Evidence of Adverse Selection in Automobile Insurance Markets


  • Dionne, G.
  • Gourieroux, C.
  • Vanasse, C.


In this paper, we propose an empirical analysis of the presence of adverse selection in an insurance market. We first present a theroetical model of a market with adverse selection and we introduce different issues related to transaction costs, accident costs, risk aversion and moral hazard. We then discuss an econometric modeling based on latent variables and we derive its relationship with specification in the portfolio of an insurer.
