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 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.

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.

This book was released on 2009-04 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seminar paper from the year 2008 in the subject Business economics - Miscellaneous, grade: A, Schmalkalden University of Applied Sciences (Schmalkalden University), language: English, abstract: "Under the skin of any international economist lies a deep-seated belief in some variant of the PPP theory of the exchange rate." The purpose of this paper is to consider one of the most controversial theory in international economics - Purchasing Power Parity theory - its main idea, empirical evidence, limitations and practical application. The main idea of PPP is price levels changes determine the exchange rate change between two countries. There are two versions of PPP theory absolute and relative. Stricter absolute version of PPP did not find confirmation in reality and relative version of PPP theory was proposed. Despite theoretical and practical inconformity, PPP is present in many models of international economics as an explanation of exchange rate changes. The main apologist of PPP theory and its father was Gustav Cassel. He indicated that the exchange rate determined by price levels is not necessarily the actual exchange rate but the equilibrium one. Also Cassel mentioned that there is a tendency for the actual exchange rate to return to its equilibrium exchange rate. The original idea of PPP theory is described below: "Our willingness to pay a certain price for foreign money must ultimately and essentially be due to the fact that this money possesses a purchasing power as against commodities and services in that foreign country." In this paper we considered the principle and two versions of PPP theory, discussed its empirical evidence and econometrical tests, and also tried to find possible reasons why PPP theory fails in reality and answered the question is this theory still useful for explaining exchange rates movements.

This book was released on 2008-04-15 with total page 744 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inflation became the dominant economic, social, and political problem of the industrialized West during the 1970s. This book is about how the inflation came to pass and what can be done about it. Certain to provoke controversy, it is a major source of new empirical information and theoretical conclusions concerning the causes of international inflation. The authors construct a consistent data base of information for eight countries and design a theoretically sound model to test and evaluate competing hypotheses incorporating the most recent theoretical developments. Additional chapters address an impressive variety of issues that complement and corroborate the core of the study. They answer such questions as these: Can countries conduct an independent monetary policy under fixed exchange rates? How closely tied are product prices across countries? How are disturbances transmitted across countries? The International Transmission of Inflation is an important contribution to international monetary economics in furnishing an invaluable empirical foundation for future investigation and discussion.

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: 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 2019-09-13 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper offers an empirical model of the drivers of the level of the Real Effective Exchange Rate (REER) that is now part of the IMF’s methodology for the assessment of external positions, including exchange rates. It constructs a measure of the level of the REER and it offers a panel regression that considers a large number of cross-sectional and time varying factors, guided by the extensive literature. Its main contribution is to enhance our understanding of the cross-sectional determinants of the level of the REER, while taking into account the time-series drivers. The framework accounts for the much larger cross-sectional variation of the level REER, and can better explain the time series variation of level REER when these are based on GDP-deflators rather than on consumer price indices. The latter suggest there may be merits to broadening the assessments to include such measures, although further analysis is required.

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.
