Abstract

This article applies the model free, seasonality robust periodogram test, and the conventional augmented Dickey-Fuller (ADF) unit root test to the real exchange rates (RER) of the G-7 countries. The empirical results show that the periodogram test rejects the null of unit root for a larger number of countries compared to the ADF test.
