This volume is intended to provide a survey of thought about exchange-rate determination as it emerged in the decade of the 1970s. This survey differs from many, however, in that the field itself is in a state of rapid change. Understanding the changes and the reasons for them is therefore essential if the reader is to have a basis for understanding future advances in knowledge and the further evolution of the system. The survey is also intended to reach non-specialist professional economists whose balance-of-payments theory was learned before the 1970s, as well as to provide graduate students and advanced undergraduates with an up-to-date account of the field. In most respects, the theory of exchange-rate determination is based upon an analytical structure equivalent to that analyzing the determinants of the balance of payments under fixed exchange rates. The difference is that the shifts in excess demand for foreign exchange lead to quantity adjustments under fixed rates and price adjustment under flexible rates. Thus, attention turns first to exchange-rate, or balance-of-payments, determination. Thereafter formal analyses of differences and similarities between the functioning of the alternative systems are considered, reflecting the focus of the profession and the mainstream of research of this period.

This is the first full-length survey of current work which examines the compatibility of microeconomics and macroeconomics. Its particular distinction is that it makes accessible, to non-specialists, those extensive modern refinements of general equilibrium theory which are linked to macroeconomics and monetary theory. Part I traces the development and interlocking nature of two scientific research prgrams, macroeconomics and neo-Walrasian analysis. The five chapters in this part examine general equilibrium theory, Keynes' contribution, the 'neoclassical synthesis', and the Clower-Leijonhufvud contributions to questions of systemic coordination. The four chapters of Part II place recent work on the micro-foundations of macroeconomics within a taxonomic scheme of Walrasian equilibrium, Walrasian disequilibrium, Edgeworthian equilibrium, and Edgeworthian disequilibrium. Part III, a single chapter, provides an overview of the subject and ventures some conclusions.

A survey of the new theories of inflation that have developed over the past two decades in response to the inflationary pressures experienced by Western countries examines the shifting debate from explaining inflation as a "causal" process to explaining its increase as a result of constantly changing expectations.

The aim of this book is to make more widely available a body of recent research activity that has become known as applied general equilibrium analysis. The central idea underlying this work is to convert the Walrasian general equilibrium structure (formalized in the 1950s by Kenneth Arrow, Gerard Debreu and others) from an abstract representation of an economy into realistic models of actual economies. Numerical, empirically based general equilibrium models can then be used to evaluate concrete policy options by specifying production and demand parameters and incorporating data reflective of real economies. Shoven and Whalley describe all aspects of developing applied general equilibrium models, including developing an appropriate equilibrium structure, calibrating the model, compiling counterfactual equilibria, and interpreting results. The authors contend that the Walrasian general equilibrium model provides an ideal framework for appraising the effects of policy changes on resource allocation, assessing who gains and who loses, and the policy impacts not well covered by empirical macro models. The applications in the book illustrate a number of ways in which fresh insights are provided in longstanding policy controversies.

Considered the cutting edge of microeconomic theory in the 1970s, natural monopoly research remains an active and fertile field. Policy makers and regulators have begun to implement entry and pricing policies that are based on theoretical and empirical analyses. This book develops a comprehensive framework for analyzing natural monopoly. The authors first present a historical overview of regulatory economics, followed by analyses of optimal pricing and investment for single- and multiproduct natural monopolies. Topics covered include cost and demand structures, efficiency impacts of linear and multipart pricing, peak-load pricing, capacity determination, and the sustainability of natural monopolies. After a survey and analysis of natural monopoly regulation in practice, the links between technological change and regulation are identified. The book concludes with a discussion of the alternatives to traditional regulation, including public ownership, franchise schemes, quality regulation, and new incentive systems. Throughout the book, issues from the telecommunications and energy industries are used to illustrate key points. Its integrated framework will make it useful to academic economists, regulatory analysts, business researchers, and advanced students of public utility economics.

An important research programme has developed in economics that extends neo-classical economic theory in order to examine the effects of institutions on economic behaviour. The body of work emerging from this line of inquiry includes contributions from various branches of economic theory, such as the economics of property rights, the theory of the firm, cliometrics and law and economics. This book is a comprehensive survey of this research programme which the author terms 'neoinstitutional economics'. The author proposes a unified approach to this research, integrating the work of various contributors and emphasising the common principles of inquiry that tie the work together. The theoretical discussion is accompanied by empirical studies dealing with a range of institutions and economic systems. This book will serve as the primary resource for economists and students who want to learn about this important branch of economic theory.

This book is an examination of the nature of economic explanation. The opening chapters introduce current thinking in the philosophy of science and review the literature on methodology. Professor Blaug then turns to the troublesome question of the logical status of welfare economics, giving the reader an understanding of the outstanding issues in the methodology of economics. This is followed by a series of case studies of leading economic controversies, which shows how controversies in economics may be illuminated by paying attention to questions of methodology. A final chapter draws the strands together and gives the author's view of what is wrong with modern economics. This book is a revised and updated edition of a classic work on the methodology of economics, in which Professor Blaug develops his discussion of the latest developments in macroeconomics, general equilibrium theory and international trade theory. A new section on the rationality postulate is also added.

This book describes and evaluates the literature on exchange rate economics. It provides a wide-ranging survey, with background on the history of international monetary regimes and the institutional characteristics of foreign exchange markets, an overview of the development of conceptual and empirical models of exchange rate behavior, and perspectives on the key issues that policymakers confront in deciding whether, and how, to try to stabilize exchange rates. The treatment of most topics is reasonably compact, with extensive references to the literature for those desiring to pursue individual topics further. The level of exposition is relatively easy to comprehend and the chapters are written at a level intelligible to first-year graduate students or advanced undergraduates. The book will enlighten both students and policymakers, and should also serve as a valuable reference for many research economists.

Economists have developed models in which individuals form expectations of key variables in a 'rational' manner such that these expectations are consistent with actual economic environments. Professor Sheffrin first explores the logical foundation of the concept and the case for employing it in economic analysis. Subsequent chapters investigate its use in macroeconomics, financial markets, and microeconomics. A final chapter assesses its impact on theoretical and empirical work in economics and policy arenas. The author argues that while rational expectations are still central to macroeconomic policy debates, fully workable models have not yet been devised, and offers reasons for the lack of practical and conceptual progress. All chapters of the second edition have been revised or expanded. New sections inter alia include material on learning, the rationality of reported expectations, alternative recent developments explicitly or implicitly using rational expectations, new tests of the Lucas critique, and models of noise trading. The book is written in a non-technical fashion for beginning graduate students and non-specialists.
