Disagreement over the form of regulation of greenhouse gasses motivates a comparison of market based and command and control policies. More efficient policies can increase aggregate marginal abatement cost, resulting in higher emissions. Multiple investment equilibria and “regulatory...

We characterize the open-loop and the Markov perfect Stackelberg equilibria for a differential game in which a cartel and a fringe extract a nonrenewable resource. Both agents have stock dependent costs. The comparison of initial market shares, across different equilibria, depends on which firm...

A linear-quadratic dynamic oligopoly model is developed and applied to the world coffee export market. The model nests various market structures using either open-loop or feedback strategies. The theoretical properties of this model are described. For given observed behavior, the assumption of...

The effect of risk aversion on Nash equilibrium trade restrictions is studied using numerical methods. An increase in a nation's level of risk aversion can lead to either an increase or decrease in its equilibrium restriction and either an increase or decrease in its rival's restriction. The...
