报告摘要:In this work, we investigate the optimal per-claim reinsurance problem to minimize the insurer's ruin probability. Inspired by the exponential upper bound of ruin probability in Cramér-Lundberg model, we take Lundberg exponent maximization as the value function. In the first part, we consider the optimal reinsurance problem under the combined upper moment premium principle. In the second part, we consider the optimal reinsurance problem for an insurer who has different belief about claims with the reinsurer based on the perspective of risk control. With the technique of piecewise modification, we extend the method adopted in Tan et al. [European J. Oper. Res., 282(2020), pp. 345-362] and Meng et al. [SIAM J. Financial Math., 13(2022), pp. 903-943]. This approach proposed here has good applicability for modifying reinsurance candidate to satisfy the incentive compatibility condition based on other value functions, such as the utility maximization problem. As examples, we also present the explicit reinsurance structures under a few representative belief heterogeneity environments.
