The purpose of this study is to examine Technical Efficiency level smallholder barley production and also investigate socioeconomic determinants explaining the variation in among farmers using 488 random sample farm households Ethiopia. employed Maximum Likelihood estimation technique Cobb Douglas Stochastic Frontier Model that one most commonly used models empirical studies agricultural analys...

The study focused on the production cost efficiency and profitability of Abakaliki rice in Ihialia Local Government Area of Anambra State, Nigeria.. A random sampling technique was employed to select a total of 100 Abakaliki rice farmers from the study area. Data collection was achieved through the administration of structured questionnaire assisted with personal interview. Data analysis was do...

Abstract Shrimp aquaculture systems vary from primitive (extensive/improved extensive) to more industrialized (intensive/semi‐intensive) farms, and the impacts of environmental shocks may differ between them. This article applies Cobb–Douglas stochastic production frontier function evaluate determinants that impact inefficiency these intensive extensive in Vietnam. Data is a survey 436 white‐le...

Data Envelopment Analysis (DEA) provides means for piecewise linear approximation of production functions. To improve the fit to the data we propose to improve the flexibility of the frontier by extending DEA towards a more general piecewise quadratic approximation, called Quadratic Data Envelopment Analysis (QDEA). In contrast to the linear approximation, the quadratic approximation allows for...

This study evaluated profit efficiency of soybeans production in Federal Capital Territory, Nigeria. Multi-stage sampling technique was adopted for this study. Data were collected through the use well-structured questionnaire. The questionnaire distributed to 188 sampled soybean farmers area. data analyzed using descriptive statistics, gross margin analysis, financial Cobb-Douglas functional mo...

Abstract Climate adaptation is an essential strategy for responding to climate change at local levels and required sustainable food production meet the growing demand. In this light, study analyzed effects of strategies on technical efficiency maize farmers in Northern Ghana. This involved a total 619 that were selected through multistage sampling procedure. A Cobb-Douglas stochastic frontier w...

In this paper a re-examination of the original time-series data sets used by Professor Douglas and associated researchers to establish the existence of an aggregate production function is undertaken. Particular attention is paid to the issue of whether the data provide deductive support for the ‘Laws of Production’ as claimed by Douglas (1948). Various statistical methods are used to analyse th...

This paper uses the concept of Meta-frontier to investigate the relationship between Meta Technology Ratios (MTR) and different varieties in datepalms including; Mazafati, Rabi and Zardan that are produced widely in Sistan and Baluchestan province of Iran. We used a stratified sampling of 300 date farmers of this province in 2010, 2011 and 2012 and estimated a stochastic production frontier usi...

The estimation of frontier cost and production functions has been given impetus by the introduction of the stochastic frontier.’ This model is distinguished by a disturbance term composed of two parts a one-sided component, non-positive for production functions and non-negative for cost functions, representing the degree of inefficiency, and a symmetric component representing the usual statisti...

This study was conducted to assess the comparative efficiency of Aftab Bahumukhi Farm Limited (ABFL) supervised broiler farms and farmers’ own managed broiler farms. Data were collected from randomly selected 90 broiler farmers of which 45 were ABFL supervised farmers and 45 were own managed farmers. Cobb-Douglas stochastic production function and cost frontier function were applied to determin...
