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...

An attempt was made to determine the overall farm-specific technical efficiency or inefficiency of onion farms of Bangladesh. Farm-level data were used for the estimation of the parameters of Cobb-Douglas stochastic frontier production function. The model for technical inefficiency effects in the stochastic frontier included age, experience, education, and farm size. The elasticity of output wi...

When analyzing the productivity of rms one may want to compare how the rms transform a set of inputs x typically labor energy or capital into an output y typically a quantity of goods produced The economic e ciency of a rm is then de ned in terms of its ability of operating close to or on the production frontier which is the boundary of the production set The frontier function gives the maximal...

This study reports the results of farmers’ production via irrigation resources utilization and efficiency parameters technical allocative by way sustainable environmental economics. The hypothesis is that factors affect in scheme as Data from cross section panel data were used then productivity measurement function are outlined two scenarios: first, report such output elasticity determine ineff...

This study analyzed sea salt production and compared the technical efficiency level technology gap between traditional High-Density Polyethylene Geomembranes (HDPE GMB) in Phetchaburi province using a copula-based meta-stochastic frontier technique. A total sample size of 250 was chosen, comprising 195 farmers 55 HDPE GMBs farmers. Several copula families were used to analyze dependence structu...

When analyzing the productivity of rms, one may want to compare how the rms transform a set of inputs x (typically labor, energy or capital) into an output y (typically a quantity of goods produced). The economic eeciency of a rm is then deened in terms of its ability of operating close to or on the production frontier which is the boundary of the production set. The frontier function gives the...

A representative sample of 49 state and collective farms in Ukraine provides data in physical units on livestock and crop production and input use for 1989-92. The changes in production efficiency for beef, pork, dairy, winter wheat, grain, and potato production, investigated using stochastic frontier methods, show declining technical efficiency in livestock production and especially low margin...

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...

Education will have externality effects in agriculture if, in the course of conducting their own private economic activities, educated farmers raise the productivity of uneducated farmers with whom they come into contact. This paper seeks to determine the potential size and source of such benefits for rural areas of Ethiopia. Average and stochastic frontier production function methodologies are...
