Why is the forward exchange rate forecast biased? A survey of recent evidence
Forward exchange rate unbiasedness is rejected in tests from the current floating exchange rate era. This paper surveys advances in this area since the publication of Hodrick's (1987) survey. It documents that the change in the future exchange rate is generally negatively related to the forward premium. Properties of the expected forward forecast error are reviewed. Issues such as the relation of uncovered interest parity to real interest parity, and the implications of uncovered interest parity for cointegration of various quantities are discussed. The modeling and testing for risk premiums ...

Deviations from purchasing power parity: causes and welfare costs
We explore deviations from short-run purchasing power parity across European cities, attempting to move beyond a "first-generation" of papers that document very large border effects. We document two very distinct types of border effects embedded in relative prices. The first is a "real barriers effect," caused by various barriers to market integration. The second is a sticky-consumer-price cum volatile exchange-rate effect. Both are shown to be important empirically, the second type especially so. We argue that the two effects are very different from each other. For the first type of ...

How wide is the border?
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 significant amount of the variation in the prices of similar goods in different cities. But, the variation of the price is much higher for two cities located in different countries than for two equidistant cities in the same country. By our most conservative measure, crossing the border adds as much to the ...

How wide is the border?
Previous tests of stock index arbitrage models have rejected the no-arbitrage constraint imposed by these models. This paper provides a detailed analysis of actual S&P 500 arbitrage trades and directly relates these trades to the predictions of index arbitrage models. An analysis of arbitrage trades suggests that (i) short sale rules are unlikely to restrict arbitrage, (ii) the opportunity cost of arbitrage funds exceeds the Treasury Bill rate, and (iii) the average price discrepancy captured by arbitrage trades is small. Tests of the models provide some support for a version of the arbitrage ...

Real exchange rates and sectoral productivity in the Eurozone
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 dynamic general equilibrium model to generate a cross-section and time series of real exchange rates that can be directly compared to the data. Under the assumption of a common currency, estimates from simulated regressions are very similar to the empirical estimates for the Eurozone. Our findings contrast ...

Relative price volatility: what role does the border play?
We reexamine the effect of the U.S.-Canadian border on integration of markets. The paper updates work from our earlier paper, Engel and Rogers (1996). We consider alternative measures of deviations from the law of one price. We pay special attention to the effect of the U.S.-Canada free trade agreement on market integration. Our conclusions are unchanged: markets in the U.S. and Canada are more segmented than can be explained by the physical distance between the two locations. Formal trade barriers do not appear to explain much of that segmentation.
