The Economic Theory of Annuities

Eytan Sheshinski has written the definitive book on the economics of annuities. In light of the demographic transitions in many countries and the changing nature of social insurance, this work will be extremely important in the years ahead. -- Jerry R. Green, Harvard University This book develops the economic theory of private annuity markets and fills an important gap in previous research. Its systematic and insightful analysis provides a foundation on which future students of insurance markets, and policy analysts concerned with these markets, are sure to build. -- James Poterba, Massachusetts Institute of Technology With exceptional clarity, Sheshinski presents the analysis of savings and annuitization, incorporating new results and raising interesting research questions. -- Peter Diamond, Massachusetts Institute of Technology This work is a very complete study of a surprisingly neglected field. The technical and conceptual problems raised by uncertainty as to the individual's lifetime, central to this study, are handled with great skill and is well written. -- Kenneth J. Arrow, Nobel Prize-winning economist

Annuities are financial products that guarantee the holder a fixed return so long as the holder remains alive, thereby providing insurance against lifetime uncertainty. This book offers readers a theoretical analysis of the functioning of private annuity markets.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.
