TLDR
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.

Data Envelopment Analysis: A Comprehensive Text with Models, Applications, References and DEA-Solver Software

TL;DR: In this article, the basic CCR model and DEA models with restricted multipliers are discussed. But they do not consider the effect of non-discretionary and categorical variables.

A procedure for ranking efficient units in data envelopment analysis

TL;DR: 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.

Efficiency of financial institutions: International survey and directions for future research

TL;DR: The authors survey 130 studies that apply frontier efficiency analysis to financial institutions in 21 countries and find that the various efficiency methods do not necessarily yield consistent results and suggest some ways that these methods might be improved to bring about findings that are more consistent, accurate, and useful.

Estimation and inference in two-stage, semi-parametric models of production processes

TL;DR: In this paper, a coherent data-generating process (DGP) is described for nonparametric estimates of productive efficiency on environmental variables in two-stage procedures to account for exogenous factors that might affect firms’ performance.

Estimating Efficient Production Functions Under Increasing Returns to Scale

TL;DR: In this paper, a convex closure of a set of points in a space of a suitable number of dimensions is used to estimate the convexity of a given production function under constant returns to scale.

On the estimation of production frontiers : maximum likelihood estimation of the parameters of a discontinuous density function / 236

TL;DR: In this article, an asymmetric criterion function was proposed for regression estimation with asymmetric objective functions, which is similar to the one used in the present paper, but with a different objective function.
