In this paper, we focus on the efficiency performance of the Vietnamese commercial banks in terms of their efficiency change, productivity growth, and technological change during the period 2001–2003. We use a data envelopment analysis (DEA) model for this purpose. Productivity is measured using the Malmquist total factor productivity index. The panel data of 13 commercial banks in Vietnam are ...

In many real applications, the data of production processes can't be precisely measured.We develop some fuzzy versions of the classical DEA models (in particular, the CCRmodel) by using some ranking methods based on the comparison of cuts. Our approachescan be seen as an extension of the DEA methodology. The provides users and practitionerswith models which represent some real life processes mo...

Wheat is a major agricultural crop in the Sistan region with a key role in local economy. The present study aimed to economically explore the efficiency of wheat production over the 2014-2016 period with the window data envelopment analysis (WDEA) approach. Also, the Malmquist productivity index was employed to assess the productivity of wheat growers in the study site under variable return to ...

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 wi...

U.S. hospitals are under continual pressure both to increase productivity and to improve quality through the use of Health Information Technology. This paper analyzes 3,187 US hospitals, using data reported to the American Hospital Association, to assess changes in productivity over a fiveyear period (2002-2006). The Malmquist Indices derived indicate that Total Factor Productivity (TFP) and Ef...

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 dierent 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. th...
