Parental investment, school choice, and the persistent benefits of an early childhood intervention
基于随机实验，研究六个月家访项目对儿童入学时父母投资和学校选择的持续影响，发现项目提高了家庭投资、学前入学率和质量偏好，并改善了儿童工作记忆。
We present evidence from a randomised experiment testing the impacts of a six-month early childhood home-visiting program on child outcomes and parental investment behaviour at school entry. Two and a half years after completion of the program, we find large persistent effects on parental investment at home, as well as large effects on preschool enrolment. Children in treatment villages were enrolled earlier and in higher quality preschools, the latter reflecting a shift in preferences over preschool attributes towards quality. Finally, we find evidence that the program increased child working memory, but do not find strong evidence of impacts on other cognitive sub-domains or on non-cognitive skills of children at school entry.
