Book excerpt: We model the real exchange rates between the US and 18 OECD countries by an innovative dynamic process called integral correction mechanism, and allow a real exchange rate equilibrium determined by Harrod-Balassa-Samuelson effects. The Harrod-Balassa-Samuelson effect works through a direct channel and a terms of trade channel. We find that the terms of trade channel is significant in more countries than the direct channel. Using a popular smooth transition autoregression model as a benchmark, we find that our model often statistically outperforms the benchmark. And the origin of this superiority is that our model captures autocorrelation functions of the real exchange rates very well. Our model features that the real exchange rate reverts to its equilibrium very quickly in the short run but moves back and forth around the equilibrium in the long run. These particular dynamics help us understand Rogoff's PPP puzzle and forecast the real exchange rate.

Book excerpt: This article shows that global financial markets cannot, by themselves, achieve net transfers of financial capital and real interest rate equalisation across countries and that the integration of both global financial markets and global goods markets is needed to achieve net transfers of capital and real interest rate equalisation across countries. Thus, frictions (barriers to mobility) in one or both of these markets can impede the net transfer of capital between countries, produce the Feldstein and Horioka (1980) finding of high saving-investment correlations, and prevent real interest rates from being equalised across countries. Moreover, frictions in global goods markets can explain why real exchange rates deviate from PPP (purchasing power parity) for extended periods of time and can therefore also explain the PPP puzzle. Thus, we are able to resolve 2 of Obstfeld and Rogoff's (2000) "6 major puzzles in macroeconomics" with essentially the same explanation.

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: “A brilliant and lucid new book” (John Lanchester, New York Times Magazine) about why paper money and digital currencies lie at the heart of many of the world’s most difficult problems—and their solutions In The Curse of Cash, acclaimed economist and bestselling author Kenneth Rogoff explores the past, present, and future of currency, showing why, contrary to conventional economic wisdom, the regulation of paper bills—and now digital currencies—lies at the heart some of the world’s most difficult problems, but also their potential solutions. When it comes to currency, history shows that the private sector often innovates but eventually the government regulates and appropriates. Using examples ranging from the history of standardized coinage to the development of paper money, Rogoff explains why the cryptocurrency boom will inevitably end with dominant digital currencies created and controlled by governments, regardless of what Bitcoin libertarians want. Advanced countries still urgently need to stem the global flood of large paper bills—the vast majority of which serve no legitimate purpose and only enable tax evasion and other crimes—but cryptocurrencies are like $100 bills on steroids. The Curse of Cash is filled with revealing insights about many of the most pressing issues facing monetary policymakers, from quantitative easing to alternative inflation targeting regimes. It also explains in detail why, if low interest rates persist, the best way to reinvigorate monetary policy is to implement fully effective and unconstrained negative interest rates. Provocative, engaging, and backed by compelling original arguments and evidence, The Curse of Cash has sparked widespread debate and its ideas have moved to the center of financial and policy discussions.

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.

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: "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
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.

Book excerpt: This paper approaches the PPP puzzle by using the Bitcoin/US Dollar exchange rate. The use of the virtual currency as macroeconomic laboratory allows us to remove frictions that previously impeded the empirical demonstration of the law of one price. We show that price adjustments are still far from perfect due to information asymmetry between agents. Nevertheless, the real exchange rate is stationary and adjusts by 81% within one day. Finally, because of the different speed of information spread, good market arbitrage takes place in the Bitcoin economy but not in the US economy. Thus, we conclude that in a frictionless economy the PPP holds and the speed of arbitrage for the good market depends on the speed of information spread among agents.
