background hospitals are highly resource-dependent settings, which spend a large proportion of healthcare financial resources. the analysis of hospital efficiency can provide insight into how scarce resources are used to create health values. this study examines the technical efficiency (te) of 12 teaching hospitals affiliated with tehran university of medical sciences (tums) between 1999 and 2...

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...

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 field of production frontier estimation is divided between the parametric Stochastic Frontier Analysis (SFA) and the deterministic, nonparametric Data Envelopment Analysis (DEA). This paper explores an amalgam of DEA and SFA that melds a nonparametric frontier with a stochastic composite error. Our model imposes the standard SFA assumptions for the inefficiency and noise terms. The frontier...

Electricity distribution network is a prime example of a natural local monopoly. In many countries, electricity distribution firms are regulated by the government. In Finland, the regulator estimates the efficient cost frontier using the data envelopment analysis (DEA) and stochastic frontier analysis (SFA) methods. This paper reports the main results of the research project commissioned by the...

Stochastic nonparametric envelopment of data (StoNED) combines the virtues of data envelopment analysis (DEA) and stochastic frontier analysis (SFA) into a unified framework of frontier estimation. StoNED melds the nonparametric piece-wise linear DEA-type frontier with stochastic SFA-type inefficiency and noise terms. We show that the StoNED model can be estimated in the panel data setting in a...

Although agenda of Water supply in sufficient quantity and standard quality is highlighted in India from last few years. But Yet Performance assessment and Efficiency evaluation of water supply services not in practice. However the analysis is confined to the realm of researchers and policy makers. The present paper spells inclusion of quality parameter in assessment of utilities through fronti...

Environmental performance of the U.S. States is investigated for the period of 1990 – 2007 using Stochastic Frontier Analysis (SFA). The SFA accounts for both efficiency measure and stochastic noise affecting a frontier. The frontier is formed using indicators of GDP, energy consumption, population, and CO2 emissions. For comparability, all indicators are expressed as ratios to total. Statistic...

Literature of productive efficiency analysis is currently divided between two main paradigms: the parametric Stochastic Frontier Analysis (SFA) and the deterministic, nonparametric Data Envelopment Analysis (DEA). This paper develops a new encompassing framework that melds the SFA-style stochastic composite error term to the DEA-type nonparametric frontier that satisfies monotonicity and concav...

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...
