讲座简介：

In this talk, the design of an optimal insurance policy is discussed from the perspective of a risk-averse insured who would like to maximize the expected utility of his/her final wealth. We assume that the admissible insurance contract satisfies the principle of indemnity and that the upper limits on the first two moments of coverage are imposed by an insurer to restrict its risk exposure and completely determine the quantity of the insurance premium. We derive the optimal insurance policy explicitly, and find that it heavily depends upon the values of the upper limits and the insured’s initial wealth. If the insurance contract is further subject to the condition that the marginal indemnity above a deductible minimum is decreasing in the loss and has a value greater than zero and less than one, we show that for a risk-averse and prudent insured such a contract is suboptimal to a change-loss insurance policy or a dual change-loss insurance policy, depending upon the coefficient of variation of the ceded loss. Especially for variance related premium principles, the change-loss insurance is shown to be optimal.
