A COMPARATIVE STUDY ON TOTAL FACTORS PRODUCTIVITY PERFORMANCE OF CELLULAR FIRMS IN PAKISTAN

Abstract

This study empirically measures the total factors productivity (TFP) of three cellular firms i.e. Paktel, Pakcom and Mobilink operating in Pakistan. For the purpose of analysis, time series data (2000q1-2006q2) has been taken. For all three firms TFP is taken as dependent variable while output, teledensity, geographical areas covered and competition were taken as independent variables. By using the multiple regression models in log-linear form we obtained the positive and significant impact of all variables in all cases except competition that showed its impact negative in case of Paktel and Pakcom and geographical area that was insignificant in case of Mobilink.
