When one thinks about how collective decisions are made, voting is the method that comes naturally to mind. But other methods such as random process and consensus are also used. This book explores just what a collective decision is, classifies the methods of making collective decisions, and identifies the advantages and disadvantages of each method. Classification is the prelude to evaluation. What are the characteristics of a method of making collective decisions, the book asks, that permit us to describe a collective decision as good? The second part of the book is detailed exploration of voting: the dimensions in which voting situations differ, the origins and logic of majority rule, the frequency of cycles in voting, the Arrow and Gibbard-Satterthwaite theorems, criteria for ways of cutting through cycles and the application of these criteria to a variety of rules, voting over continuums, proportional representation, and voting rules that take account of intensities of preferences. Relatively unknown methods of voting give voting a much greater potential than is generally recognized. Collective Decisions and Voting is essential reading for everyone with an interest in voting theory and in how public choices might be made.

Every day thousands of decisions are made by all kinds of committees, parliaments, councils and boards by a 'yes-no' voting process. Sometimes a committee can only accept or reject the proposals submitted to it for a decision. On other occasions, committee members have the possibility of modifying the proposal and bargaining an agreement prior to the vote. In either case, what rule should be used if each member acts on behalf of a different-sized group? It seems intuitively clear that if the groups are of different sizes then a symmetric rule (e.g. the simple majority or unanimity) is not suitable. The question then arises of what voting rule should be used. Voting and Collective Decision-Making addresses this and other issues through a study of the theory of bargaining and voting power, showing how it applies to real decision-making contexts.

This textbook provides a survey of the literature of social choice. It integrates the ethical aspects of the subject, (discussing potentially desirable conditions for social judgements) with positive aspects of decision mechanisms that centre on the revelation of true preferences. The literature on the subject presently consists of a great many papers. This book draws them together in common notation and points out interpretations which are often missing in specialist papers. Applications in economics, electoral politics, and ethics are discussed. The book will be used by senior undergraduate and graduate students of economics, political science and philosophy as a text book in the subject.

In the last decade the techniques of social choice theory, game theory and positive political theory have been combined in interesting ways so as to pro vide a common framework for analyzing the behavior of a developed political economy. Social choice theory itself grew out of the innovative attempts by Ken neth Arrow (1951) and Duncan Black (1948, 1958) to extend the range of economic theory in order to deal with collective decision-making over public goods. Later work, by William Baumol (1952), and James Buchanan and Gordon Tullock (1962), focussed on providing an "economic" interpretation of democratic institutions. In the same period Anthony Downs (1957) sought to model representative democracy and elections while William Riker (1962) made use of work in cooperative game theory (by John von Neumann and Oscar Morgenstern, 1944) to study coalition behavior. In my view, these "rational choice" analyses of collective decision-making have their antecedents in the arguments of Adam Smith (1759, 1776), James Madison (1787) and the Marquis de Condorcet (1785) about the "design" of political institutions. In the introductory chapter to this volume I briefly describe how some of the current normative and positive aspects of social choice date back to these earlier writers.

Individual decision making can often be wrong due to misinformation, impulses, or biases. Collective decision making, on the other hand, can be surprisingly accurate. In Democratic Reason, Hélène Landemore demonstrates that the very factors behind the superiority of collective decision making add up to a strong case for democracy. She shows that the processes and procedures of democratic decision making form a cognitive system that ensures that decisions taken by the many are more likely to be right than decisions taken by the few. Democracy as a form of government is therefore valuable not only because it is legitimate and just, but also because it is smart. Landemore considers how the argument plays out with respect to two main mechanisms of democratic politics: inclusive deliberation and majority rule. In deliberative settings, the truth-tracking properties of deliberation are enhanced more by inclusiveness than by individual competence. Landemore explores this idea in the contexts of representative democracy and the selection of representatives. She also discusses several models for the "wisdom of crowds" channeled by majority rule, examining the trade-offs between inclusiveness and individual competence in voting. When inclusive deliberation and majority rule are combined, they beat less inclusive methods, in which one person or a small group decide. Democratic Reason thus establishes the superiority of democracy as a way of making decisions for the common good.

Any normative theory of democracy involves notions of equity, which are supposed to guide collective decisions. On the other hand, a descriptive theory of any decision-making body must take into account the distribution of power in that body. The development of collective decision theory along two different paths reflects these two foci of interest in the theory of democracy. One direction can be subsumed under the theory of social choice, the other under the theory of games. In the theory of social choice, the participants are characterized only by their preferences among a set of alternatives (candidates, courses of action, etc. ). They do not choose among these alternatives. They only submit their preferences to some central authority ("the Society"), which then chooses among the alternatives in accordance with some fixed rule of aggregating the preferences. On the other hand, the point of departure in the theory of games is a set of actors, each of whom can choose between alternative courses of action (strategies). The totality of choices results in an outcome, which gener ally has different utilities for the different actors. In this book, both approaches are presented in selected papers, from which the reader can get an excellent overview of the state of the art. Both branches of formal decision theory, the theory of social choice and the theory of games, were developed in mathematical language, but very little technical mathematical knowledge is required to follow the arguments.

"The significance of this account should be clear. If, as economists frequently assert, proper diagnosis of the disease is a crucial prerequisite to treatment, then the design of appropriate democratic institutions depends critically on a coherent analysis of the way the electoral process works and the perversities to which it is prone. The claim is that the interest-based account incorrectly diagnoses the disease. Accordingly, this book ends with an account of the institutional protections that go with expressive voting."--BOOK JACKET.
