This book offers a comprehensive overview and critique of the most important political and philosophical interpretations of the basic results of social choice, assessing their plausibility and seeking to identify the links between the theory of social choice and the more traditional issues of political theory and philosophy. In this regard, the author eschews a strong methodological commitment or technical formalism; the approach is instead based on the presentation of political facts and illustrated via numerous real-life examples. This allows the reader to get acquainted with the philosophical and political dispute surrounding voting and collective decision-making and its links to social choice theory.

The mathematical theory of voting has intellectual roots extending back two centuries to the writings of Borda and Condorcet. Yet it has only been in the last forty years that general theorems have begun to emerge. With the publication of this volume, Norman Schofield brings the results together in a ,common framework. SOCIAL CHOICE AND DEMOCRACY, however, is not merely a synthetic exercise, for Schofield's own work over the last decade has constituted a major initiative in deepening and' broadening our general understanding of voting arrangements. At last the results of his research, bits and pieces of which have been reported in a number of journals of international standing and in various collections, are coherently and systematically presented as an entirety. For students of democracy -- chiefly philosophers and political scientists, but increasingly economists as well -- the insights of this volume are profound. From it I infer the following.

This book presents the most complete set of analytical, normative, and historical discussions of majority decision making to date. One chapter critically addresses the social-choice approach to majority decisions, whereas another presents an alternative to that approach. Extensive case studies discuss majority voting in the choice of religion in early modern Switzerland, majority voting in nested assemblies such as the French Estates-General and the Federal Convention, majority voting in federally organized countries, qualified majority voting in the European Union Council of Ministers, and majority voting on juries. Other chapters address the relation between majority decisions and cognitive diversity, the causal origin of majority decisions, and the pathologies of majority decision making. Two chapters, finally, discuss the counter-majoritarian role of courts that exercise judicial review. The editorial Introduction surveys conceptual, causal, and normative issues that arise in the theory and practice of majority decisions.

Originally published in 1951, "Social Choice and Individual Values" introduced "Arrow's Impossibility Theorem" and founded the field of social choice theory in economics and political science. This new edition, including a new foreword by Nobel laureate Eric Maskin, reintroduces Arrow's seminal book to a new generation of students and researchers."Far beyond a classic, this small book unleashed the ongoing explosion of interest in social choice and voting theory. A half-century later, the book remains full of profound insight: its central message, 'Arrow's Theorem, ' has changed the way we think."--Donald G. Saari, author of "Decisions and Elections: Explaining the Unexpected "

Originally published in 1970, this classic study has been recognized for its groundbreaking role in integrating economics and ethics, and for its influence in opening up new areas of research in social choice, including aggregative assessment. It has also had a large influence on international organizations, including the United Nations, notably in its work on human development. The book showed that the “impossibility theorems” in social choice theory—led by the pioneering work of Kenneth Arrow—do not negate the possibility of reasoned and democratic social choice. Sen’s ideas about social choice, welfare economics, inequality, poverty, and human rights have continued to evolve since the book’s first appearance. This expanded edition preserves the text of the original while presenting eleven new chapters of fresh arguments and results. “Expanding on the early work of Condorcet, Pareto, Arrow, and others, Sen provides rigorous mathematical argumentation on the merits of voting mechanisms...For those with graduate training, it will serve as a frequently consulted reference and a necessity on one’s book shelf.” —J. F. O’Connell, Choice

Using the economic approach of "social choice theory", this unique book examines difficulties found in democratic processes involved in the creation and implementation of planning policies. Special attention is given to communicative planning and the logical reasons why all the desirable properties of dialogue cannot be simultaneously attained.

This book offers a comprehensive and sustained critique of theories of deliberative democracy.

Governing requires choices, and hence trade-offs between conflicting goals or criteria. This book asserts that legitimate governance requires explanations for such trade-offs and then demonstrates that such explanations can always be found, though not for every possible choice. In so doing, John W. Patty and Elizabeth Maggie Penn use the tools of social choice theory to provide a new and discriminating theory of legitimacy. In contrast with both earlier critics and defenders of social choice theory, Patty and Penn argue that the classic impossibility theorems of Arrow, Gibbard, and Satterthwaite are inescapably relevant to, and indeed justify, democratic institutions. Specifically, these institutions exist to do more than simply make policy - through their procedures and proceedings, these institutions make sense of the trade-offs required when controversial policy decisions must be made.

Offering a fascinating biography of a foundational theory, Amadae reveals not only how the ideological battles of the Cold War shaped ideas but also how those ideas may today be undermining the very notion of individual liberty they were created to defend.

This is a book about liberal democratic values and their implications for the design of political institutions. Its distinctive feature is the use of some simple mathematical techniques (known as social choice theory) to clarify and defend a rather complex utilitarian conception of the liberal democratic 'way of life' based on John Stuart Mill's work. More specifically, the text focuses on three well-known 'social choice paradoxes' which are commonly held to destroy any possibility of an ideal harmony among liberal democratic values; and draws upon suggestions implicit in Mill's writings to develop an ethically appealing liberal democratic social choice framework in which the aforementioned paradoxes no longer cause concern. The revised framework is a rather complex version of utilitarianism and should be of special interest to welfare economists, social choice theorists, democratic political theorists and philosophers concerned with utilitarian ethics.
