![عکس صفحه اول مقاله: Heterogeneity of Australian population mortality and implications for a viable life annuity market Heterogeneity of Australian population mortality and implications for a viable life annuity market](/preview/png/5076918.png)
Heterogeneity in mortality rates is known to exist in populations, undermining the use of age and sex as the only rating factors for life insurance and annuity products. Life insurers offering life annuities assume that annuitant lives will self-select, and price the longevity risk with an annuity mortality table that assumes above-average longevity. This leads to annuities being less attractive to a wide range of individuals, and limits the viability of private annuity markets. This paper quantifies heterogeneity and its financial implications for annuity prices using well-established frailty models and a more recently developed Markov ageing model calibrated to population mortality data. The heterogeneity implied for each model is quantified using Australian population mortality. The models are compared by considering the distribution of heterogeneity by age implied by the models and the implications for life annuity prices.
⺠The paper quantifies heterogeneity and its financial implications for annuity prices. ⺠Frailty models are compared to a recently developed Markov ageing model. ⺠Heterogeneity for each model is quantified using Australian population mortality. ⺠Models are compared using the implied distribution of heterogeneity by age. ⺠Implications of the models for life annuity pricing are quantified.
