Basic versus supplementary health insurance: moral hazard and adverse selection

Author

  • Boone, Jan
Abstract
This paper introduces a tractable model of health insurance with both moral hazard and adverse selection. We show that government sponsored universal basic insurance should cover treatments with the biggest adverse selection problems. Treatments not covered by basic insurance can be covered on the private supplementary insurance market. Surprisingly, the cost effectiveness of a treatment does not affect its priority to be covered by basic insurance.
