In the second half of the 20th century, the Virginia school of political economy has emerged as an important research program that explores the boundary between law, economics and politics. Although that research program is now carried out by many prominent economists and political scientists around the world, the work and personality of James Buchanan has always played an important role in its development, and in its appeal. http://rdc1.net/forthcoming/jmbvap.pdf
"Buchanan's book, The Calculus of Consent (1962), co-authored with Gordon Tullock, is considered one of the classic works that founded the discipline of public choice, a melding of economics and political science. In particular (1962, p. v), the book is about the political organization of a free society. But its method, conceptual apparatus, and analytics "are derived, essentially, from the discipline that has as its subject the economic organization of such a society."
The Calculus of Consent argues that government decisions are part of the economy, not exogenous factors. Therefore, methods of collective decisions must be studied as part of the study of the public sector. Calculus further describes the constitution as the line that is drawn between private and collective action. Public choice is then divided between pre- and post-constitutional phases.
Buchanan has also written extensively on the theory of the fiscal constitution. His work The Power to Tax: Analytical Foundations of a Fiscal Constitution (with Geoffrey Brennan) was ground breaking on how fiscal decisions are made. Buchanan's writings have also challenged traditional assumptions about the role of self interest in political decision making.
Public Choice theory has evolved into two branches — a normative branch which attempts to derive principles of an appropriately organized set of public decisions, and a positivist branch which attempts to develop predictive theories of behavior.
