This study presents some quantitative evidence from a number of simulation experiments on the accuracy of the productivity growth estimates derived from growth accounting (GA) and frontier-based methods (namely Data envelopment Analysis-, Corrected ordinary least squares-, and Stochastic Frontier Analysis-based Malmquist indices) under various conditions. These include the presence of technical...

Data envelopment analysis (DEA) is an axiomatic, mathematical programming approach to productive efficiency analysis and performance measurement. This paper shows that DEA can be interpreted as a nonparametric least squares regression subject to shape constraints on production frontier and sign constraints on residuals. Thus, DEA can be seen as a nonparametric counter-part of the corrected ordi...

the aim of this paper is to use the concept of the metafrontier function to study the determination of efficiency differentials and technological gap ratio (tgr) on wheat production in khorasan razavi province. in this study, we used the metafrontier function and group frontier based on the concept of stochastic nonparametric envelopment of data analysis (stoned). the data used in this study co...

This paper simultaneously explores the determinants of the developing countries’ production frontier and their ‘efficiency’ in using the available resources and technology. In doing so it allows for the transfer of (industrial country) technology in determining the frontier and for international trade to influence absorptive capacity and national efficiency levels. Stochastic frontier analysis ...

The study was carried out to provide empirical evidence on technical efficiency of maize production in Nigeria using parametric and non-parametric approaches. The study employed annual secondary data on maize production in Nigeria from 1971 to 2010.Stochastic Frontier Analysis (SFA) and Data Envelopment Analysis (DEA) were used to estimate the technical efficiency of maize production. The resul...

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...

Abstract We propose a novel penalized splines method to estimate stochastic frontier model in which the is linear and inefficiency has single index structure with unknown link function index. The approach more flexible than traditional methodology requiring parametric and, at same time, it does not incur curse of dimensionality as fully non-parametric approach. procedure can be easily implement...
