''Is Per Capita Real GDP Stationary? Evidence from Selected African Countries Based on More Powerful Nonlinear (Logistic) Unit Root Tests''
( 2005, Vol. 3 No.24 )
In this study we use a more powerful nonlinear (logistic) unit root test advanced by Leybourne et al. (1998) to investigate the time-series propertities of per capita real GDP for 26 selected African countries for the period 1960-2000. We strongly reject the null of unit root process for over one-third the countries. These empirical results have important policy implications for selected African countries.
