most suspicious regions where further...

The paper is an extension of the contributions provided by Aghion and Bolton (1987), Chung (1994, 1996), and Spier and Whinston (1995)--among others--to the analysis of the trade-off between the enforcement of incomplete contracts characterised by specific investments and the market foreclosure...

Multiemployer collective bargaining relationships between unions and employer associations easily devolve into legalized cartels. Once unions establish themselves as the bargaining representative for employers’ employees, the employers have much to gain from banding together as an association,...

This chapter reviews the law and economics of predatory pricing. Areeda and Hovenkamp (2006, 323) noted that other areas of the law of monopolization are "in much the same position as the theory of predatory pricing was in the 1970s: no shortage of theories, but a frightening inability of courts...

This chapter surveys the legal and economic literatures on the antitrust analysis of tying arrangements and exclusive dealing contracts. We review the analytical framework applied under U.S. antitrust law to tying, bundling and exclusive dealing arrangements as well as the existing theoretical...

This paper presents an overview of what economists can say about vertical constraints by multi-sided platforms at this stage in the development of our knowledge about the economics of these businesses. It describes the general procompetitive and anticompetitive uses of vertical restraints by...

This paper clarifies the relation between per se hub-and-spoke and vertical rule of reason antitrust analysis, the tension between which is illustrated with a detailed examination of the Apple e-books case

This paper develops a model that formalizes several connections between mergers, collusion and competition policy. In equilibrium, firms may merge to make collusion sustainable when it cannot be sustained with the original set of firms. A rise in the probability of detecting and prosecuting...

This paper introduces a number of game-theoretic tools to model collusive agreements among firms in vertically differentiated markets. I firstly review some classical literature on collusion between two firms producing goods of exogenous different qualities. I then extend the analysis to a...

Scholars and courts have long debated whether and when "parallel pricing" — adoption of the same price by every firm in a market — should be considered a violation of antitrust law. But there has been a comparative neglect of the importance of "parallel exclusion" — conduct, engaged in by...
