Collective Decisions and Voting: The Potential for Public Choice

Nicolaus Tideman

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.

Recenzii

'For people who do not have much background in public choice, this will be an excellent introduction. People who already are familiar with public choice will nevertheless find much in this book which is new to them. It is thus useful both for beginners and for serious students.' Gordon Tullock, George Mason University, USA '...well set out and easily readable...this is a very worthwhile book containing a wealth of useful information.' Voting Matters 'Explores the definition, methods, advantages and disadvantages of collective decisions and applies these considerations to voting theory.' Journal of Economic Literature 'As one would expect from a scholar who has spent more than three decades working in the field, Tideman's knowledge is encyclopedic and his treatment is at all times lucid. If a colleague or graduate student wanted an accessible, comprehensive and reliable guide to the linked disciplines of social choice and public choice, this book would serve that purpose eminently.'

Descriere

Voting is often the most public and visible example of mass collective decision-making. But how do we define a collective decision? And how do we classify and evaluate the modes by which collective decisions are made? This book examines these crucial questions, to discover the true nature of voting as a means of making collective decisions and public choices.
