Recent contributions show that climate agreements with broad participation can be implemented as weakly renegotiation-proof equilibria in simple models of greenhouse gas abatement where each country has a binary choice between cooperating (i.e., abate emissions) or defecting (no abatement). Here...

We explore the efficacy of price and quantity controls as environmental policy instruments in a stochastic setting in which agents are risk averse. We demonstrate that the assumption of risk aversion may improve the performance of a tax relative to that of a system of tradable quotas, and that...

When a monopolistic hydro producer interacts with a competitive thermal fringe, the short-run revenue function of the hydro monopolist is non-concave. This implies that even if the demand function is stationary, equilibrium prices may fluctuate through the year. For given capacities, both hydro...
