This paper provides a cross-country efficiency analysis of electricity distribution companies in East European … transition countries (Poland, Czech Republic, Slovakia and Hungary). We compare the relative technical efficiency of East … European regional distribution companies (RDCs) among themselves, as well as with German RDCs. We use the nonparametric DEA …

The traditional approach to measuring allocative efficiency is based on input prices, which are rarely known at the … firm level. This paper proposes a new approach to measure allocative efficiency which is based on the output …-oriented distance to the frontier in a profit - technical efficiency space - and which does not require information on input prices. To …
