This paper investigates the determinants of the real exchange rate using a panel of disaggregated data for the OECD countries. It also marries two literatures - one which uses panel data to measure relationships between changes in exchange rates to changes in the determinants, and the other which uses cointegration techniques to measure the long-run relationship between the level of the exchange rate and the level of the determining factors. The previous panel studies cannot account for deviations from long-run trend levels, while the extant literature using time series cointegration techniques can only intermittently detect and measure posited relationships. Estimating the relationships in levels is an interesting activity because it allows one to calculate trend real exchange rates. Aft...
