Large deviations for a model of excess of loss re-insurance
نویسندگان
چکیده
A risk model of a joint business (insurer/re-insurer) is studied in the Large Deviations (LD) regime. In the model considered, the premium paid by the insurer to the re-insurer changes if the insurer’s capital falls below a certain level P . An optimal premium arrangement for the both business participants is investigated. By a proper choice of parameters involved, it is possible to increase the rate function, i.e. reduce the ruin probability of insurer, in such a way that the expected profit of re-insurer remains controllable, i.e., does not exceed a given percentage of the total loss.
