Are Real GDP Levels Trend, Difference, or Regime-Wise Trend Stationary? Evidence from Panel Data Tets Incorporating Structural Change
AbstractThe unit root hypothesis for international real GDP and real GDP per capita has been the subject of extensive investigation. Using panel methods that incorporate structural change, we reject the unit root null in favor of the alternative of trend stationarity, with one or two changes in the slope for two panels with postwar data and one or two changes in both the slope and the intercept for a panel with long-horizon data. We conclude that real GDP levels are better characterized as regime-wise trend stationary than as either trend stationary without structural change or difference stationary with unit roots.
