This study investigates the stochastic convergence behaviour of real GDP per capita for the period 1948-2010 and 1900-2010 across the 20 OECD countries. For that purpose, the existence of stochastic convergence is estimated by technique basedon the Fourier function approach (FKPSS) stationary test developed by Becker, Enders and Lee(2006). As well as, Fouier IPS test was applied for the whole panel. The Fourier KPSS stationarity test results produced different results for both periods. While the results of the analysis strongly supported the stochaticcon vergence for all countires except Austria and Belgium for the period 1948-2010, it only supported for Austria, Canada, Fnland, France, Netherlands, New Zealand, Norway, Sweden, Switzerland, UK and USA during 1900-2010. The Fourier IPS test results for the entire panel support a stochactic on vergence for both periods. It is also observed that the Standart deviation values for o-convergence tent to decrease for the whole period. According to the results obtained, it is the most important finding of this study that the differences in real per capita incomes during the post-war period are largely eliminated in the oECD countries and that long-term country-specific shocks have a temporary effect on real per capita income.
