This study was conducted to assess the technical efficiency of malt barley production in Malga District southern Ethiopia using cross-sectional data. Three stages sampling technique applied draw 186 sample farmers randomly. The interview schedule pre-tested before conducting actual data collection; gathered from households with help trained enumerators. In addition, secondary were collected thr...

We propose a two-stage stochastic variational inequality model to deal with random variables in variational inequalities, and formulate this model as a two-stage stochastic programming with recourse by using an expected residual minimization (ERM) solution procedure. The solvability, differentiability and convexity of the two-stage stochastic programming and the convergence of its sample averag...

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...

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...

Cassava is one of the most important cash crops in Cambodia. Agricultural mechanization promotes productivity, but overinvestment may disrupt balance between inputs and outputs. Depending on production scale, sometimes hiring equipment considered better than purchasing it. While we can hypothesize that investments might be crucial factors technical efficiency analysis for estimating their effec...

This paper estimates a stochastic production frontier using time-series data for the aggregate Korean economy in 1977-2005 to examine whether public infrastructure stock reduces aggregate technical inefficiency in the gross domestic product. A stochastic production frontier is estimated in first-differenced form, and the one-sided residuals are regressed against the stock of public infrastructu...

An optimal consumption problem is studied in a growth model for the Cobb-Douglas production function in a finite horizon. The problem is transfered into a stochastic Ramsey problem so as to reduce the dimension of the state space. The corresponding state equation is a stochastic differential ∗The second author is supported in part by a start-up fund at University of Oxford, and RGC Earmarked Gr...

Vegetable production constitutes an important sub-sector of the agricultural economy of KwaZulu-Natal. Most vegetables are cultivated in mixed-cropping types of farming systems. The technical efficiency of vegetable based cropping systems was estimated in order to identify the potential increase in production without incurring additional costs. The factors affecting technical efficiency and con...

the different model specifications have been proposed to estimate time-varying technical efficiency in the last two decades. these models have resulted different efficiency scores based on their built-in specifications. this study investigates the temporal pattern of technical efficiency based on cornwell, sickles, and schmidt (css, 1990) as well as lee and schmidt (ls, 1993) models. in order t...
