探讨了3类关于保费计算原理的相关问题。首先,结合贝叶斯方法和损失原理定义了贝叶斯保费;然后,研究了2类保费计算原理的稳健性质问题:带任意污染系数的非贝叶斯保费的稳健性质和基于ε-污染方法讨论的贝叶斯保费关于先验分布的稳健性质;最后,运用Esscher保费原理分析了当污染在某个分布类变化时保费对污染的响应以及保费的值域。

Three tightly related problems regarding the premium calculation principles are considered. Firstly, Bayesian premiums are defined by using of Bayesian approaches associated with loss principles. Then,two prob-lems regarding the robustness of premium calculation principles are investigated. One is the robustness of non-Bayesian premiums with respect to arbitrary contaminations. The other one is the robustness of Bayesian premiums with respect to the prior distributions by means of theε-contamination arguments. Finally,the reaction of a premi-um with respect to the contaminations and the range of premium using the Esscher principle when the contamina-tion distribution varies in a distribution class are discussed.
