Second generation effects of an experimental conditional cash transfer program on early childhood human capital in Nicaragua
研究尼加拉瓜有条件现金转移支付项目受益者的子女（0-3岁）在营养、认知等方面的表现，发现母亲教育提升未带来儿童改善，反而与母亲心理健康恶化及暴力管教增加相关。
Interventions targeting improvements in human capital are often motivated by their potential to break the intergenerational transmission of poverty from parents to children. This study contributes to the thin evidence base on these links by examining outcomes for children of former program beneficiaries of a conditional cash transfer (CCT) program, capitalizing on randomized variation in the timing and CCT's impact on maternal human capital. We estimate intent-to-treat (ITT) differential effects on early childhood anthropometric and cognitive outcomes for 0-3-year-old children of program beneficiaries [N=366], as well as effects on key domains including nutrition, health, stimulation and the home environment. We find that moderately higher schooling for mothers (19-22 years old) who were the original program beneficiaries did not translate into improvements in anthropometrics or cognitive outcomes for their children. We also find no effects on behaviors commonly thought to be affected by higher education such as investments in nutrition and preventive health, or stimulation. Early program beneficiary mothers, however, had worse mental health outcomes and were more likely to use violent disciplinary practices such as spanking, threatening and punishing. Findings demonstrate the complexity of intergenerational mechanisms across genetic, biological, environmental and behavioral factors, and also suggest the importance of maternal mental health as a mechanism influencing child outcomes.
