Actuarial models in demography

Abstract

During the last decades, a significant increase in life expectancy has been observed in most countries around the world. This change is mainly due to the improvement of living conditions and the development of medical science. Consequently, a serious demographic problem arises from the increasing number of elderly, combined with low fertility rates. Population ageing creates an additional cost for life insurers and annuity providers. In this spirit, the development of efficient methods to model and forecast the mortality rates of a population is a key challenge for actuaries and demographers. This thesis exploits actuarial credibility techniques to propose novel mortality modelling methods, aiming to contribute in more accurate demographic projections. Before introducing these methods, we firstly examine and review the existing modelling techniques. Greek population data are incorporated into the most used stochastic mortality models under a common age-period-cohort framework. The fitt ...
