July 2020Labor Market Screening and Social Insurance Program Design for the Disabled
with Naoki Aizawa, Serena Rhee: w27478
This paper studies the optimal design of social insurance programs for disabled workers by developing and estimating an equilibrium labor search model with screening contracts. In the model, firms may strategically use employment contracts, consisting of wage and job amenities, to screen out the disabled. The optimal structure of disability policies depends on firms' screening incentives, which may distort employment rates and contracts. By exploiting policy changes on the labor demand side for the disabled in the United States, we identify and estimate our equilibrium model to explore the optimal joint design of disability policies, including disability insurance (DI) and subsidies to firms accommodating disabled workers. We find that firm subsidies mitigate screening distortions; at the ...
November 2012Analyzing the Effects of Insuring Health Risks: On the Trade-off between Short Run Insurance Benefits vs. Long Run Incentive Costs
with Harold L. Cole, Dirk Krueger: w18572
This paper constructs a dynamic model of health insurance to evaluate the short- and long run effects of policies that prevent firms from conditioning wages on health conditions of their workers, and that prevent health insurance companies from charging individuals with adverse health conditions higher insurance premia. Our study is motivated by recent US legislation that has tightened regulations on wage discrimination against workers with poorer health status (Americans with Disability Act of 2009, ADA, and ADA Amendments Act of 2008, ADAAA) and that will prohibit health insurance companies from charging different premiums for workers of different health status starting in 2014 (Patient Protection and Affordable Care Act, PPACA). In the model, a trade-off arises between the static gains ...
