چکیده

Previous studies of the so-called frontier production function have not utilized an adequate characterization of the disturbance term for such a model. In this paper we provide an appropriate specification, by defining the disturbance term as the sum of symmetric normal and (negative) half-normal random variables. Various aspects of maximum-likelihood estimation for the coefficients of a production function with an additive disturbance term of this sort are then considered.

Stochastic Non-Parametric Frontier Analysis

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...

Impact of Energy Subsidies Elimination on Technology Gap Ratio in Cucumber Production

This paper presents an analysis of technical efficiency and technology gap ratio (TGR) in greenhouse cucumber in Fars Province, Iran. Cucumber production was chosen for this study for the reason that greenhouse productions in this provincemainly have focused on this product. The data used in this study was obtained from a random sample of 127 greenhouses in Fars Province for 2010 to 2011. Metaf...

The Measurement and Comparison of Technical Efficiency Between Public and private Textile Industry in Iran

This paper is concerned with the estimation of frontier production function to measure the technical efficiency for Iranian textile companies during 1995. The objective of this estimation is to investigate if there are any differences in the technical efficiency between the private and public firms as well as the relationship between technical efficiency and size of textile companies in Iran. A...
