Annuities are financial products that guarantee the holder a
fixed return so long as the holder remains alive, thereby providing
insurance against lifetime uncertainty. The terms of these
contracts depend on the information available to insurance firms.
Unlike age and gender, information about individual survival
probabilities cannot be readily ascertained. This asymmetric
information causes market inefficiencies, such as adverse
selection.
Groundbreaking in its scope, "The Economic Theory of Annuities"
offers readers a theoretical analysis of the functioning of private
annuity markets. Starting with a general analysis of survival
functions, stochastic dominance, and characterization of changes in
longevity, Eytan Sheshinski derives the demand for annuities using
a model of individuals who jointly choose their lifetime
consumption and retirement age.
The relation between life insurance and annuities that have a
bequest option is examined and "annuity options" are proposed as a
response to the lack of secondary markets. This book also
investigates the macroeconomic policy implications of annuities and
changes in longevity on aggregate savings. Sheshinski utilizes
statistical population theory to shed light on the debate of
whether the surge in savings and growth in Asia and other countries
can be attributed to higher longevity of the population and whether
this surge is durable.
This book shows how understanding annuities becomes essential
as governments that grapple with insolvency of public social
security systems place greater emphasis on individual savings
accounts.
