Federalism and regional health care expenditures: an empirical analysis for the Swiss cantons
利用瑞士26个州的数据，分析经济、人口和结构因素对人均医疗支出的影响，发现老年人口比例和按服务收费的医生会推高医疗成本，提示可能存在供给诱导需求。
Switzerland (7.2 million inhabitants) is a federal state composed of 26 cantons. The autonomy of cantons and a particular health insurance system create strong heterogeneity in terms of regulation and organisation of health care services. In this study we use a single-equation approach to model the per capita cantonal expenditures on health care services and postulate that per capita health expenditures depend on some economic, demographic and structural factors. The empirical analysis demonstrates that a larger share of old people tends to increase health costs and that physicians paid on a fee-for-service basis swell expenditures, thus highlighting a possible phenomenon of supply-induced demand.
