Provides theoretical and applied contributions connected by the methodological approach to the use of general equilibrium model.
This book emphasizes that a trading equilibrium is general rather than partial, and is often best modeled using dual or envelope functions.
The authors' model is the first large-scale computer simulation of the effects of changes in U.S. import quotas.
Theory of General Economic Equilibrium provides information pertinent to the general economic equilibrium theory. This book covers a variety of topics, including efficiency, economic systems analysis, welfare economics, and international trade. Organized into three parts encompassing eight chapters, this book begins with an overview of the theory of efficient production and growth where consumer preferences play a subordinate role. This text then examines that for the case where preferences satisfy appropriate conditions, efficiency theory is superseded as normative analysis by optimality theory. Other chapters consider the optimization of consumer preferences that leads to the decline of many families. This book discusses as well the existence of equilibrium, which is of importance to both normative and positive economics. The final chapter deals with the question of the speed with which the economic system attains its equilibrium state, which is assumed to be stationary. This book is a valuable resource for professional economists and advanced graduate students in economics.
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 book provides a hands-on introduction to computable general equilibrium (CGE) models, written at an accessible, undergraduate level.
"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.
While most standard economic models of international trade assume full employment, Carl Davidson and Steven Matusz have argued over the past two decades that this reliance on full-employment modeling is misleading and ill-equipped to tackle many important trade-related questions. This book brings together the authors' pioneering work in creating models that more accurately reflect the real-world connections between international trade and labor markets. The material collected here presents the theoretical and empirical foundations of equilibrium unemployment modeling, which the authors and their collaborators developed to give researchers and policymakers a more realistic picture of how international trade affects labor markets, and of how transnational differences in labor markets affect international trade. They address the shortcomings of standard models, describe the empirics that underlie equilibrium unemployment models, and illustrate how these new models can yield vital insights into the relationship between international trade and employment. This volume also includes an indispensable general introduction as well as concise section introductions that put the authors' work in context and reveal the thinking behind their ideas. Economists are only now realizing just how important these ideas are, making this book essential reading for researchers and students.
