The Calculus Of Consent

A scientific study of the political and economic factors influencing democratic decision making

In 1962, economists James M. Buchanan and Gordon Tullock published The Calculus of Consent, in which they developed the principles of public choice theory. In the fifty years since its publication, the book has defined the field and set the standard for research and analysis. To celebrate a half-century of scholarship in public choice, Dwight Lee has assembled distinguished academics from around the world to reflect on the influence of this monumental publication, and, more broadly, the legacy of its legendary authors. Their essays cover a broad spectrum of topics and approaches, from the impact of public choice theory on foreign policy analysis to personal remembrances of learning from and collaborating with Buchanan and Tullock. The result is a unique collection of insights that celebrate public choice and its visionary proponents, while considering its future directions. ​

Buchanan and Tullock’s seminal work, The Calculus of Consent, linked economic methodology to substantive questions in political science. Among the major contributions of their book is a connection between constitutional decision making and contractarianism, a philosophical tradition that proponents believe can give institutions legitimacy. In other words, a major contribution of their book is a clear connection between empirical decision making and normative principles. The current book formalizes and extends their foundational ideas as it attempts to show how economic and philosophical arguments about the "best" voting rules can be used to improve constitutional design. It informs debates about constitutional political economy in comparative politics, democratic theory, and public choice. Political scientists often ask questions about what causes a nation to seek a new constitution, how constitutions are made, and what factors allow for corrupt decision making. The Calculus of Consent and Constitutional Design bridges the gap between normative questions about which institutions are most efficient and fair and empirical questions about how constitutions are formed. This provides a benchmark to help create better constitutions and informs empirical research about what institutions are most likely to succeed. The book begins by showing how contractarian ideals can be used to justify choices about decision-making. It then carefully defines several concepts employed by Buchanan and Tullock and shows why the relationships between these concepts may not be as closely linked as Buchanan and Tullock first thought. This provides a backdrop for analyzing the three phases of constitutional decision-making: 1) the constitutional phase, where rules for constitutional decision making must be justified; 2) the legislative phase, where the optimal k-majority rule is analyzed; and 3) the electoral phase, where the optimal voting rule for large electorates and open alternatives are determined. These phases differ by context and sources of legitimacy. Computational models and analytic techniques are introduced in each of these chapters. Finally, the book concludes with statements about the significance of the research for the creation of constitutions more broadly.

During the past half-century Gordon Tullock continually advanced the frontiers of political economy, most particularly with respect to the workings of representative democracies and of autocracies. This ten-volume series, edited and arranged thematically, brings together Tullock's most significant contributions to economics, political science, public choice, sociology, law and economics, and bioeconomics. Scholars will undoubtedly find the extensive breadth and depth of Tullock's writings enriching. The general reader, as well as the student of politics, and all who love economic liberty, will find Tullock's prose lucid, readable, and sprinkled with wit. His forensic argument is penetrating, compelling, and clear, and his brilliant mind is surprisingly accessible to us all. The Selected Works of Gordon Tullock provides an entr e to the mind of a legend in the field of political economics. Professor Rowley gives a deliberately sparse contextual introduction to each volume, opting to allow the very able and eloquent Tullock to speak for himself. Gordon Tullock (1922-2014) was Professor Emeritus of Law at George Mason University, where he was Distinguished Research Fellow in the Center for Study of Public Choice and University Professor of Law and Economics. He also taught at the University of South Carolina, the University of Virginia, Rice University, Virginia Polytechnic Institute and State University, and the University of Arizona. In 1966 he founded the journal that became Public Choice and remained its editor until 1990. Charles K. Rowley (1939-2013) was Duncan Black Professor of Economics, a Senior Fellow of the James M. Buchanan Center for Political Economy at George Mason University, and the General Director of the Locke Institute.

"The Limits of Liberty is concerned mainly with two topics. One is an attempt to construct a new contractarian theory of the state, and the other deals with its legitimate limits. The latter is a matter of great practical importance and is of no small significance from the standpoint of political philosophy."—Scott Gordon, Journal of Political Economy James Buchanan offers a strikingly innovative approach to a pervasive problem of social philosophy. The problem is one of the classic paradoxes concerning man's freedom in society: in order to protect individual freedom, the state must restrict each person's right to act. Employing the techniques of modern economic analysis, Professor Buchanan reveals the conceptual basis of an individual's social rights by examining the evolution and development of these rights out of presocial conditions.
