We consider partial and complete information models to investigate how partial information has a unique quality over complete information for insurers. We find that optimal reinsurance and investment strategies for the partially informed insurer depend on prior beliefs, whereas those for the completely informed insurer do not. In addition, information quality can affect insurer behaviour, mainly through the relative difference between risk-adjusted market premium and risk-adjusted insurance premium projected on the financial markets. Numerical results indicate that partial information increases the conservativeness of insurer strategies.

最优再保险与投资组合选择：部分信息模型与完全信息模型的比较

我们考虑部分和完全信息模型来研究部分信息如何比完整信息具有独特的质量。我们发现部分知情保险公司的最佳再保险和投资策略取决于先验信念，而完全知情保险公司的最佳再保险和投资策略则不然。此外，信息质量会影响保险人的行为，主要是通过风险调整后市场保费与金融市场上预测的风险调整后保险费之间的相对差异。数值结果表明，部分信息增加了保险公司策略的保守性。
