Title: AVRUPA BIRLİĞİ ÜLKELERINDE REEL KİŞİ BAŞINA GSYİH DURAĞAN MI? NON-LINEAR PANEL BIRIM KÖK TESTİ
Abstract: It is important for policy makers and economists whether or not the real per capita GDP is stationary.Nowadays, because of the panel unit root tests have over traditional unit root tests, the presence of unit root in the GDP series is under re-examination.The research presented in this paper applies the recently developed unit root test for nonlinear heterogeneous panel in order to re-examine whether or not the real per capita GDP follows a stationary process for 15 European Union member states over the period 1970-2011.Empirical evidence shows that the real per capita GDP is nonlinear-stationary for the EU-15 member states.
