Three Kinds of Economists:

A bstract . The diversity of thought among American economistsis investigated using samples of the memberships of the American Economic Association, the Union for Radical Political Economists and the Association for Evolutionary Economics. Discriminant analysis reveals a complex web of theoretical and organizational integration and separatism involving theoretical orientation in economics, emulative economists, scholarly research focus, organizational membership, and political values. The modal radical economist espouses a radical political economic philosophy and pursues Marxist/radical scholarship in an academic setting. The modal neoclassical economist , radical in neither disciplinary nor personal political beliefs, is found, more often than the other types, in nonacademic administrative work. Marxist/radical and institutionalist scholarship are mutually exclusive. Other dimensions of the professional role, as well as a number of social and biographical background characteristics, do not differentiate between types of economists.
