Systematic improvements in mortality increases dependence in the survival distributions of insured lives, which is not … portfolios. This paper applies a multivariate gamma distribution to incorporate dependence. Lifetimes are modelled using a … truncated multivariate gamma distribution that induces dependence through a shared gamma distributed component. Model parameter …

Also the dependence between ages is an important component in the modeling of mortality (Barrieu et al., 2011). It is … to be high (as noted in Denton et al., 2005). This suggests that there is value in exploring the dependence structure …
