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.

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...

Shephard’s distance functions are widely used instruments for characterizing technology and for estimating efficiency in contemporary economic theory and practice. Recently, they have been generalized by the Luenberger shortage function, or Chambers-Chung-Färe directional distance function....

This note shows that the Nerlovian profit indicator may be aggregated over firms into an industry measure of profit efficiency. The note also provides conditions under which the technical component of the indicator may also be aggregated.

The discussion about the bias due to input (or output) aggregation in efficiency measurement based on data envelopment analysis, recently revisited by Tauer (2001) and Fare and Zelenyuk (2002) is continued. Attention is focused on the direction and the bounds of the aggregation bias.

We used advances in data envelopment analysis (DEA) techniques to examine efficiency scores and investigate the issue of convergence and divergence in a cross-country analysis. Specifically, we used bootstrapping techniques to examine a data set of 52 developed and developing countries. We found...

In this paper we consider estimation of models popular in efficiency and productivity analysis (such as the stochastic frontier model, truncated regression model, etc.) via the local maximum likelihood method, generalizing this method here to allow for not only continuous but also discrete...

The banking sector plays a major role in any economy, and it played a critical role in transition of Ukraine to a market economy. In this work, we investigate the hypothesis that, despite the tremendous growth and apparent prosperity that existed before the country was hit by the global...
