监禁的健康效应

The Health Effects of Prison
American Economic Journal: Applied Economics · 2022 · Randi Hjalmarsson、Matthew J. Lindquist

中文摘要

本文研究了瑞典监狱改革的健康效应。这些改革保持刑期不变,但提高了囚犯必须实际服刑的时间占刑期的比例。实际服刑时间延长并未损害出狱后的健康状况,反而降低了死亡风险。我们发现,此前未被监禁过的罪犯、较年轻的罪犯以及与劳动力市场联系更紧密的罪犯,其死亡率下降幅度尤其大。有心理健康问题的囚犯自杀风险下降,而年长囚犯的循环系统疾病死亡风险下降。随着实际服刑时间延长,狱中医疗服务利用和项目参与均有所增加,提示医疗保健治疗和服务是死亡率下降的关键机制。

Abstract

This paper studies the health effects of Swedish prison reforms that held sentences constant but increased the share of time inmates had to serve. The increased time served did not harm post-release health and actually reduced mortality risk. We find especially large decreases in mortality for offenders not previously incarcerated, younger offenders, and those more attached to the labor market. Risk of suicide and circulatory death fell for inmates with mental health problems and older inmates, respectively. In-prison health care utilization and program participation increased with time served, suggesting health care treatment and services as the key mechanism for mortality declines. (JEL I12, I18, K42)
