The political economy of public health expenditure and wait times in a public‐private mixed health care system
研究了公私混合医疗体系中公共卫生支出的决定因素，发现均衡支出和等待时间取决于人口结构，而与收入分配和政治影响力分布无关，且人口老龄化不一定导致公共卫生支出增加。
Abstract This paper investigates the determinants of public health expenditure in a public‐private mixed health care system, where a longer wait time for public care is the major difference between public and private sectors. Voter preferences for health care vary according to their age and by income, and public policy choices are part of a multi‐dimensional, competitive political equilibrium. We show how equilibrium public health expenditure and wait times depend on demographics and explain why they are independent of the distributions of income and political influence. We also show that population aging may not always lead to more public health expenditure.
