报告内容：In this talk, we study the economic implications of ambiguous correlation in a non-zero-sum stochastic differential investment and reinsurance game between two insurance companies. Each insurance company's surplus process consists of a proportional reinsurance protection and an investment in risky and risk-free assets. Each insurance company is assumed to maximize his utility of the difference between his terminal surplus and that of his competitor.

The surplus process of each insurance company is modeled by a mixed regime-switching Cram\'{e}r-Lundberg diffusion approximation process, i.e. the coefficients of the diffusion risk processes are modulated by a continuous-time Markov chain and an independent market-index process. Correlation between the two surplus processes, independent of the risky asset process, is allowed. The general framework of Nash equilibrium for the coupled optimization problem is established. The optimal reinsurance/investment, and the resulting value processes of the insurance companies are obtained in closed forms, together with sound economic interpretations, for the case of an exponential utility function.
