The stochastic frontier production model is one of the most used ways to estimate efficiency and productivity. The purpose of this paper was to decompose the sources of total factor productivity (TFP) growth into technological progress, changes in technical efficiency and changes in economies of scale. In this paper, we also used Divisia index in order to estimate production function. A random ...

for assessment of portfolio performance, it's crucial to adjust the return by the risk which is taken. so it seems undeniable that for measuring the risk-adjusted return of portfolio, we need an appropriate and developed model for risk and asset pricing. fama & french 3 factor model could explain several return anomalies. recent studies show that capital productivity effects on stock retur...

The purpose of this paper is to estimate changes in productivity, technical efficiency and technology across the economic sectors during the period 1985-2006. We also seek to identify the turning points for productivity growth to see whether it was accompanied by technological change and/or technical efficiency. For estimating economic growth, aggregate production function is used. We find that...

bstract: The paper analyzes the efficiency and productivity of the Romanian banks from 2006-08. It uses a non-parametric approach, the data envelopment analysis (DEA) to analyze banks’ efficiency. Based on a sample of 15 commercial banks, our findings reveal that although the efficiency of the Romanian commercial banks improved since 2006, the cost efficiency scores are relatively low. Also, ev...

This paper focuses on the evolution of productivity in the telecommunications industries for 13 OECD countries over the period 1979-1998. It uses Data Envelopment Analysis, a non-parametric approach that allows decompositions of changes in productivity into variations in efficiency and technical change. Moreover, it tests the existence of convergence in labor and total factor productivity level...

f rom the viewpoint of economic theories, total factor productivity (tfp) is the most important component that leads to economic growth and development. the main purpose of this study was to evaluate the impact of knowledge-based economy on total factor productivity in the member countries of the middle east and north africa (mena) region. for this purpose, the panel data regression analysis ha...
