Available in PDF, EPUB and Kindle. Book excerpt: Asset prices undergo long swings that revolve around benchmark levels. In currency markets, fluctuations involve real exchange rates that are highly persistent and that move in near-parallel fashion with nominal rates. The inability to explain these two regularities with one model has been called the quot;Purchasing Power Parity puzzlequot;. In this paper, we trace the puzzle to exchange rate modelers' use of the quot;Rational Expectations Hypothesisquot;. We show that once imperfect knowledge is recognized, a monetary model is able to account for the puzzle, as well as other salient features of the data, including the long-swings behavior of exchange rates.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In a recent paper, Chowdhry, Roll and Xia (2005) make an argument about testing relative purchasing power parity (PPP). They observe that the empirical failure of relative PPP may be because official inflation data are quot;too sticky''. Thus, after extracting unobservable pure price inflation from equity markets, they find strong evidence supporting relative PPP in the short run. This paper further investigates long-run relative PPP using the pure price inflation data constructed by Chowdhry, Roll and Xia (2005). I examine the time series properties of the pure real exchange rate, and fail to reject the null hypothesis that the pure real exchange rate is not mean reverting. Thus, it may be too early to suggest a resolution of the PPP puzzle.

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: The purpose of this paper is to apply a symmetric band threshold autoregressive model to investigate the non-linear adjustment of the real pound-dollar rate over a period from 1885 to 2003. After controlling for the Harrod-Balassa-Samuelson effects, we find evidence to support a non-linear mean reversion of the real pound-dollar rate. Moreover, the estimated half-life is about two years with large shocks. We therefore provide a solution to the purchasing power parity puzzle.

Available in PDF, EPUB and Kindle. Book excerpt: This paper investigates the Purchasing Power Parity Puzzle in the context of a Vector Autoregressive(VAR) model, where the real exchange rate is Granger caused by macroeconomic variables, suggested by 'sticky-price' theories of exchange rate determination. By doing this, we are able to discern the relative effect of nominal price rigidities on the speed of adjustment of the real exchange rate towards long-run PPP. We first show that the impulse response function of a variable participating in the VAR is not, in general, the same with the impulse response function obtained from the equivalent ARMA representation of this variable, if the latter is Granger caused by other variables in the system. The difference between the two functions captures the effects of the Granger-causing variables on the dynamic adjustment process of the variable of interest. Our empirical results for a set of four currencies suggest that price stickiness accounts for 22% to 50% of the half-life of innovations in the real exchange rate.

Book excerpt: "Originally propounded by the sixteenth-century scholars of the University of Salamanca, the concept of purchasing power parity (PPP) was revived in the interwar period in the context of the debate concerning the appropriate level at which to re-establish international exchange rate parities. Broadly accepted as a long-run equilibrium condition in the post-war period, it was first advocated as a short-run equilibrium by many international economists in the first few years following the breakdown of the Bretton Woods system in the early 1970s and then increasingly came under attack on both theoretical and empirical grounds from the late 1970s to the mid 1990s. Accordingly, over the last three decades, a large literature has built up that examines how much the data deviated from theory, and the fruits of this research have provided a deeper understanding of how well PPP applies in both the short run and the long run. Since the mid 1990s, larger datasets and nonlinear econometric methods, in particular, have improved estimation. As deviations narrowed between real exchange rates and PPP, so did the gap narrow between theory and data, and some degree of confidence in long-run PPP began to emerge again. In this respect, the idea of long-run PPP now enjoys perhaps its strongest support in more than thirty years, a distinct reversion in economic thought"--NBER website

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

Available in PDF, EPUB and Kindle. Book excerpt: The international macroeconomics area has experienced substantial growth over the past decade. The goal of this volume is to present the most important developments in the international macroeconomics field in recent years. The literature in this area has evolved mainly in four directions that constitute the four parts of this book. In particular, Part I focuses on the purchasing power parity (PPP) puzzle, Part II presents papers that try to explain the behaviour of nominal and real exchange rates, Part III covers the financial crises, currency crises and contagion recent literature and, finally, the behaviour of exchange rates, inflation and output convergence in Central and Eastern European transition economies are considered in Part IV.

Available in PDF, EPUB and Kindle. Book excerpt: In this paper we analyse the purchasing power parity (PPP) persistence puzzle using a unique data set of black market real exchange rates for 36 emerging market economies and (exact and approximate) median unbiased univariate and panel estimation methods. We construct bootstrap confidence intervals for the half-lives, as well as exact quantiles of the median function for different significance levels using Monte Carlo simulation. Even after accounting for a number of econometric issues, the PPP persistence puzzle is still a striking characteristic of the majority of emerging market countries. However, in a minority of exchange rates, the PPP puzzle is removed.

This book was released on 2008-09-08 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exchange rate analysis lies at the center of the IMF's surveillance mandate and policy advice, as well as in the design of IMF-supported programs, and IMF staff are called upon to analyze a wide variety of exchange rate issues in various member countries, both small and large, from the least economically developed to the most advanced, and from those whose currencies circulate only locally to those whose currencies are of global importance. Each year, IMF staff produce dozens of studies on exchange rate issues, some published by the IMF, others in various professional journals or books. This book aims to give a flavor of the topics the IMF staff typically examine under the broad rubric of exchange rate analysis, encompassing several topics: determination and impact of the real exchange rate, assessing competitiveness and the equilibrium real exchange rate in specific countries or country groups, and considerations in the choice of exchange rate regime.

Available in PDF, EPUB and Kindle. 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 that corrected estimates are consistent with plausible nominal rigidities, thus, arguably, solving the PPP puzzle.
