Fear of ruin and longevity enhancing investment

Rectangularization of the survival probability seems to be an ongoing process. It results from a higher concentration of the ages at death; but it can be reversed by a continuous increase in the limit of life time. In this paper, we assume that these two factors are endogenous and we show that risk averse decision makers exhibit a bias towards rectangularization. More specifically, the importance of the bias depends upon the intensity of the "fear of ruin" which is another measure of the degree of absolute risk aversion.
