The Calculus Of Consent And Constitutional Design

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.

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. ​

This book is written for anyone, anywhere sitting down to write a constitution. The book is designed to be educative for even those not engaged directly in constitutional design but who would like to come to a better understanding of the nature and problems of constitutionalism and its fundamental building blocks - especially popular sovereignty and the separation of powers. Rather than a 'how-to-do-it' book that explains what to do in the sense of where one should end up, it instead explains where to begin - how to go about thinking about constitutions and constitutional design before sitting down to write anything. Still, it is possible, using the detailed indexes found in the book, to determine the level of popular sovereignty one has designed into a proposed constitution and how to balance it with an approximate, appropriate level of separation of powers to enhance long-term stability.

Societies function on the basis of rules. These rules, rather like the rules of the road, coordinate the activities of individuals who have a variety of goals and purposes. Whether the rules work well or ill, and how they can be made to work better, is a matter of major concern. Appropriately interpreted, the working of social rules is also the central subject matter of modern political economy. This book is about rules - what they are, how they work, and how they can be properly analysed. The authors' objective is to understand the workings of alternative political institutions so that choices among such institutions (rules) can be more fully informed. Thus, broadly defined, the methodology of constitutional political economy is the subject matter of The Reason of Rules. The authors have examined how rules for political order work, how such rules might be chosen, and how normative criteria for such choices might be established.
