Download or read book Risk and Ambiguity in Models of Business Cycles written by David Backus and published by . This book was released on 2014 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: We inject aggregate uncertainty -- risk and ambiguity -- into an otherwise standard business cycle model and describe its consequences. We find that increases in uncertainty generally reduce consumption, but they do not account, in this model, for either the magnitude or the persistence of the most recent recession. We speculate about extensions that might do better along one or both dimensions.

Book excerpt: This paper considers business cycle models with agents who dislike both risk and ambiguity (Knightian uncertainty). Ambiguity aversion is described by recursive multiple priors preferences that capture agents' lack of confidence in probability assessments. While modeling changes in risk typically requires higher-order approximations, changes in ambiguity in our models work like changes in conditional means. Our models thus allow for uncertainty shocks but can still be solved and estimated using first-order approximations. In our estimated medium-scale DSGE model, a loss of confidence about productivity works like 'unrealized' bad news. Time-varying confidence emerges as a major source of business cycle fluctuations.

Download or read book Business Cycles written by Victor Zarnowitz and published by University of Chicago Press. This book was released on 2007-11-01 with total page 613 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the most complete collection available of the work of Victor Zarnowitz, a leader in the study of business cycles, growth, inflation, and forecasting.. With characteristic insight, Zarnowitz examines theories of the business cycle, including Keynesian and monetary theories and more recent rational expectation and real business cycle theories. He also measures trends and cycles in economic activity; evaluates the performance of leading indicators and their composite measures; surveys forecasting tools and performance of business and academic economists; discusses historical changes in the nature and sources of business cycles; and analyzes how successfully forecasting firms and economists predict such key economic variables as interest rates and inflation.
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.
Download or read book Business Cycles and Equilibrium written by Fischer Black and published by John Wiley & Sons. This book was released on 2009-11-02 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: An updated look at what Fischer Black's ideas on business cycles and equilibrium mean today Throughout his career, Fischer Black described a view of business fluctuations based on the idea that a well-developed economy will be continually in equilibrium. In the essays that constitute this book, which is one of only two books Black ever wrote, he explores this idea thoroughly and reaches some surprising conclusions. With the newfound popularity of quantitative finance and risk management, the work of Fischer Black has garnered much attention. Business Cycles and Equilibrium-with its theory that economic and financial markets are in a continual equilibrium-is one of his books that still rings true today, given the current economic crisis. This Updated Edition clearly presents Black's classic theory on business cycles and the concept of equilibrium, and contains a new introduction by the person who knows Black best: Perry Mehrling, author of Fischer Black and the Revolutionary Idea of Finance (Wiley). Mehrling goes inside Black's life to uncover what was occurring during the time Black wrote Business Cycles and Equilibrium, while also shedding light on what Black would make of today's financial and economic meltdown and how he would best advise to move forward. The essays within this book reach some interesting conclusions concerning the role of equilibrium in a developed economy Warns about the use and abuse of modeling Explains the risky business of risk in a straightforward and accessible style Contains chapters dedicated to "the effects of uncontrolled banking," "the trouble with econometric models," and "the effects of noise on investing" Includes commentary on Black's life and work at the time Business Cycles and Equilibrium was written as well as insight as to what Black would make of the current financial meltdown Engaging and informative, the Updated Edition of Business Cycles and Equilibrium will give you a better understanding of what is really going on during these uncertain and volatile financial times.
Download or read book A General Equilibrium Model of Sovereign Default and Business Cycles written by Mr.Enrique G. Mendoza and published by International Monetary Fund. This book was released on 2011-07-01 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Models of Business Cycles written by Robert E. Lucas, Jr. and published by Wiley-Blackwell. This book was released on 1991-01-08 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decade macroeconomic theory has undergone a remarkable transformation. At the forefront has been the "rational expectations revolution," and this school's most brilliant exponent is Robert E. Lucas. In this elegant and relatively non-technical survey, Lucas reviews the nature and consequences of recent developments in monetary and business cycle theory. He discusses the usefulness of alternative models in determining the effects of economic policy on consumption streams and individual welfare. Drawing on a specific model of aggregate activity which represents the current frontier in business cycle research, he then examines the contemporary theory of unemployment. Finally and most controversially, he explores the role of monetary disturbances.
Download or read book Frontiers of Business Cycle Research written by Thomas F. Cooley and published by Princeton University Press. This book was released on 2020-09-01 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the most revolutionary and productive areas of economic research over the last two decades, modern business cycle theory is finally made accessible to students and professionals in this rigorous, unified, introductory volume. This theory starts with the view that growth and fluctuations are not distinct phenomena to be studied separately--and that business cycles result from shocks (such as the availability of new technologies), which regularly affect most economies. The unifying theme of this book is the use of the neoclassical growth framework to study the economic fluctuations associated with the business cycle. Presenting recent advances in dynamic economic theory and computational methods--with emphasis on the construction of equilibrium paths for simple artificial economies--leading experts orient readers in the quantitative study of aggregate fluctuations and apply its concepts to key issues in macroeconomics and business cycle theory. This volume covers such issues as the aggregate labor market, the role of the household sector, the role of money, the behavior of asset markets, non-Walrasian economies, monopolistically competitive economies, international business cycles, and the design of economic policies. The contributors are David Backus, V. V. Chari, Lawrence Christiano, Thomas F. Cooley, Jean-Pierre Danthine, John Donaldson, Jeremy Greenwood, Gary D. Hansen, Patrick Kehoe, Finn Kydland, Edward C. Prescott, Richard Rogerson, Julio Rotemberg, Geert Rouwenhorst, José-Víctor Ríos-Rull, Michael Woodford, and Randall Wright.
Download or read book Identifying Ambiguity Shocks in Business Cycle Models Using Survey Data written by Anmol Bhandari and published by . This book was released on 2016 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: We develop a framework to analyze economies with agents facing time-varying concerns for model misspecification. These concerns lead agents to interpret economic outcomes and make decisions through the lens of a pessimistically biased 'worst-case' model. We combine survey data and implied theoretical restrictions on the relative magnitudes and comovement of forecast biases across macroeconomic variables to identify ambiguity shocks as exogenous fluctuations in the worst-case model. Our solution method delivers tractable linear approximations that preserve the effects of time-varying ambiguity concerns and permit estimation using standard Bayesian techniques. Applying our framework to an estimated New-Keynesian business cycle model with frictional labor markets, we find that ambiguity shocks explain a substantial portion of the variation in labor market quantities.
Download or read book Real Business Cycle Models in Economics written by Warren Young and published by Routledge. This book was released on 2014-01-10 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to describe the intellectual process by which Real Business Cycle models were developed. The approach taken focuses on the core elements in the development of RBC models: (i) building blocks, (ii) catalysts, and (iii) meta-syntheses. This is done by detailed examination of all available unpublished variorum drafts of the key papers in the RBC story, so as to determine the origins of the ideas. The analysis of the process their discovery is then set out followed by explanations of the evolution and dissemination of the models, from first generation papers through full blown research programs. This is supplemented by interviews and correspondence with the individuals who were at the center of the development of RBC models, such as Kydland, Prescott, Long, Plosser, King, Lucas and Barro, among others. This book gets stright to the heart of the debates surrounding RBC models and as such contributes to a real assessment of their impact on modern macroeconomics. The volume, therefore, will interest all scholars looking at macroeconomics as well as historians of economic thought more generally.
