英文摘要:
We study the effectiveness of a community-level information intervention aimed at improving sanitation using a cluster-randomized controlled trial (RCT) in Nigerian communities. The intervention, Community-Led Total Sanitation (CLTS), is currently part of national sanitation policy in more than 25 countries. While average impacts are exiguous almost three years after implementation at scale, the results hide important heterogeneity: the intervention has strong and lasting effects on sanitation practices in poorer communities. These are realized through increased sanitation investments. We show that community wealth, widely available in secondary data, is a key statistic for effective intervention targeting. Using data from five other similar randomized interventions in various contexts, we find that community-level wealth heterogeneity can rationalize the wide range of impact estimates in the literature. This exercise provides plausible external validity to our findings, with implications for intervention scale-up. JEL Codes: O12, I12, I15, I18.

中文摘要:
我们通过在尼日利亚社区进行的分组随机对照试验(RCT),研究了旨在改善卫生条件的社区级信息干预的有效性。社区主导的全面环境卫生(CLTS)干预目前是25多个国家国家环境卫生政策的一部分。虽然在大规模实施近三年后,平均影响很小,但结果隐藏了重要的异质性:干预措施对较贫穷社区的卫生实践产生了强烈而持久的影响。这些都是通过增加卫生投资来实现的。我们表明,二手数据中广泛存在的社区财富是有效干预目标的关键统计数据。利用其他五种类似随机干预措施在不同背景下的数据,我们发现社区层面的财富异质性可以使文献中广泛的影响估计合理化。这一实践为我们的研究结果提供了合理的外部有效性,并对干预规模的扩大产生了影响。JEL代码:O12、I12、I15、I18。
