Travail de recherche/Working paper
Résumé : In the paper I criticize the neglect by the theory of equality of opportunities of the issue of ex-post moral hazard. I discuss of the three components of ex-post moral hazard: the first is the usual overconsumption due to a low or zero price, the second is a psychological component, leading to increased consumption if the illness was not generated by ex-ante moral hazard, and the third is the wrong/excess consumption due to the desire of reducing the time cost of services use.I illustrate the bias implicit in the theory of equality of opportunities due to the omission of ex-post moral-hazard and I show that stigmatizing ex-ante moral-hazard without doing the same for ex-post moral hazard is unfair.
