“…The non-frontier parametric approach is known as the production function approach and the frontier non-parametric approach is popularly known as the growth accounting approach. Due to certain limitations, such as the assumption of constant returns to scale and perfect market conditions, the semi-parametric approach, such as the Levinsohn–Petrin (L-P) approach, has become popular over the years to estimate TFP (Blalock & Gertler, 2004; Coricelli, Driffield, Pal & Rolland, 2012; Ghosh, 2009; Kato, 2009; Sharma, 2014; Vial, 2006). Although the literature on the estimation of productivity is quite developed (see Balakrishnan & Pushpangadan, 1998; Beveren, 2012; Bontemps, Robin & Berg, 2000; Good, Nadiri & Sickles, 1996), studies on firm-specific determinants of productivity are scarce.…”
