Abstract

Abstract This paper surveys six widely-used non-experimental methods for estimating treatment effects (instrumental variables, regression discontinuity, direct matching, propensity score matching, linear regression and non-parametric methods, and difference-in-differences), and assesses their internal and external validity relative both to each other and to randomized controlled trials. While randomized controlled trials can achieve the highest degree of internal validity when cleanly implemented in the field, the availability of large, nationally representative data sets offers the opportunity for a high degree of external validity using non-experimental methods. We argue that each method has merits in some context and they are complements rather than substitutes.
发展经济学中的实验与非实验方法:一个多孔的辩证法
摘要:本文综述了常用的6种治疗效果估计的非实验方法(工具变量法、回归不连续法、直接匹配法、倾向评分匹配法、线性回归和非参数法、差中差法),并评估了它们之间以及相对于随机对照试验的内部效度和外部效度。虽然随机对照试验在实地实施时可以达到最高程度的内部效度,但具有全国代表性的大型数据集的可用性为使用非实验方法获得高度的外部效度提供了机会。我们认为每种方法在某些情况下都有优点,它们是互补而不是替代。

期刊介绍: The Journal of Globalization and Development (JGD) publishes academic research and policy analysis on globalization, development, and in particular the complex interactions between them. The journal is dedicated to stimulating a creative dialogue between theoretical advances and rigorous empirical studies to push forward the frontiers of development analysis. It also seeks to combine innovative academic insights with the in-depth knowledge of practitioners to address important policy issues. JGD encourages diverse perspectives on all aspects of development and globalization, and attempts to integrate the best development research from across different fields with contributions from scholars in developing and developed countries. Topics: -Economic development- Financial investments- Development Aid- Development policies- Growth models- Sovereign debt
