Failures of the law of one price explain much of the variation in real C.P.I. exchange rates. We use C.P.I. data for U.S. cities and Canadian cities for 14 categories of consumer prices to examine the nature of the deviations from the law of one price. The distance between cities explains a...

The purchasing power parity puzzle relates to the adjustment of real exchange rates. Real exchange rates are extremely volatile, suggesting that temporary shocks emanate from the monetary sector. But the half-life of real exchange rate deviations is extremely large -- 2.5 to 5 years. This...

This paper builds a model of adjustment toward PPP for a panel of real exchange rates. The model eliminates some inconsistencies in previous models, which implied a model for the real exchange rate of country B relative to country C that was not commensurate with the posited model of the real...

We investigate the behavior of the long-run U.S./U.K. real exchange rate from 1885 to 1995. Our long-run real exchange rate series is derived from an unobserved components model which divides the real exchange rate into permanent and transitory components. The transitory component is modeled as...

We apply the method of constrained asset share estimation (CASE) to test the mean-variance efficiency (MVE) of the stock market. This method allows conditional expected returns to vary in relatively unrestricted ways. The data estimate reasonably the price of risk, and, in some cases, the MVE...

This paper uncovers a striking empirical regularity: the consumer price of a good relative to a different good within a country tends to be much less variable than the price of that good relative to a similar good in another country. This fact seems to hold for all goods except very simple,...

A Markov-switching model is fit for eighteen exchange rates at quarterly and monthly frequencies. This model fits well in-sample at the quarterly frequency for many exchange rates. By the mean-squared-error or mean-absolute-error criterion. the Markov model does not generate superior forecasts...

This study quantitatively investigates the currency composition of sovereign debt in the presence of two types of limited enforcement frictions arising from a government's monetary and debt policy: strategic currency debasement and default on sovereign debt. Local currency debt obligations are...

We investigate the link between real exchange rates and sectoral total factor productivity measures for countries in the Eurozone. Real exchange rate patterns closely accord with an amended Balassa-Samuelson interpretation, both in cross-section and time series. We construct a sticky price...

This paper surveys recent theoretical and empirical contributions on foreign exchange rate determination. The paper first considers monetary models under uncovered interest parity and rational expectations. Then the paper considers deviations from UIP/rational expectations: foreign exchange risk...
