Decomposition and Aggregation of Tone Efficiencies

karagiannis, giannis - 2022

In this paper we concern with the decomposition and aggregation of cost efficiencies when input prices vary across decision-making units. In this respect, we first examine the relations among the components of the existing decompositions as well as with other efficiency measures. We also derive...
