Abstract
In this paper we present final results of a research on the riskiness of a life policies portfolio with “dread disease” (briefly: DD) coverage in additional or early form, referring to the insurer’s point of view. By means of first and second moments of the random present value of gain on a single policy, portfolio ruin probability’s estimates are derived under either Cebicev-Cantelli’s inequality or normal distribution hypothesis, in presence of a low positive correlation among risks and also introducing optimal strategies referred to a surplus reinsurance treaty to face the correlation’s effects. By means of numerical applications based on insurance company’s experiences we show the riskiness and the ruin probability considerably increase when a binary correlation exists and we demonstrate the inefficiency of the EEC minimum solvency margin rule, even in presence of optimal reinsurance strategies.File | Dimensione | Formato | |
