Evidence of Treatment Spillovers Within Markets
提出一种方法，用于推断市场内部分个体接受处理时是否存在溢出效应，并利用法国失业培训项目的行政数据，发现当地劳动力市场中个体潜在结果随处理比例变化，证明存在互动效应。
This paper provides a method to infer the presence of treatment spillovers within markets where a fraction of agents is treated. We model individual outcomes as functions of the assigned treatment status and the distribution of assigned treatments in a market. We develop a two-step identification and estimation method, focusing first on the treatment distribution among individuals within markets and then on the treatment distribution across markets. We apply our approach to training programs for unemployed individuals in France using rich administrative data. Our results provide evidence of interactions within local labor markets as potential individual outcomes vary with the proportion of treated individuals.
