“…Note that by imposing F(u i,t−1 ; Â i ) = 0 or F(u i,t−1 ; Â i ) = − i i where i is vector of level parameters, one obtains conventional linear cointegration equation (e.g., Kapetanios et al, 2006). Following earlier literature on nonlinear unit root and cointegration (e.g., Kapetanios et al, 2003Kapetanios et al, , 2006Ucar and Omay, 2009;Maki, 2010) Omay et al (2014 assumes that the transition function F(u i,t−1 ; Â i ) is of the exponential form 1 :…”
