保险中动态多产品风险分类的预测索赔分数

Predictive Claim Scores for Dynamic Multi-Product Risk Classification in Insurance

Robert Matthijs Verschuren

摘要:

采用广义线性模型(GLM)进行保险定价已经成为非寿险业的标准做法。然而,这些GLM传统上只适用于保单持有人的先验特征,而现在我们越来越多地拥有可用的个人客户的后验信息,有时甚至跨越多个产品类别。因此,在本文中,我们考虑一个动态的索赔分数,以捕捉这一后验信息在几个产品线。更具体地说,我们扩展了Boucher和Inoussa(2014)以及Boucher和Pigeon(2018)的Bonus-Malus面板模型,以包括其他产品类别的索赔分数,并考虑这些分数的非线性效应。由此产生的多产品框架的荷兰财产和意外伤害保险组合的应用程序表明,个人客户的索赔经验可以对风险分类有重大影响,它可以是非常有利可图的帐户。

英文摘要:

It has become standard practice in the non-life insurance industry to employ Generalized Linear Models (GLMs) for insurance pricing. However, these GLMs traditionally work only with a priori characteristics of policyholders, while nowadays we increasingly have a posteriori information of individual customers available, sometimes even across multiple product categories. In this paper, we therefore consider a dynamic claim score to capture this a posteriori information over several product lines. More specifically, we extend the Bonus-Malus-panel model of Boucher and Inoussa (2014) and Boucher and Pigeon (2018) to include claim scores from other product categories and to allow for non-linear effects of these scores. The application of the resulting multi-product framework to a Dutch property and casualty insurance portfolio shows that the claims experience of individual customers can have a significant impact on the risk classification and that it can be very profitable to account for it.
