Book Description
This paper examines the evidence for two of the relationships that underpin (explicitly or implicitly) much of international macroeconomics. The first is purchasing power parity (PPP), or the hypothesis that there exists a constant long-run equilibrium real exchange rate. The second establishes a relationship between real exchange rates and real interest rate differentials. The tests are conducted on a panel of 18 OECD economies using the United States as a numeraire for the post-Bretton Woods era. The results are obtained using new non-stationary panel estimation techniques, which significantly increase the power of the tests. All the tests suggest that there is little evidence supporting PPP when it is tested directly. This contrasts with earlier panel data studies, which tended to find that the real exchange rate was stationary. The results supporting a long-run relationship between real exchange rates and real interest rate differentials appear to be more positive. This again provides a contrast with earlier results, which tended to find no evidence of cointegration. Such studies concentrated on G7 economies. To investigate this further the panel was split into two groups: the G7 and eleven small open economies. For the panel of small open economies strong evidence in favour of cointegration is found. In contrast, there is no evidence of cointegration in a panel that consists purely of the G7 economies.

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
Combining thorough scholarship with illuminating real-world examples, this edited collection provides insights on the causes and consequences of movements in both exchange rates and external assets and has a strong focus on the policy implications of operating in an open economy, particularly the choice of exchange rate and monetary policy, exchange rate intervention and policies on capital mobility.

Book Description
"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 Description
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 Description
The paper finds significant deviations between short-term emerging market real interest rates and world real interest rates primarily due to the inflationary expectations of the local investor base. We test for long-run real interest convergence in emerging markets using a time varying panel unit root test proposed by Pesaran to capture the improved macro-economic fundamentals since early 1990s. We also estimate the speed of convergence in the presence of a shock. The paper suggests that real interest rates in the emerging markets show some convergence in the long run but real interest parity does not hold. Our results also find that the speed of adjustment of real rates to a shock is estimated to differ significantly across the emerging markets. Measured by their half-life, some emerging markets in Asia, E.Europe and S.Africa, where real interest rates are generally low, take much longer to adjust than where real interest rates are generally high (Latin America, Turkey). From a policy perspective, encouraging foreign investors to take direct exposure at the short end of the local debt market could lower the real interest rates in some emerging markets.

Book Description
"The authors argue that the cross-market premium (the ratio between the domestic and the international market price of cross-listed stocks) provides a valuable measure of international financial integration, reflecting accurately the factors that segment markets and inhibit price arbitrage. Applying to equity markets recent methodological developments in the purchasing power parity literature, they show that nonlinear Threshold Autoregressive (TAR) models properly capture the behavior of the cross market premium. The estimates reveal the presence of narrow non-arbitrage bands and indicate that price differences outside these bands are rapidly arbitraged away, much faster than what has been documented for good markets. Moreover, the authors find that financial integration increases with market liquidity. Capital controls, when binding, contribute to segment financial markets by widening the non-arbitrage bands and making price disparities more persistent. Crisis episodes are associated with higher volatility, rather than by more persistent deviations from the law of one price. "--World Bank web site.
