A METAFRONTIER MODEL. Let the inputs and outputs for farms in a given farms are such that stochastic frontier production function models are appropriate for

Abstract. Agricultural productivity in Africa from 1971 to 2000 is examined using the recently developed metafrontier function technique, for the purpose of studying differences in efficiency and technology gap across different regions of the continent. The results support the view that technology gap plays an important part in explaining the

Journal of Productivity Analysis, 21, 91 - 103 . Objective: The objective of this study was to evaluate productivity growth and quality changes among different levels of accredited hospitals. Design: This study used an attribute-incorporating Malmquist productivity index (MPI) under the metafrontier framework. This is the first attempt to compare productivity changes among hospitals operating under different production frontiers. This paper uses a metafrontier model to analyse the difference in health care food efficiency across the various Australian regions. The interesting feature of this model is that it allows for the estimation of firms' efficiency in of various groups that might differ in technology and other production environments.

The metafrontier model enables the calculation of comparable technical efficiencies for firms operating under different technologies. The model also enables the

metafrontier, which is assumed to be a smooth function that envelopes the speciﬁc male, female and jointly managed plots' stochastic frontiers (Battese and Rao, 2002). However, metafrontier estimation requires parameters obtained from initial stochastic frontier analysis. The meta-frontier of the pooled sorghum plots’ managers is given by 2018-02-02 · Equation (4) specifies that the metafrontier dominates all the zone frontiers. The metafrontier production function as specified by equation (3) is a log linear production functional form, and the constraint imposed in equation (4) does not allow the metafrontier function to fall below the Using the firm-level data of sugar mills in 42 regencies in Indonesia from 2010 to 2014, this study applies the meta stochastic frontier based on the input distance function.

metafrontier can be classified into two components. The first component is a distance measurement from an input ‐output point to the group frontier, namely, technical efficiency (TE).The second component is a distance measurement between the group frontier and the metafrontier, namely, Technological Gap Ratios (TGRs).

Journal of Statistics and Management Systems: Vol. 21, No. 7, pp. 1251-1272. 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.

By means of this approach, it is possible to detect performance differences in the European health care systems subject to different conditions and technologies relative to the potential technology available. Empirical metafrontier studies based on stochastic frontier analy- sis have been presented by Bos & Schmiedel (2007), Lee & Hwang (2011) and Moreira & Bravo-Ureta (2010), among others. Meanwhile, this basic metafrontier framework has been ex- tended in several directions: one example is the transposition to a 2013-11-01 · A more in-depth analysis of innovative plants requires a more deliberate examination. There are two types of innovative plants: group and metafrontier innovative power plants.

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.
