How to properly decompose economic efficiency using technical and allocative criteria with non-homothetic DEA technologies
Aparicio, Juan; Pastor, Jesus T.; Zofio, Jose L. - In: European Journal of Operational Research 240 (2015) 3, pp. 882-891
We discuss how to properly decompose economic efficiency when the underlying technology is non-homothetic using … alternative allocative and technical efficiency criteria. We first show that only under the production of one output and assuming … measure pure technical efficiency. Otherwise, when non-homotheticity is assumed, we then show that these traditional …

Statistical inference for DEA estimators of directional distances
Simar, Léopold; Vanhems, Anne; Wilson, Paul W. - In: European Journal of Operational Research 220 (2012) 3, pp. 853-864
In productivity and efficiency analysis, the technical efficiency of a production unit is measured through its distance … viewed as additive (rather than multiplicative) measures efficiency. Directional distance functions are not restricted to non …

Multi-period efficiency and Malmquist productivity index in two-stage production systems
Kao, Chiang; Hwang, Shiuh-Nan - In: European Journal of Operational Research 232 (2014) 3, pp. 512-521
. Since the efficiency of a two-stage system in a period is the product of the two process efficiencies, the overall … efficiency of a decision making unit (DMU) in the specified period of time can be decomposed into the process efficiency of each …

Measurement of returns to scale using non-radial DEA models
Krivonozhko, Vladimir E.; Førsund, Finn R.; Lychev, … - In: European Journal of Operational Research 232 (2014) 3, pp. 664-670
There are some specific features of the non-radial data envelopment analysis (DEA) models which cause some problems for the returns to scale measurement. In the scientific literature on DEA, some methods were suggested to deal with the returns to scale measurement in the non-radial DEA models....

A postscript on aggregate Farrell efficiencies
Färe, Rolf; Karagiannis, Giannis - In: European Journal of Operational Research 233 (2014) 3, pp. 784-786
In this note we derive alternative weighting schemes that complement those of Färe and Zelenyuk (2003) for consistent aggregation of Farrell efficiencies when the technology exhibits (global) constant returns to scale.

Inverse DEA under inter-temporal dependence using multiple-objective programming
Jahanshahloo, G.R.; Soleimani-damaneh, M.; Ghobadi, S. - In: European Journal of Operational Research 240 (2015) 2, pp. 447-456
This paper deals with the inverse Data Envelopment Analysis (DEA) under inter-temporal dependence assumption. Both problems, input-estimation and output-estimation, are investigated. Necessary and sufficient conditions for input/output estimation are established utilizing Pareto and weak Pareto...
