Abstract：
This study assesses the impact of financial incentives on hygienic latrine ownership by poor/near-poor households in Vietnam. Rural communes were randomly assigned to a control group and three treatment arm groups: (T1) a rebate for households that installed a hygienic latrine; (T2) a financial reward for commune governments if the proportion of hygienic latrines in their commune increased by 30 percentage points; (T3) both a household rebate and a commune reward. We find a strong and positive effect from the household rebate (treatment arms 1 and 3) but an insignificant effect from the commune reward (treatment arm 2) on household ownership of a septic tank latrine. Our analysis provides suggestive evidence that microcredit is a channel through which a rebate encourages the installation of septic tank latrines. We also find that treatment arm 3 increases people\'s knowledge regarding sanitation and the availability of water and soap for handwashing within households.
摘要：
这项研究评估了经济激励措施对越南贫困/近贫困家庭拥有卫生厕所的影响。农村公社被随机分配到对照组和三个治疗组：（T1）为安装卫生厕所的家庭提供回扣；（T2）如果公社中卫生厕所的比例增加30个百分点，则对公社政府的经济奖励；（T3）家庭回扣和公社奖励。我们发现家庭回扣（治疗武器1和3）对化粪池厕所的家庭所有权产生了强烈而积极的影响，但公社奖励（治疗武器2）对化粪池厕所的家庭所有权影响不大。我们的分析提供了暗示性证据，表明小额信贷是退税鼓励安装化粪池厕所的渠道。我们还发现，治疗臂3增加了人们关于卫生和家庭内洗手的水和肥皂的可用性的知识。
