abstract research and development (r&d;) spending plays a major role in innovation, raising productivity and increasing economic growth. the purpose of this paper is to investigate the impact of r&d; spending on growth and total factor productivity (tfp) in iran's agricultural sector. we estimate growth and productivity models using auto-regressive distributed lag (ardl) approach and data over ...

This paper discusses those sources of endogenous growth arising from labor as labor. It uses a production function which models the returns to scale as a function of the division of labor and learning. Smithian analysis of the labor process constitutes the basis upon which we build our own approach. © 2001 Elsevier Science B.V. All rights reserved. JEL classification: D24; J24; O41

Innovation plays a crucial role in improving firm's performance. The relationship between innovation and productivity has been widely analysed during this decade across countries industries, generating important new findings. This study aims to provide an overall literature review on the of firms obtain comprehensive overview changing productivity. By reviewing existing empirical evidence, one ...

Cost complementarities arise from synergies in the production of heterogeneous goods. It is shown that synergies can be accounted for in terms of shared public inputs (roughly) if and only if synergies decrease as the scope of production increases. This case of ‘‘substitutive’’ synergies is argued to be typical. The key technical tool is a novel interpretation of conjugate Moebius inversion in ...

We explore the relation between the establishment of a regulatory agency and the performance of the electricity sector. We exploit a dataset comprising firmlevel information on a representative sample of 220 electric utilities from 51 development countries for the period 1985 to 2005. Our results indicate that regulatory agencies are associated with more efficient firms and with higher social w...

abstract o ur basic aim in this paper concerns the question that if overusing the information technology by service and manufacturing firms can increase the total productivity resulting from this kind of technology regarding the iran's economic structure and conditions. for this purpose, we primarily evaluate the productivity resulting from the rate of firms' use of it for the differe...

This paper studies the relationship between three measures of relative earnings and firm performance based on data of 664 listed manufacturing companies in China over the period 2005-2012. It finds that (1) capital earnings relative to labor earnings and the overall average wage level relative to a firm’s average wage level had negative effects on firm performance; (2) the earnings of high-leve...

Three dimensions of the performance of firms in Ghana’s manufacturing sector are investigated in this paper: their technology and the importance of technical and allocative efficiency. We show that the diversity of factor choices in not due to a non-homothetic technology. Observable skills are not quantitatively important as determinants of productivity. Technical inefficiency is not lower in f...
