This volume presents a collection of thirty-four essays and shorter works by James M. Buchanan that represent the brilliance of his founding work on public-choice theory. The work of James M. Buchanan is perhaps most often associated with his helping to found public-choice theory. Buchanan's book-length works such as 'The Calculus of Consent' or 'The Reason of Rules' (Volumes 3 and 10, respectively, in Liberty Fund's 'The Collected Works of James M Buchanan') are best known for their brilliant application of market behavioural models to government. But Buchanan's shorter works represented here all show originality and insight as well as clear articulation of important theoretical principles. What's more, these essays have all had a significant impact on the subsequent literature about public choice. In this volume, the works are broken down into these major categorical groupings: general approach; public choice and its critics; voters; voting models; rent seeking; regulation; public choice and public expenditures. As Robert D Tollison concludes his foreword to this volumes, "Read in conjunction with the other parts of the 'Collected Works', these papers offer the reader a fuller appreciation of the public-choice revolution and its impact and prospects."
