When firms set prices and face entry costs, efficiency in production and in entry are not simultaneously achieved, generating the possibility that regulatory interventions can lead to efficiency enhancements. We show through the Bertrand model that in markets with public entry and regular...

"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 an industry where firms compete via supply functions, the set of equilibrium outcomes is large. If decreasing supply functions are ruled out, this set is reduced significantly, but remains large. Specifically, the set of prices that can be sustained by supply function equilibria is the...

Whereas in the absence of capacity constraints the Cournot outcome is the unique coalition-proof supply function equilibrium outcome, the presence of capacity constraints may enlarge the set of equilibrium outcomes. Interestingly, if capacities are sufficiently asymmetric the new equilibrium...

This paper provides a novel rationale for the regulation of market size when heterogeneous firms compete. A regulator seeks to maximize total welfare by choosing the number of firms allowed to enter the market, e.g. by issuing a certain number of licenses. Opening up the market for more firms...
