Little is known about the price sensitivity of demand for home care of the disabled elderly. We partially fill this knowledge gap by using administrative data on the beneficiaries of the main French home care subsidy program in a department and exploiting interindividual variation in provider prices. We address the potential endogeneity of prices by taking advantage of the unequal spatial coverage of providers and instrumenting price by the number of municipalities served by a provider. We estimate a price elasticity of around -0.4 that is significantly different from both 0 and -1. This less than proportionate response of consumption to price has implications for the efficiency and redistributive impact of variation in the level of copayments in home care subsidy schemes.
对于残疾老年人家庭护理需求的价格敏感性，我们知之甚少。我们利用某一部门内法国主要家庭护理补贴计划受益人的行政数据，并利用供应商价格的个体差异，部分填补了这一知识空白。我们通过利用供应商在空间覆盖范围上的不平等，并以供应商服务的市政数量作为价格的工具变量，来解决价格的潜在内生性问题。我们估计价格弹性约为-0.4，这与0和-1均有显著差异。消费对价格的这种小于成比例的反应，对家庭护理补贴计划中自付费用水平变化的效率和再分配影响具有启示意义。
