L’effet de la Couverture maladie universelle complémentaire (CMU-C) sur le nombre de visites chez le médecin : une analyse par régression sur discontinuités

This paper assesses the impact of a free means-tested complementary health insurance on doctor visits. In order to tackle the endogeneity issue of the complementary health insurance variable, we use information on the selection rule to qualify for the free plan and adopt a regression discontinuity approach using eligibility (family income below the cut-off value) as an instrument variable. Findings show a significant effect of the free plan on the number of doctor visits, especially on the number of general practitioner visits. However, we do not find any impact on the likelihood of seeing a doctor.
