本文探讨了两个最古老和最广泛引用的美国早期儿童干预措施的长期影响，通过随机化和长期随访的方法进行评估：佩里学前项目（PPP）和卡罗莱纳初学者项目（ABC）。有明显的性别效应，对男孩非常有利，尽管对女孩也有影响。动态中介分析显示，改善童年特征发挥了重要作用，超出了实验增强成人社会经济地位的影响。这些结果显示了生命早期干预促进健康的潜力。伦敦大学学院应用卫生研究系伦敦托灵顿广场1-19号WC 1 E 7 HB英国gabriella. ucl.ac.uk詹姆斯J.赫克曼经济系芝加哥大学1126 E。第59街芝加哥，IL 60637和IZA以及NBER jjh@uchicago.edu罗德里戈平托经济系芝加哥大学1126 E。59 th Street芝加哥，IL 60637 rodrig@uchicago.edu在线附录可在http://www.nber.org/data-appendix/w21454获得
This paper examines the long-term impacts on health and healthy behaviors of two of the oldest and most widely cited U.S. early childhood interventions evaluated by the method of randomization with long-term follow-up: the Perry Preschool Project (PPP) and the Carolina Abecedarian Project (ABC). There are pronounced gender effects strongly favoring boys, although there are also effects for girls. Dynamic mediation analyses show a significant role played by improved childhood traits, above and beyond the effects of experimentally enhanced adult socioeconomic status. These results show the potential of early life interventions for promoting health.
