中文摘要
信息提供实验使研究者能够通过改变受访者可获得的信息集来检验经济理论并回答与政策相关的问题。我们综述了经济学中运用信息提供实验的新兴文献，并讨论了其在宏观经济学、金融学、政治经济学、公共经济学、劳动经济学和健康经济学中的应用。我们还讨论了设计方面的考量，并就以下方面提供了最佳实践建议：(i) 测量信念；(ii) 设计信息干预；(iii) 测量信念更新；(iv) 处理潜在的混杂因素，如实验者需求效应；(v) 使用在线样本组招募受访者。我们最后讨论了典型的效应量并提供了样本量建议。(JEL C90, D83, D91)
Abstract
Information provision experiments allow researchers to test economic theories and answer policy-relevant questions by varying the information set available to respondents. We survey the emerging literature using information provision experiments in economics and discuss applications in macroeconomics, finance, political economy, public economics, labor economics, and health economics. We also discuss design considerations and provide best-practice recommendations on how to (i) measure beliefs; (ii) design the information intervention; (iii) measure belief updating; (iv) deal with potential confounds, such as experimenter demand effects; and (v) recruit respondents using online panels. We finally discuss typical effect sizes and provide sample size recommendations.(JEL C90, D83, D91)
