论文摘要
青年教育的一个关键要素是他们对历史和艺术遗产的敏感性。我们分析了在佛罗伦萨（意大利）进行的一次实地实验，以评估分配给高中课程的适当激励措施可能会在业余时间引起青少年参观博物馆。不合规和溢出效应使这种集群鼓励设计具有挑战性的影响。我们建议通过根据其合规行为来定义单位的子选集并将其友谊网络上的信息作为调解人来融合主要分层和因果关系。我们正式定义了主要自然直接和间接效应以及主控制的直接和溢出效应，并将其用来将溢出物从其他因果通道中解散。我们采用贝叶斯方法进行推理。
A key element in the education of youths is their sensitization to historical and artistic heritage. We analyze a field experiment conducted in Florence (Italy) to assess how appropriate incentives assigned to high-school classes may induce teens to visit museums in their free time. Non-compliance and spillover effects make the impact evaluation of this clustered encouragement design challenging. We propose to blend principal stratification and causal mediation, by defining sub-populations of units according to their compliance behavior and using the information on their friendship networks as mediator. We formally define principal natural direct and indirect effects and principal controlled direct and spillover effects, and use them to disentangle spillovers from other causal channels. We adopt a Bayesian approach for inference.
