The effects of access to health insurance: Evidence from a regression discontinuity design in Peru
利用秘鲁2000年代初的制度改革形成的断点，研究获得医疗保险对医疗服务利用的影响，发现对治疗性护理有显著促进作用，并引发患者自费购买短缺服务。
In many countries large parts of the population do not have access to health insurance. Peru has made an effort to change this in the early 2000s. The institutional setup gives rise to the rare opportunity to study the effects of health insurance coverage exploiting a sharp regression discontinuity design. We find large effects on utilization that are most pronounced for the provision of curative care. Individuals seeing a doctor leads to increased awareness about health problems and generates a potentially desirable form of supplier-induced demand: they decide to pay themselves for services that are in short supply.
