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...

In this paper, we present a model of implementation where infea- sible allocations are converted into feasible ones through a process of renego- tiation that is represented by a reversion function. We describe the maximal set of Social Choice Correspondences that can be implemented in Nash Equi-...
