This study examines the productivity changes of decision making units in situation where input price vectors are varying between them and inputs are heterogeneous; that is a noncompetitive market. We present a directional measure of cost Malmquist productivity index where incorporates the decision maker's preference over productivity change over time. A simple numerical example is designed to i...

This paper attempts to analyse the total factor productivity (TFP) growth rate in Malaysia during 1971 – 2004 and to discuss factors that determine TFP growth. Data envelopment analysis (DEA) approach is used to estimate the changes in the production frontier. The Malmquist productivity index has decomposed total factor productivity into technological change (TECHCH) and technical efficiency ch...

In order to realize economic and social green development, to pave a pathway towards China’s green regional development and develop effective scientific policy to assist in building green cities and countries, it is necessary to put forward a relatively accurate, scientific and concise green assessment method. The research uses the CCR (A. Charnes & W. W. Cooper & E. Rhodes) Data Envelopment An...

Multi-period differences of technical and financial performances are analyzed by comparing five North African railways over the period 1990–2004. A first approach is based on Malmquist DEA TFP index for measuring total factors productivity change, decomposed into efficiency change technological changes. multiple criteria analysis also performed using PROMETHEE II method ARGOS software. These me...

This paper uses the Luenberger productivity index to evaluate the productivity changes of Greek Life insurance companies between 1994 and 2003, combining operational and financial variables. It is found that the average annual productivity change was about 19% and was due to technological progress, whereas the impact of efficiency was minimal. It seems that deregulation, established by the Thir...

It is known that inability of the farmers to exploit available production technologies results in lower efficiencies production. So, measurement technical efficiency agricultural crops developing countries like India gained renewed attention since late 1980s from an increasing number researchers. Accordingly, present study has employed Data Envelopment Analysis (DEA) and Malmquist Total Factor ...

Taiwan and Korea are in fierce competition in the TFT-LCD panel industry and together dominate over 70% of the international market share. Business strategies in Taiwan primarily rely on Original Equipment Manufacturers (OEMs) whereas Korea focuses principally on vertical integration, including development of its own international brand architecture. Additionally the financial structures of the...

Data envelopment analysis (DEA) is a method for measuring the efficiency of peer decision making units (DMUs). Recently network DEA models been developed to examine the efficiency of DMUs with internal structures. The internal network structures range from a simple two-stage process to a complex system where multiple divisions are linked together with intermediate measures. In general, there ar...

energy, due to its increasing usage in various broad areas has been maintained as a vital factor in economic growth and development of societies. meanwhile, natural gas is considered as one of the most important energy sources. therefore, the efficiency and the productivity of the gas companies are crucial to be assessed. numerous examples from industrial multistage processes including internal...
