Book Description
The author examines the interplay between evolutionary game theory and the equilibrium selection problem in noncooperative games. Evolutionary game theory is one of the most active and rapidly growing areas of research in economics. Unlike traditional game theory models, which assume that all players are fully rational and have complete knowledge of details of the game, evolutionary models assume that people choose their strategies through a trial-and-error learning process in which they gradually discover that some strategies work better than others. In games that are repeated many times, low-payoff strategies tend to be weeded out, and an equilibrium may emerge. Larry Samuelson has been one of the main contributors to the evolutionary game theory literature. In Evolutionary Games and Equilibrium Selection, he examines the interplay between evolutionary game theory and the equilibrium selection problem in noncooperative games. After providing an overview of the basic issues of game theory and a presentation of the basic models, the book addresses evolutionary stability, the dynamics of sample paths, the ultimatum game, drift, noise, backward and forward induction, and strict Nash equilibria.

Book Description
This work uses various model frameworks to study the evolution of equilibria in an open loop evolving economy in which the model characteristics evolve without any directional restrictions except for continuity. Applying mathematical methods, it is shown that equilibria can always be adapted in a piecewise gradual, non bang-bang way.

Book Description
This work, based upon the two Manchester Special Lectures given by the author in 1989-90, and focusing on the central economic issues of co-ordination and change, treats these as problems of equilibrium in the case of co-ordination and as problems of evolution in the case of change.

Book Description
This book contains the most sustained and serious attack on mainstream, neoclassical economics in more than forty years. Nelson and Winter focus their critique on the basic question of how firms and industries change overtime. They marshal significant objections to the fundamental neoclassical assumptions of profit maximization and market equilibrium, which they find ineffective in the analysis of technological innovation and the dynamics of competition among firms. To replace these assumptions, they borrow from biology the concept of natural selection to construct a precise and detailed evolutionary theory of business behavior. They grant that films are motivated by profit and engage in search for ways of improving profits, but they do not consider them to be profit maximizing. Likewise, they emphasize the tendency for the more profitable firms to drive the less profitable ones out of business, but they do not focus their analysis on hypothetical states of industry equilibrium. The results of their new paradigm and analytical framework are impressive. Not only have they been able to develop more coherent and powerful models of competitive firm dynamics under conditions of growth and technological change, but their approach is compatible with findings in psychology and other social sciences. Finally, their work has important implications for welfare economics and for government policy toward industry.

Book Description
'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.

Book Description
Economic theory of the last fifty years has been dominated by the paradigm of General Equilibrium Theory, based on the scientific work of Walras-Pareto-Cassel-Wald-Hicks-Arrow-De breu-McKenzie. Some of its grounding assumptions are: all prices are fully flexible; an auctioneer appropriately manipulates all prices according to the law of supply and demand; every con sumer has only one budget constraint; all agents are perfectly informed; no actions are taken by agents before a vector of prices has been found such that all markets clear. Indeed, when all markets clear every agent can implement her/his chosen (opti mal) action and nobody is urged to change his/her decisions. Under these assumptions it is generally said that in a (one pe riod, competitive) general equilibrium model there is no place for money. The present monograph takes general equilibrium as the ba sis on which to build the model presented. But its first aim is to completely dispense with the Walrasian auctioneer by giving firms the task of choosing their output price~ period after period.

Book Description
A new model of economic life that looks at it in terms of ecological interaction and mutation is presented in Evolutionary Economics. It looks at commodities, for example, as if they were a species in the social ecosystem. Boulding describes his new model with clarity and wit, showing its roots in classical economics and exploring the prospects of an evolutionary approach for bettering human conditions.

Book Description
A new view of the economy as an evolving, complex system has been pioneered at the Santa Fe Institute over the last ten years, This volume is a collection of articles that shape and define this view?a view of the economy as emerging from the interactions of individual agents whose behavior constantly evolves, whose strategies and actions are always adapting.The traditional framework in economics portrays activity within an equilibrium steady state. The interacting agents in the economy are typically homogenous, solve well-defined problems using perfect rationality, and act within given legal and social structures. The complexity approach, by contrast, sees economic activity as continually changing?continually in process. The interacting agents are typically heterogeneous, they must cognitively interpret the problems they face, and together they create the structures?markets, legal and social institutions, price patters, expectations?to which they individually react. Such structures may never settle down. Agents may forever adapt and explore and evolve their behaviors within structures that continually emerge and change and disappear?structures these behaviors co-create. This complexity approach does not replace the equilibrium one?it complements it.The papers here collected originated at a recent conference at the Santa Fe Institute, which was called to follow up the well-known 1987 SFI conference organized by Philip Anderson, Kenneth Arrow, and David Pines. They survey the new study of complexity and the economy. They apply this approach to real economic problems and they show the extent to which the initial vision of the 1987 conference has come to fruition.
