Abstract: We provide a review of scientific contributions on mortality heterogeneity, focusing in particular on “unobservable” heterogeneity and the related impact on life insurance and life annuity business. We start with an overview of methodological contributions to heterogeneity and frailty modeling, coming from both the demographical and the actuarial context. We then shift to contributions analyzing the impact of frailty, in its various interpretations, on the results (cash flows, profits, etc.) of insurance and annuity portfolios and related risk profiles.
