The 2010 Horizontal Merger Guidelines propose a form of coordinated effects, referred to as "parallel accommodating conduct", that is claimed not to involve the usual evaluation of the ability of firms to detect compliance and punish non-compliance with respect to supracompetitive prices. That...

We hypothesize a particular source of cartel instability and explore its relevance to understanding cartel dynamics. The cartel instability is rooted in the observation that, upon cartel formation, the relative positions of firms are often fixed which may lead some growthconscious members to be...

A challenge for many cartels is avoiding a destabilizing increase in non-cartel supply in response to having raised price. In the case of the German cement cartel that operated over 1991-2002, the primary source of non-cartel supply was imports from Eastern European cement manufacturers....

In the context of an infinitely repeated Prisoners' Dilemma, we explore how cooperation is initiated when players communicate and coordinate through their actions. There are two types of players - patient and impatient - which are private information. An impatient type is incapable of...

In the context of an infinitely repeated capacity-constrained price game, we endogenize the composition of a cartel when .rms are heterogeneous in their capacities. When .rms are sufficiently patient, there exists a stable cartel involving the largest .rms. A .rm with sufficiently small capacity...

This paper identifies conditions under which an industry-wide practice of posted (or list) pricing is a plus factor sufficient to conclude that firms violated Section 1 of the Sherman Act. For certain classes of markets, it is shown that, under competition, all firms setting a list price with a...

A corporate leniency program provides relief from government penalties to the first member of a cartel to come forward and cooperate with the authorities. This study explores the incentives to apply for leniency when each cartel member has private information as to the likelihood that the...

This new edition of the leading text on business and government focuses on the insights economic reasoning can provide in analyzing regulatory and antitrust issues. Departing from the traditional emphasis on institutions, Economics of Regulation and Antitrust asks how economic theory and...

This article examines endogenous cartel formation in the presence of a competition authority. Competition policy is shown to make the most inclusive stable cartels less inclusive. In particular, small firms that might have been cartel members in the absence of a competition authority are no...
