TLDR
The current paper develops an additive efficiency decomposition approach wherein the overall efficiency is expressed as a (weighted) sum of the efficiencies of the individual stages and can be applied under both CRS and variable returns to scale (VRS) assumptions.About:

Equivalent solutions to additive two-stage network data envelopment analysis
Linyan Zhang,Yao Chen +1 more
TL;DR: The current study shows that the two approaches to solve additive two-stage network DEA model are equivalent and use the same parameter in searching for the global optimal solution.

A two-stage DEA model with partial impacts between inputs and outputs: application in refinery industries
TL;DR: A couple of new mathematical programming models in the DEA framework are formulated with the aim of considering partial impact between inputs and outputs for calculating aggregate, overall, and subunit efficiencies along with resource usage by production lines for a two-stage production system.

Corrigendum: Quantitative efficiency assessment based on the dynamic slack-based network data envelopment analysis for commercial banks in Ghana
TL;DR: In this article, the authors proposed a relative dynamic two-stage network data envelopment analysis model for measurement of bank efficiency based on the slack-based measure, which was used to identify the sources of inefficiency in the banks.

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.

Efficiency decomposition in two-stage data envelopment analysis: an application to non-life insurance companies in taiwan
Chiang Kao,Shiuh-Nan Hwang +1 more
TL;DR: The relational model developed in this paper is more reliable in measuring the efficiencies and consequently is capable of identifying the causes of inefficiency more accurately.

Profitability and Marketability of the Top 55 U.S. Commercial Banks
Lawrence M. Seiford,Joe Zhu +1 more
TL;DR: In this article, the authors examined the performance of the top 55 U.S. commercial banks via a two-stage production process that separates profitability and marketability and uncovered substantial performance inefficiency in both dimensions.
