We investigate the effect of Head Start on education and wage income for individuals in their 30s in the NLSY79. We contribute to the existing literature by examining effects across outcome distributions, using an approach that relies on two weak stochastic dominance assumptions that can be checked using pre–Head Start cohorts. We find that Head Start has positive and statistically significant effects on years of education and wage income. We also uncover important heterogeneity in the program’s effectiveness; the effects are concentrated at the lower end of the distribution, and the effects are strongest for women, blacks, and Hispanics.

领先的开始以及长期教育和劳动力市场成果的分配

我们在NLSY79中调查了创业初期对30多岁个人的教育和工资收入的影响。我们使用依赖于两个弱随机随机性假设的方法来检查结果分布的影响，从而为现有文献做出贡献，该假设可以使用“先启蒙”队列进行检验。我们发现，Head Start对受教育年限和工资收入具有积极的和统计学上显着的影响。我们还发现了程序有效性方面的重要异质性；影响集中在分布的较低端，对女性，黑人和西班牙裔人的影响最大。
