We conduct an empirical analysis of the technical efficiency of cars sold in Germany in 2010. The analysis is performed using traditional data envelopment analysis (DEA) as well as directional distance functions (DDF). The approach of DDF allows incorporating the reduction of carbon dioxide...

Since the 1990s, efficiency and benchmarking analysis has increasingly been used in network utilities research and regulation. A recurrent concern is the effect of environmental factors that are beyond the influence of firms (observable heterogeneity) and factors that are not identifiable...

The current food crisis all over the globe has necessitated alternative policy actions byvarious stakeholders in almost all countries of the world. Consequently, efforts are focusedon increased investment in agricultural research and development. The study evaluatesimpact of technological...

This article presents multi-output, multi-input total factor productivity (TFP) growth rates in agriculture for 88 countries over the 1970–2001 period, estimated with both stochastic frontier analysis (SFA) and the more commonly employed data envelopment analysis (DEA). We find results with...

We investigate how the intensity of competition among airports affects their technical efficiency by computing airports’ markets on the basis of a potential demand approach. We find that the intensity of competition has a negative impact on airports’ efficiency in Italy during the...
