This paper provides an empirical demonstration for a practical approach of efficiency evaluation against the background of limited data availability in some regulated industries. Here, traditional DEA may result in a lack of discriminatory power when high numbers of variables but only limited...

In this paper, we analyze the technical efficiency of CO2 reduction potentials of German power and heat plants, using a non-parametric sequential Data Envelopment Analysis. We apply a metafrontier framework to evaluate plant-level efficiencies in the transformation of inputs into desirable...

As the Argentinean grapevine production systems have gained global visibility, the wine industry has been revitalized with a greater focus on enological quality, technology adoption, and export orientation. Although grapevine production has decreased 36% in a decade nationwide, the province of...
