The Relative Efficiency of Agricultural Source Water Pollution Control Policies
比较了四种农业面源污染控制策略的预期效率，发现针对管理实践的激励措施通常优于其他方法，尤其考虑了信息不对称和污染随机性。
Abstract This paper examines the relative expected efficiency of four general strategies which have been proposed for achieving agricultural nonpoint pollution abatement. Emphasis is placed on the implications of differential information about the costs of changes in farm management practices, the impracticality of accurate direct monitoring, and the stochastic nature of nonpoint pollution. The possibility of using hydrological models to reduce, but not eliminate, the uncertainty about the magnitude of nonpoint loadings is incorporated into the analysis. The principal result is that appropriately specified management practice incentives should generally outperform estimated runoff standards, estimated runoff incentives, and management practice standards for reducing agricultural nonpoint pollution.
