Book excerpt: Recent tests using long data series find evidence in favor of long-run PPP (by rejecting either the null hypothesis of unit roots in real exchange rates or the null of no cointegration between nominal exchange rates and relative prices.) These tests may have reached the wrong conclusion. Monte Carlo experiments using artificial data calibrated to nominal exchange rates and disaggregated data on prices show that tests of long-run PPP have serious size biases. They may fail to detect a sizable and economically significant unit root component. For example, in the baseline case which is calibrated to actual price data, unit roots and cointegration tests with a nominal size of five percent have true sizes that range from .90 to .98 in artificial 100-year long data series, even though the unit root component accounts for 42% of the variance of the real exchange rate in sample. On the other hand, tests of stationarity are shown to have very low power in the same circumstances, so it is quite likely that a researcher would reject a unit root and fail to reject stationarity even when the series embodied a large unit root component.

Book excerpt: Recent tests using long data series find evidence in favor of long-run PPP. These tests may have reached the wrong conclusion. Using artificial data calibrated to nominal exchange rates and disaggregated data on prices, we show that tests on long-run PPP have serious size biases. In the baseline case, unit root and cointegration tests with a nominal size of five per cent have true sizes that range from 0.90 to 0.99 in 100-year long data series, even though there is a permanent component that accounts for 42% of the 100-year forecast variance of the real exchange rate. Tests of stationarity are shown to have very low power in the same circumstances.

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.

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 Pass through of Exchange Rates and Purchasing Power Parity written by Robert C. Feenstra and published by . This book was released on 1994 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper we develop and test two hypotheses about purchasing power parity (PPP) derived from the pricing behavior of profit- maximizing, exporting firms. The first is that changes in the price of traded goods relative to domestic substitutes, due to partial pass- through of exchange rates, will affect the PPP relation. The second is that PPP should hold on forward rather than spot exchange rates, due to hedging by firms. Using quarterly data for the United States, Canada, France, Germany, Japan and the United Kingdom, we find considerable support for the first but not the second hypothesis.

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

Download or read book Long Run Exchange Rate Dynamics written by Mr.Karl Friedrich Habermeier and published by International Monetary Fund. This book was released on 1999-04-01 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long-run movements of real exchange rates are studied using a panel data set comprising 51 economies. The purchasing power parity hypothesis (PPP) is examined first using unit root tests. It is found that PPP does not hold for the full sample of countries, but it may hold for the advanced economies, as well as open and high-inflation economies. Using the recently developed mean group and pooled mean group estimators, the paper finds support for the Balassa-Samuelson hypothesis in both advanced and developing economies; and for the influence of shifts in the terms of trade.

Download or read book Does the Long Run Ppp Hypothesis Hold for Africa Evidence From Panel Co Integration Study written by Jun Nagayasu and published by International Monetary Fund. This book was released on 1998-08 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study tests for the consistency of the long-run purchasing power parity (PPP) hypothesis with the observed behavior of parallel market exchange rates for 16 African countries, using the panel co-integration method developed by Pedroni (1995). To test for long-run PPP is important for a number of reasons: many monetary models, a la Dornbusch (1976), hinge on the validity of long-run PPP theory, while many other macroeconomic models often use PPP to link domestic and foreign developments. Furthermore, although the PPP hypothesis may not be regarded as an explicit exchange rate theory, it may still serve to provide fundamental determinants that can be used to calculate the long-run exchange rates and assess the appropriate level of exchange rates when a long-run relationship exists."

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.

Available in PDF, EPUB and Kindle. Book excerpt: This book collects together the basic documents of an approach to the theory and policy of the balance of payments developed in the 1970s. The approach marked a return to the historical traditions of international monetary theory after some thirty years of departure from them – a departure occasioned by the international collapse of the 1930s, the Keynesian Revolution and a long period of war and post-war reconstruction in which the international monetary system was fragmented by exchange controls, currency inconvertibility and controls over international trade and capital movements.
Download or read book A Panel Unit Root Test Approach to PPP Exchange Rates with Non linear Deterministic Trends written by and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper investigates the purchasing power parity (PPP) hypothesis using panel data. Under PPP the real exchange rate is stationary around a constant mean. Recent panel data unit root tests are employed to test the PPP proposition where, under the conventional null hypothesis of a unit root, the real exchange rate is not stationary and PPP does not hold. In this case, as the time period t + n approaches infinity, its variance relative to period t will also approach infinity. The usual alternative in unit root tests is stationarity around a constant mean or a linear trend. The paper brings innovation into the PPP and panel unit root testing literature by allowing for possible nonlinear deterministic trends in the alternative hypothesis (as advanced by Cushman (2004)). If the null hypothesis is rejected in favour of the alternative of a non-linear trend, PPP still does not hold, but does at least revert back to a meaningful, stable long-run equilibrium. Given this non-linear trend, the variance of the real exchange rate as t + n approaches infinity, conditional on that trend, remains finite. Overall, evidence for stationarity in exchange rates is found in four out of six panels under consideration, including both support for stationary processes with no trend or a linear trend as well as for processes following a non-linear deterministic trend, in particular at time orders 5 and 6. The rejections are, in fact, most consistent at the nonlinear orders. Given nonlinear trends, PPP as usually defined does not hold, despite the rejection of unit roots. It is also found that stronger evidence for stable long-run equilibria in real exchange rates appears when the German Deutschmark is chosen as a base currency instead of the US Dollar. Finally, it appears that a very recent panel unit root test that takes account of cross-sectional dependencies delivers more consistent and sensible results.
