反事实斜率及其在社会分层研究中的应用

研究问题
教育转衔中的差异性选择可能扭曲社会经济地位与结果的关联,如何在消除该选择的假想干预下检验两项社会分层论题?
方法与思路
作者定义反事实斜率这一非参数因果目标,并基于有效影响函数构造灵活、有效率且稳健的估计量,应用于美国代表性数据。
材料陈述的贡献
摘要称该框架提供排除差异性选择的检验;应用认为描述规律会误导教育大均衡器论题的实质解释,但未同样误导学校转衔论题。
阅读关注点
应核对消除选择的干预如何定义、反事实斜率的识别条件和稳健性含义,以及应用结论对协变量选择及模型设定的敏感性。
阅读边界
这是 arXiv 预印本,不能据此认定已同行评审或获期刊接收;摘要未列出识别假设、数据细节或效应数值,应用结论尚需核对。

原文摘要

This paper addresses two prominent theses in social stratification research, the great equalizer thesis and Mare's (1980) school transition thesis. Both theses describe the role of an intermediate educational transition in the association between socioeconomic status and an outcome variable. However, the descriptive regularities of the two theses may be driven by differential selection into the intermediate transition, which prevents the two theses from having substantive interpretations. We propose a set of novel counterfactual slope estimands, which capture these theses under hypothetical interventions that eliminate the differential selection. We thereby construct selection-free tests for these theses. Compared with the existing literature, we are the first to explicitly provide nonparametric causal estimands, which enable us to conduct more principled analysis. We are also the first to develop flexible, efficient, and robust estimators for the two theses based on efficient influence functions. We apply our framework to a nationally representative dataset in the United States and re-evaluate the two theses. Findings from our selection-free tests suggest that the descriptive regularities are misleading for the substantive interpretation of the great equalizer thesis, but not for that of the school transition thesis. Additionally, the counterfactual slopes also provide a new framework for evaluating the inequality impacts of policy interventions.
