Abstract:
|
We use historical data that cover more than one century on real GDP for industrial
countries and employ the Pesaran panel unit root test that allows for cross-sectional
dependence to test for a unit root on real GDP. We find strong evidence
against the unit root null. Our results are robust to the chosen group of countries
and the sample period.
Key words: real GDP stationarity, cross-sectional dependence, CIPS test.
