Does Disability Insurance Receipt Discourage Work? Using Examiner Assignment to Estimate Causal Effects of SSDI Receipt
利用行政数据和审查员批准率差异，估计社会保障伤残保险领取对劳动力供给的因果效应，发现边缘申请人若未领取福利，就业率会高28个百分点。
We present the first causal estimates of the effect of Social Security Disability Insurance benefit receipt on labor supply using all program applicants. We use administrative data to match applications to disability examiners and exploit variation in examiners' allowance rates as an instrument for benefit receipt. We find that among the estimated 23 percent of applicants on the margin of program entry, employment would have been 28 percentage points higher had they not received benefits. The effect is heterogeneous, ranging from no effect for those with more severe impairments to 50 percentage points for entrants with relatively less severe impairments.
