In previous studies, measures of technical inefficiency derived from stochastic production frontiers have been estimated from residuals which are sensitive to specification errors. This study corrects for this inaccuracy by extending the doubly heteroscedastic stochastic cost frontier suggested...

This paper uses Monte Carlo experimentation to investigate the finite sample properties of the maximum likelihood (ML) estimators of the half-normal stochastic frontier production functions in the presence of heteroscedasticity. It is found that when heteroscedasticity exists correcting for it...

The aim of this paper was to analyze the maize crop at the country and the Călăraşi county level and in the two companies submitted to the case study. This analysis highlighted the importance of the maize crop, crop that is being cultivated on large areas of the country and county, and that...

Profitability of the specialist beef production in the Australian Beef Industry is undertaken using a break-even model. The results reveal that during the financial years 1991-1996, the specialist beef producers were operating above the break-even level in the states of South Australia and to...

This paper aims to analyze the technical efficiency of farms in Brazil and its regions, based on the data from the 2006 Census of Agriculture. More specifically, it seeks to compare the technical efficiency of family farms in relation to business farms, considering the regional differences in...

This study describes the technical efficiency of sugarcane production and the factors affecting this efficiency. The study was conducted in Turiani Division, Mvomero District, Morogoro Region, Tanzania. Specifically, the study determined and compared the level of technical efficiency of...

Yeryüzü’nün ekolojik sisteminde iklim değişikliği nedeni ile ortaya çıkan değişmeler ile tarımsal ürün talebindeki artışların neden olduğu olumsuz etkiler hem Türkiye’de hem de Dünya’da tarım ürünleri piyasalarında dengesizlik eğilimlerini artırmıştır. Bu...

In this study, the production technology of sunflower crop was analyzed, by comparison, in Calarasi county and a company located in Baragan area. The technological system components were analyzed regarding the technology of sunflower crop, practiced in the farm subject to the case study, namely:...

Economic efficiency plays an important role in the foundation and farm level decisions, constituting a basic criterion in assessing the level of economic activity and development prospects. The study aimed to analyze the economic efficiency of crop production systems, measured through indicators...

The study aimed to identify growth prospects / preservation of economic efficiency in terms of interventions to increase performance and in shaping the directions in which this objective can be. For the study started from two methodological premises: vegetable production systems design adapted...
