Is Per Capıta Real GDP Stationary in High Income OECD Countrıes? Evidence from Panel Unıt Root Test With Multiple Structural Breaks

Aim of this study is to analyze the non-stationarity of real GDP levels using recently developed Carrion-i Silvestre et al. (2005) panel unit root test allowing different number of structural breaks in panel. For this purpose, this test is applied to panel data of per capita GDP of 20 high income OECD countries covering the time period of 1961 through 2012. Individual time series and first generation panel unit root tests are also employed to make a comparison. Results indicate that per capita GDP series is non-stationary for many OECD countries. This implies that any shock given to per capita GDP will have a long lasting impact on the macroeconomic variabl
