L'accès aux soins des populations modestes en France : études micro-économétriques des comportements de recours à la complémentaire santé et aux soins

The purpose of this research is to study the financial access to complementary health insurance (CHI) and to health care of low-income populations in France. We are particularly interested in evaluating a subsidized health insurance program (ACS) introduced to encourage households whose resources are just above the free means-tested complementary health insurance program (CMUC), to purchase a CHI plan. In implementing a randomized experiment and in using a sample of eligible households for these programs, we are able to enhance the knowledge base on three issues: (i) Understanding and reducing the ACS non-take-up. (ii) The take-up of CHI plan and the health care use of low-income populations. (iii) The existence of a CMUC threshold effect. Results of this thesis provide some important tracks to improve the effectiveness of these programs and more generally that of future public policies aiming to improve equity in access to health care.
