“…Previous research on the methodological domain of EC has evaluated trends by mostly considering empirical studies only. A number of attempts have been made by previous researchers to understand the methodologies adopted; for instance, two stage least square method (Frankel and Romer, 1999; Morgan, 2013), constant market share model (Joshi and Singh, 2012), simple general equilibrium model of EC (Helpman, 1984), RCA (Qureshi and Wan, 2008), MNL model (Rettab and Rao, 2009), gravity model (Bergstrand, 1985; Fink et al , 2005), tobit model (Kumar and Siddharthan, 1994), auto regressive conditional heteroscedasticity model (McKenzie and Brooks, 1997), GARCH model (Kroner and Lastrapes, 1993), probit, logit and tobit and MNL logistic (Hung et al , 2004). We make a strong point here that authors should compile more studies to put forward a more comprehensive integration of all the relevant facets of the methodological domain.…”
