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.

Book Synopsis 'Aggregation Bias' Does Explain the PPP Puzzle by : Jean Imbs
Download or read book 'Aggregation Bias' Does Explain the PPP Puzzle written by Jean Imbs and published by . This book was released on 2005 with total page 48 pages. Available in PDF, EPUB and Kindle. 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.

Book excerpt: "The real exchange rate (RER) has been called the single most important price, yet its behavior exhibits several puzzles. In this project, we use Big Mac prices as a unique prism to study the movement of real exchange rates. Part of our innovation is to match these prices to the prices of individual ingredients. There are a number of advantages associated with our approach. First, unlike the CPI RER, we can measure the Big Mac RER in levels. Second, unlike the CPI RER, for which the attribution to tradable and non-tradable components involves assumptions on the weights and the functional form, we (almost) know the exact composition of a Big Mac, and can estimate the tradable and non-tradable components relatively precisely. Third, we can study the dynamics of the RER in a setting free of: the product-aggregation bias, the temporal aggregation bias, and the bias generated by non-compatible consumption baskets across countries. Fourth that Engel's result that deviations from the law of one price are sole explanation for RER movements does not hold generally. We offer some evidence that departure from the Engel effect can be systematically linked to economic factors"--NBER website

Book Synopsis Does "aggregation Bias" Explain the PPP Puzzle? by : Shiu-Sheng Chen
Download or read book Does "aggregation Bias" Explain the PPP Puzzle? written by Shiu-Sheng Chen and published by . This book was released on 2004 with total page 54 pages. 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
Book Synopsis Purchasing Power Parity and Real Exchange Rates by : Mark P. Taylor
Download or read book Purchasing Power Parity and Real Exchange Rates written by Mark P. Taylor and published by Routledge. This book was released on 2013-09-13 with total page 227 pages. 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.

Book Synopsis Understanding the PPP Puzzle by : Shifu Jiang
Download or read book Understanding the PPP Puzzle written by Shifu Jiang and published by . This book was released on 2017 with total page 28 pages. Available in PDF, EPUB and Kindle. 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 Synopsis The Level REER model in the External Balance Assessment (EBA) Methodology by : Rui Mano
Download or read book The Level REER model in the External Balance Assessment (EBA) Methodology written by Rui Mano and published by International Monetary Fund. 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.

This book was released on 2019-03-19 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assessment of external positions and exchange rates is a key mandate of the IMF. This paper presents the updated External Balance Assessment (EBA) framework—a key input in the conduct of multilaterally-consistent external sector assessments of 49 advanced and emerging market economies—following the two rounds of refinements adopted since the framework was introduced in 2012 (as described in Phillips et al., 2013). It also presents new complementary tools for shedding light on the role of structural factors in explaining external imbalances and assessing potential biases in the measurement of external positions. Remaining challenges and areas of future work are also discussed.
Download or read book Capitalism written by Anwar Shaikh and published by Oxford University Press. This book was released on 2016-01-15 with total page 1019 pages. Available in PDF, EPUB and Kindle. Book excerpt: Orthodox economics operates within a hypothesized world of perfect competition in which perfect consumers and firms act to bring about supposedly optimal outcomes. The discrepancies between this model and the reality it claims to address are then attributed to particular imperfections in reality itself. Most heterodox economists seize on this fact and insist that the world is characterized by imperfect competition. But this only ties them to the notion of perfect competition, which remains as their point of departure and base of comparison. There is no imperfection without perfection. In Capitalism, Anwar Shaikh takes a different approach. He demonstrates that most of the central propositions of economic analysis can be derived without any reference to standard devices such as hyperrationality, optimization, perfect competition, perfect information, representative agents, or so-called rational expectations. This perspective allows him to look afresh at virtually all the elements of economic analysis: the laws of demand and supply, the determination of wage and profit rates, technological change, relative prices, interest rates, bond and equity prices, exchange rates, terms and balance of trade, growth, unemployment, inflation, and long booms culminating in recurrent general crises. In every case, Shaikh's innovative theory is applied to modern empirical patterns and contrasted with neoclassical, Keynesian, and Post-Keynesian approaches to the same issues. Shaikh's object of analysis is the economics of capitalism, and he explores the subject in this expansive light. This is how the classical economists, as well as Keynes and Kalecki, approached the issue. Anyone interested in capitalism and economics in general can gain a wealth of knowledge from this ground-breaking text.
