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.

评估河流和溪流恢复的影响：来自休闲捕鱼的证据

河流修复在世界范围内越来越多地用作保护措施和环境政策工具。尽管它们很受欢迎，但缺乏令人信服的经验证据表明河流修复实现了政策目标。利用独特的捕鱼旅行数据集，结合有关恢复的结构、空间和时间数据，我们研究了恢复对捕获率（一种可衡量的生态系统服务）的影响，然后评估这些变化对福利的影响。我们提供了强有力的证据，表明恢复导致捕获率持续增加，每年为一组拟议的未来恢复产生超过 600,000 美元的货币价值。(JEL Q26, Q51)
