Up to now, in the development of power electronics systems, the reduction of the initial costs or the increase of the power density have been of primary concern. However, with increasing energy costs also the power conversion efficiency is gaining higher and higher importance. Accordingly, while maintaining high power density, an efficiency as high as possible must be obtained. In this paper th...

efficiency in agricultural production is indicative of the efficiency level of farm households in their farming activities. farmers in developing countries do not make use of all the potential technological resources, thus making inefficient decisions in their agricultural activities. herein, technical efficiency in relation with the production of three types of rice crop (boro, aus and aman) w...

climate change phenomenon is an important environmental challenge of the world. increasing extension of greenhouse gases and remote relationship phenomena accelerate the speed f climate change. changes in precipitation level, drought occurrence and changes in the level of surface and groundwater resources are the recognized consequences of climate change. in order to study consequences of clima...

We decompose labor productivity growth into components attributable to technological change, technological catch-up, foreign capital deepening, domestic capital deepening, and human capital accumulation, thus separating the effects of foreign and domestic capital deepening on productivity growth and convergence. We apply nonparametric production-frontier methods to a worldwide 1980-2005 panel a...

the aim of this paper is to study the impacts of technological progress and efficiency change on the productivity growth of iran agriculture separated by provinces. the period of this study is from 2005-2014. first of all, the impacts of efficiency change and technology change were separated using dea and malmquist model. then, their impacts on productivity growth were studied. it was concluded...

The purpose of this paper is twofold. First, in the framework of the strategic groups’ literature, it analyses changes in productivity and efficiency of Spanish private and savings banks over an eight-year period (1998–2006). Second, by adapting the decomposition of the Malmquist productivity indices suggested by Färe et al. (1994), it proposes similar components decomposing the Luenberger prod...
