Public Choice Theory
Public choice theory involves the use of modern economic tools to study problems that are traditionally in the province of political science. (A more general term is "political economy", an earlier name for "economics" that evokes its practical and theoretical origins but should not be mistaken for the Marxian use of the same term.)
In particular, it studies the behavior of voters, politicians, and government officials as (mostly) self-interested agents and their interactions in the social system either as such or under alternative constitutional rules. These can be represented a number of ways, including standard constrained utility maximization, game theory, or decision theory. Public choice analysis has roots in positive analysis ("what is") but is often used for normative purposes ("what ought to be"), to identify a problem or suggest how a system could be improved by changes in constitutional rules. A key formulation of public choice theory is in terms of rational choice, the agent-based proportioning of scarce means to given ends. An overlapping formulation with a different focus is positive political theory. Another related field is social choice theory.
There are also Austrian variants of public choice theory (suggested by Mises, Hayek, Kirzner, Lopez, and Boettke) in which it is assumed that bureaucrats and politicians are benevolent but have access to limited information.

Famous quotes containing the words public, choice and/or theory:
“It is doubtless wise, when a reform is introduced, to try to persuade the British public that it is not a reform at all; but appearances must be kept up to some extent at least.”
—George Bernard Shaw (1856–1950)
“European society has always been divided into classes in a way that American society never has been. A European writer considers himself to be part of an old and honorable tradition—of intellectual activity, of letters—and his choice of a vocation does not cause him any uneasy wonder as to whether or not it will cost him all his friends. But this tradition does not exist in America.”
—James Baldwin (1924–1987)
“Every theory is a self-fulfilling prophecy that orders experience into the framework it provides.”
—Ruth Hubbard (b. 1924)
