Book Synopsis The Econometric Analysis of Non-Uniqueness in Rational Expectations Models by : L. Broze
Download or read book The Econometric Analysis of Non-Uniqueness in Rational Expectations Models written by L. Broze and published by Elsevier. This book was released on 2014-06-28 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to the econometric analysis of linear multivariate rational expectation models. It shows that the interpretation of multiplicity in terms of "new degrees of freedom" is consistent with a rigorous econometric reasoning. Non-uniqueness is the central theme of this book. Each chapter is concerned with a specific econometric aspect of rational expectations equilibria. The most constructive result lies in the possibility of an empirical determination of the equilibrium followed by the economy.
Book Synopsis Assessing Rational Expectations 2 by : Roger Guesnerie
Download or read book Assessing Rational Expectations 2 written by Roger Guesnerie and published by MIT Press. This book was released on 2005-02-18 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theoretical assessment of the Rational Expectations Hypothesis through subjecting a collection of economic models to an "eductive stability" test. The rational expectations hypothesis (REH) dominates economic modeling in areas ranging from monetary theory, macroeconomics, and general equilibrium to finance. In this book, Roger Guesnerie continues the critical analysis of the REH begun in his Assessing Rational Expectations: Sunspot Multiplicity and Economic Fluctuations, which dealt with the questions raised by multiplicity and its implications for a theory of endogenous fluctuations. This second volume emphasizes "eductive" learning: relying on careful reasoning, agents must deduce what other agents guess, a process that differs from the standard evolutionary learning experience in which agents make decisions about the future based on past experiences. A broad "eductive" stability test is proposed that includes common knowledge and results in a unique "rationalizable expectations equilibrium." This test provides the basis for Guesnerie's theoretical assessment of the plausibility of the REH's expectational coordination, emphasizing, for different categories of economic models, conditions for the REH's success or failure. Guesnerie begins by presenting the concepts and methods of the eductive stability analysis in selected partial equilibrium models. He then explores to what extent general equilibrium strategic complementarities interfere with partial equilibrium considerations in the formation of stable expectations. Guesnerie next examines two issues relating to eductive stability in financial market models, speculation and asymmetric price information. The dynamic settings of an infinite horizon model are then taken up, and particular standard and generalized saddle-path solutions are scrutinized. Guesnerie concludes with a review of general questions and some "cautious" remarks on the policy implications of his analysis.
Book Synopsis On Non-uniqueness in Rational Expectations Models by : Bennett T. McCallum
Download or read book On Non-uniqueness in Rational Expectations Models written by Bennett T. McCallum and published by . This book was released on 1981 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many macroeconomic models involving rational expect at ions give rise to an infinity of solution paths, even when the models are linear in all variables. Some writers have suggested that this non-uniqueness constitutes a serious weakness for the rational expectations hypothesis. One purpose of the present paper is to argue that the non-uniqueness in question is not properly attributable to the rationality hypothesis but, instead, is a general feature of dynamic models involving expectations. It is also argued that there typically exists, in a very wide class of linear rational expectations models, a single solution that excludes "bubble" or "bootstrap" effects ones that occur only because they are arbitrarily expected to occur. A systematic procedure for obtaining solutions free from such effects is introduced and discussed. In addition, this procedure is used to interpret and reconsider several prominent examples with solution multiplicities, including ones developed by Fischer Black and John B. Taylor.

Book Synopsis Methods of Macroeconomic Dynamics by : Stephen J. Turnovsky
Download or read book Methods of Macroeconomic Dynamics written by Stephen J. Turnovsky and published by MIT Press. This book was released on 2000 with total page 698 pages. Available in PDF, EPUB and Kindle. Book excerpt: Just as macroeconomic models describe the overall economy within a changing, or dynamic, framework, the models themselves change over time. In this text Stephen J. Turnovsky reviews in depth several early models as well as a representation of more recent models. They include traditional (backward-looking) models, linear rational expectations (future-looking) models, intertemporal optimization models, endogenous growth models, and continuous time stochastic models. The author uses examples from both closed and open economies. Whereas others commonly introduce models in a closed context, tacking on a brief discussion of the model in an open economy, Turnovsky integrates the two perspectives throughout to reflect the increasingly international outlook of the field. This new edition has been extensively revised. It contains a new chapter on optimal monetary and fiscal policy, and the coverage of growth theory has been expanded substantially. The range of growth models considered has been extended, with particular attention devoted to transitional dynamics and nonscale growth. The book includes cutting-edge research and unpublished data, including much of the author's own work.
Book Synopsis Imperfect Competition, Differential Information, and Microfoundations of Macroeconomics by : Kiyohiko G. Nishimura
Download or read book Imperfect Competition, Differential Information, and Microfoundations of Macroeconomics written by Kiyohiko G. Nishimura and published by Oxford University Press. This book was released on 1995 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume links a microeconomic model of imperfectly informed firms and unions in monopolistic competition to a general theory of wage- and price-setting in a macroeconomic model. The analysis is based on a profit maximization and rational behaviour and is thus in line with the newly emerged New Keynesian approach in its emphasis on the microeconomic foundation of macroeconomics. The volume goes on to explain three stylized facts in macroeconomics: nominal rigidity, real rigidity, and cost-oriented prices, presented in a coherent New Keynesian framework. The analysis also provides new insight into the role of competition in an economy with imperfectly and differentially informed firms. It shows that increased competition may increase nominal as well as real price rigidity and increased volatility of investment.
Book Synopsis Rational Expectations Econometrics by : Lars Peter Hansen
Download or read book Rational Expectations Econometrics written by Lars Peter Hansen and published by CRC Press. This book was released on 2019-09-05 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the core of the rational expectations revolution is the insight that economic policy does not operate independently of economic agents' knowledge of that policy and their expectations of the effects of that policy. This means that there are very complicated feedback relationships existing between policy and the behaviour of economic agents, and these relationships pose very difficult problems in econometrics when one tries to exploit the rational expectations insight in formal economic modelling. This volume consists of work by two rational expectations pioneers dealing with the "nuts and bolts" problems of modelling the complications introduced by rational expectations. Each paper deals with aspects of the problem of making inferences about parameters of a dynamic economic model on the basis of time series observations. Each exploits restrictions on an econometric model imposed by the hypothesis that agents within the model have rational expectations.
Book Synopsis Business Cycle Models with Indeterminacy by : Mark Weder
Download or read book Business Cycle Models with Indeterminacy written by Mark Weder and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three original models which explain business cycles as a result of self-fulfilling expectations are presented. The models are founded on the structure of dynamic general equilibrium theory. Market power and increasing returns to scale are introduced which allow indeterminancy of the Rational Expectations equilibria to be obtained. Unlike the majority of existing literature on this subject, the departures from perfect markets and constant returns presented in these models are very low and, more importantly, at a realistic level to achieve the respective results. It is demonstrated in all of the presented models that stylized facts of the business cycle can be reproduced.
Book Synopsis Applied General Equilibrium Modelling by : Henk Don
Download or read book Applied General Equilibrium Modelling written by Henk Don and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last decade or so, applied general equilibrium models have rapidly become a major tool for policy advice on issues regarding allocation and efficiency, most notably taxes and tariffs. This reflects the power of the general equilibrium approach to allocative questions and the capability of today's applied models to come up with realistic answers. However, it by no means implies that the theoretical, practical and empirical problems faced by researchers in applied modelling have all been solved in a satisfactory way. Rather, a promising field of research has been opened up, inviting theorists and practitioners to further explore and exploit its potential. The state of the art in applied general equilibrium modelling is reflected in this volume. The introductory Chapter (Part I) evaluates the use of economic modelling to address policy questions, and discusses the advantages and disadvantages of applied general equilibrium models. Three substantive issues are dealt with in Chapters 2-8: Tax Reform and Capital (Part II), Intertemporal Aspects and Expectations (Part III), and Taxes and the Labour Market (Part IV). While all parts contain results relevant for economic policy, it is clear that theory and applications for these areas are in different stages of development. We hope that this book will bring inspiration, insight and information to researchers, students and policy advisors.
Download or read book Robustness written by Lars Peter Hansen and published by Princeton University Press. This book was released on 2016-06-28 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: The standard theory of decision making under uncertainty advises the decision maker to form a statistical model linking outcomes to decisions and then to choose the optimal distribution of outcomes. This assumes that the decision maker trusts the model completely. But what should a decision maker do if the model cannot be trusted? Lars Hansen and Thomas Sargent, two leading macroeconomists, push the field forward as they set about answering this question. They adapt robust control techniques and apply them to economics. By using this theory to let decision makers acknowledge misspecification in economic modeling, the authors develop applications to a variety of problems in dynamic macroeconomics. Technical, rigorous, and self-contained, this book will be useful for macroeconomists who seek to improve the robustness of decision-making processes.
Book Synopsis Post Walrasian Macroeconomics by : David Colander
Download or read book Post Walrasian Macroeconomics written by David Colander and published by Cambridge University Press. This book was released on 2006-07-17 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macroeconomics is evolving in an almost dialectic fashion. The latest evolution is the development of a new synthesis that combines insights of new classical, new Keynesian and real business cycle traditions into a dynamic, stochastic general equilibrium (DSGE) model that serves as a foundation for thinking about macro policy. That new synthesis has opened up the door to a new antithesis, which is being driven by advances in computing power and analytic techniques. This new synthesis is coalescing around developments in complexity theory, automated general to specific econometric modeling, agent-based models, and non-linear and statistical dynamical models. This book thus provides the reader with an introduction to what might be called a Post Walrasian research program that is developing as the antithesis of the Walrasian DSGE synthesis.

Book Synopsis Analyses in Macroeconomic Modelling by : Andrew J. Hughes Hallett
Download or read book Analyses in Macroeconomic Modelling written by Andrew J. Hughes Hallett and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macroeconomic Modelling has undergone radical changes in the last few years. There has been considerable innovation in developing robust solution techniques for the new breed of increasingly complex models. Similarly there has been a growing consensus on their long run and dynamic properties, as well as much development on existing themes such as modelling expectations and policy rules. This edited volume focuses on those areas which have undergone the most significant and imaginative developments and brings together the very best of modelling practice. We include specific sections on (I) Solving Large Macroeconomic Models, (II) Rational Expectations and Learning Approaches, (III) Macro Dynamics, and (IV) Long Run and Closures. All of the contributions offer new research whilst putting their developments firmly in context and as such will influence much future research in the area. It will be an invaluable text for those in policy institutions as well as academics and advanced students in the fields of economics, mathematics, business and government. Our contributors include those working in central banks, the IMF, European Commission and established academics.

Book Synopsis The Representative Agent in Macroeconomics by : James E Hartley
Download or read book The Representative Agent in Macroeconomics written by James E Hartley and published by Routledge. This book was released on 2002-01-04 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rpresentative agent models have become a predominant means of studying the macroeconomy in modern economics without there being much discussion in the literature about their propriety or usefulness. This volume evaluates the use of these models in macroeconomics, examining the justifications for their use and concluding that representative agent models are neither a proper nor a particularly useful means of studying aggregate behaviour.
Book Synopsis Dynamic Macroeconomics with Imperfect Competition by : Leo Kaas
Download or read book Dynamic Macroeconomics with Imperfect Competition written by Leo Kaas and published by Springer Science & Business Media. This book was released on 1999-08-19 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis was stimulated throughout the time of my participation in a research project on Dynamic Macroeconomics, supported by the German Research Foundation (DFG). The starting point was the central question of how to integrate price setting firms in a dynamic disequilibrium model. Almost all recent literature on imperfect competition in macroeconomics applies the objective demand approach by assuming that firms know the true demand curve they are faced with. While this approach can be ap plied in temporary monetary equilibrium models, it proves inadequate for formulating price adjustment in a dynamic disequilibrium model, where it has to be replaced by the concept of subjective demand. Based on this distinction, the thesis starts out with a comparison of the concepts of subjective and objective demand in an abstract framework and surveys the literature on general equilibrium theory with imperfect competition. The objective demand approach is criticized not only on the grounds of its strong rationality requirements and existence problems, but also by the observation that it cannot be applied successfully to characterize determinate rational expectations equilibria in intertemporal macroeco nomics. Finally, price setting firms using subjective demand functions are integrated in a dynamic disequilibrium model in order to study mo nopolistic and oligopolistic price adjustment.

This book was released on 2016-10-04 with total page 770 pages. Available in PDF, EPUB and Kindle. Book excerpt: An indispensable survey of new developments and results in experimental economics When The Handbook of Experimental Economics first came out in 1995, the notion of economists conducting lab experiments to generate data was relatively new. Since then, the field has exploded. This second volume of the Handbook covers some of the most exciting new growth areas in experimental economics, presents the latest results and experimental methods, and identifies promising new directions for future research. Featuring contributions by leading practitioners, the Handbook describes experiments in macroeconomics, charitable giving, neuroeconomics, other-regarding preferences, market design, political economy, subject population effects, gender effects, auctions, and learning and the economics of small decisions. Contributors focus on key developments and report on experiments, highlighting the dialogue between experimenters and theorists. While most of the experiments consist of laboratory studies, the book also includes several chapters that report extensively on field experiments related to the subject area studied.
