We characterize equilibrium plant locations for a spatial multi-plant Cournot oligopoly in a circular city. Previous work demonstrates that for a two-plant duopoly, all four plants are equally spaced. We establish that the equilibrium location pattern is unique if there are two firms with an...

The paper analyzes spatial competition among firms that sell substitute and/or complementary products. The firms first choose locations on the perimeter of a circular city and then compete in quantities (à la Cournot). Both linear and convex (quadratic) transport costs are considered. In...

This paper extends the Stackelberg model to include any number of nonidentical firms and demonstrates significant counterintuitive results. For example, entry of an additional firm may increase the quantities and/or profits of some existing firms; it may also increase the total industry profit....
