Available in PDF, EPUB and Kindle. Book excerpt: "Recently, Imbs et. al. (2002) have claimed that much of the purchasing power parity puzzle can be explained by 'aggregation bias'. This paper re-examines aggregation bias. First, it clarifies the meaning of aggregation bias and its applicability to the PPP puzzle. Second, the size of the 'bias' is shown to be much smaller than the simulations in Imbs et. al. (2002) suggest, if we rule out explosive roots in the simulations. Third, we show that the presence of non-persistent measurement error especially in the Imbs et. al. (2002) data can make price series appear less persistent than they really are. Finally, it is now standard to recognize that small-sample bias plagues estimates of speeds of convergence of PPP. After correcting small sample bias by methods proposed by Kilian (1998) and by So and Shin (1999), the half-life estimates indicate that heterogeneity and aggregation bias do not help to solve the PPP puzzle"--NBER website

Book excerpt: "This article summarizes our views on the role of an "aggregation bias" in explaining the PPP (i.e. purchasing power parity) Puzzle, in response to the several papers recently written in reaction to our initial contribution. We discuss in particular the criticisms of Imbs, Mumtaz, Ravn and Rey (2002) presented in Chen and Engel (2005). We show that their contentions are based on: (i) analytical counter-examples which are not empirically relevant; (ii) simulation results minimizing the extent of "aggregation bias"; (iii) unfounded claims on the impact of measurement errors on our results; and (iv) problematic implementation of small-sample bias corrections. We conclude, as in our original paper, that "aggregation bias" goes a long way towards explaining the PPP puzzle"--National Bureau of Economic Research web site.

Book excerpt: We show the importance of a dynamic aggregation bias in accounting for the PPP puzzle. We prove that established time series and panel methods substantially exaggerate the persistence of real exchange rates because of heterogeneity in the dynamics of disaggregated relative prices. When heterogeneity is properly taken into account, estimates of the real exchange rate half-life fall dramatically, to little more than one year, or significantly below Rogoff's consensus view' of three to five years. We show corrected estimates are consistent with plausible nominal rigidities, thus, arguably, solving the puzzle. We also explain why traded goods prices account for the bulk of the persistence and volatility of the real exchange rate. The reason is that traded goods prices display dynamics that are more heterogeneous than non-traded ones.

Download or read book Purchasing Power Parity and Real Exchange Rates written by Mark P. Taylor and published by Routledge. This book was released on 2013-09-13 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term Purchasing Power Parity may date from the early twentieth century, when it was coined by the Swedish economist Gustav Cassel, but the underlying concept had been enjoying varying degrees of success since its development in sixteenth century Spain. Even towards the end of the twentieth century, and especially since the breakdown of the Bretton Woods system of fixed exchange rates, PPP and the stability of real exchange rates continued to be the subject of academic debate. This volume brings together essays covering aspects of current thinking on Purchasing Power Parity, from the various ways in which to test for its existence, to its appearance in different economies around the world, to examinations of the explanations given when PPP does not appear to hold This book was published as a special issue of Applied Financial Economics. The academic editor of this journal is Mark P. Taylor.

Download or read book Exchange Rate Dynamics written by Martin D. D. Evans and published by Princeton University Press. This book was released on 2011-03-14 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive and in-depth look at exchange-rate dynamics Variations in the foreign exchange market influence all aspects of the world economy, and understanding these dynamics is one of the great challenges of international economics. This book provides a new, comprehensive, and in-depth examination of the standard theories and latest research in exchange-rate economics. Covering a vast swath of theoretical and empirical work, the book explores established theories of exchange-rate determination using macroeconomic fundamentals, and presents unique microbased approaches that combine the insights of microstructure models with the macroeconomic forces driving currency trading. Macroeconomic models have long assumed that agents—households, firms, financial institutions, and central banks—all have the same information about the structure of the economy and therefore hold the same expectations and uncertainties regarding foreign currency returns. Microbased models, however, look at how heterogeneous information influences the trading decisions of agents and becomes embedded in exchange rates. Replicating key features of actual currency markets, these microbased models generate a rich array of empirical predictions concerning trading patterns and exchange-rate dynamics that are strongly supported by data. The models also show how changing macroeconomic conditions exert an influence on short-term exchange-rate dynamics via their impact on currency trading. Designed for graduate courses in international macroeconomics, international finance, and finance, and as a go-to reference for researchers in international economics, Exchange-Rate Dynamics guides readers through a range of literature on exchange-rate determination, offering fresh insights for further reading and research. Comprehensive and in-depth examination of the latest research in exchange-rate economics Outlines theoretical and empirical research across the spectrum of modeling approaches Presents new results on the importance of currency trading in exchange-rate determination Provides new perspectives on long-standing puzzles in exchange-rate economics End-of-chapter questions cement key ideas

Download or read book Forecasting and Hedging in the Foreign Exchange Markets written by Christian Ullrich and published by Springer Science & Business Media. This book was released on 2009-05-30 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historical and recent developments at international ?nancial markets show that it is easy to loose money, while it is dif?cult to predict future developments and op- mize decision-making towards maximizing returns and minimizing risk. One of the reasons of our inability to make reliable predictions and to make optimal decisions is the growing complexity of the global economy. This is especially true for the f- eign exchange market (FX market) which is considered as one of the largest and most liquid ?nancial markets. Its grade of ef?ciencyand its complexityis one of the starting points of this volume. From the high complexity of the FX market, Christian Ullrich deduces the - cessity to use tools from machine learning and arti?cial intelligence, e.g., support vector machines, and to combine such methods with sophisticated ?nancial mod- ing techniques. The suitability of this combination of ideas is demonstrated by an empirical study and by simulation. I am pleased to introduce this book to its - dience, hoping that it will provide the reader with interesting ideas to support the understanding of FX markets and to help to improve risk management in dif?cult times. Moreover, I hope that its publication will stimulate further research to contribute to the solution of the many open questions in this area.

Available in PDF, EPUB and Kindle. Book excerpt: What conclusions can be drawn from recent advances in international trade and international macroeconomics? New datasets, theoretical models, and empirical studies have resulted in fresh questions about the world trade and payment system. These chapters--six on trade and six on international macroeconomics--reveal the richness that researchers have uncovered in recent years. The chapters on foreign trade present, among other subjects, new integrated multisector analytical frameworks, the use of gravity equations for the estimation of trade flows, the role of domestic institutions in shaping comparative advantage, and international trade agreements. On international macroeconomics, chapters explore the relation between exchange rates and other macroeconomic variables; risk sharing, allocation of capital across countries, and current account dynamics; and sovereign debt and financial crises. By addressing new issues while enabling deeper and sharper analyses of old issues, this volume makes a significant contribution to our understanding of the global economy. - Systematically illuminates and interprets recent developments in research on international trade and international macroeconomics - Focuses on newly developing questions and opportunities for future research - Presents multiple perspectives on ways to understand the global economy

Download or read book Potential Pitfalls for the Purchasing power parity Puzzle written by Alan M. Taylor and published by . This book was released on 2000 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The PPP puzzle is based on empirical evidence that international price differences for individual goods (LOOP) or baskets of goods (PPP) appear highly persistent or even non-stationary. The present consensus is these price differences have a half-life that is of the order of five years at best, and infinity at worst. This seems unreasonable in a world where transportation and transaction costs appear so low as to encourage arbitrage and the convergence of price gaps over much shorter horizons, typically days or weeks. However, current empirics rely on a particular choice of methodology, involving (i) relatively low-frequency monthly, quarterly, or annual data, and (ii) a linear model specification. In fact, these methodological choices are not innocent, and they can be shown to bias analysis to-wards findings of slow convergence and a random walk. Intuitively, if we suspect that the actual adjustment horizon is of the order of days then monthly and annual data cannot be expected to reveal it. If we suspect arbitrage costs are high enough to produce a substantial band of inaction' then a linear model will fail to support convergence if the process spends considerable time random-walking in that band. Thus, when testing for PPP or LOOP, model specification and data sampling should not proceed without consideration of the actual institutional context and logistical framework of markets.

Available in PDF, EPUB and Kindle. Book excerpt: Praise for Handbook of Exchange Rates “This book is remarkable. I expect it to become the anchor reference for people working in the foreign exchange field.” —Richard K. Lyons, Dean and Professor of Finance, Haas School of Business, University of California Berkeley “It is quite easily the most wide ranging treaty of expertise on the forex market I have ever come across. I will be keeping a copy close to my fingertips.” —Jim O’Neill, Chairman, Goldman Sachs Asset Management How should we evaluate the forecasting power of models? What are appropriate loss functions for major market participants? Is the exchange rate the only means of adjustment? Handbook of Exchange Rates answers these questions and many more, equipping readers with the relevant concepts and policies for working in today’s international economic climate. Featuring contributions written by leading specialists from the global financial arena, this handbook provides a collection of original ideas on foreign exchange (FX) rates in four succinct sections: • Overview introduces the history of the FX market and exchange rate regimes, discussing key instruments in the trading environment as well as macro and micro approaches to FX determination. • Exchange Rate Models and Methods focuses on forecasting exchange rates, featuring methodological contributions on the statistical methods for evaluating forecast performance, parity relationships, fair value models, and flow–based models. • FX Markets and Products outlines active currency management, currency hedging, hedge accounting; high frequency and algorithmic trading in FX; and FX strategy-based products. • FX Markets and Policy explores the current policies in place in global markets and presents a framework for analyzing financial crises. Throughout the book, topics are explored in-depth alongside their founding principles. Each chapter uses real-world examples from the financial industry and concludes with a summary that outlines key points and concepts. Handbook of Exchange Rates is an essential reference for fund managers and investors as well as practitioners and researchers working in finance, banking, business, and econometrics. The book also serves as a valuable supplement for courses on economics, business, and international finance at the upper-undergraduate and graduate levels.

Download or read book The Equity Home Bias Puzzle written by Ian Cooper and published by . This book was released on 2013 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: Home bias - the empirical phenomenon that investors assign anomalously high weights to their own domestic assets - has puzzled academics for decades: financial theory predicts that an internationally well diversified portfolio of stocks and short-term bonds can reduce risk significantly without affecting expected return. Although the globalization of international equity markets has increased international investments, equity portfolios remain severely home biased today, and no single explanation seems to solve the puzzle completely. In this paper, we first provide a thorough description of the equity home bias phenomenon by defining, discussing, and applying the competing measures and presenting some estimates of the costs of under-diversification. Second, we evaluate the explanations for the equity home bias proposed in the literature such as information asymmetries, behavioral aspects, barriers to foreign investment, and governance issues, and conclude that each explanation on its own falls short, suggesting that the equity home bias probably reflects a combination of factors. Lastly, we review the implications of international under-diversification for portfolio formation and the cost of capital of companies.

Download or read book World Development Report 2009 written by World Bank and published by World Bank Publications. This book was released on 2008-11-04 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rising densities of human settlements, migration and transport to reduce distances to market, and specialization and trade facilitated by fewer international divisions are central to economic development. The transformations along these three dimensions density, distance, and division are most noticeable in North America, Western Europe, and Japan, but countries in Asia and Eastern Europe are changing in ways similar in scope and speed. 'World Development Report 2009: Reshaping Economic Geography' concludes that these spatial transformations are essential, and should be encouraged. The conclusion is not without controversy. Slum-dwellers now number a billion, but the rush to cities continues. Globalization is believed to benefit many, but not the billion people living in lagging areas of developing nations. High poverty and mortality persist among the world's 'bottom billion', while others grow wealthier and live longer lives. Concern for these three billion often comes with the prescription that growth must be made spatially balanced. The WDR has a different message: economic growth is seldom balanced, and efforts to spread it out prematurely will jeopardize progress. The Report: documents how production becomes more concentrated spatially as economies grow. proposes economic integration as the principle for promoting successful spatial transformations. revisits the debates on urbanization, territorial development, and regional integration and shows how today's developers can reshape economic geography.
