International Adverse Selection in Life Insurance and Annuities

Abstract

Insurance specialists recognize that well-functioning insurance markets – in the form of both life insurance products and annuities – are necessary to ensure effective funded retirement systems and efficient national saving. This is because annuities play an essential role in converting asset accumulations into a regular flow of retirement income guaranteed for life, and classical life insurance protects individuals and their dependants from the risk of early death. But as actuaries know, it takes a great deal of statistical information on mortality patterns by age and sex to develop the necessary survival forecasts needed for valuing annuity and insurance products. And in practice many countries lack a vital statistics collection mechanism, especially for insured lives and annuitants, causing analysts there to rely on mortality data from other countries in order to value insurance products of all types. This paper uses data from three relatively well-developed insurance markets to analyze the differences between the mortality of individuals who have purchased non-annuity insurance products and the general population in these countries. Comparison with previous results permits a comprehensive picture of the effects of adverse selection on mortality and hence on valuation of insurance products in these three markets.
