题目：The Health Care Safety Net and Health Insurance: A Theoretical and Empirical Investigation
工作语言：中文/英文
文章摘要（全文请见附件）
The large and growing uninsured population poses an alarming threat to the U.S. health care system. This paper explores one of the less cited causes of the lack of health insurance: the health care safety net. We showed that not purchasing insurance can be a rational decision reflecting the various alternatives to the option, and the safety net policy, despite its good intention, inevitably creates an insurance alternative that crowds out private coverage in the market setting. We extended Ehrlich and Becker (1972) to incorporate the safety net alternative in the model of demand for health insurance. We showed that the existence of such free remedial resources produces a direct disincentive to the purchase of market insurance of health, a pattern we called the “safety net moral hazard”. Our calibrated simulation indicates about 15.75% of the current uninsured population, or 7.2 million people in U.S., can attribute their lack of health insurance to the existing safety net system. Our empirical model verifies the crowding-out effect with significant and robust evidence. On average, the presence of local safety net resources can reduce the probability of individual insurance purchase by as much as 3.55%.
