保持复合混合更新过程结构的渐进等效概率测度的特征

A characterization of progressively equivalent probability measures preserving the structure of a compound mixed renewal process

Spyridon M. Tzaninis, Nikolaos D. Macheras

摘要:

推广了Delbaen和Haezendonck [5]以及[18]和[16]的工作,对于给定的复合混合更新过程S在概率测度P下,我们刻画了P上所有的概率测度Q,使得Q和P是渐进等价的,并且S在Q下仍是复合混合更新过程,并具有改进的性质.证明了任何复合混合更新过程都可以通过测度变换转化为复合混合泊松过程。在[26]和[27]中分别讨论了与破产问题和保险市场中没有套利机会的保费计算原理的计算相关的应用。

英文摘要:

Generalizing earlier works of Delbaen & Haezendonck [5] as well as of [18] and [16] for given compound mixed renewal process S under a probability measure P, we characterize all those probability measures Q on the domain of P such that Q and P are progressively equivalent and S remains a compound mixed renewal process under Q with improved properties. As a consequence, we prove that any compound mixed renewal process can be converted into a compound mixed Poisson process through a change of measures. Applications related to the ruin problem and to the computation of premium calculation principles in an insurance market without arbitrage opportunities are discussed in [26] and [27], respectively.
