James Duesenberry as a practitioner of behavioral economics

Abstract

In 1949 James Duesenberry published Income, saving and the theory of consumer behavior. His objective was to solve a puzzle presented by the macroeconomic data on consumption. To do so, he created the Relative Income Hypothesis. Duesenberry explicitly challenged the neoclassical assumption of independent consumer preferences and made use of ideas that are now common in behavioral economics: loss aversion, status quo bias, spotlight effects, herd behavior, and interdependent preferences. He also raised policy questions about the effect of redistributive taxes on national saving. To answer the questions he raised, we need empirical research by behavioral economists. Finally, the issue arises as to why the Relative Income Hypothesis has virtually disappeared from economics even though it is superior to the Permanent Income Hypothesis that replaced it.
