Entertainment-Education for Better Health: Insights from a Field Experiment in India
通过印度田野实验，发现健康娱乐教育（如电影）能提升健康知识16%，效果持续近一年，但对健康行为无显著影响，且经济激励未增强效果。
Entertainment-education has been touted as a potent delivery channel for health education campaigns. Yet, there is little evidence of its causal effects. This paper aims to fill the gap in the literature by using a field experiment in India to study two questions on the efficacy of health entertainment-education. First, can health entertainment-education, particularly through films that show role models and draw on emotions, lead to lasting, positive change in health knowledge and behavior? Second, can financial incentives for ex-post health literacy boost the effectiveness of health entertainment-education? The results show that health entertainment-education successfully increased health knowledge (e.g. knowledge about cleanliness and hygiene) by 16 percent. These gains persist almost one year later, although there were no observed impacts on health behaviors. Further, financial incentives do not appear to have any effects. These insights contribute to our knowledge of what works for health education in low-income settings, so that future education campaigns can be crafted with more meaningful impact.
