俄勒冈州健康保险实验的一个主要结果是急诊室(ER)的利用率增加了。马萨诸塞州卫生改革的一个看似矛盾的结果是ER利用率下降。我通过识别俄勒冈州实验中的治疗效果异质性并将其外推至马萨诸塞州来调和这两个结果。即使俄勒冈州的遵守者增加了他们的ER利用率,他们被不利地选择相对于俄勒冈州从来没有采取者,谁会减少他们的ER利用率。马萨诸塞州将覆盖范围从更高的水平扩大到更健康的遵守者。因此,马萨诸塞州的顺从者可以与俄勒冈州的一个子集相媲美,这可以调和结果。
A headline result from the Oregon Health Insurance Experiment is that emergency room (ER) utilization increased. A seemingly contradictory result from the Massachusetts health reform is that ER utilization decreased. I reconcile both results by identifying treatment effect heterogeneity within the Oregon experiment and extrapolating it to Massachusetts. Even though Oregon compliers increased their ER utilization, they were adversely selected relative to Oregon never takers, who would have decreased their ER utilization. Massachusetts expanded coverage from a higher level to healthier compliers. Therefore, Massachusetts compliers are comparable to a subset of Oregon never takers, which can reconcile the results.
