摘要

一项为期18个月的随机试验数据显示，向有幼儿的家庭每月提供免费水处理解决方案优惠券的项目对水净化和儿童健康产生了巨大而持久的影响。该计划比要求社区卫生工作者在每月例行访问期间向家庭分发免费氯气更有效，成本效益也高得多。这是因为只有40%的家庭使用游离氯，通过卫生保健中心的目标比通过优惠券兑换的自我目标更差，而且卫生保健中心的水处理推广并没有增加游离氯受益者的氯使用量。(jel i12, i18, j13, o12, o13, q53)

Expanding Access to Clean Water for the Rural Poor: Experimental Evidence from Malawi

Data from an 18-month randomized trial show large and sustained impacts on water purification and child health of a program providing monthly coupons for free water treatment solution to households with young children. The program is more effective and much more cost effective than asking Community Health Workers (CHWs) to distribute free chlorine to households during routine monthly visits. This is because only 40 percent of households use free chlorine, targeting through CHWs is worse than self-targeting through coupon redemption, and water treatment promotion by CHWs does not increase chlorine use among beneficiaries of free chlorine. (JEL I12, I18, J13, O12, O13, Q53)
