Competition and efficiency is at the core of economic theory. This volume collects papers of leading scholars, which extend the conventional general equilibrium model in important ways: Efficiency and price regulation are studied when markets are incomplete and existence of equilibria in such settings is proven under very general preference assumptions. The model is extended to include geographical location choice, a commodity space incorporating manufacturing imprecision and preferences for club-membership, schools and firms. Inefficiencies arising from household externalities or group membership are evaluated. Core equivalence is shown for bargaining economies. The theory of risk aversion is extended and the relation between risk taking and wealth is experimentally investigated. Other topics include determinacy in OLG with cash-in-advance constraints, income distribution and democracy in OLG, learning in OLG and in games, optimal pricing of derivative securities, the impact of heterogeneity at the individual level for aggregate consumption, and adaptive contracting in view of uncertainty.

Macroeconomics is evolving in an almost dialectic fashion. The latest evolution is the development of a new synthesis that combines insights of new classical, new Keynesian and real business cycle traditions into a dynamic, stochastic general equilibrium (DSGE) model that serves as a foundation for thinking about macro policy. That new synthesis has opened up the door to a new antithesis, which is being driven by advances in computing power and analytic techniques. This new synthesis is coalescing around developments in complexity theory, automated general to specific econometric modeling, agent-based models, and non-linear and statistical dynamical models. This book thus provides the reader with an introduction to what might be called a Post Walrasian research program that is developing as the antithesis of the Walrasian DSGE synthesis.

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 2006 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.

One may have various reasons for compiling a volume of papers devoted to and inspired by Walras and Pareto. Pareto succeeded Walras in 1893 on the chair of Political Economy at the University of Lausanne. The relation between the two was not always without tensions, although Pareto, on the occasion of his 25 years jubilee celebration, at least in part, transferred the honours offered to him to Walras. Indeed, one may say that to a substantial extent important parts of the works of Pareto would not have been possible without the insights of Walras. Both eminent scientists also have in common that the image of their inheritance professed to the common university trained economic scholars ('cutes') is a highly restricted caricature of the fullnes of their essential insights and contributions, and students of sociology or politicology may even finish their academic studies without ever having heard the name of Pareto. What cutes "know" about Walras amounts to the following caricature. Walras developed the general economic equilibrium model, but did not care about uniqueness and stability of an equilibrium. It is a model with exchange and production only and it assumes an auctioneer who announces price vectors to establish the equilibrium. The model presupposes perfect information and is static and certainly not dynamic. Walras had a bias towards free competition and laisser faire and neglected monopoly and taxation. Pareto is known by the cutes as the founding father of welfare economics. At best one is informed the notions of Pareto-optimality conditions and the first and second welfare theorems. But welfare economics is in general disappearing from the university research and teaching programs, replaced as it is by consumer and producer surpluses in the nowadays flourishing partial industrial economics programs. In this thought-provoking collection, ten international scholars offer reflections and new interpretations of Walras’and Pareto’s unique contributions to topics as broad as the over-arching important of the social sciences, the development of modern microeconomics and (in particular) econometrics, political economy and public choice, and political sociology. Their insights will be of particular interest to researchers and scholars of economic history, political sociology, and the social sciences.
