Electronic coordination links markets at different locations that have initially been (partially) separated by transport costs. Rising competitive pressure should in turn affect incentives to differentiate products. In this paper investment decisions concerning transport cost reduction and...

In this paper we provide necessary and sufficient conditions for the existence of a Cournot equilibrium when demand is rho-linear and firms are identical and produce under constant returns to scale. We focus on inelastic and convex demand which yields non concave profit functions.We show that...
