Using partial factor productivity and data envelopment analysis approaches, this studymeasures and compares the operational efficiency of the 10 dominant mobile operators inBrazil, Russia, India and China (BRIC) between 2002 and 2006. The results of dataenvelopment analysis indicate that the two leading Brazilian mobile operators, Vivo andTIM, are fully efficient throughout the entireperiod of study; however, Indian mobile operatorsare the least efficient among BRIC operators. Interestingly, the findings of this study verifythat full operational efficiency can be achieved by operators with large revenues, such asChina Unicorn, and by others with medium and small revenues, such as Vivo, TIM and Oi.Partial factor productivity demonstrates that 3 of the 4 Brazilian mobile operators, Vivo,TIM and Oi, have remarkable productivity ratios, and that the state-owned operator, ChinaUnicorn, has the highest revenue per capital expenditure among BRIC operators. In contrast,Indian mobile operators ’productivity ratios are generally low compared to other BRICmobile carriers.
