The determinants of the technical efficiency (TE) of adopters and non-adopters of soil and water conservation (SWC) technologies in the upper Rwizi micro-catchment of south-western Uganda are compared using cross-sectional survey data from 246 smallholder farmers. A Cobb-Douglas stochastic production frontier and a probit selection model fitted to generate inverse Mills ratios for adopters and ...
Red chili is one of the leading commodities that has high economic value, it also much needed and in demand by community. However, production productivity red chilies Sawang District, North Aceh Regency still low at 5.53 tons/ha, compared to average 13 tons/ha. The purpose this study was analyze factors influence technical efficiency farming Regency. Sampling carried out using census method, wh...
The field of production frontier estimation is divided between the parametric Stochastic Frontier Analysis (SFA) and the deterministic, nonparametric Data Envelopment Analysis (DEA). This paper explores an amalgam of DEA and SFA that melds a nonparametric frontier with a stochastic composite error. Our model imposes the standard SFA assumptions for the inefficiency and noise terms. The frontier...
walnut is one of the important products in kerman province and baft town is the main area of walnut orchards. so the technical, allocative and economical efficiency of walnut farmers computed assign the degree of farmer’s success in the optimum allocation of their resources. at first the proper production function was estimated, and then stochastic frontier production and technical, efficie...
By using a stochastic frontier framework, the mutual effect of input use on production risk and inefficiency is investigated. Disentangling this mutual effect proves important for empirical reasons, at least when applied to west Tennessee cotton systems grown after various cover crops. The most striking result is that the stochastic frontier model, when compared with a typical Just-Pope model, ...
Changes in soil texture after the Merapi eruption 2010 does not affect farmers using production factors, resulting non-optimal production. This study aims to analyze factors affecting red chili and level of technical, allocative, economic efficiency farming area, Sleman Regency Yogyakarta. utilized a quantitative method. A total 80 was selected as samples by simple random sampling Data were ana...
The current study deals with the technical efficiency of cotton farmers operating on Harran Plain Turkiye an application to two well-known stochastic approaches, i.e., Cobb-Douglas and translog frontier production functions. Using farm-level cross-sectional data, a specialized maximum likelihood technique incorporates both frontiers inefficiency effects models into single equation model estimat...
We consider the case of production units arranged into a number of groups. All units within a group choose output-input combinations from the same production possibilities set, which is represented by a stochastic frontier model. The metafrontier is the envelope (over groups) of the group-specific frontiers. We are interested in the unit’s inefficiency relative to its group-specific frontier, b...
