英文摘要:
We consider the problem of seeking an optimal set of model points associated to a fixed portfolio of life insurance policies. Such an optimal set is characterized by minimizing a certain risk functional, which gauges the average discrepancy with the fixed portfolio in terms of the fluctuation of the interest rate term structure within a given time horizon. We prove a representation theorem which provides two alternative formulations of the risk functional and which may be understood in connection with the standard approaches for the portfolio immunization based on sensitivity analysis. For this purpose, a general framework concerning some techniques of stochastic integration in Banach space and Malliavin calculus is introduced. A numerical example is discussed when considering a portfolio of whole life policies.

中文摘要:
我们考虑的问题是寻找一组与固定寿险保单组合相关的最优模型点。这种最优集的特点是最小化某个风险函数,该函数根据给定时间范围内利率期限结构的波动来衡量与固定投资组合的平均差异。我们证明了一个表示定理,该定理提供了风险函数的两个可选公式,并且可以结合基于敏感性分析的组合免疫的标准方法来理解。为此,介绍了Banach空间和Malliavin演算中一些随机积分技术的一般框架。在考虑终身保单组合时,讨论了一个数值例子。
