Causes of regional variation in Dutch healthcare expenditures: Evidence from movers
利用2006-2013年荷兰全部人口的年度医疗支出数据，通过追踪跨区域迁移者，发现地区医疗支出差异约70%由需求因素驱动，供给因素影响较小。
We assess the relative importance of demand and supply factors as determinants of regional variation in healthcare expenditures in the Netherlands. Our empirical approach follows individuals who migrate between regions. We use individual data on annual healthcare expenditures for the entire Dutch population between the years 2006 and 2013. Regional variation in healthcare expenditures is mostly driven by demand factors, with an estimated share of around 70%. The relative importance of different causes varies with the groups of regions being compared.
