In some data envelopment analysis (DEA) applications, some inputs of DMUs have negative values with positive cost. This paper generalizes the global cost Malmquist productivity index to compare the productivity of different DMUs with negative inputs in any two periods of times under variable returns to scale (VRS) technology, and then the generalized index is decomposed to several components. T...

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...

This paper ranks the pension funds management companies according to their change in total productivity for the period 1994–2007. We estimate the change in total productivity, breaking this down into technically efficient change and technological change by means of data envelopment analysis (DEA-Malmquist index). The aim of this procedure is to seek out those best practices that will lead to im...

The study examines the changes to total factor productivity of Jamaican banks between 1998 and 2007. Using Data Envelopment Analysis with bootstrap to construct a Malmquist index, bank productivity is measured and decomposed into technical progress and efficiency. The results suggest an inconsistent growth pattern for banks between 1998 and 2007 driven mainly by efficiency gains in the immediat...

an integrative approach of data envelopment analysis (dea) and malmquist productivity indicator for performance analysis of projects in subsea r&d; center (srdc) is presented. it is noticeable that, an output based model with constant efficiency was used for data analysis. furthermore, since the dea approach is merely used for homogeneous units, it was assumed that all the projects according to...

a r t i c l e i n f o Keywords: Malmquist–Luenberger index Urban water utilities Greenhouse gas emissions Nonparametric productivity measurement The energy use and greenhouse gas emissions in the provision of urban water and sewerage services have become an increasingly important issue in recent times. However, the impact of negative externalities such as greenhouse gas emissions on the product...

BACKGROUND This study is an initial effort to examine the dynamics of efficiency and productivity in Greek public hospitals during the first phase of the crisis 2009-2012. Data were collected by the Ministry of Health after several quality controls ensuring comparability and validity of hospital inputs and outputs. Productivity is estimated using the Malmquist Indicator, decomposing the estimat...
