We study the optimal control of a pollutant that accumulates with a delay.We find that optimal paths are, in general, non-monotonic and oscillatory, but monotonic if the objective function is additively separable. Hence, using additively separable objective functions as an approximation to a...

Simulation methods are revolutionizing the practice of applied economic analysis. In this book, leading researchers from around the world discuss interpretation issues, similarities and differences across alternative models, and propose practical solutions for the choice of the model and...

Emissions taxes, tradeable emission permits and voluntary compliance policies are becoming the instruments of choice in controlling environmental problems at the national and international level. Careful design of these policies in second-best environments is a very important factor for their...
