Political economy most commonly refers to interdisciplinary studies drawing upon economics, sociology and political science in explaining how political institutions, the political environment, and the economic system—capitalist, socialist, communist, or mixed—influence each other. The "Journal of Economic Literature" classification codes associate political economy with three sub-areas: (1) the role of government and/or class and power relationships in resource allocation for each type of economic system; (2) international political economy, which studies the economic impacts of international relations; and (3) economic models of political or exploitative class processes. Much of the political economy approach is derived from public choice theory on the one hand and radical political economics on the other hand, both dating from the 1960s.
