MASS MEDIA AND SOCIAL CHANGE: CAN WE USE TELEVISION TO FIGHT POVERTY?
提出一个分析娱乐媒体如何影响发展的框架，涵盖信息提供、角色塑造与偏好改变、时间使用三条渠道，并综述电视和广播对生育、性别规范、教育、移民和社会资本等结果的影响证据。
This paper explores the potential use of entertainment media programs for achieving development goals. I propose a simple framework for interpreting media effects that hinges on three channels: (i) information provision, (ii) role modeling and preference change, and (iii) time use. I then review the existing evidence on how exposure to commercial television and radio affects outcomes such as fertility preferences, gender norms, education, migration, and social capital. I complement these individual country studies with cross-country evidence from Africa and with a more in-depth analysis for Nigeria, using the Demographic Health Surveys. I then consider the potential educational role of entertainment media, starting with a discussion of the psychological underpinnings and then reviewing recent rigorous evaluations of edutainment programs. I conclude by highlighting open questions and avenues for future research.
