Available in PDF, EPUB and Kindle. Book excerpt: This study explores the macroeconomic implications of adaptive expectations in a standard real business cycle model. When rational expectations are replaced by adaptive expectations, we show that the self-confirming equilibrium is the same as the steady-state rational expectations equilibrium for all admissible parameters but that dynamics around the steady state are substantially different between the two equilibria. The differences are driven mainly by the dampened wealth effect and the strengthened intertemporal substitution effect, not by the escapes emphasized by Williams (2003). As a result, adaptive expectations can be an important source of frictions that amplify and propagate technology shocks and seem promising for generating plausible labor market dynamics.

This book was released on 2004-12-01 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our answer: Not so well. We reached that conclusion after reviewing recent research on the role of technology as a source of economic fluctuations. The bulk of the evidence suggests a limited role for aggregate technology shocks, pointing instead to demand factors as the main force behind the strong positive comovement between output and labor input measures.

Available in PDF, EPUB and Kindle. Book excerpt: This book originated from a 2010 conference marking the fortieth anniversary of the publication of the landmark "Phelps volume," Microeconomic Foundations of Employment and Inflation Theory, a book that is often credited with pioneering the currently dominant approach to macroeconomic analysis. However, in their provocative introductory essay, Roman Frydman and Edmund Phelps argue that the vast majority of macroeconomic and finance models developed over the last four decades derailed, rather than built on, the Phelps volume's "microfoundations" approach. Whereas the contributors to the 1970 volume recognized the fundamental importance of according market participants' expectations an autonomous role, contemporary models rely on the rational expectations hypothesis (REH), which rules out such a role by design. The financial crisis that began in 2007, preceded by a spectacular boom and bust in asset prices that REH models implied could never happen, has spurred a quest for fresh approaches to macroeconomic analysis. While the alternatives to REH presented in Rethinking Expectations differ from the approach taken in the original Phelps volume, they are notable for returning to its major theme: understanding aggregate outcomes requires according expectations an autonomous role. In the introductory essay, Frydman and Phelps interpret the various efforts to reconstruct the field--some of which promise to chart its direction for decades to come. The contributors include Philippe Aghion, Sheila Dow, George W. Evans, Roger E. A. Farmer, Roman Frydman, Michael D. Goldberg, Roger Guesnerie, Seppo Honkapohja, Katarina Juselius, Enisse Kharroubi, Blake LeBaron, Edmund S. Phelps, John B. Taylor, Michael Woodford, and Gylfi Zoega.

Download or read book Expectations Learning and Business Cycle Fluctuations written by Stefano Eusepi and published by . This book was released on 2008 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This paper develops a theory of expectations-driven business cycles based on learning. Agents have incomplete knowledge about how market prices are determined and shifts in expectations of future prices affect dynamics. In a real business cycle model, the theoretical framework amplifies and propagates technology shocks. Improved correspondence with data arises from dynamics in beliefs being themselves persistent and because they generate strong intertemporal substitution effects in consumption and leisure. Output volatility is comparable with a rational expectations analysis with a standard deviation of technology shock that is 20 percent smaller, and has substantially more volatility in investment and hours. Persistence in these series is captured, unlike in standard models. Inherited from real business cycle theory, the benchmark model suffers a comovement problem between consumption, hours, output and investment. An augmented model that is consistent with expectations-driven business cycles, in the sense of Beaudry and Portier (2006), resolves these counterfactual predictions"--National Bureau of Economic Research web site

Download or read book Inflation Expectations written by Peter J. N. Sinclair and published by Routledge. This book was released on 2009-12-16 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inflation is regarded by the many as a menace that damages business and can only make life worse for households. Keeping it low depends critically on ensuring that firms and workers expect it to be low. So expectations of inflation are a key influence on national economic welfare. This collection pulls together a galaxy of world experts (including Roy Batchelor, Richard Curtin and Staffan Linden) on inflation expectations to debate different aspects of the issues involved. The main focus of the volume is on likely inflation developments. A number of factors have led practitioners and academic observers of monetary policy to place increasing emphasis recently on inflation expectations. One is the spread of inflation targeting, invented in New Zealand over 15 years ago, but now encompassing many important economies including Brazil, Canada, Israel and Great Britain. Even more significantly, the European Central Bank, the Bank of Japan and the United States Federal Bank are the leading members of another group of monetary institutions all considering or implementing moves in the same direction. A second is the large reduction in actual inflation that has been observed in most countries over the past decade or so. These considerations underscore the critical – and largely underrecognized - importance of inflation expectations. They emphasize the importance of the issues, and the great need for a volume that offers a clear, systematic treatment of them. This book, under the steely editorship of Peter Sinclair, should prove very important for policy makers and monetary economists alike.

This book was released on 2012-01-06 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: A crucial challenge for economists is figuring out how people interpret the world and form expectations that will likely influence their economic activity. Inflation, asset prices, exchange rates, investment, and consumption are just some of the economic variables that are largely explained by expectations. Here George Evans and Seppo Honkapohja bring new explanatory power to a variety of expectation formation models by focusing on the learning factor. Whereas the rational expectations paradigm offers the prevailing method to determining expectations, it assumes very theoretical knowledge on the part of economic actors. Evans and Honkapohja contribute to a growing body of research positing that households and firms learn by making forecasts using observed data, updating their forecast rules over time in response to errors. This book is the first systematic development of the new statistical learning approach. Depending on the particular economic structure, the economy may converge to a standard rational-expectations or a "rational bubble" solution, or exhibit persistent learning dynamics. The learning approach also provides tools to assess the importance of new models with expectational indeterminacy, in which expectations are an independent cause of macroeconomic fluctuations. Moreover, learning dynamics provide a theory for the evolution of expectations and selection between alternative equilibria, with implications for business cycles, asset price volatility, and policy. This book provides an authoritative treatment of this emerging field, developing the analytical techniques in detail and using them to synthesize and extend existing research.

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 Expectations Anchoring and Inflation Persistence written by Mr.Rudolfs Bems and published by International Monetary Fund. This book was released on 2018-12-11 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the sources of inflation persistence is crucial for monetary policy. This paper provides an empirical assessment of the influence of inflation expectations' anchoring on the persistence of inflation. We construct a novel index of inflation expectations' anchoring using survey-based inflation forecasts for 45 economies starting in 1989. We then study the response of consumer prices to terms-of-trade shocks for countries with flexible exchange rates. We find that these shocks have a significant and persistent effect on consumer price inflation when expectations are poorly anchored. By contrast, inflation reacts by less and returns quickly to its pre-shock level when expectations are strongly anchored.

Download or read book Hysteresis and Business Cycles written by Ms.Valerie Cerra and published by International Monetary Fund. This book was released on 2020-05-29 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, economic growth and business cycles have been treated independently. However, the dependence of GDP levels on its history of shocks, what economists refer to as “hysteresis,” argues for unifying the analysis of growth and cycles. In this paper, we review the recent empirical and theoretical literature that motivate this paradigm shift. The renewed interest in hysteresis has been sparked by the persistence of the Global Financial Crisis and fears of a slow recovery from the Covid-19 crisis. The findings of the recent literature have far-reaching conceptual and policy implications. In recessions, monetary and fiscal policies need to be more active to avoid the permanent scars of a downturn. And in good times, running a high-pressure economy could have permanent positive effects.

Download or read book Knowledge Information and Expectations in Modern Macroeconomics written by Philippe Aghion and published by Princeton University Press. This book was released on 2021-01-12 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Macroeconomics would not be what it is today without Edmund Phelps. This book assembles the field's leading figures to highlight the continuing influence of his ideas from the past four decades. Addressing the most important current debates in macroeconomic theory, it focuses on the rates at which new technologies arise and information about markets is dispersed, information imperfections, and the heterogeneity of beliefs as determinants of an economy's performance. The contributions, which represent a breadth of contemporary theoretical approaches, cover topics including the real effects of monetary disturbances, difficulties in expectations formation, structural factors in unemployment, and sources of technical progress. Based on an October 2001 conference honoring Phelps, this incomparable volume provides the most comprehensive and authoritative account in years of the present state of macroeconomics while also pointing to its future.

Available in PDF, EPUB and Kindle. Book excerpt: Find the Leading Edge in a Disrupted World. Planning our response to disruption seems impossible. Most new and emerging technologies have been in development for decades, but as soon as they land on our doorstep, they inspire “the shock of the new.” How do you, as a learning professional, prepare for what you don’t know is coming? How do you judge what is important and what is just a fad? In Shock of the New: The Challenge and Promise of Emerging Learning Technologies, Chad Udell and Gary Woodill create a new framework for anticipating emerging learning technologies, outlining six key perspectives you should consider with any new technology. They examine some of the day’s most commonly discussed emerging technologies and pose the questions that will point the way to your own strategy. These insights aren’t limited to specific applications; they give you an approach you can apply to any new tech coming your way, so you’re always braced for the shock of the new. Udell and Woodill optimistically point out that emerging technologies will help us make sense of our increasingly complex world; many more changes will occur over the next decade, so buckle up! What was once science fiction has just become real—and now is your opportunity to be on the leading edge.
