“…Specifically, one strand of literature supports the evidence of strong positive linear effects (see for example Asteriou and Spanos, 2019;Adusei, 2019;Caporale et al, 2015;Loayza and Ranciere, 2006;Ketteni et al, 2007;McCaig and Stengos, 2005;Levine et al, 2000), while other studies by using threshold techniques claim that the relationship between financial development and economic growth is nonlinear (see among others Samargandi et al, 2015;Cecchetti and Kharroubi, 2012;Rioja and Valev 2004a,b;Deidda and Fattouh, 2002). Both approaches have important limitations since the former studies impose a specific functional form, while the latter techniques are sensitive to the threshold variable chosen (endogeneity issues).…”
