The happiness puzzle: analytical aspects of the Easterlin paradox

We apply an optimizing model with relative comparisons (habit formation) in consumption and labour supply to the economics of happiness, specifically the 'Easterlin paradox'. Studying a generalization of the paradox, which we label the 'happiness puzzle', we analyse ways in which income growth affects happiness. In our model, those factors include agents' risk aversion; whether the economy experiences balanced or unbalanced growth; how non-pecuniary factors affect well-being; and the degree of market imperfections. We also demonstrate that the dynamic specification of habit formation rather than its mere existence matters for whether the happiness puzzle arises on a balanced growth path. Only when habit is modelled in ratio form, does this possibility open up. Our model thus bridges the gap between theory, empirics and social policy. It provides a basis for studying a number of specific policy issues, such as corrective taxes. Copyright 2012 Oxford University Press 2011 All rights reserved, Oxford University Press.
