Retiree Health Insurance and the Labor Force Behavior of Older Men in the 1990s
利用健康与退休调查数据，发现雇主提供的退休健康保险使51-62岁男性每年退出就业的比率提高2到6个百分点，且影响随年龄增长，到61岁时达9个百分点。
We estimate the impact of employer-provided retiree health insurance on the rate at which men aged 51-62 enter and exit the labor force and switch jobs. The models estimated are an approximation of the employment decision rules implied by a dynamic stochastic model of employment behavior of older individuals. We use data from the Health and Retirement Survey (HRS), which contains more detailed and accurate measures of retiree health insurance than those used in most previous studies. The results show that availability of employer-provided retiree health insurance (EPRHI) increases the rate of exit from employment by two percentage points per year on average if the individual shares the cost of the insurance coverage with the firm, and by six percentage points if the firm pays the entire cost. The impact of EPRHI on the annual rate of labor force exit increases with age, reaching nine percentage points by age 61. These are larger than the effects estimated in previous studies. The accurate and detailed health insurance measures available in the HRS help account for the larger effects found here. Controlling for unobserved heterogeneity, a possibility not accounted for in previous studies, also has a substantial impact on the estimates. (orig.)
