Sammanfattning: This study adopts the stochastic metafrontier approach to investigate the role of soil conservation in small-scale highland agriculture in Ethiopia
May 17, 2017 Does anyone know how to estimate a Meta-Frontier Production Function in Stata ? Any syntax ideas would help. The only work I have seen so

As the analyzing method, the stochastic frontier is used as well as the metafrontier. According to the frontier function scores in the subsectors, in small-scale firms MP, FDT and MEMSAS subsectors and in medium- and large-scale firms OCP, FDT and TSL subsectors are the most efficient subsectors. The study used the true random effect model and stochastic metafrontier analysis to estimate region level technical efficiency (TE) and technology gap ratio (TGR) in the two main grain-producing regions of Norway. The result of the analysis shows that farmers differ in performance and technology use. 2017-09-01 Abstract.

metafrontier is the nonconvex piecewise frontier, 1-B-3 . However, if the three groups arenot exhaustive, then other input–output combinations may be feasi-
The metafrontier model 24 makes it possible to calculate comparable technical efficiencies for agricultural farms that operate under different technologies. The main aim of this study was to compare tomato productivity of com-mercial and smallholder tomato farmers in the Nkomazi area, Mpumalanga, using a metafrontier analysis. Analogous to Battese et al. (J Prod Anal 21:91–103, 2004 ), the metafrontier production function allows for calculating comparable TE measures, which can be decomposed into group specific TE measures and technology gap ratios.

The metafrontier model 24 makes it possible to calculate comparable technical efficiencies for agricultural farms that operate under different technologies. The main aim of this study was to compare tomato productivity of com-mercial and smallholder tomato farmers in the Nkomazi area, Mpumalanga, using a metafrontier analysis. The empirical results for the metafrontier analysis shows an average group technical efficiency (GE) score of 70.2% and average meta-technical efficiency of 56.7%. The community group recorded the highest efficiency score of 88.1% with respect to the group frontier, while the parish group showed highest efficiency score of 63.3% relative to the metafrontier. Metafrontier a b s t r a c t This thearticle way and associated measuresmetafrontiers efficiency are obtained of from nonparametric estimates of underlying group-specific frontiers. Both convex and non-convex metasets have been applied, but the large majority of … 2018-05-31 This paper considers a stochastic metafrontier function to investigate the technical efficiencies of firms in different groups that may not have the same technology. A decomposition of output is presented involving the technology gap and technical efficiency ratios for firms in a group relative to the best practice in the industry.

(2004) is followed in this analysis. A metafrontier slack-based efficiency measure is presented to measure environmental efficiency for various regions in China. The objective of the new approach is to investigate the change of environmental efficiency while incorporating group heterogeneities and all variable slack and environmental pollutants into environmental efficiency analysis. Analogous to Battese et al.

However, metafrontier estimation requires parameters obtained from initial stochastic frontier analysis. The metafrontier of the pooled sorghum plots’ managers is given by: l n Q z ∗ i = β z ∗ 0 + 6 ∑ j = 1 β z ∗ j l n X z ∗ i j + ε z i j , j = 1,2,3 , … , j l n Q i z ∗ = β 0 z ∗ + ∑ j = 1 6 β j z ∗ l n X i j z ∗ + ε i j z , j = 1,2,3 , … , j
(J Prod Anal 21:91–103, 2004), the metafrontier production function allows for calculating comparable TE measures, which can be decomposed into group specific TE measures and technology gap ratios. This paper uses the concept of a metafrontier to compare the technical efficiencies of firms that may be classified into different groups. function is the meaning of the metafrontier function of firms/units (Battese, Rao, & O’ Donnell, 2004).
