Micro-econometric analysis of care for the dependent elderly in France : How do formal and informal care interact ?
Résumé
This paper focuses on the trade-off between formal care and informal care for disabled elderly people living in the community. We propose a simple microeconomic model which describes the simultaneous decision process between potential informal caregivers and disabled elderly person
living at home. The model predicts a strict substitution between the two kinds of care. To test the substitution e ffect and assess its intensity, we estimate a recursive simultaneous equation model linked by a copula function, using data from the French\ Handicap Santé Ménages " survey (2008). In contrast with previous literature, the estimated model allows to simultaneously identify both potential causality directions. Thanks to the
copula function, strong assumptions about a linear link between the two residuals of both equations do not have to be made. Our results con firm that informal and formal home care are globally substitutes. Nevertheless, the predicted increase of formal care following a reduction of one hour of informal care remains very small. Informal care supply is also weakly sensitive to variations of formal care hours: The substitution e ffect is high only for individuals receiving much more informal than formal care.
