Abstract

The paper tests for PPP by investigating into the real exchange rates of seven South Asian countries. It employs two univariate unit root tests, namely, the ADF and the PP tests and two panel unit root tests, namely, the IPS and the CIPS tests. The univariate tests overwhelmingly fail to reject the unit root null. The IPS test also reinforces this result. The CIPS test that takes into account of cross section dependence produces mixed results. The findings, on the whole, fail to support stationarity of the South Asian real exchange rates and hence, PPP does not seem to be a valid proposition for the region.
