Health Insurance and Consumption Risk
研究健康保险如何与收入等其他风险相互作用，影响美国家庭的消费风险，发现标准合同会放大其他风险的影响，而限制自付支出与收入比例的替代合同能提供更好的风险保护。
Abstract The effect of health insurance on consumption risk depends in part on how it interacts with other risks beyond health care cost risk, such as income risk. Using a variety of approaches, I find that for U.S. households, the interaction with other risks transforms the risk protection from health insurance. Standard contracts amplify the impact of other risks, due to both subsidizing normal goods and undoing the protection against other risks from discounts, charity care, and bad debt. Alternative contracts that account for other risks, such as contracts that limit out-of-pocket spending relative to income, can provide better risk protection.
