Book Synopsis Information Rigidities by : Jonas Dovern
Download or read book Information Rigidities written by Jonas Dovern and published by International Monetary Fund. This book was released on 2014-02-12 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: We study forecasts for real GDP growth using a large panel of individual forecasts from 36 advanced and emerging economies during 1989–2010. We show that the degree of information rigidity in average forecasts is substantially higher than that in individual forecasts. Individual level forecasts are updated quite frequently, a behavior more in line “noisy” information models (Woodford, 2002; Sims, 2003) than with the assumptions of the sticky information model (Mankiw and Reis, 2002). While there are cross-country variations in information rigidity, there is no systematic difference between advanced and emerging economies.

This book was released on 2013-02-27 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: We examine the behavior of forecasts for real GDP growth using a large panel of individual forecasts from 30 advanced and emerging economies during 1989–2010. Our main findings are as follows. First, our evidence does not support the validity of the sticky information model (Mankiw and Reis, 2002) for describing the dynamics of professional growth forecasts. Instead, the empirical evidence is more in line with implications of "noisy" information models (Woodford, 2002; Sims, 2003). Second, we find that information rigidities are more pronounced in emerging economies than advanced economies. Third, there is evidence of nonlinearities in forecast smoothing. It is less pronounced in the tails of the distribution of individual forecast revisions than in the central part of the distribution.
Book Synopsis Information Rigidity and the Expectations Formation Process by : Mr.Olivier Coibion
Download or read book Information Rigidity and the Expectations Formation Process written by Mr.Olivier Coibion and published by International Monetary Fund. This book was released on 2012-12-20 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: We propose a new approach to test the full-information rational expectations hypothesis which can identify whether rejections of the arise from information rigidities. This approach quantifies the economic significance of departures from the and the underlying degree of information rigidity. Applying this approach to U.S. and international data of professional forecasters and other agents yields pervasive evidence consistent with the presence of information rigidities. These results therefore provide a set of stylized facts which can be used to calibrate imperfect information models. Finally, we document evidence of state-dependence in the expectations formation process.
Book Synopsis Information Rigidity in Growth Forecasts by : Ms.Natalia T. Tamirisa
Download or read book Information Rigidity in Growth Forecasts written by Ms.Natalia T. Tamirisa and published by International Monetary Fund. This book was released on 2011-06-01 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: We document information rigidity in forecasts for real GDP growth in 46 countries over the past two decades. We investigate: (i) if rigidities are lower around turning points in the economy, such as in times of recessions and crises; (ii) if rigidities differ across countries, particularly between advanced countries and emerging markets; and (iii) how quickly forecasters incorporate news about growth in other countries into their growth forecasts, with a focus on how advanced countries‘ growth forecasts incorporate news about emerging market growth and vice versa.
Book Synopsis Lectures on Formal and Rigid Geometry by : Siegfried Bosch
Download or read book Lectures on Formal and Rigid Geometry written by Siegfried Bosch and published by Springer. This book was released on 2014-08-22 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this work is to offer a concise and self-contained 'lecture-style' introduction to the theory of classical rigid geometry established by John Tate, together with the formal algebraic geometry approach launched by Michel Raynaud. These Lectures are now viewed commonly as an ideal means of learning advanced rigid geometry, regardless of the reader's level of background. Despite its parsimonious style, the presentation illustrates a number of key facts even more extensively than any other previous work. This Lecture Notes Volume is a revised and slightly expanded version of a preprint that appeared in 2005 at the University of Münster's Collaborative Research Center "Geometrical Structures in Mathematics".

Book Synopsis Asset Purchase Programs in European Emerging Markets by : Mr. Marco Arena
Download or read book Asset Purchase Programs in European Emerging Markets written by Mr. Marco Arena and published by International Monetary Fund. This book was released on 2021-09-24 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several emerging market central banks in Europe deployed asset purchase programs (APPs) amid the 2020 pandemic. The common main goals were to address market dysfunction and impaired monetary transmission, distinct from the quantitative easing conducted by major advanced economy central banks. Likely reflecting the global nature of the crisis, these APPs defied the traditional emerging market concern of destabilizing the exchange rate or inflation expectations and instead alleviated markets successfully. We uncover some evidence that APPs in European emerging markets stabilized government bond markets and boosted equity prices, with no indication of exchange rate pressure. Examining global and domestic factors that could limit the usability of APPs, in the event of renewed market dysfunction we see a potential scope for scaling up APPs in most European emerging markets that used APPs during the pandemic, provided that they remain consistent with the primary objective of monetary policy and keep a safe distance from the risk of fiscal dominance. As central banks in the region move towards monetary policy tightening, the tapering, ending, and unwinding of APPs must also be carefully considered. Clear and transparent communication is critical at each step of the process, from the inception to the closure of APPs, particularly when a large shock hits and triggers a major policy shift.

Book Synopsis Understanding Inflation and the Implications for Monetary Policy by : Jeff Fuhrer
Download or read book Understanding Inflation and the Implications for Monetary Policy written by Jeff Fuhrer and published by MIT Press. This book was released on 2009-09-11 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current perspectives on the Phillips curve, a core macroeconomic concept that treats the relationship between inflation and unemployment. In 1958, economist A. W. Phillips published an article describing what he observed to be the inverse relationship between inflation and unemployment; subsequently, the “Phillips curve” became a central concept in macroeconomic analysis and policymaking. But today's Phillips curve is not the same as the original one from fifty years ago; the economy, our understanding of price setting behavior, the determinants of inflation, and the role of monetary policy have evolved significantly since then. In this book, some of the top economists working today reexamine the theoretical and empirical validity of the Phillips curve in its more recent specifications. The contributors consider such questions as what economists have learned about price and wage setting and inflation expectations that would improve the way we use and formulate the Phillips curve, what the Phillips curve approach can teach us about inflation dynamics, and how these lessons can be applied to improving the conduct of monetary policy.

Book Synopsis Handbook of Macroeconomics by : John B. Taylor
Download or read book Handbook of Macroeconomics written by John B. Taylor and published by Elsevier. This book was released on 2016-11-12 with total page 3009 pages. Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Macroeconomics Volumes 2A and 2B surveys major advances in macroeconomic scholarship since the publication of Volume 1 (1999), carefully distinguishing between empirical, theoretical, methodological, and policy issues, including fiscal, monetary, and regulatory policies to deal with crises, unemployment, and economic growth. As this volume shows, macroeconomics has undergone a profound change since the publication of the last volume, due in no small part to the questions thrust into the spotlight by the worldwide financial crisis of 2008. With contributions from the world's leading macroeconomists, its reevaluation of macroeconomic scholarship and assessment of its future constitute an investment worth making. - Serves a double role as a textbook for macroeconomics courses and as a gateway for students to the latest research - Acts as a one-of-a-kind resource as no major collections of macroeconomic essays have been published in the last decade - Builds upon Volume 1 by using its section headings to illustrate just how far macroeconomic thought has evolved
Book Synopsis Rigidity Theory and Applications by : M.F. Thorpe
Download or read book Rigidity Theory and Applications written by M.F. Thorpe and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although rigidity has been studied since the time of Lagrange (1788) and Maxwell (1864), it is only in the last twenty-five years that it has begun to find applications in the basic sciences. The modern era starts with Laman (1970), who made the subject rigorous in two dimensions, followed by the development of computer algorithms that can test over a million sites in seconds and find the rigid regions, and the associated pivots, leading to many applications. This workshop was organized to bring together leading researchers studying the underlying theory, and to explore the various areas of science where applications of these ideas are being implemented.
Book Synopsis Advances in Macroeconomic Theory by : J. Drèze
Download or read book Advances in Macroeconomic Theory written by J. Drèze and published by Springer. This book was released on 2001-08-02 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leading world scholars analyze a range of specific departures from general equilibrium theory which have significant implications for the macroeconomic analysis of both developed and developing economies. Jacques Drèze considers uncertainty and incomplete markets and Nobel Laureate Robert Solow relates growth theory to the macroeconomic framework. Other issues examined are the implications for macro-policy of new research, including Joseph Stiglitz's warning on the misplaced zeal for financial market liberalization which partly engendered the East Asian and Russian crises.
Book Synopsis How Well Do Economists Forecast Recessions? by : Zidong An
Download or read book How Well Do Economists Forecast Recessions? written by Zidong An and published by International Monetary Fund. This book was released on 2019-03-05 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: We describe the evolution of forecasts in the run-up to recessions. The GDP forecasts cover 63 countries for the years 1992 to 2014. The main finding is that, while forecasters are generally aware that recession years will be different from other years, they miss the magnitude of the recession by a wide margin until the year is almost over. Forecasts during non-recession years are revised slowly; in recession years, the pace of revision picks up but not sufficiently to avoid large forecast errors. Our second finding is that forecasts of the private sector and the official sector are virtually identical; thus, both are equally good at missing recessions. Strong booms are also missed, providing suggestive evidence for Nordhaus’ (1987) view that behavioral factors—the reluctance to absorb either good or bad news—play a role in the evolution of forecasts.

Book Synopsis Macroeconomic Survey Expectations by : Michael P. Clements
Download or read book Macroeconomic Survey Expectations written by Michael P. Clements and published by Springer. This book was released on 2018-12-31 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why should we be interested in macroeconomic survey expectations? This important book offers an in-depth treatment of this question from a point of view not covered in existing works on time-series econometrics and forecasting. Clements presents the nature of survey data, addresses some of the difficulties posed by the way in which survey expectations are elicited and considers the evaluation of point predictions and probability distributions. He outlines how, from a behavioural perspective, surveys offer insight into how economic agents form their expectations.
Book Synopsis Rigid Body Kinematics and C++ Code by : Sergio Pissanetzky
Download or read book Rigid Body Kinematics and C++ Code written by Sergio Pissanetzky and published by SciControls.com. This book was released on 2005-04 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presented here is an integrated approach - perhaps the first in its class - of advanced Rigid Body Kinematics with the object-oriented C++ code that implements the rigid body objects and brings them to life. Thinking in terms of objects is the natural way of thinking. The concept of object has existed in Science for centuries. More recently, objects were introduced in Computation, and object-oriented programming languages were created. Yet the concept of object is not routinely used when teaching Science, and the idea that objects can come alive in a computer has not yet been fully exploited.This book is Volume 2 of the multi-volume series "Articulated Robot Mechanics and C++ Code". Volume 1 is "Vectors, Matrices and C++ Code", published in 2004. Volumes to be published are "Articulated Robot Dynamics and C++ Code", and "Articulated Robot Control and C++ Code". More volumes may be added in the future.This book integrates advanced rigid body Kinematics with object-oriented concepts and the actual code implementing them. It is both a textbook and a software release, complete with software documentation and the mathematical background that supports the code. The source code is included by download and readers can use it for their own programming. The reader will need a basic knowledge of Physics, particularly Mechanics, and Algebra and Trigonometry. Familiarity with C++ is not required because a course on C++ is included in Volume 1. You should read this book if you are a developer who needs an advanced background in rigid body Kinematics, a student of Physics or Engineering who needs to learn C++, a scientist who needs to write advanced code but can't waste time developing the basics, or you just need ready-to-use C++ source code for your project.
