干旱响应型水资源回购的反向拍卖：来自协同设计实验室与实地实验的证据
Reverse auctions for drought‐responsive water buybacks: Evidence from co‐designed lab and field experiments
摘要
Protecting endangered aquatic species while sustaining farming communities can require water buyback programs that are both cost‐effective and responsive to the variability and unpredictability of drought conditions. Working in close partnership with The Nature Conservancy and the Georgia Water Planning and Policy Center, we co‐design parallel laboratory experiments and high‐stakes framed field experiments to evaluate alternative reverse auction designs. The framed field experiments involved over $650,000 in real payments to irrigators making decisions about their own fields. Results from this lab‐to‐field experimental framework show that streamflow‐based targeting improves cost‐effectiveness relative to acre‐based targeting, and that flexible contracts linking irrigation suspension to actual streamflow conditions outperform rigid contracts when commitments must be made before drought conditions are known. This study demonstrates how integrated lab and framed field experiments can be embedded within real‐world institutional settings to generate policy‐relevant evidence for agri‐environmental programs.
中文摘要
保护濒危水生物种与维持农业社区生计，可能需要既具成本效益又能应对干旱条件多变性和不可预测性的水回购计划。我们与大自然保护协会和佐治亚州水资源规划与政策中心密切合作，共同设计了平行实验室实验和高风险框架田野实验，以评估替代性反向拍卖设计。框架田野实验涉及超过65万美元的实际支付，用于灌溉者就其自有田地作出决策。这一从实验室到田野的实验框架结果表明，相对于基于面积的定向，基于流量的定向提高了成本效益；并且当承诺必须在干旱条件未知之前作出时，将灌溉暂停与实际流量条件挂钩的灵活合同优于刚性合同。本研究展示了如何将实验室实验与框架田野实验相结合并嵌入现实制度环境，从而为农业环境项目生成具有政策相关性的证据。
