One weakness of such tests, however, is that they fail to inform the researcher as … a small number of real exchange rates in a given panel may drive the results. In this paper we examine the PPP … when applied to a set of established panel-unit-root tests, allows the identification of the real exchange rates that are …

Panel unit root tests of real exchange rates as opposed to univariate tests usually reject non-stationarity. These … correlation matrix affect the size of first and second generation panel unit root tests.
