General Equilibrium Models of Monetary Economies: Studies in the Static Foundations of Monetary Theory is a collection of essays that addresses the integration of the theory of money and the theory of value by using a mathematical general equilibrium theory. The papers discuss monetary theory, microeconomic theory, bilateral trade, transactions costs, intertemporal allocation, and the value of money. The Arrow-Debreu model of Walrasian general equilibrium theory provides a framework to represent money as a device for facilitating trade among economic agents without the use of money as a medium of exchange and as a store of value. The essays analyze the rationale for using a medium of exchange, for using a store of value, and for holding of idle balances in equilibrium. The essays show that by explicit modeling of the structure and difficulties of trade, a powerful class of models which deny money and finance a role in the economy, has by itself shown to have provided the foundation for the structures of trade. The collection will prove helpful for economists, statistician, mathematicians, students or professors of economics and business.

A rigorous theory of money, credit, and bankruptcy in the context of a mixed economy, uniting Walrasian general equilibrium with macroeconomic dynamics and Schumpeterian innovation. This book offers a rigorous study of control, guidance, and coordination problems of an enterprise economy, with attention to the roles of money and financial institutions. The approach is distinctive in drawing on game theory, methods of physics and experimental gaming, and, more generally, a broader evolutionary perspective from the biological and behavioral sciences. The proposed theory unites Walrasian general equilibrium with macroeconomic dynamics and Schumpeterian innovation utilizing strategic market games. Problems concerning the meaning of rational economic behavior and the concept of solution are noted. The authors argue that process models of the economy can be built that are consistent with the general equilibrium system but become progressively more complex as new functions are added. Explicit embedding of the economy within the framework of government and society provides a natural, both formal and informal, control system. The authors describe how to build and analyze multistate models with simple assumptions about behavior, and develop a general modeling methodology for the construction of models as playable games.

This book deals mainly with what can be described as the general-equilibrium approach to monetary theory. The author does not attempt an encyclopaedic treatment, rather Gale investigates the central problems and ideas in the development of topical monetary theory. The first part of the book - technically the easier - deals with questions which will be recognized as falling within the traditional field of (macroeconomic) monetary theory, although the treatment is unflaggingly microeconomic. The second part is less conventional, dealing with the general equilibrium theory of money in a fundamental way.

General Equilibrium Theory: An Introduction treats the classic Arrow-Debreu general equilibrium model in a form accessible to graduate students and advanced undergraduates in economics and mathematics. Topics covered include mathematical preliminaries, households and firms, existence of general equilibrium, Pareto efficiency of general equilibrium, the First and Second Fundamental Theorems of Welfare Economics, the core and core convergences, future markets over time and contingent commodity markets under uncertainty. Demand, supply, and excess demand appear first as (point-valued) functions, then optionally as (set-valued) correspondences. The mathematics presented (with elementary proofs of the theorems) includes a real analysis, the Brouwer fixed point theorem, and separating and supporting hyperplane theorems. Optional chapters introduce the existence of equilibrium with set-valued supply and demand, the mathematics of upper and lower hemicontinuous correspondences, and the Kakutani fixed point theorem. The treatment emphasizes clarity and accessibility to the student through use of examples and intuition.

The purpose of this manual is to contribute to and facilitate the use of computable general equilibrium (CGE) models in the analysis of issues related to food policy in developing countries. The volume includes a detailed presentation of a static “standard” CGE model and its required database and incorporates features of particular importance in developing countries. The manual discusses the implementation of the model in GAMS and is accompanied by a CD-ROM that includes the GAMS software (free demo system), the GAMS input files for the model, sample databases, simulations, solution reports, and a social accounting matrix (SAM) aggregation program. Although the volume provides a standardized framework for analysis, the analyst is not forced to make “one-size-fits-all” assumptions. The GAMS code is written to give the analyst considerable flexibility in model specification.

John Maynard Keynes is the great British economist of the twentieth century whose hugely influential work The General Theory of Employment, Interest and * is undoubtedly the century's most important book on economics--strongly influencing economic theory and practice, particularly with regard to the role of government in stimulating and regulating a nation's economic life. Keynes's work has undergone significant revaluation in recent years, and "Keynesian" views which have been widely defended for so long are now perceived as at odds with Keynes's own thinking. Recent scholarship and research has demonstrated considerable rivalry and controversy concerning the proper interpretation of Keynes's works, such that recourse to the original text is all the more important. Although considered by a few critics that the sentence structures of the book are quite incomprehensible and almost unbearable to read, the book is an essential reading for all those who desire a basic education in economics. The key to understanding Keynes is the notion that at particular times in the business cycle, an economy can become over-productive (or under-consumptive) and thus, a vicious spiral is begun that results in massive layoffs and cuts in production as businesses attempt to equilibrate aggregate supply and demand. Thus, full employment is only one of many or multiple macro equilibria. If an economy reaches an underemployment equilibrium, something is necessary to boost or stimulate demand to produce full employment. This something could be business investment but because of the logic and individualist nature of investment decisions, it is unlikely to rapidly restore full employment. Keynes logically seizes upon the public budget and government expenditures as the quickest way to restore full employment. Borrowing the * to finance the deficit from private households and businesses is a quick, direct way to restore full employment while at the same time, redirecting or siphoning
