Efforts to control medical care costs depend critically on how individuals respond to prices. I estimate the price elasticity of expenditure on medical care using a censored quantile instrumental variable (CQIV) estimator. CQIV allows estimates to vary across the conditional expenditure distribution, relaxes traditional censored model assumptions, and addresses endogeneity with an instrumental variable. My instrumental variable strategy uses a family member's injury to induce variation in an individual's own price. Across the conditional deciles of the expenditure distribution, I find elasticities that vary from -0.76 to -1.49, which are an order of magnitude larger than previous estimates.

卫生保健支出价格弹性的删减分位数工具变量估计。

控制医疗费用的努力主要取决于个人对价格的反应。我使用审查的分位数工具变量（CQIV）估算器估算了医疗保健支出的价格弹性。CQIV允许估算值随条件支出分布而变化，放宽传统的审查模型假设，并通过工具变量解决内生性。我的工具可变策略使用家庭成员的伤害来诱使个人自身价格发生变化。在支出分配的条件十分位数中，我发现弹性从-0.76到-1.49不等，比以前的估计大一个数量级。
