中文摘要

本文评估了尼加拉瓜城市贫困地区一项面向0–4岁儿童的公共托育项目。我们的识别策略利用该项目在社区层面的随机分配所产生的外生变异,处理对最初处理分配的不完全依从问题。我们发现,该项目使儿童的社会情感技能提高了0.38个标准差,并使母亲从事工作的比例提高了12个百分点,这使该项目具有很高的成本效益。我们未发现该项目的影响因已观测或未观测到的家庭特征而存在较大差异的证据,并提供了提示性证据,表明托育中心质量对产生正向影响具有重要作用。

Abstract

This paper evaluates a public childcare program for children ages 0–4 in poor urban areas in Nicaragua. Our identification strategy exploits the program’s neighborhood-level randomization as exogenous variation to tackle imperfect compliance with the original treatment assignments. We find a positive impact of 0.38 standard deviations on socio-emotional skills and a 12-percentage-point increase on mothers’ work, which makes the program highly cost-effective. We do not find evidence of substantial heterogeneity of impacts across observed or unobserved household characteristics, and we present suggestive evidence of the importance of center quality for generating positive impacts.
