摘要
假设保险公司在考虑比例再保险下,并将盈余资金在无风险资产和风险型资产中进行配置,考虑了利率的随机性,建立了求解相应的HJB方程,并针对CARA效用函数求解HJB方程,得出最优的再保险比例和在各类资产中的投资比例。
Assume that the insurer allocates its surplus between risk-free asset and risky asset, we consider the proportional reinsurance policy with a stochastic interest rate and establish Hamilton-Jacobi-Bellman (HJB) equation. We solve it with a CARA utility and obtain optimal reinsurance and investment strategies.
