This is a book on general equilibrium in which firms are allowed to exhibit increasing returns to scale (more precisely, in which the convexity of production sets is not assumed). As such, it provides a full fledged general equilibrium model and analyzes the chief questions concerning existence and optimality. Increasing returns is a topic which many economists find it to be simultaneously very imponant, very difficult and very discouraging. It is very important because it refers to a well established technological phenomenon which is essentially incompatible with the functioning of competitive markets. It is very difficult because the standard concepts and tools for the analysis fail (in particular, the supply mappings are not well defined). It is very discouraging because the available models do not seem to solve the basic questions: Normative models where nonconvex firms follow marginal pricing do not achieve efficient outcomes, and positive models cannot incorporate monopolistic competition as a way of defming the behavior of those firms with increasing returns to scale. I would like to think that this monograph will contribute to show that "the increasing returns question" is neither too difficult nor too discouraging. Concerning the difficulty, it will be shown that the analysis can be carried out with essentially the same tools as those applicable to the standard competitive model. As for the relevance of the results available, let me point out the following.

Policies affecting resource allocation across tradable sectors and those affecting the incentives to produce tradable activities are key determinants of macroeconomic balance and growth. Computable general equilibrium models have made significant contributions to both types of policies. With advancements in computing power and software, these models have become easy to implement and are now widespread. The question then is when and how to formulate them to avoid the ‘black box’ syndrome.This book seeks to address these issues through carefully selected essays that analyse how to model general equilibrium linkages in a single economy, across developing and developed economies, and across both micro and macro policies. Micro policies examined include tariffs quotas and VERs, the choice of taxes to maximize government revenue, migration and remittances, and the political economy of tariff setting. Applications on macro policies cover capital inflows, real exchange rate determination, and the modeling of the effects of adjustment policies on income distribution.The book provides insights on the development of a family of models for diverse policy choices, focusing on the ways to model the following: links between tradable and non-tradable activities, labor markets, and portfolio choices given limited capital mobility. Selected essays are all inspired by specific policy problems, including the adaptation to external shocks (i.e. oil), consequences of capital inflows, determinants of migration and associated remittances, the productivity of foreign aid, and rent-seeking activities under trade regimes with non-price trade restrictions. Examples in this book lay out the theoretical foundations, alongside a variety of applications, to help formulate coherent and transparent models for policy analysis. Archetype economies are extensively used to show how differences in economic structure influence the effects of policies. Graduate students and policy analysts interested in modeling will find this a useful compendium of studies.

The concept of general equilibrium, one of the central components of economic theory, explains the behavior of supply, demand, and prices by showing that supply and demand exist in balance through pricing mechanisms. The mathematical tools and properties for this theory have developed over time to accommodate and incorporate developments in economic theory, from multiple markets and economic agents to theories of production. Yves Balasko offers an extensive, up-to-date look at the standard theory of general equilibrium, to which he has been a major contributor. This book explains how the equilibrium manifold approach can be usefully applied to the general equilibrium model, from basic consumer theory and exchange economies to models with private ownership of production. Balasko examines properties of the standard general equilibrium model that are beyond traditional existence and optimality. He applies the theory of smooth manifolds and mappings to the multiplicity of equilibrium solutions and related discontinuities of market prices. The economic concepts and differential topology methods presented in this book are accessible, clear, and relevant, and no prior knowledge of economic theory is necessary. General Equilibrium Theory of Value offers a comprehensive foundation for the most current models of economic theory and is ideally suited for graduate economics students, advanced undergraduates in mathematics, and researchers in the field.

The aim of this book is to incorporate Marshallian ideas such as external increasing returns and monopolistic competitions into the general equilibrium framework of Walrasian tradition. New chapters and sections have been added to this revised and expanded edition of General Equilibrium Analysis of Production and Increasing Returns (World Scientific, 2009).The new material includes a presentation of equilibrium existence and core equivalence theorems for an infinite horizon economy with a measure space of consumers. These results are currently the focus of extensive studies by mathematical theorists, and are obtained by an application of an advanced mathematical concept called saturated (super-atomless) measure space.The second major change is the inclusion of a simple toy model of a liberal society which implements the difference principle proposed by J Rawls as a principle of distributive justice. This new section opens up a possibility to connect theoretical economics and political philosophy.Thirdly, the author presents the marginal cost pricing equilibrium and discusses welfare properties of the external increasing returns, which also belong to Marshall/ Pigou tradition of the Cambridge school.Finally, a new mathematical appendix treats basics of singular homology theory. Although the fixed point theorem is originally a theorem of algebraic topology, most economic students know its proof only in the context of the differentiable manifold theory presented by J Milnor. Considering the significance of the fixed point theorem and its playing a key role in general equilibrium theory, the purpose of this new appendix is to provide readers with the idea of a proof of Brower's fixed point theorem from the 'right place'.This volume will be helpful for graduate students and researchers of mathematical economics, game theory, and microeconomics.

This collection of essays on Verdoorn's Law - the relationship between the growth of industrial productivity and output - presents a number of comprehensive surveys and assessments of the vast literature available. The collection not only includes an English translation of Verdoorn's seminal article originally published in Italian, but also new empirical evidence for the Verdoorn Law and new developments in the theoretical modelling of cumulative causation.

This is an excerpt from the 4-volume dictionary of economics, a reference book which aims to define the subject of economics today. 1300 subject entries in the complete work cover the broad themes of economic theory. This extract concentrates on the topic of general equilibrium.

Presents a collection of research findings on topical issues in international trade theory and policy. This work deals with trade liberalization and outsourcing. It examines trading clubs and preferential trading agreements. It features six chapters on the various aspects of trade and aid.

"Traditional tools of analysis that focus on particular commodities or sectors, a particular time frame, and aggregate diverse socioeconomic groups are ill-suited to analyze the consequences of the economic reforms of the last ten years. This volume shows the greater power and relevance of applied general equilibrium methods." "Through discussion of several major policy issues - agricultural and food policy, economies of scale in production and the associated market imperfections, macrostabilization programs, and modeling intertemporal tradeoffs - the contributors present work representative of the major trends in applied general equilibrium modeling of developing-country issues. Policy analysis using a rich variety of static, recursive, and intertemporal dynamic models is illustrated with problems from a number of developing countries in Africa, Asia, and Latin America. The countries studied range widely in their institutional features, stages of development, and economic size."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.
