This study examined land tenure systems and rice productivity in Nigeria. Primary data were used for the study. Data collected with aid of a well-structured questionnaire. A four-stage sampling technique was to select total sample size three hundred forty-nine (349) farmers analysed using descriptive statistics, factor productivity, Stochastic production frontier model. The revealed that large ...

The study was aimed at analysing the technical efficiency in maize production of smallholder farmers in central rift valley of Ethiopia. Cross sectional data from 138 maize producer farmers were collected during 2011/12 production season. The estimated results of the Cobb-Douglas frontier model with inefficiency variables shows that the mean technical efficiency of the farmers in the production...

Using three-wave survey data for four villages of Jiangsu Province in China, the present paper examines whether and to what extent off-farm employment affects the technical efficiency of agricultural production. The level of technical efficiency is measured using a stochastic frontier production function approach. Based on estimation results from instrumental variable panel quantile regressions...

The growing awareness on the multiple environmental impacts of livestock production has risen the necessity to widen the definition of efficiency to a multidimensional eco-efficiency concept. Our paper suggests a combined approach of a whole-farm agronomic model and frontier efficiency method to explore deeply the determinants of eco-efficiency. The whole-farm model used, GAMEDE, is randomly pa...

Abstract Stochastic frontiers are a very popular tool used to compare production units in terms of efficiency. The parameters this class models usually estimated through the use classic maximum likelihood method even, last years, some authors suggested conceive and estimate productive frontier within quantile regression framework. main advantages approach lie weaker assumptions about data distr...

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...

The purpose of this paper is to construct a dynamic stochastic production frontier incorporating the sluggish adjustment of inputs, to measure the speed of adjustment of output, and to compare the technical efficiency estimates from this dynamic model to those from a static model. By assuming instantaneous adjustment of all inputs, a static model may underestimate technical efficiency of a prod...
