We re-examine the regulatory role of a public firm in an environment of private but correlated information about industry costs. We study three regimes of mixed-market interaction involving both public and private firms: a symmetric Bayesian-Nash equilibrium, an asymmetric Bayesian equilibrium...

We construct a model of long-term bilateral competition between the supplier of an exhaustible resource and a consuming country capable of producing a perfect substitute for the resource. The technology for producing the substitute is known, and the strategy of the consuming country is to choose...

This article sets out a theory of market structure with sequential entry. We characterize the perfect Nash equilibrium to the entry game in several propositions. First, equilibria never involve excess capacity. Second, a sufficient statistic for the entry of any firm is that its profits are...

Empirical evidence suggests that past levels of protection are significant determinants of current levels of protection. We investigate dynamic interactions among interest groups and resulting endogenous links between current and future trade policies. We explore these intertemporal links in a...
