What do Self-Reports of Wellbeing Say about Life-Cycle Theory and Policy? Angus Deaton. NBER Working Paper No. 24369. http://www.nber.org/papers/w24369

Abstract: I respond to Atkinson's plea to revive welfare economics, and to considering alternative ethical frameworks when making policy recommendations. I examine a measure of self-reported evaluative wellbeing, the Cantril Ladder, and use data from Gallup to examine wellbeing over the life-cycle. I assess the validity of the measure, and show that it is hard to reconcile with familiar theories of intertemporal choice. I find a worldwide optimism about the future; in spite of repeated evidence to the contrary, people consistently but irrationally predict they will be better off five years from now. The gap between future and current wellbeing diminishes with age, and in rich countries, is negative among the elderly. I also use the measure to think about income transfers by age and sex. Policies that give priority those with low incomes favor the young and the old, while utilitarian policies favor the middle aged, and men over women.
