活动简介:
Emission control has aroused tremendous attention worldwide. Government have been using regulations to reduce environment damage due to pollution while still trying to maximize the social welfare. Potential regulatory instruments can be categorized into two kinds: price instruments and quantity instruments. There is much discussion on which instrument is the best way to regulate pollution emissions, but no consensus has been reached. This motivates us to compare these instruments and identify the conditions under which each instrument is preferable over the other. In our paper, we demonstrate that, in terms of social welfare, the comparison between the price and the quantity instruments depends on both the pollution damage coefficient and the level of market volatility. This contrasts with the result that the comparison only depends on the damage coefficient (see Weitzman 1974). We further illustrate the reason for the differences. We also consider factors such as competition, abatement efforts and show that our results mostly hold in those settings. (This is a joint work with Guokai Li and Pin Gao)
