This research project investigated the viability of water quality trading (WQT) as a practical water quality conservation policy. We examined, theoretically and empirically, the welfare properties of the two WQT systems, the trading ratio system (TRS), proposed by Hung and Shaw (JEEM, 2005), and the damage-denominated trading ratio system (DTRS), proposed by Farrow et al.(Land, 2005). Our main findings were(i) TRS tends to preclude welfare-improving trades whereas DTRS tends to encourage welfare-decreasing trades under realistic conditions of river systems(ii) their relative efficiency depends on the geographic distribution of polluting sources in the river basin, and(iii) nonetheless, the efficiency loss due to failing to get the total supply of permits is larger than that due to failing to get the spatial prices of permits. Furthermore, we identified the total maximum daily load (TMDL) regulation and its associated WQT policy for phosphorus pollution in the Minnesota River basin as a study area for our empirical research. We estimated the (marginal) abatement costs of phosphorus removal at 44 water treatment plants under the TMDL regulation. The project is currently at the stage of implementing our empirical simulation work using the estimated abatement costs.

本研究探讨水质交易(WQT)作为一种实用的水质保护政策的可行性。我们从理论和实证两个方面考察了两种WQT制度的福利性质，即Hung和Shaw(Jeem，2005)提出的交易比率制度(TRS)和Farrow等人(land，2005)提出的损害计价交易比率制度(DTRS)。我们的主要发现是：(I)在现实的水系条件下，TRS倾向于排除福利改善交易，而DTRs倾向于鼓励福利减少的交易；(Ii)它们的相对效率取决于流域内污染源的地理分布；(Iii)尽管如此，由于无法获得许可证的总供应量而造成的效率损失仍大于因无法获得许可证的空间价格而造成的效率损失。此外，我们确定了明尼苏达州流域磷污染的总最大日负荷(TMDL)调节及其相关的WQT政策作为我们的实证研究区域。根据TMDL法规，我们估算了44个水处理厂的除磷(边际)成本。该项目目前正处于利用估计的减排成本实施我们的经验模拟工作的阶段。
