“…The empirical evidence from this literature is however mixed and controversial across countries, data, model specifications and econometric techniques. While some studies (Ram, 1987;Ahsan et al, 1996;Cotsomitis et al, 1996;Thornton, 1999;Islam, 2001;Al-Faris, 2002;Chang, 2002;Aregbeyen, 2006;Srinivasan, 2013;Bayrak and Esen, 2014) found support for Wagner's Law, other studies (Ansari et al, 1997;Biswal et al, 1999;Ghali, 1999;Burney, 2002;Huang, 2006) reported results contradicting Wagner's law. Some other studies (Singh & Sahni, 1984;Ahsan et al, 1992;Afxentiou & Serletis, 1996;Sinha, 1998;Bagdigen & Cetintas, 2004;Dogan & Tang, 2006) showed no evidence for both propositions.…”
