The Equilibrium Economics Of Leon Walras

The existing literature on Walras has focused on his Elements of Pure Economics to an extent which has unbalanced our view of his work. Jan van Daal and Albert Jolink pay very careful attention to Walras' general equilibrium models, tracing their development through the five editions of his Elements. But they also place his equilibrium exercises in a broader context, arguing that these models should be considered as an instrument in Walras' design for optimal economic order.

Does Walras's theory go beyond perfect competition? Most of the literature on Walras focuses on the Elements of Pure Economics. While this abundance of attention is partly due to the value the economist himself attached to this study, it has created an unbalanced view of his work. In The Equilibrium Economics of Leon Walras, Jan van Daal and Albert Jolink trace the development of Walras's consecutive models of general equilibrium through the five editions of his Elements. The authors also remedy the narrow interpretations of Walras's work by placing his equilibrium theories in a much broader context and argue that these models should be considered as an instrument in Walras's design for optimal economic order. The book falls into three distinct sections. Part I deals with some aspects of Walras's theory - the use of mathematics in economics, the notion of free competition, the notion of utility, and price formation in competitive markets. In Part II these aspects are synthesized in the equilibrium models. Part III outlines Walras's views on what he called the 'social question' and how it led him to formulate regulations with respect to monopoly and the production of public goods, and his ideas on state ownership of the land. The authors argue that all these elements can be brought together in a 'general general equilibrium model' that displays all the features of the models of Part II. Additional material on the life of Leon Walras, technical aspects of his theories and solutions to his equilibrium models and tatonnement can be found in the five appendices. The Equilibrium Economics of Leon Walras thus provides an invaluable introduction to the work of the great French economist.

In order to understand the various strands of general equilibrium theory, why it has taken the forms that it has since the time of Léon Walras, and to appreciate fully a view of the state of general equilibrium theorising, it is essential to understand Walras's work and examine its influence. The first section of this book accordingly examines the foundations of Walras's work. These include his philosophical and methodological approach to economic modelling, his views on human nature, and the basic components of his general equilibrium models. The second section examines how the influence of his ideas has been manifested in the theorising of his successors, surveying the models of theorists such as H. L. Moore, Vilfredo Pareto, Knut Wicksell, Gustav Cassel, Abraham Wald, John von Neumann, J. R. Hicks, Kenneth Arrow, and Gerard Debreu. The treatment also examines models of many types in which Walras's influence is explicitly acknowledged.

General Equilibrium Theory studies the properties and operation of free market economies. The field is a response to a series of questions originally outlined by Leon Walras about the operation of markets and posed by Frank Hahn in the following way: OCyDoes the pursuit of private interest, through a system of interconnected deregulated markets, lead not to chaos but to coherence OCo and if so, how is that achieved?OCO This is always an apt question, but particularly so given the OCyGlobal Financial CrisisOCO that emerged from the operation of market economies in the Americas and Europe in mid to late 2008. The answer that General Equilibrium Theory provides to the Walras-Hahn question is that, under certain conditions coherence is possible, while under certain other conditions chaos, in various forms, is likely to prevail. The conditionality of either outcome is not always well understood OCo neither by proponents of, or antagonists to, the OCyfree market positionOCO. Consequently, this book attempts to show something of what General Equilibrium Theory has to say about the wisdom or otherwise of always relying on OCymarket forcesOCO to manage complex socio-economic systems.

2010 marks the hundredth anniversary of the death of Léon Walras, the brilliant originator and first formaliser of general equilibrium theory – one of the pillars of modern economic theory. In advancing much derided practical solutions Walras also displayed more concern for the problems of living in a second best world than is common in modern pure theories of the invisible hand, efficient market hypothesis, DSGE macroeconomics or the thinking of some contemporary free market admirers all based on general equilibrium theory. This book brings contributions from the likes of Kenneth Arrow, Alan Kirman, Richard Posner, Amartya Sen and Robert Solow to share their thoughts and reflections on the theoretical heritage of Léon Walras. Some authors reminisce on the part they played in the development of modern general economics theory; others reflect on the crucial part played by general equilibrium in the development of macroeconomics, microeconomics, growth theory, welfare economics and the theory of justice; others still complain about the wrong path economic theory took under the influence of post 1945 developments in general equilibrium theory.

This is an English translation of the third edition (1896) of León Walras' Elements of Theoretical Economics. The translators of the work undertook this project for three reasons. First, this edition is Walras's best theoretical work. Second, the two subsequent editions contain new elements that spoil his previous work; furthermore, important parts of the third edition do not appear in the subsequent editions. Third, William Jaffé's translation (1954) of the last edition is now outdated in the light of recent research on Walras's ideas; furthermore, Jaffé's terminology in the parts shared by the third and subsequent editions is not always accurate.

First Published in 2004. Studies in Applied Economics is an English translation of Études d’économie politique appliquée (1898) by Léon Walras (1834–1910). Until now, Éléments d’économie politique pure (1874) was the only book by Walras available in English (Elements of Pure Economics, 1954). It contains the theory of general economic equilibrium under free competition, with the concept of utility maximization as its core. Walras’s conclusion was that where free competition is possible, it should be the rule. So, in the present book, he advocates protective regulation, within which economic agents may compete freely. For water, gas or railway transport, for instance, where free competition is impossible, rules are formulated to maintain its advantages. Issues such as money, capital, credit, banking and the stock markets are also dealt with. The book’s final chapter recapitulates the themes of Walras’s three main works: Éléments, Études d’économie sociale and this volume, Études d’économie politique appliquée. Walras’s aim was to provide an economic blueprint for a social ideal where poverty and similar evils could be banished.

This book sheds new light on the general equilibrium theory of Léon Walras (1834–1910) from a historical perspective. Walras's construction of general equilibrium theory marked the dawn of modern economics, and the theory was greatly developed in the 20th century. However, Walras's own intentions and ideas behind the theory are still not fully understood. This book aims to clarify the intellectual background of Walras’s economics by delving into his original writings, which have not received much attention until now. Part 1 of the book reconsiders the relationship between Walras and his predecessors, Adam Smith (1723–1790), Jean-Baptiste Say (1767–1832), and Achylle Nicolas Isnard (1749–1803), who are believed to have had a decisive influence on Walras's general equilibrium theory. In Part 2, the book explores Walras's views on the labor market, entrepreneurship, and non-selfish human nature, including concepts like sympathy, which have been overlooked in his general equilibrium theory and subsequently misunderstood to this day. Walras’s economic thought is one of the foundational sources of modern economics. An accurate and in-depth understanding of it will provide a new perspective on the problems faced by modern economics and open future possibilities for economics as a social science. This book offers new insights not only to researchers and students of the history of economics but also to all those interested in the origins of modern economics.
