Social Support Substitution and the Earnings Rebound: Evidence from a Regression Discontinuity in Disability Insurance Reform
利用荷兰残疾人保险改革中队列断点，研究发现现有受益人在福利减少后，通过增加其他社会救助和提升收入来弥补损失，表明长期领取者仍有显著收入能力。
We exploit a cohort discontinuity in the stringency of Dutch disability reforms to estimate the effects of decreased DI (disability insurance) generosity on behavior of existing recipients. We find evidence of social support substitution: individuals on average offset €1.00 of lost DI benefits by collecting €0.30 more from other social assistance programs, but this benefit-substitution effect declines over time. Individuals also exhibit a rebound in earnings: earnings increase by € 0.62 on average per euro of lost DI benefits and this effect remains roughly constant over time. This is strong evidence of substantial remaining earnings capacity among long-term claimants of DI.
