General Equilibrium


Book Description

"This book focuses on the foundations of general equilibrium theory, more specifically on the existence, uniqueness, stability, optimality and comparative static properties of equilibrium states. It also explores the question of the empirical relevance of equilibrium states. It highlights a series of 'relationship conditions' which are essential for the existence of equilibrium, but appear in optimality results." -- PUBLISHER WEBSITE.




General Equilibrium


Book Description

Written by one of the key pioneers in the field, this book offers an accessible introduction to general equilibrium theory. Written for undergraduates taking courses in economic theory and modelling who have limited mathematical proficiency, the book fills a gap between forbidding technical expositions and the less rigorous elementary ones.




Model Building in Economics


Book Description

Concern about the role and the limits of modeling has heightened after repeated questions were raised regarding the dependability and suitability of the models that were used in the run-up to the 2008 financial crash. In this book, Lawrence Boland provides an overview of the practices of and the problems faced by model builders to explain the nature of models, the modeling process, and the possibility for and nature of their testing. In a reflective manner, the author raises serious questions about the assumptions and judgments that model builders make in constructing models. In making his case, he examines the traditional microeconomics-macroeconomics separation with regard to how theoretical models are built and used and how they interact, paying particular attention to the use of equilibrium concepts in macroeconomic models and game theory and to the challenges involved in building empirical models, testing models, and using models to test theoretical explanations.




General Equilibrium: Theory And Evidence


Book Description

General Equilibrium Theory studies the properties and operation of free market economies. The field is a response to a series of questions originally outlined by Leon Walras about the operation of markets and posed by Frank Hahn in the following way: ‘Does the pursuit of private interest, through a system of interconnected deregulated markets, lead not to chaos but to coherence — and if so, how is that achieved?’ This is always an apt question, but particularly so given the ‘Global Financial Crisis’ that emerged from the operation of market economies in the Americas and Europe in mid to late 2008.The answer that General Equilibrium Theory provides to the Walras-Hahn question is that, under certain conditions coherence is possible, while under certain other conditions chaos, in various forms, is likely to prevail. The conditionality of either outcome is not always well understood — neither by proponents of, or antagonists to, the ‘free market position’. Consequently, this book attempts to show something of what General Equilibrium Theory has to say about the wisdom or otherwise of always relying on ‘market forces’ to manage complex socio-economic systems.




Revisiting the Informal Sector


Book Description

This book provides insight into the diverse aspects of the informal sector, its role in the context of unemployment, child labor, globalization and environment, as well as its multi-faceted interaction with the other sectors of the economy.




A General Equilibrium Model of Sovereign Default and Business Cycles


Book Description

Emerging markets business cycle models treat default risk as part of an exogenous interest rate on working capital, while sovereign default models treat income fluctuations as an exogenous endowment process with ad-noc default costs. We propose instead a general equilibrium model of both sovereign default and business cycles. In the model, some imported inputs require working capital financing; default on public and private obligations occurs simultaneously. The model explains several features of cyclical dynamics around default triggers an efficiency loss as these inputs are replaced by imperfect substitutes; and default on public and private obligations occurs simultaneously. The model explains several features of cyclical dynamics around deraults, countercyclical spreads, high debt ratios, and key business cycle moments.




Advanced Microeconomic Theory


Book Description

This advanced economics text bridges the gap between familiarity with microeconomic theory and a solid grasp of the principles and methods of modern neoclassical microeconomic theory.




General Theory Of Employment , Interest And Money


Book Description

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




The Invisible Hand


Book Description

This study of the fundamental theoretical underpinnings of modern economies examines how economists define and categorize the market. It suggests that modeling a social science such as economics on the physical/mathematical sciences has created intractable problems, and that the basic structure of the theory needs rethinking.A meticulously researched work in the field of mathematical economics and pure theory, The Invisible Hand traces the evolution of general economic equilibrium theory in its rich interaction with the physical sciences over a period of more than 150 years. The authors discuss how the "invisible hand" that balances physical processes was inspiration and model for the creation of general economic equilibrium theory.Ingrao and Israel review fundamental concepts of the theory, showing how its early forms, strictly analogous to mechanical equilibrium, arose from the cultural atmosphere generated by Newtonianism and the French Enlightenment. They describe developments and changes in the theory from the work of Leon Walras and Vilfredo Pareto through restructuring by the Vienna group and John Von Neumann and the contributions of the Robbins group at the London School of Economics, to its current formulations in the work of Irving Fisher, Paul Samuelson, Kenneth Arrow, and Gerard Debreu.Concluding chapters survey the results obtained in attempts to deal with questions of the existence of equilibrium, its uniqueness, and the problem of global stability. Ingrao and Israel find that the theory has arrived at a dead end, which raises serious doubts about the internal consistency of the basic model.Bruna Ingrao is Associate Professor of Economics at the University of Sassari and Giorgio Israel is Associate Professor of Mathematics at the University of Rome.
