Abstract

We report the results of experiments on economic decisions with two populations, one of healthy elderly individuals (average age 82) and one of younger students (average age 20). We examine confidence, decisions under uncertainty, differences between willingness to pay and willingness to accept and the theory of mind (strategic thinking). Our findings indicate that the older adults’ decision behavior is similar to that of young adults, contrary to the notion that economic decision making is impaired with age. Choices over lotteries do not reflect the age differences previously reported in the psychology and biology literature. Moreover, some of the demonstrated decision behaviors suggest that the elderly individuals are less biased than the younger individuals.(1)There is a greater prevalence of overconfident behavior in the younger population. (2) Our results show no significant support for a theory of an endowment effect in either population. (3) Both populations perform similarly on the beauty contest task, although there is a modest indication of a higher incidence of confused behavior by the older.
