TL;DR: In this paper, the authors investigate the achievements of the theoretical and practical basis of environmental policy analysis in order to study their works and point out the future possible research direction; they sort out researches about environmental efficiency assessment and review the works about the theory and application of efficiency analysis around the world.

TL;DR: In this article, a two-stage network DEA model was used to evaluate the efficiency of 16 major Chinese commercial banks during the third round of the Chinese banking reform period (2003-2011) with variable returns to scale setting and the consideration of undesirable/bad output.

TL;DR: The original DEA cross-efficiency concept is generalized to game cross efficiency, where each DMU is viewed as a player that seeks to maximize its own efficiency, under the condition that the cross efficiency of each of the other DMUs does not deteriorate.

TL;DR: This paper seeks to extend the model of Doyle and Green by introducing a number of different secondary objective functions, which provide a ranking among the decision-making units (DMUs) and eliminates unrealistic DEA weighting schemes without requiring a priori information on weight restrictions.

TL;DR: In this article, a modified variable returns to scale (VRS) model was proposed to evaluate the performance of the countries in Olympic games, where each DMU is viewed as a competitor via non-cooperative game and a multiplier bundle is determined that optimizes the efficiency score for that DMU.
