IMPACTS OF TAXES TO REDUCE AGRICHEMICAL USE WHEN FARM POLICY IS ENDOGENOUS
研究了美国玉米生产中，当农业收入支持政策随环境政策调整时，对污染性化学投入征税的成本和效果，发现补偿性政策调整会大幅增加成本并降低环境措施的有效性。
The economic impacts of policies to reduce water pollution from agriculture have been explored in a number of studies. A standard assumption in this literature is that farm income support policies are given. However, the modern public choice view of agricultural policy suggests that significant environmental initiatives in agriculture would likely be accompanied by changes in farm income policies to protect those with a significant stake in agriculture. We explore the potential effects of such compensating adjustments on the costs and effectiveness of taxes on polluting chemical inputs in US corn production. We find that compensating farm policy adjustments can greatly increase the costs and reduce the effectiveness of the environmental protection measure. The results also indicate the potentially high costs of poor policy co‐ordination.
