Welfare properties of restrictions to health care based on cost effectiveness
研究了基于成本效益限制医疗准入的福利性质，发现该措施能提高平均医疗效果，但仅在特定福利函数和医疗效用假设下才最优。
In this note we explore the welfare properties of access restrictions to health care based on cost effectiveness. We show that such instrument can improve the average effectiveness of health care, but it is optimal only under specific assumptions relating to the shape of the welfare function and the utility of health care.
