在本文中,我们考虑保险公司和再保险公司的最优投资问题。保险公司的财富过程由跳跃扩散风险模型描述,保险公司可以向再保险公司购买比例再保险。保险公司和再保险公司都可以投资于无风险资产和风险资产,其价格过程遵循恒定方差弹性(CEV)模型。此外,还考虑了风险模型与风险资产价格之间的相关性。目标是最大化保险公司和再保险公司最终财富的预期效用。应用随机控制理论,我们建立了相应的 Hamilton-Jacobi-Bellman (HJB) 方程,并推导出指数效用函数的最优投资-再保险策略。最后,提供数值例子来分析参数对最优策略的影响。
In this paper, we consider the optimal investment problem for both an insurer and a reinsurer. The insurer’s wealth process is described by a jump diffusion risk model and the insurer can purchase proportional reinsurance from the reinsurer. Both the insurer and the reinsurer are allowed to invest in a risk-free asset and a risky asset whose price process follows the constant elasticity of variance (CEV) model. Moreover, the correlation between risk model and the risky asset’s price is considered. The objective is maximizing the expected utility of the insurer’s and the reinsurer’s terminal wealth. Applying stochastic control theory, we establish the corresponding Hamilton–Jacobi–Bellman (HJB) equations and derive optimal investment–reinsurance strategies for exponential utility function. Finally, numerical examples are provided to analyze the effects of parameters on the optimal strategies.
