本文利用全国青年纵向调查提供了关于启蒙计划长期效益的新证据。我比较了参与该计划的不同兄弟姐妹，并控制了各种治疗前协变量。我估计 Head Start 参与者在年轻人成果总结指数上获得了 0.23 个标准差。这缩小了家庭收入中位数和后四分位数儿童之间三分之一的差距，大约是 Perry Preschool 等示范项目的 80%。尽管考试成绩的增长“逐渐消失”，但对弱势儿童的长期影响仍然很大。 （JEL H52、J13、I28、I38）
This paper provides new evidence on the long-term benefits of Head Start using the National Longitudinal Survey of Youth. I compare siblings who differ in their participation in the program, controlling for a variety of pre-treatment covariates. I estimate that Head Start participants gain 0.23 standard deviations on a summary index of young adult outcomes. This closes one-third of the gap between children with median and bottom quartile family income, and is about 80 percent as large as model programs such as Perry Preschool. The long-term impact for disadvantaged children is large despite "fade-out" of test score gains. (JEL H52, J13, I28, I38)
