In the existing literature, the theoretical models suggest that foreign-owned firms perform better than domestic firms and that private sector firms perform better than public sector firms. The present study is a modest attempt in this regard to empirically test and compare the differences in the technical and scale efficiencies of 36 public limited companies, private sector firms and foreign firms belonging to the pharmaceutical industry of India using the DEA model. The analysis shows that overall technical efficiency was different in the case of private domestic and public sector firms in the year 1990, i.e., the pre-reform period. The difference was also significant in the case of private foreign and public sector firms, though it was not significant in the case of private domestic and private foreign firms in the pre-reform period. However, in the subsequent post-reform years, there were no significant differences.

The regional competitiveness is the source of national competitiveness and the efficiency measuring and relative regional efficiency comparison are crucial questions for analysts as well as for economic policy creators. Regional competitiveness becomes a subject of evaluation due to increasing significance of regions in concept of European Union. This paper deals with the application of parametric benchmarking method – Stochastic Frontier Analysis (SFA) for measuring technical efficiency of NUTS2 regions of V4 countries within the time period of 8 years.

This study adopted two-stage DEA to estimate the technical efficiency scores and assess the impact of the two most important components of fossil fuel associated with oil production on macroeconomic efficiency of Seven oil producing African countries during 2005-2012. Our results showed that increasing the consumption of natural gas would improve technical efficiency. Furthermore, increasing the share of fossil fuel in total energy consumption has negative effect on the efficiency of the economies of the top African oil producers. Also, we found that increasing the consumption of primary energy improves efficiency in these economies. We therefore, recommend that governments and other stakeholders in the energy industry should adopt inclusive strategies that will promote the use of natural gas in the short term. However, in the long-run, efforts should be geared towards increasing the use of primary energy, thereby reducing the percentage share of fossil fuel in total energy consumption.
