Productivity has an important and effective role in the growth of production increasing competitiveness countries. In this study, using Malmquist productivity index, total trend factors three sectors Iranian economy (agriculture, industry services) during years 2012-2017 have been discussed. The results showed that study period changes all economic except industrial sector are due to technologi...

The Trade Offs approach is an advanced tool for the improvement of the discrimination of Data Envelopment Analysis (DEA) models, Meta Malmquist Index was defined by Maria Portella and et. al (2008). In this paper we compute the Meta Malmquist Index in Trade Offs model in DEA and we compare, obtaining results, of Meta Malmquist Index in different models of DEA, Variable Return to Scale (VRS), Co...

although economic and managerial literature is replete with studies that probe about productivity but only a few studies decompose it to its components (technological changes, managerial efficiency changes and scale efficiency changes)and analysis their share in productivity changes (positively or negatively). accordingly, this article attempts to explain the issue by decompose productivity to ...

This study seeks to determine the impact of mergers on efficiency and productivity of commercial banks in Malaysia for the period from 1995 until 2005. The study uses a non-parametric approach, namely DEA, to estimate the efficiency scores and to construct the Malmquist productivity index. To enable this estimation, three bank inputs and outputs were used. Amongst the findings are that banks ex...

Purpose: The sources of economic growth include capital, labor and the Solow surplus, dedicated to study (1956). surplus is inexplicable part with capital expressed as technological advances. also means total factor productivity (TFP). In other words, explained by TFP depending on technology from past present. These days, digitalization known be new revolution. light this concept, aims demonstr...

Malmquist Productivity Index (MPI) is a numeric index that is of great importance in measuring productivity and its changes. In recent years, tools like DEA have been utilized for determining MPI. In the present paper, some models are recommended for calculating MPI when there are just ratio data available. Then, using DEA and DEA-R, some models are proposed under the constant returns to scale ...

In measuring productivity in the presence of undesirable outputs, traditional growth accounting and index number approaches face the problem that prices of the undesirable outputs typically do not exist since such outputs are generally not marketed. In this paper we employ an alternative measure of total factor productivity based on a generalization of the Shephard distance functions, namely wh...
