''Is volume index of gdp per capita stationary in oecd countries? panel stationary tests with structural breaks''
( 2009, Vol. 29 No.2 )
The purpose of this paper is to investigate whether volume index of GDP per capita is stationary for 24 OECD countries during the period 1970 to 2006. We utilize a panel stationary tests that allow for multiple structural breaks, developed by Carrion-i-Silvestre et al. (2005). The empirical findings are threefold: (1) when we employ univariate unit tests, such as ADF and KPSS without structural breaks, we hardly find evidence of I(0) stationarity, except for Switzerland (2) when we employ KPSS stationarity test with multiple structural breaks, we find evidence of I(0) stationarity for 22 out of 24 countries and (3) when we employ KPSS panel I(0) stationarity test with multiple structural breaks and the assumption of cross-section dependence, we find significant evidence of panel I(0) stationarity of per capita GDP for these OECD countries. The findings of this paper have implications for policymaking and econometric modeling for these 24 OECD countries.
