教育回报从何而来?教育阶段转换与劳动力市场收益

研究问题
当教育是连续经历多个阶段转换的过程时,某次教育转换的收益有多少直接产生,又有多少通过后续教育进程产生?
方法与思路
作者构建序贯教育转换的因果中介框架,将平均处理效应加性分解为互斥的直接和间接路径,并分析 NLSY97。
材料陈述的贡献
摘要称,分解的特殊性质允许较少限制的识别并覆盖全部因果路径;应用中高中毕业收益主要来自直接劳动力市场回报。
阅读关注点
应核对各路径的反事实定义、互斥与加性分解的推导、识别限制的比较,以及后续教育反事实进展率如何估计。
阅读边界
所给版本为 arXiv 预印本,同行评审与期刊接收未核实;摘要未说明完整识别条件或具体效应数值,应用结论限于所述队列。

原文摘要

Conventional research on educational effects typically either employs a "years of schooling" measure of education, or dichotomizes attainment as a point-in-time treatment. Yet, such a conceptualization of education is misaligned with the sequential process by which individuals make educational transitions. In this paper, I propose a causal mediation framework for the study of educational effects on outcomes such as earnings. The framework considers the effect of a given educational transition as operating indirectly, via progression through subsequent transitions, as well as directly, net of these transitions. I demonstrate that the average treatment effect (ATE) of education can be additively decomposed into mutually exclusive components that capture these direct and indirect effects. The decomposition has several special properties which distinguish it from conventional mediation decompositions of the ATE, properties which facilitate less restrictive identification assumptions as well as identification of all causal paths in the decomposition. An analysis of the returns to high school completion in the NLSY97 cohort suggests that the payoff to a high school degree stems overwhelmingly from its direct labor market returns. Mediation via college attendance, completion and graduate school attendance is small because of individuals' low counterfactual progression rates through these subsequent transitions.
