Entropy based Malmquist Productivity Index in Data Envelopment Analysis

author

Abstract:

Malmquist Productivity Index (MPI) is one of the most famous indices, which is used for estimating the productivity change of a Decision Making Unit (DMU) during the time. Virtually any empirical study that uses MPI, reports average of the productivity indices they estimate to represent the overall tendency in productivity changes. In such a case, productivity indices of a DMU are considered with equal value. In this paper, we propose using the entropy of productivity indices of all DMUs at a specific part of time as the weight of indices of that in aggregating the indices during the under study time section. Then, we use the proposed method for an empirical study of 18 Iranian companies manufacturing automobiles and automobile parts, which have been accepted in Tehran Stock Exchange.

A global cost Malmquist productivity index using data envelopment analysis

This paper proposes a global cost Malmquist productivity index, new cost Malmquist productivity index, that is circular and that gives a single measure of productivity change. The index is inspired by the global Malmquist productivity index as extended to productivity measurement. Decomposition of the proposed cost Malmquist productivity index is presented. Numerical results are presented for a...

An ethics-based decomposition of Malmquist productivity index using data envelopment analysis

Productivity growth and efficiency improvements are the major sources of economic development. Pure efficiency, scale efficiency, and technology are basic factors, and rules and regulations and balance are recently known factors affecting the Malmquist productivity index. The index is the most common productivity growth index that uses data envelopment analysis models over multiple time periods...

Y.-M. Wang, Y.-X. Lan / Mathematical and Computer Modelling 54 (2011) 2760–2771 2761 TheDEA-basedMPI has proven to be a very useful tool formeasuring the productivity changes of DMUs in the past several decades. For instance, Färe et al. [13] applied it to analyze the productivity growth in industrialized countries. Grifell-Tatjé and Lovell [14] used it tomeasure the effect of deregulation on S...

The issue of input/output slacks in validating data envelopment analysis-based Malmquist productivity index: an example from banking

Data envelopment analysis (DEA) models have been used in formulating the Malmquist index to measure productivity change over time periods. In this article, we question the validity of this index in the presence of input/output slacks that appear in DEA models used. We demonstrate with an application to banking that Malmquist index loses its meaning whenever slacks are present. As a corrective m...

Malmquist productivity index in several time periods on interval data

The productivity change of a decision making unit (DMU) between two time periods can be evaluated by the Malmquist productivity index. In this study, we propose a method to compute the Malmquist productivity index in several time periods (from the first to the last periods) on interval data in data envelopment analysis (DEA). Then, the obtained Malmquist productivity index is compared with Malm...
