健康保险对医疗服务利用的因果关系存在很大的不确定性。我们利用保险覆盖率的急剧变化，这是由于年轻人的父母的保险计划“老化”造成的，以估计保险覆盖率对急诊科（ED）和住院服务的利用的影响。老龄化导致拥有健康保险的概率突然下降5到8个百分点。我们发现，无保险状态导致急诊科就诊减少40%，住院住院减少61%。（j22, i11, i18）
Substantial uncertainty exists regarding the causal effect of health insurance on the utilization of care. We exploit a sharp change in insurance coverage rates that results from young adults "aging out" of their parents' insurance plans to estimate the effect of insurance coverage on the utilization of emergency department (ED) and inpatient services. Aging out results in an abrupt 5 to 8 percentage point reduction in the probability of having health insurance. We find that uninsured status leads to a 40 percent reduction in ED visits and a 61 percent reduction in inpatient hospital admissions. (JEL G22, I11, I18)
