Equilibrium and Disequilibrium in Economic Theory


Book Description

This volume is the result of a conference held at the Institute for Advanced Studies, Vienna. There is still a gap reflected both in fundamental meth odological differences and in the style of analysis between the Walrasian (and Edgeworthian) tradition of general equilibrium theory and the theo retical and policy problems raised in the framework of Keynesian and post-Keynesian macroeconomics. The conference succeeded in bringing together economic theorists working in fields ranging from abstract prob lems of mathematical equilibrium analysis to applied macroeconomic theory, and it is hoped that the present volume will contribute to bridging the above-mentioned hiatus. As organizer of the meeting and editor of its proceedings I want to thank the Institute for Advanced Studies for providing facilities and funds. I am also sincerely grateful to all my colleagues from the Institute for their generous help, in particular to Mrs Monika Herkner without whose assistance and organizational talent the conference would certainly not have been the success it in fact - in the opinion of all participants - turned out to have been. Furthermore, I wish to express my gratitude towards all participants in the meeting and contributors to the volume whose patient support of the whole enterprise proved indispensable. To Mrs Elfriede Auracher I am deeply indebted for her skillful and effective general management of the editorial work and her invaluable assistance in compiling the indexes.




Disequilibrium Foundations of Equilibrium Economics


Book Description

The most common mode of analysis in economic theory is to assume equilibrium. Yet, without a proper theory of how economies behave in disequilibrium, there is no foundation for such a practice. The necessary step in proposing a foundation is the formulation of a theory of stability, and in this 1984 book, Professor Fisher is primarily concerned with this subject, although disequilibrium behavior itself is analyzed. The author first undertakes a review of the existing literature on the stability of general equilibrium. He then proposes a more satisfactory general model in which agents realize their state of disequilibrium and act on arbitrage opportunities. The interrelated topics of the role of money, the nature of quantity constraints, and the optimal behaviour of arbitraging agents are extensively treated.




The International Monetary System and the Theory of Monetary Systems


Book Description

The international monetary system, and the disparate systems that make it up, are complex and there are many fallacies surrounding the ways in which they work. This book provides a clear and rigorous understanding of these systems and their possible consequences.




Disequilibrium Economics


Book Description

This book discusses mathematical models for various applications in economics, with a focus on non-linear dynamics. Based on the author’s over 50 years of active work in the field, the book has been inspired by models from the period between 1920 and 1950. Following a brief introduction to economics for mathematicians and other modelers, it assembles a repository of useful specific functions for global dynamic modeling. Furthermore, twelve “research stubs” – outlined research agendas that have not yet been fully worked on – are suggested for further study and could even be expanded to entire research projects. The book is a valuable resource, particularly for young scientists who are skilled in mathematical and computational techniques and are looking for applications in economics.




Transforming Modern Macroeconomics


Book Description

Since the 1950s, macroeconomics has been transformed. This book is about one of the most important aspects of that transformation: the attempt, through the end of the twenty-first century and beyond, to construct macroeconomic models rigorously derived from models of individual firms and households.




Economics without Equilibrium


Book Description

This book contains lectures delivered at Yale University in October, 1983, in memory of Arthur M. Okun, showing how Lord Kaldor relates his own views of economic process to those of Okun, particularly the theory of markets set in Okun's magnum opus, Prices and Quantities, posthumously published.




How Markets Work


Book Description

Mainstream neo-classical economics focuses on already attained states of equilibrium. It is silent about the processes of adjustment to equilibrium; Human action consists of 'grappling with an essentially unknown future', not being confronted with clearly specified objectives, known resources and defined courses of action as mainstream theory assumes; Critics of the market economy find ammunition in neo-classical theory: they 'merely need to tick off the respects in which real world capitalism departs from the requirements for perfectly competitive optimality'; The theory of entrepreneurial discovery allows economists to escape from the 'analytical box' in which 'choice' simply consists of computing a solution implicit in given data; An entrepreneurial act of discovery consists in 'realising the existence of market value that has hitherto been overlooked'. Scope for entrepreneurial discovery occurs in a world of disequilibrium -- which is quite different from the equilibrium world of mainstream economics where market outcomes are foreordained; Entrepreneurial discovery explains why one price tends to prevail in a market. Though new causes of price differences continually appear, entrepreneurs exploit the resulting profit opportunities and produce a tendency towards a single price; Only with the introduction of entrepreneurship is it possible to appreciate how markets work. Without entrepreneurship, there would be no market co-ordination; So-called 'imperfections' of competition are often 'crucial elements in the market process of discovery and correction of earlier entrepreneurial errors'; Advertising expenditures, for example, are means of alerting consumers to 'what they do not know that they do not know'. Anti-trust laws may hamper market processes and prevent competitive entry to markets; so. Entrepreneurial profit, far from generating injustice, is a 'created gain'. It is not `sliced from a pre-existing pie ... it is a portion which has been created in the very act of grasping it'.







Strategizing, Disequilibrium, and Profit


Book Description

This book starts from the proposition that frameworks used in business strategy lack realism because they are built on equilibrium-based foundations carried over from the domain of neoclassical economics. Mathews proposes instead a conceptual framework consistent with the turbulence found in real economies, and brings strategizing into conformity with such phenomena as innovation and technological change, network formation, capture of substitution effects in modular systems, and many other interesting features of modern economies that are passed over by mainstream equilibrium-based analysis. This new framework is based on the way firms assemble resources into a distinctive bundle, then build activities out of these resources to generate revenue, and link the resources to the activities through routines created and administered by management.




Current Issues in Microeconomics


Book Description

Part of a series designed to provide undergraduate students with information on developments in economics, this volume contains nine essays which cover subjects of current relevance in microeconomics, such as choice under uncertainty, microeconometrics and game theory.
