The Dixit (1980) hypothesis that incumbents use investment in capacity to deter potential entrants has found little empirical support. Bagwell and Ramey (1996) propose a model where, in the unique game-theoretic prediction based on forward induction or iterated elimination of weakly-dominated...

We offer a new explanation of equilibrium rationing. As is well known, a monopolist selling a durable good and not able to commit to a price sequence has an incentive to lower the price once the consumers with the greatest willingness to pay have bought, but this induces consumers to postpone...

We examine the strategic use of Corporate Social Responsibility (CSR) in imperfectly competitive markets. The level of CSR determines the weight a firm puts on consumer surplus in its objective function before it decides upon supply. First, we consider symmetric Cournot competition and show that...

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...

In this paper we model the case of an international non-renewable resource monopolist as a dynamic game between a monopolist and n importing countries governments, and we investigate whether a tariff on resource imports can be advantageous for the consumers of the importing countries when the...

We consider a monopolist who sells identical objects of common but unknown value in a herding-prone environment. Buyers make their purchasing decisions sequentially, and rely on a private signal as well as previous buyers' actions to infer the common value of the object. The model applies to a...
