This study characterizes the corporate leniency policy that minimizes the frequency with which collusion occurs. Though it can be optimal to provide only partial leniency, plausible sufficient conditions are provided whereby the antitrust authority should waive all penalties for the first firm...

Price-fixing is characterized when firms are concerned about creating suspicions that a cartel has formed. Antitrust laws have a complex effect on pricing as they interact with the conditions determining the internal stability of the cartel. Dynamics are driven by two forces - the sensitivity of...

Collusion under imperfect monitoring is explored when firms?prices are private information and their quantities are public information; an information structure consistent with several recent price-fixing cartels such as those in lysine and vitamins. For a class of symmetric duopoly games, it is...

Standard methods in the U.S. for calculating antitrust damages in price-fixing cases is shown to create a strategic incentive for firms to price above the non-collusive price after the cartel has dissolved. This results in an overestimate of the but for price and an underestimate of the level of...

Previous research exploring the effect of corporate leniency programs has modelled the oligopoly stage game as a Prisoners?Dilemma. Using numerical analysis, we consider the Bertrand price game and allow the probability of detection and penalties to be sensitive to firms?prices. Consistent with...

This paper characterizes collusive pricing patterns when buyers may detect the presence of a cartel. Buyers are assumed to become suspicious when observed prices are anomalous. We find that the cartel price path is comprised of two phases. During the transitional phase, price is generally rising...

Price dynamics are characterized when a price-fixing cartel is concerned about creating suspicions of the presence of a cartel A dynamical extension of static models yields the counterfactual prediction that the cartel initially raises price and then gradually lowers it An alternative...

In reviewing the theoretical and empirical literature on collusion, this paper distills methods for detecting cartels and distinguishing collusion from competition.

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...

This paper distills and organizes facts about cartels from about 20 European Commission decisions over 2000–2004. It describes the properties of a collusive outcome in terms of the setting of price and a market allocation, monitoring of agreements with respect to price but more importantly...
