The nonparametric data envelopment analysis (DEA) model has become increasingly popular in the analysis of productive efficiency, and the number of empirical applications is now very large. Recent theoretical and mathematical research has also contributed to a deeper understanding of the seemingly simple but inherently complex DEA model. Less effort has, however, been directed toward comparisons between DEA and other competing efficiency analysis models. This paper undertakes a comparison of the DEA, the deterministic parametric (DFA), and the stochastic frontier (SFA) models. Efficiency comparisons across models in the above categories are done based on 15 Colombian cement plants observed during 1968–1988.read more

Environmental efficiency with multiple environmentally detrimental variables : estimated with SFA and DEA
TL;DR: In this paper, the authors compare two methods for the calculation of efficiency; namely Stochastic Frontier Analysis (SFA) and Data Envelopment Analysis (DEA), and reveal the strengths and weaknesses for estimating environmental efficiency of the methods applied.

Technical efficiency in farming: a meta-regression analysis
Boris E. Bravo-Ureta,Daniel Solis,Victor H. Moreira Lopez,José F. Maripani,José F. Maripani,Abdourahmane Thiam,Teodoro E. Rivas +6 more
TL;DR: In this article, a meta-regression analysis including 167 farm level technical efficiency (TE) studies of developing and developed countries was undertaken, and the econometric results suggest that stochastic frontier models generate lower mean TE (MTE) estimates than non-parametric deterministic models, while the primal approach is the most common technological representation.

Formulation and estimation of stochastic frontier production function models
TL;DR: In this paper, the authors define the disturbance term as the sum of symmetric normal and (negative) half-normal random variables, and consider various aspects of maximum-likelihood estimation for the coefficients of a production function with an additive disturbance term of this sort.

A Model for Technical Inefficiency Effects in a Stochastic Frontier Production Function for Panel Data
George E. Battese,Tim Coelli +1 more
TL;DR: In this paper, a stochastic frontier production function is defined for panel data on firms, in which the nonnegative technical inefficiency effects are assumed to be a function of firm-specific variables and time.

Frontier production functions, technical efficiency and panel data: With application to paddy farmers in India
George E. Battese,Tim Coelli +1 more
TL;DR: In this article, a stochastic frontier production function model for panel data is presented, for which the firm effects are an exponential function of time, and the best predictor for the technical efficiency of an individual firm at a particular time period is presented for this timevarying model.

A Generalized Production Frontier Approach for Estimating Determinants of Inefficiency in U.S. Dairy Farms
TL;DR: In this paper, the authors investigated farm-level efficiency of U.S. dairy farmers by estimating their technical and allocative efficiency, and found that levels of education of the farmer are important factors determining technical inefficiency and large farms are more efficient than small and medium-sized farms.
