年轻女性的心理健康与人工流产:时变未观测异质性、健康行为和风险决策

研究问题
年轻女性人工流产、风险健康行为与心理健康之间的关联,在控制随年龄变化的未观测异质性后如何变化,能否作因果解释?
方法与思路
作者使用瑞典住院和门诊行政记录及分组固定效应估计,刻画年龄变化的潜在组别轨迹,并建立和估计风险选择理论模型。
材料陈述的贡献
摘要称,控制分组时变异质性后,标准估计中的正关联缩至零;风险行为与心理健康呈共同异质性,模型以自控问题差异解释组间差距。
阅读关注点
核对分组固定效应如何支持因果解释、组数和年龄轨迹的选择,以及自控机制的结构识别与替代解释的区分。
阅读边界
仅据所给 OpenAlex 摘要,因果识别假设与不确定性区间未说明;摘要所称零关联及政策含义不能推广为所有人群均无影响。

原文摘要

In this paper, we provide causal evidence on abortions and risky health behaviors as determinants of mental health development among young women. Using administrative in- and outpatient records from Sweden, we apply a novel grouped fixed-effects estimator proposed by Bonhomme and Manresa (2015) to allow for time-varying unobserved heterogeneity. We show that the positive association obtained from standard estimators shrinks to zero once we control for grouped unobserved heterogeneity that varies across ages. We estimate the group profiles of unobserved heterogeneity, which reflect differences in unobserved risk to be diagnosed with a mental health condition. In addition, we analyze mental health development and risky health behaviors other than unintended pregnancies across groups. Our results suggest that these are determined by the same type of unobserved heterogeneity, which we attribute to the same unobserved process of decision-making. We develop and estimate a theoretical model of risky choices and mental health that is consistent with our empirical results. In the model, mental health disparity across groups is generated by different degrees of self-control problems. Our findings imply that mental health concerns cannot be used to justify restrictive abortion policies.
