The impact of a mandatory universal drug insurance program on health behaviors and outcomes
利用加拿大纵向数据，研究了在免费医疗体系下强制全民处方药保险对健康的影响，发现该政策改善了总体健康、降低了体重指数和吸烟率，但增加了饮酒量，对心理健康、体力活动和预防性护理无显著影响，并缩小了基于社会经济地位的健康差距。
This paper investigates the effects of a mandatory, universal prescription drug insurance policy on health behaviors and outcomes within a public health care system providing physician and hospital services free of charge. Using Canadian longitudinal data, we show that the reform improved individuals' general health while reducing body mass index and smoking. However, the program also increased drinking and had no significant impact on mental health, physical activity, or preventive care. We also examine the mechanisms through which these effects can play a role, as well as the heterogeneous effects. Estimates suggest that the policy decreased SES-based disparities in health.
