Passions and interests revisited: the psychological foundations of economics and politics

Homo Politicus, Homo Oeconomicus. Can these two abstract human types meaningfully be distinguished? Is there a characteristic set of motivations that drive human beings in so far as they are political actors and a different set that drive their economic lives? What are the psychological foundations of economics and politics? The answers to these questions have significant implications both for the study and the practice of economics and politics. If homo politicus is essentially identical to homo oeconomicus, it is safe to generalize from the study of economic behavior to political phenomena. If not, such a procedure will distort our understanding of politics. Similarly, if we design political institutions and public policies assuming that people will behave as they do when they confront economic choices, we may find our intentions thwarted if we have neglected the distinctive motivations characteristic of political action.
