Evaluating the Effects of River and Stream Restorations: Evidence from Recreational Fishing
利用垂钓旅行数据与修复工程的结构、空间和时间信息，研究河流修复对垂钓捕获率这一可测量生态系统服务的影响，并评估其福利后果。
River restorations are increasingly used worldwide as conservation measures and environmental policy tools. Despite their popularity, there is a lack of compelling empirical evidence that river restorations achieve policy goals. Exploiting a unique dataset of fishing trips combined with structural, spatial, and temporal data on restorations, we study the effects of restorations on catch rate, a measurable ecosystem service, and then evaluate the welfare consequences of these changes. We provide robust evidence that restorations lead to persistent increases in catch rates that generate a monetary value of over $600,000 annually for a proposed set of future restorations. <i></i>
