'Bert Tieben is very well read in the history of economic thought and provides an overview of one of the basic concepts of economics that is unrivalled both in its scope and in its thoughtful and detailed discussion of the various currents and schools. It goes right to the heart of economic theory and asks some pertinent questions about the limits and the future of economic theorizing. That is, I think, what sets it apart from many other studies in the history of economic thought: it is history with an eye to the future, and it does all this without making any demands on the mathematical skills of the reader. This book should therefore appeal to everybody who is interested in the methodology of economics and in exploring the boundaries of economic analysis.' Hans Visser, VU University, Amsterdam, The Netherlands This book deals with one of the most puzzling concepts in economic science, that of economic equilibrium. In modern economics, equilibrium is considered a key assumption, but its role is contested by economists both from within the mainstream and from rival schools of thought. What explains the contradictory assessments of the equilibrium concept in economics? Do economists belonging to different traditions disagree about the definition of equilibrium or do they adopt different rules for assessing scientific status? In this unique and exhaustive study, Bert Tieben answers these questions by investigating the history of equilibrium economics from 1700 to the present day. He concludes that ideology strongly coloured the development of this branch of theory, helping to explain the vehemence of the debates surrounding the concept. He also argues that scientific progress in economics may indeed be fostered by such opposition and contention, and calls for cross fertilization and stronger cooperation between the different schools of thought. This resourceful book will appeal to post graduate students and scholars in the history of economic thought and economic methodology. Both neoclassical and heterodox economists, most notably Austrian, post Keynesian and institutional economists, will also find much to interest them.

This book considers the treatment of equilibrium by several of the most important schools of thought in economics, including: * neoclassical economics, * the neo-Ricardian economics, * Post-Keynesian economics - both those who follow Joan Robinson in denying any interpretative role to equilibrium in economic theorizing and those who use the notion of equilibrium, but re-defined from a Classical or Keynesian perspective.

The economic theory of general equilibrium underpins the most important models used in economic theory in general and in its more specialized areas such as macroeconomics, international trade, environmental economics, growth theory, and developmental economics. In Foundations of the Theory of General Equilibrium, leading academic scholar, Yves Balasko offers a good introduction to the economic theory of general equilibrium and makes use of various mathematical tools as intuitive and easy as possible. The second half of the book addresses properties of the general equilibrium model that are still at the frontier of current research. These properties deal with the characterization of economies with a unique equilibrium and, more generally, with the relationships between the number of equilibria and the fundamentals of an economy.

General Equilibrium Theory, which became the dominating paradigm after the Second World War, is founded on the postulated existence, uniqueness, and stability of equilibrium in economic processes. Since then, the concept has come under sustained attack from all points of the heterodox compass, from Austrian economists to Marxists. Partly in response to these pressures, mainstream economics has changed and moved away from the rigid framework of GET. Nonetheless, economists are continually arguing in terms of equilibrium and the existence of a variety of equilibrium concepts continues to stir controversy. The contributions in this book, which include articles from Tony Lawson, Ivor Grattan-Guinness and Roger Backhouse, highlight current notions of equilibrium in economics and provide a guide to understanding the links between economic theory and economic reality.

One of the core building blocks of traditional economic theory is the concept of equilibrium, a state of the world in which economic forces are balanced and in the absence of external influences the values of economic variables remain static. Many traditional equilibrium models, or equilibria, are established based on the rational behavior of individuals within financial markets, such as traders, market analysts, and investing firms, and their ability to maximize profits, no matter the cost. Yet what happens when these market participants behave in an irrational manner, and how does this impact economic equilibria? Contemporary economists have agreed that a process similar to Darwin’s Theory of Natural Selection takes over, whereby equilibria are shaped not by the behavior of individual participants but by an environment outside its control (i.e., an environment with little concern for maximizing profits). It is an environment in which those “selected” produce positive financial gains, but have no regard for how it was obtained or underlying motivations—and those participants suffering losses disappear altogether. Evolutionary Foundations of Equilibria in Irrational Markets proves traditional economic equilibria continue to occur despite natural selection in irrational markets. It covers a wide sampling of equilibria under various scenarios, and each chapter addresses the results of these models at an aggregate level. The text is supplemented with charts and figures to drive home key findings and proofs, making it of interest to students and researchers in the areas of economics and behavioral finance.

Petri (University of Siena) argues that many of the problems of general equilibrium theory arose with the shift from the traditional long-period method in the study of value and distribution to the very- short-period method characteristic of contemporary theory. He asserts that mathematical economists influenced by Hick's Value and capital inherite

One of the reasons which make the Keynesian controversy still so live, is the missing distinction between aspects concerning methodology and others pertaining to theory. Another cause of the ongoing debate is to be found in unsettled problems concerning methodology, in primis the concept the equilibrium. Nor could the situation have been different, given, on the one hand, Keynes's manifest disaffection with these matters (especially in The General Theory) and, on the other hand, their implications as regards Keynesian economic theory and policy. The aim of this volume ensues from this analysis; accordingly, a wide spectrum of questions of method are considered and different interpretations of Keynes's approach in this field are taken into consideration.

This study of the fundamental theoretical underpinnings of modern economies examines how economists define and categorize the market. It suggests that modeling a social science such as economics on the physical/mathematical sciences has created intractable problems, and that the basic structure of the theory needs rethinking.A meticulously researched work in the field of mathematical economics and pure theory, The Invisible Hand traces the evolution of general economic equilibrium theory in its rich interaction with the physical sciences over a period of more than 150 years. The authors discuss how the "invisible hand" that balances physical processes was inspiration and model for the creation of general economic equilibrium theory.Ingrao and Israel review fundamental concepts of the theory, showing how its early forms, strictly analogous to mechanical equilibrium, arose from the cultural atmosphere generated by Newtonianism and the French Enlightenment. They describe developments and changes in the theory from the work of Leon Walras and Vilfredo Pareto through restructuring by the Vienna group and John Von Neumann and the contributions of the Robbins group at the London School of Economics, to its current formulations in the work of Irving Fisher, Paul Samuelson, Kenneth Arrow, and Gerard Debreu.Concluding chapters survey the results obtained in attempts to deal with questions of the existence of equilibrium, its uniqueness, and the problem of global stability. Ingrao and Israel find that the theory has arrived at a dead end, which raises serious doubts about the internal consistency of the basic model.Bruna Ingrao is Associate Professor of Economics at the University of Sassari and Giorgio Israel is Associate Professor of Mathematics at the University of Rome.

This book brings together the author's pioneering work, written over the last twenty years, on the use of differential methods in general equilibrium theory.

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.
