领取残障保险对死亡率的影响

中文摘要

本文估计了领取残障保险和补充保障收入对处于获准与被拒福利临界状态个人的死亡率的影响。利用行政法法官对残障保险案件的随机分派，我们发现获准领取福利使边际受益人的10年死亡率提高2.8个百分点。然而，运用边际处理效应方法，我们发现有证据表明，领取福利会降低边际内受益人的死亡率，而这类受益人的健康状况通常比边际受益人更差。此外，我们还发现提示性证据表明，获准领取福利会降低患有癌症等治疗费用高昂疾病人群的死亡率。

Abstract

This paper estimates the effect of Disability Insurance and Supplemental Security Income receipt on mortality for individuals on the margin of being allowed versus denied benefits. Exploiting the random assignment of administrative law judges to disability insurance cases, we find that benefit allowance increases 10-year mortality rates by 2.8 percentage points for marginal beneficiaries. However, using a Marginal Treatment Effects approach, we find evidence that benefit receipt reduces mortality for inframarginal beneficiaries, who are typically less healthy than marginal beneficiaries. Furthermore, we find suggestive evidence that allowance reduces mortality among those with expensive health conditions such as cancer.
