Abstract: This paper examines the persistence of Greek nominal and real variables under the Bretton Woods system and the post-1975 floating rate system. Two non-parametric measures of persistence are employed. The first is Cochrane's variance ratio test, put forward in 1988, which allows the decomposition of a series into a random walk and a stationary component; and the second is the modified rescaled range statistic, put forward by Lo in 1991, which tests for the existence of long-term dependence. Empirical findings suggest that some of the variables under consideration exhibit a higher persistence under floating while for the rest of them the tests do not indicate any significant change.
