technical efﬁciency); and a component that Given \(X_{jit}\), the metafrontier is defined as the upper boundary of the support of the distribution of \(f_{t}^{j} \left( {X_{jit} } \right)\), i.e., \(f_{t}^{M} \left( {X_{jit} } \right) = \sup \left( {f_{t}^{j} \left( {X_{jit} } \right) \, \begin{array}{*{20}c} | \\ | \\ \end{array} \, G\left( {f_{t}^{j} \left( {X_{jit} } \right)} \right) < 1} \right)\) where \(G\left( {f_{t}^{j} \left( {X_{jit} } \right)} \right)\) is the distribution function of \(f_{t}^{j} … The metafrontier is defined as the area of an unlimited production technology set. In addition, group frontiers are proposed to be the areas of limited production technology sets. The metafrontier model is used to highlight heterogeneity among clusters of countries revealing catch up phenomena. The estimation procedure is based on the notion of stochastic ordering and relies on the solution of an optimization problem on the parameters’ posterior means. The metafrontier framework proposed by O'Donnell et al. enables the evaluation of relative efficiencies for decision‐making units (DMUs) operating under heterogeneous technologies. The metatechnology ratio ( MTR ) constructed under the metafrontier framework helps estimate the gap between group frontiers and the metafrontier, with its score between 0 and 1.

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. To investigate knowledge transfer efficiency, this study applies a metafrontier epsilon‐based measure (EBM) model to survey data for 102 Chinese and African multinational enterprises (C–A MNEs). The results are as follows. (1) Only 14 of the 102 C–A MNEs have an efficiency score of 1. metafrontier in order to identify technological superiority of the countries against each other.

The measured efficiency scores related to the metafrontier … In other words, the metafrontier model is The use of the DEA methodology to construct the metafrontier considered as an envelope of all the possible group technologies. model is possible as long as we can identify separate frontiers for For example, if a particular output, y, can be produced using input different groups in the data set (O’Donnell et al., 2007). 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.
