This book was released on 2013-04-17 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Voting paradoxes are unpleasant surprises encountered in voting. Typically they suggest that something is wrong with the way in dividual opinions are being expressed or processed in voting. The outcomes are bizarre, unfair or otherwise implausible, given the expressed opinions of voters. Voting paradoxes have an important role in the history of social choice theory. The founding fathers of the theory, Marquis de Condorcet and Jean-Charles de Borda, were keenly aware of some of them. Indeed, much of the work of these and other forerunners of the modern social choice theory dealt with ways of avoiding paradoxes related to voting. One of the early paradoxes, viz. that bearing the name of Condorcet, has subsequently gained such a prominent place in the literature that it is sometimes called the paradox of voting. One of the aims of the present work is to show that Condorcet's is but one of many paradoxes of voting. Some of these are pretty closely interrelated making it meaningful to classify them. This is the second main aim of this book. The third objective is to suggest ways of dealing with paradoxes. Since voting is and has always been an essential instrument of democratic rule, it is of some in terest to find out how voting paradoxes are being dealt with by past and present methods of voting. Of even greater interest is to find ways of minimizing the probability of occurrence of various paradoxes. By their very nature some paradoxes are unavoidable.

This book was released on 2010-11-11 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: The likelihood of observing Condorcet's Paradox is known to be very low for elections with a small number of candidates if voters’ preferences on candidates reflect any significant degree of a number of different measures of mutual coherence. This reinforces the intuitive notion that strange election outcomes should become less likely as voters’ preferences become more mutually coherent. Similar analysis is used here to indicate that this notion is valid for most, but not all, other voting paradoxes. This study also focuses on the Condorcet Criterion, which states that the pairwise majority rule winner should be chosen as the election winner, if one exists. Representations for the Condorcet Efficiency of the most common voting rules are obtained here as a function of various measures of the degree of mutual coherence of voters’ preferences. An analysis of the Condorcet Efficiency representations that are obtained yields strong support for using Borda Rule.
Download or read book Chaotic Elections written by Donald Saari and published by American Mathematical Soc.. This book was released on 2001-04-03 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: What does the 2000 U.S. presidential election have in common with selecting a textbook for a calculus course in your department? Was Ralph Nader's influence on the election of George W. Bush greater than the now-famous chads? In Chaotic Elections!, Don Saari analyzes these questions, placing them in the larger context of voting systems in general. His analysis shows that the fundamental problems with the 2000 presidential election are not with the courts, recounts, or defective ballots, but are caused by the very way Americans vote for president. This expository book shows how mathematics can help to identify and characterize a disturbingly large number of paradoxical situations that result from the choice of a voting procedure. Moreover, rather than being able to dismiss them as anomalies, the likelihood of a dubious election result is surprisingly large. These consequences indicate that election outcomes--whether for president, the site of the next Olympics, the chair of a university department, or a prize winner--can differ from what the voters really wanted. They show that by using an inadequate voting procedure, we can, inadvertently, choose badly. To add to the difficulties, it turns out that the mathematical structures of voting admit several strategic opportunities, which are described. Finally, mathematics also helps identify positive results: By using mathematical symmetries, we can identify what the phrase ``what the voters really want'' might mean and obtain a unique voting method that satisfies these conditions. Saari's book should be required reading for anyone who wants to understand not only what happened in the presidential election of 2000, but also how we can avoid similar problems from appearing anytime any group is making a choice using a voting procedure. Reading this book requires little more than high school mathematics and an interest in how the apparently simple situation of voting can lead to surprising paradoxes.
Download or read book Mathematics to the Rescue of Democracy written by Paolo Serafini and published by Springer Nature. This book was released on 2020-03-02 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explains, in a straightforward way, the foundations upon which electoral techniques are based in order to shed new light on what we actually do when we vote. The intention is to highlight the fact that no matter how an electoral system has been designed, and regardless of the intentions of those who devised the system, there will be goals that are impossible to achieve but also opportunities for improving the situation in an informed way. While detailed descriptions of electoral systems are not provided, many references are made to current or past situations, both as examples and to underline particular problems and shortcomings. In addition, a new voting method that avoids the many paradoxes of voting theory is described in detail. While some knowledge of mathematics is required in order to gain the most from the book, every effort has been made to ensure that the subject matter is easily accessible for non-mathematicians, too. In short, this is a book for anyone who wants to understand the meaning of voting.

Download or read book Decisions and Elections written by Donald Saari and published by Cambridge University Press. This book was released on 2001-10-22 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is not uncommon to be frustrated by the outcome of an election or a decision in voting, law, economics, engineering, and other fields. Does this 'bad' result reflect poor data or poorly informed voters? Or does the disturbing conclusion reflect the choice of the decision/election procedure? Nobel Laureate Kenneth Arrow's famed theorem has been interpreted to mean 'no decision procedure is without flaws'. Similarly, Nobel Laureate Amartya Sen dashes hope for individual liberties by showing their incompatibility with societal needs. This highly accessible book offers a new, different interpretation and resolution of Arrow's and Sen's theorems. Using simple mathematics, it shows that these negative conclusions arise because, in each case, some of their assumptions negate other crucial assumptions. Once this is understood, not only do the conclusions become expected, but a wide class of other phenomena can also be anticipated.

Download or read book Gaming the Vote written by William Poundstone and published by Macmillan. This book was released on 2009-02-17 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: At least five U.S. presidential elections have been won by the second most popular candidate, because of "spoilers"--Minor candidates who take enough votes away from the most popular candidate to tip the election. The spoiler effect is a consequence of the "impossibility theorem," discovered by Nobel laureate economist Kenneth Arrow, which asserts that voting is fundamentally unfair--and political strategists are exploiting the mathematical faults of the simple majority vote. This book presents a solution to the spoiler problem: a system called range voting, already widely used on the Internet, which is the fairest voting method of all, according to computer studies. Range voting remains controversial, however, and author Poundstone assesses the obstacles confronting any attempt to change the American electoral system.--From publisher description.
Download or read book Numbers Rule written by George Szpiro and published by Princeton University Press. This book was released on 2020-11-03 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author takes the general reader on a tour of the mathematical puzzles and paradoxes inherent in voting systems, such as the Alabama Paradox, in which an increase in the number of seats in the Congress could actually lead to a reduced number of representatives for a state, and the Condorcet Paradox, which demonstrates that the winner of elections featuring more than two candidates does not necessarily reflect majority preferences. Szpiro takes a roughly chronological approach to the topic, traveling from ancient Greece to the present and, in addition to offering explanations of the various mathematical conundrums of elections and voting, also offers biographical details on the mathematicians and other thinkers who thought about them, including Plato, Pliny the Younger, Pierre Simon Laplace, Thomas Jefferson, John von Neumann, and Kenneth Arrow.

Available in PDF, EPUB and Kindle. Book excerpt: Capturing Campaign Effects is the definitive study to date of the influence of campaigns on political culture. Comprising a broad exploration of campaign factors (debates, news coverage, advertising, and polls) and their effects (priming, learning, and persuasion), as well as an impressive survey of techniques for the collection and analysis of campaign data, Capturing Campaign Effects examines different kinds of campaigns in the U.S. and abroad and presents strong evidence for significant campaign effects. "Capturing Campaign Effects is an accessible and penetrating account of modern scholarship on electoral politics. It draws critical insights from a range of innovative analyses." --Arthur Lupia, University of Michigan "What a wonderful way to usher in the new era of election studies! This book spotlights fascinating paradoxes in the literature of voting behavior, highlights many promising approaches to resolving those paradoxes, and shows how these strategies can yield important findings with terrific payoffs for our understanding of contemporary democracy. Fasten your seatbelts, folks: scholarship on elections is about to speed up thanks to this collection of great essays." --Jon Krosnick, Stanford University "The past decade has seen a renewed interest in understanding campaign effects. How and when do voters learn? Does the election campaign even matter at all? Capturing Campaign Effects draws on leading political scientists to address these matters. The result is a collection that will become the major reference for the study of campaigns. The lesson that emerges is that campaigns do affect voter decision making, usually for the better." --Robert S. Erikson, Columbia University Henry E. Brady is Class of 1941 Monroe Deutsch Professor of Political Science and Public Policy, and Director of the Survey Research Center at the University of California, Berkeley.

Download or read book The Paradox of Mass Politics written by W. Russell Neuman and published by Harvard University Press. This book was released on 1986 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: A central current in the history of democratic politics is the tensions between the political culture of an informed citizenry and the potentially antidemocratic impulses of the larger mass of individuals who are only marginally involved in the political world. Given the public's low level of political interest and knowledge, it is paradoxical that the democratic system works at all. In The Paradox of Mass Politics W. Russell Neuman analyzes the major election surveys in the United States for the period 1948-1980 and develops for each a central index of political sophistication based on measures of political interest, knowledge, and style of political conceptualization. Taking a fresh look at the dramatic findings of public apathy and ignorance, he probes the process by which citizens acquire political knowledge and the impact of their knowledge on voting behavior. The book challenges the commonly held view that politically oriented college-educated individuals have a sophisticated grasp of the fundamental political issues of the day and do not rely heavily on vague political symbolism and party identification in their electoral calculus. In their expression of political opinions and in the stability and coherence of those opinions over time, the more knowledgeable half of the population, Neuman concludes, is almost indistinguishable from the other half. This is, in effect, a second paradox closely related to the first. In an attempt to resolve a major and persisting paradox of political theory, Neuman develops a model of three publics, which more accurately portrays the distribution of political knowledge and behavior in the mass population. He identifies a stratum of apoliticals, a large middle mass, and a politically sophisticated elite. The elite is so small (less than 5 percent) that the beliefs and behavior of its member are lost in the large random samples of national election surveys, but so active and articulate that its views are often equated with public opinion at large by the powers in Washington. The key to the paradox of mass politics is the activity of this tiny stratum of persons who follow political issues with care and expertise. This book is essential reading for concerned students of American politics, sociology, public opinion, and mass communication.

Download or read book Democracies Divided written by Thomas Carothers and published by Brookings Institution Press. This book was released on 2019-09-24 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: “A must-read for anyone concerned about the fate of contemporary democracies.”—Steven Levitsky, co-author of How Democracies Die 2020 CHOICE Outstanding Academic Title Why divisions have deepened and what can be done to heal them As one part of the global democratic recession, severe political polarization is increasingly afflicting old and new democracies alike, producing the erosion of democratic norms and rising societal anger. This volume is the first book-length comparative analysis of this troubling global phenomenon, offering in-depth case studies of countries as wide-ranging and important as Brazil, India, Kenya, Poland, Turkey, and the United States. The case study authors are a diverse group of country and regional experts, each with deep local knowledge and experience. Democracies Divided identifies and examines the fissures that are dividing societies and the factors bringing polarization to a boil. In nearly every case under study, political entrepreneurs have exploited and exacerbated long-simmering divisions for their own purposes—in the process undermining the prospects for democratic consensus and productive governance. But this book is not simply a diagnosis of what has gone wrong. Each case study discusses actions that concerned citizens and organizations are taking to counter polarizing forces, whether through reforms to political parties, institutions, or the media. The book’s editors distill from the case studies a range of possible ways for restoring consensus and defeating polarization in the world’s democracies. Timely, rigorous, and accessible, this book is of compelling interest to civic activists, political actors, scholars, and ordinary citizens in societies beset by increasingly rancorous partisanship.
Download or read book Multicriteria and Multiagent Decision Making with Applications to Economics and Social Sciences written by Aldo G. S. Ventre and published by Springer. This book was released on 2013-12-06 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides a comprehensive and timely report on the topic of decision making and decision analysis in economics and the social sciences. The various contributions included in the book, selected using a peer review process, present important studies and research conducted in various countries around the globe. The majority of these studies are concerned with the analysis, modeling and formalization of the behavior of groups or committees that are in charge of making decisions of social and economic importance. Decisions in these contexts have to meet precise coherence standards and achieve a significant degree of sharing, consensus and acceptance, even in uncertain and fuzzy environments. This necessitates the confluence of several research fields, such as foundations of social choice and decision making, mathematics, complexity, psychology, sociology and economics. A large spectrum of problems that may be encountered during decision making and decision analysis in the areas of economics and the social sciences, together with a broad range of tools and techniques that may be used to solve those problems, are presented in detail in this book, making it an ideal reference work for all those interested in analyzing and implementing mathematical tools for application to relevant issues involving the economy and society.
