This paper investigates the properties of two types of cost restrictions that guarantee the existence of an equilibrium in pure strategies in Bayesian spatial competition models with heterogenous firms.

We study when a monopolistically-competitive firm may optimally choose to limit the size of its market. This may be the case when the cost of serving the market with geographically dispersed customers is increasing in size. We also investigate the incentives faced by a firm to limit the reach of...

The paper extends the Salop model of localized competition by allowing firms to have heterogeneous costs. We provide a general but highly tractable analytical solution for the equilibrium prices, and we study the long-run properties of the model using two different entry games. We show that cost...
