Abstract One innovative way to solve water pollution problems is through water quality trading programs. However, participation levels and the price of offsets/credits tend to be low, which raises questions about the effectiveness of the policy. To offer more tools for policymakers, this paper provides a method for predicting participation in performance-based water quality trading programs, which accounts for field-level heterogeneity. We frame the economic problem in terms of derived demand, i.e., as a farmer Best Management Practice (BMP) input decision rather than a farmer output decision about supplying offsets. Specifically, this approach offers a straightforward way for farmers and policymakers to frame the decision to add a marginal unit of BMP—rather than a marginal unit of abatement—and take advantage of existing performance-based scientific models of nutrient loading. The paper uses actual market and field data in Maryland to illustrate the method and demonstrate the heterogeneity within and among BMPs. We also run sensitivity analyses to test the effects of different levels of farmer subsidies and transaction costs. The application results find, first, the extensive field-level heterogeneity in BMP abatement productivity. Second, the results show that far more farmers will adopt the high-abatement, medium-cost buffer BMPs than low-abatement, low-cost and high-abatement, high-cost BMPs.

一种预测参与基于绩效的水质交易计划的方法

摘要 解决水污染问题的一种创新方法是通过水质交易计划。然而,参与水平和抵消/信贷的价格往往较低,这引发了对政策有效性的质疑。为了为政策制定者提供更多工具,本文提供了一种预测参与基于绩效的水质交易计划的方法,该计划考虑了现场水平的异质性。我们根据派生需求来构建经济问题,即作为农民最佳管理实践 (BMP) 的输入决策,而不是关于提供补偿的农民输出决策。具体来说,这种方法为农民和政策制定者提供了一种直接的方法来制定增加 BMP 边际单位而不是减排边际单位的决定,并利用现有的基于绩效的营养负荷科学模型。本文使用马里兰州的实际市场和现场数据来说明该方法并证明 BMP 内部和之间的异质性。我们还进行了敏感性分析,以测试不同水平的农民补贴和交易成本的影响。应用结果发现,首先,BMP 减排生产力存在广泛的现场级异质性。其次,结果表明,与低减排、低成本和高减排、高成本 BMP 相比,更多的农民将采用高减排、中等成本的缓冲 BMP。本文使用马里兰州的实际市场和现场数据来说明该方法并证明 BMP 内部和之间的异质性。我们还进行了敏感性分析,以测试不同水平的农民补贴和交易成本的影响。应用结果发现,首先,BMP 减排生产力存在广泛的现场级异质性。其次,结果表明,与低减排、低成本和高减排、高成本 BMP 相比,更多的农民将采用高减排、中等成本的缓冲 BMP。本文使用马里兰州的实际市场和现场数据来说明该方法并证明 BMP 内部和之间的异质性。我们还进行了敏感性分析,以测试不同水平的农民补贴和交易成本的影响。应用结果发现,首先,BMP 减排生产力存在广泛的现场级异质性。其次,结果表明,与低减排、低成本和高减排、高成本 BMP 相比,更多的农民将采用高减排、中等成本的缓冲 BMP。
