This paper examines the relative contributions of three factors to economic efficiency and pollution abatement. The first is price efficiency, achieved through the removal of unnecessary subsidies--surprisingly widespread--for polluting activities; the second, managerial efficiency; and the...

This paper presents a dynamic simulation model for the quantitative analysis of environmental policy, incorporating key features of technical progress in abatement and an explicit role for policy in determining costs and pollution over time. The model is used to develop scenarios for PM, SO2,...
