THE BEQUEST MOTIVE AND SINGLE PEOPLE’S DEMAND FOR LIFE ANNUITIES

Abstract

The main objective of this paper is to go deeper into the “annuity puzzle” by introducing the altruistic and strategic bequest motive and determining whether this really is a relevant factor affecting the theoretical decision to purchase life annuities. With this end in view we develop an optimization model based on that first put forward by Lejárraga et al. [2002], then add to it elements from other models such as Friedman and Warshawsky’s [1990] and Jousten’s [1998 & 2001] which include the bequest motive. We also analyse welfare by calculating the equivalent wealth in different contexts: the possibility of having access to an actuarially fair life annuity or programmed withdrawal market, the incorporation of so-called market imperfections, and the inclusion of the hypothesis that the individuals already have part of their wealth in pre-existing life annuities.Capitalization, Pension Funds, Phased Withdrawal, Retirement, Utility.
