Abstract | This paper studies the optimal reinsurance and investment problem for an insurer in a Markovian regime-switching economy with delayed system, in which the market modes are divided into a finite number of regimes, and all the key parameters change according to the value of different market modes. It is assumed that the insurance risk process of the insurer is modulated by a compound Poisson process while the price process of the risky asset is governed by a jump-diffusion model, and that the two jump processes are correlated through a common shock. Under the criterion of maximizing the expected mean-variance utility of terminal wealth, explicit expressions for the optimal strategies and value function are obtained within a game theoretic framework by using the technique of stochastic control theory and the corresponding extended Hamilton-Jacobi-Bellman equation. The existence and uniqueness of the solutions are also verified. Finally, numerical examples are presented to show the impact of some parameters on the optimal results. |
