Book Description
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.

Book Description
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.

Book Description
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.

Book Description
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 Description
"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

Book Description
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.
