The standard Ricardian model of competition has a fixed number of firms, each with limited capacity and differential exogenous costs or qualities. In this paper, we introduce a real entry process by formulating a multistage Ricardian equilibrium model with free entry and stochastic product...

We model a dynamic duopoly in which firms can potentially drive their rivals from the market. A consequence is that, for some ranges of parameters, the static Cournot equilibrium outcome cannot be sustained in an infinitely repeated setting. In those cases, there is a Markov perfect equilibrium...

We consider a general economic equilibrium model with divisible commodities and price functions based on the material balance condition. We show that mechanisms for attaining its solution points are closely related to information exchange schemes attributed to the model within its basic...

In this paper we consider a class of economies with a finite number of divisible commodities, linear production technologies, and indivisible goods, and a finite number of agents. This class contains several well-known economies with indivisible goods and money as special cases. It is shown that...
