Abstract

In this article, we study the optimal level of prevention in the face of an uncertainty on the health status. We analyze the individual choices of primary prevention and secondary prevention when the probability of appearance of the disease is not perfectly known. In order to distinguish the risk aversion and the ambiguity aversion, we use the representation model of preferences proposed by Klibanoff, Marinacci and Mukerji [2005]. We show that the ambiguity aversion incites individuals to make more primary and secondary prevention when the marginal utility of wealth is an increasing function of health status. Classification JEL : D91, I12, I18.
