| Tiivistelmä: | This paper re-examines the purchasing power parity hypothesis for the dollar-sterling exchange rate using the two centuries of data from Lothian and Taylor (1996) (LT). Unlike LT, the authors of this article conclude that the dollar-sterling RER is nonstationary, implying a rejection of the long-run PPP hypothesis. The differences in their conclusions are explained by: (1) sensitivity of ADF unit root tests to the choice of lag length, and/or (2) the presence of significant time trends in the ADF or Phillips-Perron unit root test equation. |
