This book was released on 2022 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents evidence for sources and channels of nonlinearities and instabilities of the new Keynesian Phillips curve (NKPC) for the euro area and all but four member states over the last two decades prior to the COVID-19 crisis. The approach rests upon misspecification testing using auxiliary regressions based on the standard open-economy hybrid NKPC. Using a large number of specifications, this approach allows to systematically, i. e., based on a literature review, disentangle the evidence for nonlinearities and instabilities of the NKPC according to sources and channels. For the euro area and most considered member states, there is substantial evidence for nonlinearities and instabilities. The relatively most important channels of nonlinearities and instabilities are similar across countries, whereas the relatively most important sources differ across countries. The results strongly indicate the need for considering nonlinear NKPC relationships in empirical analyses and also point towards potentially useful nonlinear specifications.

Download or read book Monetary Policy Strategy written by Frederic S. Mishkin and published by MIT Press. This book was released on 2007 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book by a leading authority on monetary policy offers a unique view of the subject from the perspectives of both scholar and practitioner. Frederic Mishkin is not only an academic expert in the field but also a high-level policymaker. He is especially well positioned to discuss the changes in the conduct of monetary policy in recent years, in particular the turn to inflation targeting. Monetary Policy Strategydescribes his work over the last ten years, offering published papers, new introductory material, and a summing up, "Everything You Wanted to Know about Monetary Policy Strategy, But Were Afraid to Ask," which reflects on what we have learned about monetary policy over the last thirty years. Mishkin blends theory, econometric evidence, and extensive case studies of monetary policy in advanced and emerging market and transition economies. Throughout, his focus is on these key areas: the importance of price stability and a nominal anch fiscal and financial preconditions for achieving price stability; central bank independence as an additional precondition; central bank accountability; the rationale for inflation targeting; the optimal inflation target; central bank transparency and communication; and the role of asset prices in monetary policy.

Download or read book A Phillips Curve with Anchored Expectations and Short Term Unemployment written by Laurence M. Ball and published by International Monetary Fund. This book was released on 2015-02-25 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper examines the recent behavior of core inflation in the United States. We specify a simple Phillips curve based on the assumptions that inflation expectations are fully anchored at the Federal Reserve’s target, and that labor-market slack is captured by the level of shortterm unemployment. This equation explains inflation behavior since 2000, including the failure of high total unemployment since 2008 to reduce inflation greatly. The fit of our equation is especially good when we measure core inflation with the Cleveland Fed’s series on weighted median inflation. We also propose a more general Phillips curve in which core inflation depends on short-term unemployment and on expected inflation as measured by the Survey of Professional Forecasters. This specification fits U.S. inflation since 1985, including both the anchored-expectations period of the 2000s and the preceding period when expectations were determined by past levels of inflation.

Download or read book The Inflation Targeting Debate written by Ben S. Bernanke and published by University of Chicago Press. This book was released on 2007-11-01 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past fifteen years, a significant number of industrialized and middle-income countries have adopted inflation targeting as a framework for monetary policymaking. As the name suggests, in such inflation-targeting regimes, the central bank is responsible for achieving a publicly announced target for the inflation rate. While the objective of controlling inflation enjoys wide support among both academic experts and policymakers, and while the countries that have followed this model have generally experienced good macroeconomic outcomes, many important questions about inflation targeting remain. In Inflation Targeting, a distinguished group of contributors explores the many underexamined dimensions of inflation targeting—its potential, its successes, and its limitations—from both a theoretical and an empirical standpoint, and for both developed and emerging economies. The volume opens with a discussion of the optimal formulation of inflation-targeting policy and continues with a debate about the desirability of such a model for the United States. The concluding chapters discuss the special problems of inflation targeting in emerging markets, including the Czech Republic, Poland, and Hungary.

Download or read book River Dynamics written by Bruce L. Rhoads and published by Cambridge University Press. This book was released on 2020-04-29 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rivers are important agents of change that shape the Earth's surface and evolve through time in response to fluctuations in climate and other environmental conditions. They are fundamental in landscape development, and essential for water supply, irrigation, and transportation. This book provides a comprehensive overview of the geomorphological processes that shape rivers and that produce change in the form of rivers. It explores how the dynamics of rivers are being affected by anthropogenic change, including climate change, dam construction, and modification of rivers for flood control and land drainage. It discusses how concern about environmental degradation of rivers has led to the emergence of management strategies to restore and naturalize these systems, and how river management techniques work best when coordinated with the natural dynamics of rivers. This textbook provides an excellent resource for students, researchers, and professionals in fluvial geomorphology, hydrology, river science, and environmental policy.

Download or read book Inflation in Emerging and Developing Economies written by Jongrim Ha and published by World Bank Publications. This book was released on 2019-02-24 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first comprehensive study in the context of EMDEs that covers, in one consistent framework, the evolution and global and domestic drivers of inflation, the role of expectations, exchange rate pass-through and policy implications. In addition, the report analyzes inflation and monetary policy related challenges in LICs. The report documents three major findings: In First, EMDE disinflation over the past four decades was to a significant degree a result of favorable external developments, pointing to the risk of rising EMDE inflation if global inflation were to increase. In particular, the decline in EMDE inflation has been supported by broad-based global disinflation amid rapid international trade and financial integration and the disruption caused by the global financial crisis. While domestic factors continue to be the main drivers of short-term movements in EMDE inflation, the role of global factors has risen by one-half between the 1970s and the 2000s. On average, global shocks, especially oil price swings and global demand shocks have accounted for more than one-quarter of domestic inflation variatio--and more in countries with stronger global linkages and greater reliance on commodity imports. In LICs, global food and energy price shocks accounted for another 12 percent of core inflation variatio--half more than in advanced economies and one-fifth more than in non-LIC EMDEs. Second, inflation expectations continue to be less well-anchored in EMDEs than in advanced economies, although a move to inflation targeting and better fiscal frameworks has helped strengthen monetary policy credibility. Lower monetary policy credibility and exchange rate flexibility have also been associated with higher pass-through of exchange rate shocks into domestic inflation in the event of global shocks, which have accounted for half of EMDE exchange rate variation. Third, in part because of poorly anchored inflation expectations, the transmission of global commodity price shocks to domestic LIC inflation (combined with unintended consequences of other government policies) can have material implications for poverty: the global food price spikes in 2010-11 tipped roughly 8 million people into poverty.

Download or read book Understanding Acoustics written by Steven L. Garrett and published by Springer. This book was released on 2017-02-24 with total page 913 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook provides a unified approach to acoustics and vibration suitable for use in advanced undergraduate and first-year graduate courses on vibration and fluids. The book includes thorough treatment of vibration of harmonic oscillators, coupled oscillators, isotropic elasticity, and waves in solids including the use of resonance techniques for determination of elastic moduli. Drawing on 35 years of experience teaching introductory graduate acoustics at the Naval Postgraduate School and Penn State, the author presents a hydrodynamic approach to the acoustics of sound in fluids that provides a uniform methodology for analysis of lumped-element systems and wave propagation that can incorporate attenuation mechanisms and complex media. This view provides a consistent and reliable approach that can be extended with confidence to more complex fluids and future applications. Understanding Acoustics opens with a mathematical introduction that includes graphing and statistical uncertainty, followed by five chapters on vibration and elastic waves that provide important results and highlight modern applications while introducing analytical techniques that are revisited in the study of waves in fluids covered in Part II. A unified approach to waves in fluids (i.e., liquids and gases) is based on a mastery of the hydrodynamic equations. Part III demonstrates extensions of this view to nonlinear acoustics. Engaging and practical, this book is a must-read for graduate students in acoustics and vibration as well as active researchers interested in a novel approach to the material.

Download or read book Estimating How the Macroeconomy Works written by Ray C. FAIR and published by Harvard University Press. This book was released on 2009-06-30 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macroeconomics tries to describe and explain the economywide movement of prices, output, and unemployment. The field has been sharply divided among various schools, including Keynesian, monetarist, new classical, and others. It has also been split between theorists and empiricists. Ray Fair is a resolute empiricist, developing and refining methods for testing theories and models. The field cannot advance without the discipline of testing how well the models approximate the data. Using a multicountry econometric model, he examines several important questions, including what causes inflation, how monetary authorities behave and what are their stabilization limits, how large is the wealth effect on aggregate consumption, whether European monetary policy has been too restrictive, and how large are the stabilization costs to Europe of adopting the euro. He finds, among other things, little evidence for the rational expectations hypothesis and for the so-called non-accelerating inflation rate of unemployment (NAIRU) hypothesis. He also shows that the U.S. economy in the last half of the 1990s was not a new age economy.

Download or read book Recent Econometric Techniques for Macroeconomic and Financial Data written by Gilles Dufrénot and published by Springer Nature. This book was released on 2020-11-21 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides a comprehensive overview of the latest econometric methods for studying the dynamics of macroeconomic and financial time series. It examines alternative methodological approaches and concepts, including quantile spectra and co-spectra, and explores topics such as non-linear and non-stationary behavior, stochastic volatility models, and the econometrics of commodity markets and globalization. Furthermore, it demonstrates the application of recent techniques in various fields: in the frequency domain, in the analysis of persistent dynamics, in the estimation of state space models and new classes of volatility models. The book is divided into two parts: The first part applies econometrics to the field of macroeconomics, discussing trend/cycle decomposition, growth analysis, monetary policy and international trade. The second part applies econometrics to a wide range of topics in financial economics, including price dynamics in equity, commodity and foreign exchange markets and portfolio analysis. The book is essential reading for scholars, students, and practitioners in government and financial institutions interested in applying recent econometric time series methods to financial and economic data.

Download or read book Inflation Unemployment and Monetary Policy written by Robert M. Solow and published by MIT Press. This book was released on 1998 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Edited and with an introduction by Benjamin M. Friedman The connection between price inflation and real economic activity has been a focus of macroeconomic research--and debate--for much of the past century. Although this connection is crucial to our understanding of what monetary policy can and cannot accomplish, opinions about its basic properties have swung widely over the years. Today, virtually everyone studying monetary policy acknowledges that, contrary to what many modern macroeconomic models suggest, central bank actions often affect both inflation and measures of real economic activity, such as output, unemployment, and incomes. But the nature and magnitude of these effects are not yet understood. In this volume, Robert M. Solow and John B. Taylor present their views on the dilemmas facing U.S. monetary policymakers. The discussants are Benjamin M. Friedman, James K. Galbraith, N. Gregory Mankiw, and William Poole. The aim of this lively exchange of views is to make both an intellectual contribution to macroeconmics and a practical contribution to the solution of a public policy question of central importance.

This book was released on 2006-06-15 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last few years, there has been a convergence between the fields of ultrafast science, nonlinear optics, optical frequency metrology, and precision laser spectroscopy. These fields have been developing largely independently since the birth of the laser, reaching remarkable levels of performance. On the ultrafast frontier, pulses of only a few cycles long have been produced, while in optical spectroscopy, the precision and resolution have reached one part in Although these two achievements appear to be completely disconnected, advances in nonlinear optics provided the essential link between them. The resulting convergence has enabled unprecedented advances in the control of the electric field of the pulses produced by femtosecond mode-locked lasers. The corresponding spectrum consists of a comb of sharp spectral lines with well-defined frequencies. These new techniques and capabilities are generally known as “femtosecond comb technology. ” They have had dramatic impact on the diverse fields of precision measurement and extreme nonlinear optical physics. The historical background for these developments is provided in the Foreword by two of the pioneers of laser spectroscopy, John Hall and Theodor Hänsch. Indeed the developments described in this book were foreshadowed by Hänsch’s early work in the 1970s when he used picosecond pulses to demonstrate the connection between the time and frequency domains in laser spectroscopy. This work complemented the advances in precision laser stabilization developed by Hall.

This book was released on 2001 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A Prescription for Monetary Policy," originally published in 1976, contains the proceedings from a series of seminars. The seminars addressed the question, "How should the Federal Open Market Committee (FOMC) make monetary policy?" The need to carefully reexamine this question gained in urgency as the economic distress story of the mid-1970s unfolded. In recognition of the unsatisfactory state of the economy, a major Federal Reserve System research program was launched under the auspices of the FOMC?s Committee on the Directive. The study?s objective was to produce for the FOMC?s consideration a set of recommendations on how to improve the execution of monetary stabilization policy.

Download or read book Cost Benefit Analysis of Leaning Against the Wind written by Mr.Lars E. O. Svensson and published by International Monetary Fund. This book was released on 2016-01-11 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Leaning against the wind” (LAW) with a higher monetary policy interest rate may have benefits in terms of lower real debt growth and associated lower probability of a financial crisis but has costs in terms of higher unemployment and lower inflation, importantly including a higher cost of a crisis when the economy is weaker. For existing empirical estimates, costs exceed benefits by a substantial margin, even if monetary policy is nonneutral and permanently affects real debt. Somewhat surprisingly, less effective macroprudential policy and generally a credit boom, with resulting higher probability, severity, or duration of a crisis, increases costs of LAW more than benefits, thus further strengthening the strong case against LAW.
