Parts three and four are devoted to algebraic and combinatorial aspects of social choice theory, including analyses of Arrow's Theorem, consensus functions, and the role of geometry. Part five deals with the application of cooperative game theory to social choice.
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
This book covers the main topics of welfare economics — general equilibrium models of exchange and production, Pareto optimality, un certainty, externalities and public goods — and some of the major topics of social choice theory — compensation criteria, fairness, voting. Arrow's Theorem, and the theory of implementation. The underlying question is this: "Is a particular economic or voting mechanism good or bad for society?" Welfare economics is mainly about whether the market mechanism is good or bad; social choice is largely about whether voting mechanisms, or other more abstract mechanisms, can improve upon the results of the market. This second edition updates the material of the first, written by Allan Feldman. It incorporates new sections to existing first-edition chapters, and it includes several new ones. Chapters 4, 6, 11, 15 and 16 are new, added in this edition. The first edition of the book grew out of an undergraduate welfare economics course at Brown University. The book is intended for the undergraduate student who has some prior familiarity with microeconomics. However, the book is also useful for graduate students and professionals, economists and non-economists, who want an overview of welfare and social choice results unburdened by detail and mathematical complexity. Welfare economics and social choice both probably suffer from ex cessively technical treatments in professional journals and monographs.
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.
"Choice, Welfare and Measurement contains many of Amartya Sen's most important contributions to economic analysis and methods, including papers on individual and social choice, preference and rationality, and aggregation and economic measurement. A substantial introductory essay interrelates his diverse concerns, and also analyzes discussions generated by the original papers, focusing on the underlying issues."--P. [4] of cover.
Kenneth Arrow's pathbreaking Òimpossibility theoremÓ was a watershed in the history of welfare economics, voting theory, and collective choice, demonstrating that there is no voting rule that satisfies the four desirable axioms of decisiveness, consensus, nondictatorship, and independence. In this book, Amartya Sen and Eric Maskin explore the implications of ArrowÕs theorem. Sen considers its ongoing utility, exploring the theoremÕs value and limitations in relation to recent research on social reasoning, while Maskin discusses how to design a voting rule that gets us closer to the idealÑgiven that achieving the ideal is impossible. The volume also contains a contextual introduction by social choice scholar Prasanta K. Pattanaik and commentaries from Joseph E. Stiglitz and Kenneth Arrow himself, as well as essays by Sen and Maskin outlining the mathematical proof and framework behind their assertions.
First published in 1986, this volume of essays offers an examination of the philosophical foundations of social choice theory, in its context as the outgrowth of welfare economics. The essays advance both criticisms and suggestions for alternative approaches.
This book inquires into the Capability Approach, a value theory of freedom, which crystalizes the interests of Marx, Welfare Economics, Social Choice, and Ethics. The capability approach has attracted many people as a promising interdisciplinary approach to human well-being and social worlds, finely overarching ethical and economic concerns. It has well challenged essential characteristics of welfare economics, which focuses on the criterion of efficiency with the concept of utility, by explicitly incorporating normative criteria such as agency, well-being and real freedom into positive analysis. However, it has a bit operational and methodological difficulties such that how to estimate an individual capability set which includes potential multi-dimensional functioning vectors. This book reminds the reader of what traditional economics has left behind, by examining historical backgrounds, scrutinizing philosophical foundations and providing an operational formulation of the capability approach: indispensable for understanding what the capability approach is about and what it can achieve.
