The Calculus of Consent, the second volume of Liberty Fund's The Selected Works of Gordon Tullock, is a reprint edition of the ground-breaking economic classic written by two of the world's preeminent economists--Gordon Tullock and Nobel Laureate James M. Buchanan. This book is a unique blend of economics and political science that helped create significant new subfields in each discipline respectively, namely, the public choice school and constitutional political economy. Charles K. Rowley, Duncan Black Professor of Economics at George Mason University, points out in his introduction, "The Calculus of Consent is, by a wide margin, the most widely cited publication of each coauthor and, by general agreement, their most important scientific contribution."
