The paper analyses scale efficiency in European pork production. The analysis shows significant differences in the exploitation of economies of scale among EU member states. In particular, old member states exhibit increasing returns to scale whereas most new member states show either constant...

The paper presents the analysis of cereal production in the EU. The analysis provides the comparison of production technologies and technical efficiency among EU countries using the country specific multiple output distance function models in the first step and metafrontier approach in the...

The paper deals with the analysis of productivity and efficiency differences between Czech and Slovak milk producers. The estimate of stochastic metafrontier multiple output distance function revealed that both Czech and Slovak milk producers highly exploit their production possibilities. On the...

We analyse the relative competitiveness between organic and conventional farming under different policy scenarios using a DEA-based non-convex metafrontier model. This model allows us to identify a farm’s ex post optimal technology based on input-output observations. Results for Bavarian dairy...

Taking the underlying technology heterogeneity into account, this paper uses a nonparametric metafrontier approach to estimate the CO2 emission efficiency and the potential emission reduction of China’s 30 provinces for the period 2006–2010. The sources of the potential emission reduction...

This paper analyzes the energy efficiency of China's 30 administrative regions during the period from 1997 to 2010. Most existing studies ignored the variation of production technologies among regions in China. Taking this factor into account, we introduce a parametric metafrontier approach...
