Evidence of Purchasing Power Parity for the Floating Regime Period

  • Claude Lopez

Abstract

This paper investigates the PPP hypothesis within industrialized countries for the post-Bretton Woods period via two panel unit root tests, the DF-GLS-SUR and the ADF-SUR tests, respectively developed by Lopez (2003) and Levin, Lin and Chu (2002). Both approaches allow for data specific serial and contemporaneous correlation. The results lead to two major conclusions. First, by comparing the two test outcomes, we show the importance of the test power on PPP evidence. Then focusing on the results obtained via the DF-GLS-SUR test, we provide reliably strong evidence of PPP for the floating regime period.
