due to agriculture is a risky activity and risk models is important in order to analyze the behavior of farmers, hence, in this study, the factors affecting risk-taking and risk aversion is the region grape growers. data analysis was performed by using stochastic frontier. data gathered by questionnaires at three counties of zabol, hirmand and zahak at 265 grape farmers in crop year of 2011-201...

abstract quantitative analysis of production through evaluating the level of factor usage is a major part in agricultural management, which aims at increasing production by optimum usage of resources. this study has estimated and analyzed stochastic frontier production function and calculated technical efficiency of semi-mechanized broiler farms located in gorgan district. the survey data were ...

walnut is one of the important products in kerman province and baft town is the main area of ‎walnut orchards. so the technical, allocative and economical efficiency of walnut farmers computed ‎assign the degree of farmer’s success in the optimum allocation of their resources. at first the ‎proper production function was estimated, and then stochastic frontier production and technical, ‎efficie...

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...

this paper uses the concept of meta-frontier to investigate the relationship between meta technology ratios (mtr) and different varieties in datepalms including; mazafati, rabi and zardan that are produced widely in sistan and baluchestan province of iran. we used a stratified sampling of 300 date farmers of this province in 2010, 2011 and 2012 and estimated a stochastic production frontier usi...

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...

This paper examines several extensions of the stochastic frontier that account for unmeasured heterogeneity as well as firm inefficiency. The fixed effects model is extended to the stochastic frontier model using results that specifically employ its nonlinear specification. Based on Monte Carlo results, we find that the incidental parameters problem operates on the coefficient estimates in the ...

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...
