ABSTRACT:We develop an integrated assessment model for spatially simulating water quality and social welfare from linked ecosystem services that extends prior modeling by incorporating a broader suite of pollutants than conventionally measured factors like phosphorus and nitrogen. Beyond demonstrating the feasibility of such a model, we provide guidance on the impact of omitting or holding constant relevant pollutants and their effect on estimates of water quality and willingness to pay. Applying the model to Narragansett Bay, we find that recent wastewater treatment upgrades and a legacy network of dams are providing millions in annual value to adjacent residents. (JEL Q53, Q57)

将其他污染物纳入综合评估模型，以估算水质的非市场效益

摘要：我们开发了一个综合评估模型，用于从关联的生态系统服务中对水质和社会福利进行空间模拟，该模型通过纳入比常规测量的磷和氮等因素更广泛的污染物套件来扩展先前的模型。除了证明这种模型的可行性之外，我们还提供了关于忽略或保持相关污染物不变的影响及其对水质估计和支付意愿的影响的指导。将该模型应用于纳拉甘西特湾，我们发现最近的废水处理升级和遗留的水坝网络每年为邻近居民提供数百万美元的价值。(JEL Q53、Q57)
