Here, we consider the problem of aggregation of efficiency and productivity indices. We will summarize some of the existing results and will derive new results for aggregation of Hicks-Moorsteen productivity indices.

In this article we generalize the aggregation theory in efficiency and productivity analysis by deriving solutions to the problem of aggregation of individual scale efficiency measures, primal and dual, into aggregate primal and dual scale efficiency measures of a group (e.g., industry). The new...

In this article, we revisit a recent work on pricing decision-making units by F&aauml;re et al (2013) and extend it to allow for non-constant returns to scale technologies.
