Dr Sure Mataramvura, will present the Department of Statistical Science seminar with a talk entitled, "An optimal reinsurance management and dividend payout strategy when the insurer's reserve is an Itô-Lévy process"

We consider the problem of an insurer who decides to allocate a proportion (1 - a(t)) of premiums to a re-insurance company (thereby retaining a proportion a(t) of premiums). The insurer also has to pay dividends c(t) at any time t to shareholders. If the insurer's reserve is x(t) given by the modi ed Cramer- Lundberg model that allows jumps, we solve a dual optimal policy of a dividend payout scheme for shareholders with constant relative risk aversion (CRRA) preferences and retention level of received premiums for the insurance company . We set the problem as a stochastic control problem and solve the resulting HJB equation . We nd that the optimal risk level and dividend payout can never depend on time. Other important results are discussed in detail.
