报告摘要：This paper extends the classic dividend-reinsurance optimization to the case when insurance company has two lines of business with common shock dependence. Suppose that the insurance company can purchase proportional reinsurance to reduce business risk and pay dividend to keep competitive. The goal is to find out the optimal strategies for maximizing the expected cumulative discounted dividends before bankruptcy. By using the stochastic control techniques, we solve the problems in both cases of positively correlated and negatively correlated models, respectively. The closed-form solutions of the optimal strategies and associated value functions are presented（Joint work with Bo Yang and Ruili Song）.
