随机对照试验如何帮助改进共同农业政策的设计？【转】

简单中文摘要翻译：我们说明了随机对照试验（RCT）如何用于评估共同农业政策（CAP）替代设计的影响。 我们选择了四个与CAP的不同组成部分相关的政策设计问题，并提出了广泛的经济问题：助推，协调失败，公平效率权衡，契约设计。 根据发展中国家和发达国家农业和社会政策的实例，我们表明RCT为类似的设计问题提供了有用的严谨证据，表明它们也可以用来帮助改进CAP的组成部分。

Abstract: We illustrate how randomised controlled trials (RCTs) could be used to evaluate the impact of alternative designs of the common agricultural policy (CAP). We select four policy-design issues which relate to different components of the CAP and raise a wide range of economic questions: nudges, coordination failures, equity-efficiency trade-offs, contract design. Based on examples from agricultural and social policies in developing and developed countries, we show that RCTs have provided useful rigorous evidence on similar design issues, suggesting that they could also be leveraged to help improve components of the CAP.
