Employment-based health insurance and aggregate labor supply
通过一般均衡生命周期模型，研究美国就业型健康保险制度对就业率、全职兼职比例和总工时的影响，发现该制度为美国人提供了额外的工作激励，并能解释美欧劳动市场差异。
We study the impact of the U.S. employment-based health insurance system on the employment rate, the shares of full-time/part-time workers, and aggregate hours worked in a general equilibrium life cycle model with incomplete markets and idiosyncratic risks in both income and medical expenses. In contrast to most Europeans, who get universal health insurance from the government, most working-age Americans get health insurance through their employers. We find that the employment-based health insurance system provides Americans with an extra incentive to work and work full-time. In a calibrated version of the model, we assess the extent to which the different health insurance systems account for the differences in employment rate and full-time/part-time shares of workers between the U.S. and European countries. Our quantitative results suggest that the different health insurance systems can account for a significant fraction of the differences in employment rate and full-time/part-time shares of workers between the two regions. In addition, we find that the employment-based health insurance system is one of the reasons why many Americans work more than Europeans.
