Incentive Effects of Disability Benefits [Link]
with Sebastian Becker, Johannes Geyer, and Peter Haan - R&R at Journal of Labor Economics
We provide novel evidence on the trade-off between insurance and incentives when adjusting disability insurance (DI) benefit generosity using a comprehensive measure that encompasses not only the effect on take-up but also behavioral responses of DI recipients with respect to employment and exit from DI. Based on administrative data from the German pension insurance and exogenous policy variation, we identify the relevant behavioral margins induced by a change in benefit generosity. Using a theoretical framework, we show that our comprehensive measure of incentive effects implies a fiscal multiplier of 1.83. Incorporating elasticities with respect to exit from DI increases the fiscal multiplier compared to estimates that only account for take-up elasticities. In the context of the model, we estimate that increasing benefits is welfare improving, given the insurance effects of DI benefits estimated in previous literature.
Occupations, Disability Insurance, and Career Choices [Draft available upon request]
Work-limiting disabilities pose a significant risk to the earnings potential and welfare of older workers. While coverage of public disability insurance (DI) systems is almost universal, the risk of becoming dependent on DI varies across occupations. In this paper, I study the value of public DI across different occupations using data from administrative social security records in Germany. I evaluate how public DI coverage affects long-run labor market outcomes by analyzing the employment effects of a large-scale policy reform that eliminated occupational DI coverage in Germany. I find that the reform increased earnings but reduced full-time employment, primarily through a decline in manual jobs. I then use a structural model to study the relationship between disability insurance, occupational choice, and retirement in a life-cycle context. In counterfactual experiments, I evaluate how adjustments to the DI and retirement system affect the labor supply of different occupational groups.
