Field experiments in the developed world: an introduction
介绍了发达国家中实地实验的关键概念、理论检验应用、局限性及新兴领域，帮助学者理解如何用实地实验回答教育、税收、金融等政策相关问题。
Field experiments represent a relatively new area in economics to understand the causal links from one variable to another. They have been used by academics to help answer interesting and policy-relevant questions in the developed world relating to educational attainment, tax avoidance, consumer finance, negative externalities, charitable giving, and labour market contracts. In this paper we bring together the key ideas behind the different variants of field experiments, how field experiments have been used to test theory, their limitations, and the new areas currently being opened up by field experiments.
