Asymptotic redundance results for the use of GLS detrending in panel unit root testing
Professor Joakim Westerlund (Deakin University)
La Trobe University
One of the most well-known facts about unit root testing is that the Dickey-Fuller test based on OLS detrended data suffers from low power, and that the use of GLS detrending can lead to substantial power gains. The present paper shows how the use of GLS rather than OLS detrended data when testing for a unit root in panels not only leads to reduced power, but actually has an order effect on the neighbourhood around unit for which locala symptotic power is negligible.
