Using partial factor productivity and data envelopment analysis approaches, this study measures and compares the operational efficiency of the 10 dominant mobile operators in Brazil, Russia, India and China (BRIC) between 2002 and 2006. The results of data envelopment analysis indicate that the...

This study analyzes the changes in carbon dioxide (CO2) emissions resulting from the movement of containers from established ports through the emerging port of Taipei in Northern Taiwan. An activity-based emissions model is used to estimate the CO2 emissions of container transport under four...

This paper shows that subsidy can naturally emerge as part of the equilibrium strategy of an innovator of a cost-reducing innovation in a Cournot oligopoly when the innovator is endowed with combinations of upfront fee and royalty. It is further shown that there are robust regions where the...
