The Impact of Policies and Land Characteristics on Potential Groundwater Pollution in Wisconsin
构建了一个实证框架，量化商品计划和化学使用税对威斯康星州潜在地下水污染的广泛边际效应，发现增加玉米面积减少计划率比化学税或目标价格政策更能减少高污染面积。
Abstract In this paper we present an empirical framework for quantifying the extensive margin effects of commodity programs and chemical‐use taxes on potential groundwater pollution in Wisconsin. The approach emphasizes the role of the joint distribution of crops and site characteristics in determining policy impacts on groundwater contamination. The results indicate that for a given reduction in total polluting acreage an increase in the Acreage Reduction Program rate for corn is well targeted and would reduce high‐polluting acreage more than a chemical‐use tax or a target price policy in the areas where it might be needed most.
