This is a new edition - with a substantial new introduction - of a book which has had a significant impact on economics, philosophy and political science. Robert Sugden shows how conventions of property, mutual aid, and voluntary supply of public goods can evolve spontaneously out of the interactions of self-interested individuals, and can become moral norms. Sugden was among the first social scientists to use evolutionary game theory. His approach remains distinctive in emphasizing psychological and cultural notions of salience.

A groundbreaking intellectual biography of one of the twentieth century's most influential economists The First Serious Optimist is an intellectual biography of the British economist A. C. Pigou (1877–1959), a founder of welfare economics and one of the twentieth century's most important and original thinkers. Though long overshadowed by his intellectual rival John Maynard Keynes, Pigou was instrumental in focusing economics on the public welfare. And his reputation is experiencing a renaissance today, in part because his idea of "externalities" or spillover costs is the basis of carbon taxes. Drawing from a wealth of archival sources, Ian Kumekawa tells how Pigou reshaped the way the public thinks about the economic role of government and the way economists think about the public good. Setting Pigou's ideas in their personal, political, social, and ethical context, the book follows him as he evolved from a liberal Edwardian bon vivant to a reserved but reform-minded economics professor. With World War I, Pigou entered government service, but soon became disenchanted with the state he encountered. As his ideas were challenged in the interwar period, he found himself increasingly alienated from his profession. But with the rise of the Labour Party following World War II, the elderly Pigou re-embraced a mind-set that inspired a colleague to describe him as "the first serious optimist." The story not just of Pigou but also of twentieth-century economics, The First Serious Optimist explores the biographical and historical origins of some of the most important economic ideas of the past hundred years. It is a timely reminder of the ethical roots of economics and the discipline's long history as an active intermediary between the state and the market.

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.
