本文研究了两个保险公司的非零和投资再保险博弈。每个保险人的盈余过程是由一个布朗运动漂移。这两家保险公司都可以购买比例再保险,并投资于无风险资产和风险资产。风险资产的价格过程服从常数方差弹性(CEV)模型,并考虑了风险资产的价格过程与索赔过程之间的相关性。每个保险公司的目标是最大化他的终端财富相对于他的竞争对手的预期指数效用。应用随机控制理论,建立了相应的Hamilton-Jacobi-Bellman(HJB)方程,并在指数效用函数下得到了两个保险公司的最优投资再保险策略。此外,我们考虑了保险公司的最优投资再保险策略没有竞争。最后,数值分析了模型参数对最优策略的影响。
In this paper, we study a non-zero-sum investment and reinsurance game for two insurers. Each insurer's surplus process is described by a Brownian motion with drift. Both insurers are allowed to purchase proportional reinsurance and invest in a risk-free asset and a risky asset. The price process of the risky asset follows the constant elasticity of variance (CEV) model, and the correlation between the risky asset's price process and the claim process is considered. Each insurer aims to maximize the expected exponential utility of his terminal wealth relative to that of his competitor. By applying stochastic control theory, we establish the corresponding Hamilton-Jacobi-Bellman (HJB) equation and derive optimal investment-reinsurance strategies for two insurers under exponential utility function. Furthermore, we consider the insurer's optimal investment-reinsurance strategies without competition. Finally, numerical analyses are provided to analyze the effects of model parameters on the optimal strategies.
