“…Many researchers examine the Feldstein-Horioka puzzle by using panel data together with the panel cointegration approach (e.g., Jansen, 2000;Corbin, 2001;Ho (2002); Kim et al (2005); Kollias et al (2006); Chakrabarti (2006); Christopoulos (2007); Adedeji and Thornton (2008); ; Bangake and Eggoh (2011);Ketenci (2013)). 2 Instead of adopting the panel cointegration approach, a number of researchers focus on the role of policy regime changes (see, for example, Ho (2000); Parmaksiz (, 2003a, 2003b); Telatar et al, (2007); Hatemi-J and Hacker (2007); Kejriwal (2008); Rao et al (2010); Ketenci (2012)). The main findings of these researchers suggest that policy regime changes introduce structural breaks which provide stronger evidence of cointegration between the investment and saving variables in the case of structural break accommodation compared to the case where the presence of structural breaks is ignored.…”
