Further, let Tr be the premium paid by the insured while q is the level of coverage. In case ofa claim (such as falling ill) the cost is L > q. Thus, if p(x) is the probability of falling ill which is a function of x -the care level, then the expected utility for the insured is : Eu = [1- p(x)]u(w-1t -x) + p(x)u(w-1t -x - L +q) Maximization of the expected utility leads therefore to a preventive effort x which is a function of both the premium and the level of self coverage, or x = x· (Tr,q). As a result, the insurance policy parameters affect the probability of the insured falling ill.

Finally, risk neutrality implies that rewards are valued at their objective measurement. Since for a risk averse decision maker the desire for more rewards with smaller probabilities will decrease (due to the increased risk associated to it), we note that this corresponds to a negative second derivative of the utility function (or to an assumption of concavity) and vice versa for a risk loving decision maker as shown in the table below. To characterize quantitatively a risk attitude, two approaches are basically used: o Risk aversion directly relates to the risk premium, Le.
