The Metafrontier MalmquistLuenberger productivity index - (MML index) is used to shed on these issues which light embody the contribution of this paper to the literature. The rest of this study is organized as follows. In Section we introduce the 2,

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.

A graph of the metafrontier function is presented in Figure 1. Results indicate that male-managed sorghum plots had the highest metafrontier technical efficiencies (MTEs) (61%, 56% and 15%) and technology gap ratios (TGRs) (98%, 92% and 20%) for Lira, Serere and Kumi districts, respectively compared to female and jointly managed plots. employed metafrontier approach, developed by Battese and Rao (2002) and O'Donnell et al.(2008) in this study.

Several studies employ the metafrontier to be the main method in their research, emphasizing on the measurement of technical efficiency (TE) and technical gap ratio (TGRs). The metafrontier is assumed to employ the same technology [ 13] as the individual stochastic frontiers in different groups. In this manner, the upper boundary now faced by all hospitals is the metafrontier, instead of the individual group frontiers. This paper uses the concept of a metafrontier to compare the technical efficiencies of firms that may be classified into different groups. The metafrontier technique consists of enveloping the groups of frontiers estimated through another frontier, called metatechnology.

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.

In this paper a semiparametric stochastic metafrontier approach is used to obtain insight into the performance of manufacturing firms in Europe. We differ from standard TFP studies at the firm level as we simul- taneously allow for inefficiency, noise and do not impose a functional form on the input–output relation. 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 Metafrontier Productivity Indices: Questioning the Common Convexiﬁcation Strategy Qianying Jin∗ Kristiaan Kerstens† Ignace Van de Woestyne‡ 15th May 2019 Abstract While the construction of metafrontiers based on the union of underlying group fron- A metafrontier production function for estimation of technical efficiencies and technology gaps for firms operating under different technologies.

According to Battese and Rao , a metafrontier is defined as the boundary of a production possibility set of all input-output combinations, whereas group frontiers are conceptualized as the subboundaries of production possibility sets of groups of firms.
