This study evaluates the role market competition plays in determining inflation based on sector-level data from OECD countries. In theory, trade openness can affect inflation through changes in market competitiveness and productivity. Nonetheless, previous empirical studies often fail to account...

Previous findings of long-run purchasing power parity come mainly from data for industrial countries, raising the issue of whether the results suffer sample-selection bias and exaggerate the general relevance of parity reversion. This study uncovers substantial cross-country heterogeneity in the...

The conventional view, as expounded by sticky-price models, is that price adjustment determines the PPP reversion rate. This study examines the mechanism by which PPP deviations are corrected. Nominal exchange rate adjustment, not price adjustment, is shown to be the key engine governing the...

This study evaluates the individual roles of monetary and productivity shocks in real exchange rate fluctuations under the current float. Using a cointegration model of exchange rates and relative prices, the innovations are decomposed into transitory and common-trend parts. Both transitory and...

This study explores the sources of real exchange rate fluctuations under the current float. Using a cointegration model of the real exchange rate, the innovations are decomposed into transitory and common-trend components. Both transitory and common-trend innovations are found to explain an...
