本文考虑了解决该评价问题的不同方法。我强调了计划影响中的异质性在定义感兴趣的评估参数和解释估计的计划影响中的作用。我讨论了社会实验的优点和缺点，并得出结论，它们需要仔细实施和解释。我回顾和评论了两种流行的非实验性评价方法：差异差异法和倾向得分匹配法。我发现，前者依赖于与经验数据不一致的假设，而后者并不是所有评估问题的神奇解决方案。最后，我论证了关注数据质量和一般均衡效应的重要性。
This paper considers different methods for solving the evaluation problem. I highlight the role of heterogeneity in program impacts in defining evaluation parameters of interest and in interpreting estimated program impacts. I discuss the strengths and weaknesses of social experiments and conclude that they require careful implementation and interpretation. I review and critique two popular non-experimental evaluation methods: difference-in-differences and propensity score matching. I find that the former relies on assumptions at odds with the empirical data and that the latter is not a magical solution to all evaluation problems. Finally, I argue for the importance of paying attention to data quality and general equilibrium effects.
