随机实验已经成为发展经济学研究中的一种流行工具，也受到了一些批评。本文回顾了最近的文献，并讨论了这种方法在理论和实践中的优势和局限性。我们认为，随机实验的主要优点是，由于研究人员和实施者之间的密切合作，他们允许估计的参数，否则将无法评估。我们讨论了已经提出的关于实验的关注，并普遍得出结论，虽然真实的，他们往往不是具体的实验。最后，我们讨论了理论与实验之间的关系。
Randomized experiments have become a popular tool in development economics research and have been the subject of a number of criticisms. This paper reviews the recent literature and discusses the strengths and limitations of this approach in theory and in practice. We argue that the main virtue of randomized experiments is that, owing to the close collaboration between researchers and implementers, they allow the estimation of parameters that would not otherwise be possible to evaluate. We discuss the concerns that have been raised regarding experiments and generally conclude that, although real, they are often not specific to experiments. We conclude by discussing the relationship between theory and experiments.
