We study the dynamics of good-by-good real exchange rates using a micro-panel of 270 goods prices drawn from major cities in 63 countries and 258 goods prices drawn from 13 major U.S. cities. We find the half-life of deviations from the Law-of-One-Price for the average good is about 1 year. The average half-life is very similar across the OECD, the LCD and within the U.S., suggesting little in the way of nominal exchange rate regime influences. The average non-traded good has a half-life of 1.9 years compared to 1.2 years for traded-goods, for the OECD, with modest differences elsewhere. Aggregating the micro-data increases persistence in the OECD by 6 months to 1.5 years, well below levels obtained using aggregate CPI data. We attribute these differences to conceptual and methodological factors and argue in favor of increased use of micro-price data in applied theory.
