This Chapter reviews the theoretical literature on entry games and free entry equilibria. We show that a wide range of symmetric oligopoly models share common comparative statics properties. Individual profits and quantities decrease in the number of firms, and tend to competitive or...

This paper tests the hypothesis that a (partial) reason why cartels - collective but costly and non-binding price agreements - lead to higher prices in a Bertrand oligopoly could be because of a selection effect: decision-makers who are willing to form price agreements are more likely to be less...

This paper examines a dynamic game of exploitation of a common pool of some renewable asset by agents that sell the result of their exploitation on an oligopolistic market. A Markov Perfect Nash Equilibrium of the game is used to analyze the effects of a merger of a subset of the agents. We...

In this paper we analyze an infinite horizon dynamic oligopoly, producing a homogeneous good, with costly changes of output between the periods, and investments affecting marginal costs. The requirement of continuity of strategies and the weakest possible criterion of renegotiation-proofness,...

Antitrust authorities all over the world are concerned if a particularly aggressive competitor, a "maverick", is bought out of the market. One plausible determinant of acting as a maverick is behavioral: the maverick derives utility from acting competitively. We test this conjecture in the lab....

We model an industry in which a discrete number of firms choose the output of their differentiated products deciding whether or not to consider the impact of their decisions on aggregate output. We show that two threshold numbers of firms exist such that: below the lower one there is a unique...
