This paper investigates long-term home care utilization in Europe. Data from the first wave of the Survey on Health, Ageing and Retirement (SHARE) on formal (nursing care and paid domestic help) and informal care (support provided by relatives) are used to study the probability and the quantity of both types of care. The overall process is framed in a fully simultaneous equation system that takes the form of a bivariate two-part model where the reciprocal interaction between formal and informal care is estimated. Endogeneity and unobservable heterogeneity are addressed using a common latent factor approach. The analysis of the relative impact of age and disability on home care utilization is enriched by the use of a proximity to death (PtD) indicator built using the second wave of SHARE. All these indicators are important predictors of home care utilization. In particular, a strong significant effect of PtD is found in the paid domestic help and informal care models. The relationship between formal and informal care moves from substitutability to complementarity depending on the type of care considered, and the estimated effects are small in absolute size. This might call for a reconsideration of the effectiveness of incentives for informal care as instruments to reduce public expenditure for home care services.
本文研究了欧洲长期家庭护理的使用情况。来自健康、老龄化与退休调查(SHARE)第一波的正式护理(护理服务和付费家政服务)和非正式护理(亲属提供的支持)数据,用于研究这两种护理方式的使用概率和使用量。整个过程构建在一个完全联立方程系统中,该系统采用二元两部分模型的形式,用于估计正式护理和非正式护理之间的相互作用。使用共同潜在因素方法解决内生性和不可观测的异质性问题。通过使用基于SHARE第二波构建的接近死亡(PtD)指标,丰富了对年龄和残疾对家庭护理使用的相对影响的分析。所有这些指标都是家庭护理使用的重要预测因素。特别是,在付费家政服务和非正式护理模型中发现了PtD的强烈显著影响。根据所考虑的护理类型,正式护理和非正式护理之间的关系从可替代性转变为互补性,且估计效应的绝对值较小。这可能需要重新考虑将非正式护理激励措施作为减少家庭护理服务公共支出的手段的有效性。
