讲座摘要:In this talk, we investigate optimal investment and proportional reinsurance policies for an insurer who subject to random time solvency regulation. The goal of the insurer is to maximize the probability of reaching a bequest goal before the random regulation time arrives. We assume that the insurer's surplus and the financial market are both modulated by external macro environment, which is specified by an external Markov chain. By solving an auxiliary control problem, together with the fixed point method, we prove the regularity of the value function. Explicit optimal polices are obtained when the premium is calculated by expectation principle. For more general cases, the Markov chain approximation algorithm is used here to show some key parameters, such as the intensity of regulation and macroeconomic conditions, on the optimal policies through numerical examples.
