TLDR
In this paper, a modified version of DEA based upon comparison of efficient DMUs relative to a reference technology spanned by all other units is developed, which provides a framework for ranking efficient units and facilitates comparison with rankings based on parametric methods.Abstract:
Data Envelopment Analysis DEA evaluates the relative efficiency of decision-making units DMUs but does not allow for a ranking of the efficient units themselves. A modified version of DEA based upon comparison of efficient DMUs relative to a reference technology spanned by all other units is developed. The procedure provides a framework for ranking efficient units and facilitates comparison with rankings based on parametric methods.read more

Ownership-efficiency relationship and the measurement selection bias: R. Bozec et al./Accounting and Finance 46 (2006)
TL;DR: In this paper, the bias in the selection of performance measures for ownership comparisons, which depends on the specific objectives of the firms being compared, is analyzed. And the results clearly support the view that privatization has no impact on a firm's technical efficiency, the only positive impact being related to a change in the objectives of a firm while using profitability measures.

Performance Measurement and Resource Allocation
TL;DR: A number of studies have documented that public and private sector organisations do not use their limited resources efficiently as mentioned in this paper, and suggested remedies range from industry reforms such as restructuring and deregulation to promote competition, to institutional changes such as adoption of efficient management practices.
Competitividad y eficiencia.
TL;DR: In this article, the authors developed a general vision of fundamentals of the more extended methods to analyse efficiency as the most controllable way to reach competitiveness and clarified the conceptual difference between competitiveness and efficiency establishing their relationship.

Impacts of heterogenous technological innovations on green productivity: An empirical study from 261 cities in China
TL;DR: Wang et al. as mentioned in this paper investigated the effects of different technological innovations on green productivity in 261 Chinese cities from 2004 to 2017, and employed the super-efficiency Epsilon-based measure (EBM) model with undesirable outputs under meta frontier and a global Malmquist-Luenberger index.

How do price distortions of fossil energy sources affect China's green economic efficiency?
TL;DR: Wang et al. as discussed by the authors analyzed the impact of fossil energy price distortions on green economic efficiency (GEE) and developed differentiated regional energy pricing policies for the realization of China's green economy.

Measuring the efficiency of decision making units
TL;DR: A nonlinear (nonconvex) programming model provides a new definition of efficiency for use in evaluating activities of not-for-profit entities participating in public programs and methods for objectively determining weights by reference to the observational data for the multiple outputs and multiple inputs that characterize such programs.

Some Models for Estimating Technical and Scale Inefficiencies in Data Envelopment Analysis
TL;DR: The CCR ratio form introduced by Charnes, Cooper and Rhodes, as part of their Data Envelopment Analysis approach, comprehends both technical and scale inefficiencies via the optimal value of the ratio form, as obtained directly from the data without requiring a priori specification of weights and/or explicit delineation of assumed functional forms of relations between inputs and outputs as mentioned in this paper.

Measuring the technical efficiency of production
Rolf Färe,C. A. Knox Lovell +1 more
TL;DR: The purpose of this paper is to specify a set of properties such an efficiency measure should satisfy, to show that the widely used measure proposed by Farrell does not satisfy them, and to introduce a new measure that does satisfy these properties.

Polyhedral Cone-Ratio DEA Models with an illustrative application to large commercial banks
TL;DR: Polyhedral Cone-Ratio Data Envelopment Analysis Models generalizing the CCR Ratio Model are developed for situations with a finite number of DMUs and employing polyhedral cones of virtual multipliers as discussed by the authors.
