The study was conducted to indicate the determinants of technical efficiency of the dairy farmers in Ada’a district of Oromia state, Ethiopia. The study was arranged in four purposively selected peasant associations of the peri-urban and four kebeles of the urban dairy production sub-systems from which thirty dairy farmers were selected randomly. A total of two hundred forty respondents were pe...

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 ...

The set of Cobb-Douglas production functions is usually fitted by first linearizing the models through logarithmic transformation and then applying method of least squares. However, this procedure is valid only when the underlying assumption of multiplicative error-terms is justified. Unfortunately, this assumption is rarely satisfied in practice and accordingly, the results obtained are of dou...

Data envelopment analysis (DEA), originally developed to study production efficiency ofmicro-level organizations, has recently been used to adopt a production-frontier approach to the analysis of international macroeconomic growth and convergence patterns. DEA methods, however, are known to provide biased estimates of the production frontier and efficiency. We employ recent results from the sta...

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...

in this study, farm level technical efficiency (te) and its determinants were investigated. a stochastic cobb-douglas (cd) production frontier was used to provide estimates of input-oriented te for a sample of 100 rain fed farms in two palestinian governorates. empirical findings showed that the estimated te of the farms in the pooled sample ranged from 35.7 to 95.6%, with a mean value of 72.2%...

Growing social concerns over the environmental externalities associated with business activities are pushing firms to identify activities that create economic value with less environmental impact and to become more eco-efficient. Over the past two decades, researchers have increasingly used frontier efficiency models to evaluate productive efficiency in the presence of undesirable outputs, such...

the aim of this study is to investigate the context by which veterinary services may affect technical efficiency (te) of iranian dairy farms. a data envelopment analysis (dea) was applied to a random sample of 840 dairy farms from six provinces across iran to estimate regional frontier and metafrontier production functions and also to calculate corresponding te of these farms. the relationship ...

the present paper investigates the effect of production factors, including technology, physical capital and labour on the energy consumption intensity of iran. for this purpose, time series data during the period of (1974-2007) have been analyzed within cobb–douglas production function framework. the results of the study indicate that the technology and the physical capital have caused the aver...
