J. M. Buchanan's contractarian constitutionalism: political economy for democratic society.

The purpose of this paper is to support three claims. Firstly, that it is Buchanan's uncompromising commitment to a methodological and a normative individualism to which his lifework owes its coherence and internal consistency. Secondly, that a principal motivating force behind his life-long research efforts has been the aim of inquiring into how the citizen-members of a democratic polity may govern themselves in mutually beneficial ways. And, thirdly, that his contractarian constitutionalism provides a paradigmatic alternative to received outlooks of liberalism, welfare economics, and democratic theory. [ABSTRACT FROM AUTHOR]
