论文摘要
世界各地的媒体在国家一级以及地方一级都被传播。尽管媒体塑造偏好和行为的能力已得到广泛认可，但对当地媒体的差异影响知之甚少。由于提供了社区中常识的本地相关信息，因此本地媒体可能对社会规范具有特别重要的影响。我在高风险的情况下检查了这种可能性：几内亚的埃博拉病毒流行。我利用了访问不同媒体的访问和社区广播中公共卫生活动的时机的准随机变化。我发现，如果可以使用邻近社区广播电台的地方拥有自己的埃博拉病例，则可以预防埃博拉病例。这是由广播电台的所在地，而不是民族语言界限的驱动，也是由当地认可的社会行为协调所驱动的。
Media around the world is disseminated at the national level as well as at the local level. While the capacity of media to shape preferences and behavior has been widely recognized, less is known about the differential impacts of local media. Local media may have particularly important effects on social norms due to the provision of locally relevant information that becomes common knowledge in a community. I examine this possibility in a high-stakes context: the Ebola epidemic in Guinea. I exploit quasi-random variation in access to distinct media outlets and the timing of a public-health campaign on community radio. I find that 13% of Ebola cases would have been prevented if places with access to neighboring community radio stations had instead their own. This is driven by radio stations' locality, not ethno-linguistic boundaries, and by coordination in social behaviors sanctioned locally.
