题 目：Dynamic Bivariate Mortality Modelling

摘 要：
We introduce a new approach to analyze the mortality dependence between two individuals in a couple which is intended to describe in a dynamic framework the joint mortality of married couples. The proposed framework aims to incorporate bivariate status information and capture, by adjusting some parametric form, the desired effect such as the “broken-heart syndrome”. To this end, we use a well-suited multiplicative decomposition, which will serve as a building block for the framework to relate the dependence structure and the marginals, and we make the link with existing practice of affine mortality models. Finally, we propose some illustrative examples and show how the underlying model allows to describe the main stylized facts of bivariate mortality dynamics. This is a joint work with Yahia Salhi and Shihua Wang.
