In this paper we develop an approach that synthesizes the best features of the two main methods in the estimation of production efficiency. Specically, our approach first allows for statistical noise, similar to Stochastic frontier analysis, and second, it allows modeling multiple-inputs-multiple-outputs technologies without imposing parametric assumptions on production relationship, similar to...

the aim of this paper is to analyze total factor productivity (tfp) growth and its components in asian countries applying stochastic frontier analysis (sfa) to the time series data of 44 asian countries from 2000 to 2010. using battese and coelli approach, tfp is divided into technical efficiency change and technical change. tfp decomposition using sfa method for the years 1998 to 2007 indicate...

The purpose of this paper is to investigate the levels of technical efficiency in agricultural sector of MENA countries by using Data Envelopment Analysis (DEA) and Stochastic Frontier Analysis (SFA) approaches in 2007-2008. The results show that the total average of technical efficiency is as follows: DEABCC(0.770)>DEACCR(0.744)>SFA(0.479), and among all MENA countries, the best performanc...

In this paper, copulas and Archimediean copulas (especially with hyperbolic generator) are investigated and it is shown how to use this type of functions in the stochastic frontier analysis. Then we study the efficiency of hydropower plants located on prominent dams in Iran, and based on their performance in 1399 we use data envelopment analysis and stochastic frontier analysis and copulas func...

this study examines the responsible energy consumption of listed european hotels. hotel efficiency is estimated using a stochastic frontier analysis (sfa) production function, with supplies costs as the input and total revenue as the output. cluster analysis is used to group the hotels into homogeneous groups according to their efficiency level, size, or profitability. the results show that the...
