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 ...

Approximately 60-70% of all recombinant human glycoproteins are produced in Chinese Hamster Ovary (CHO) cells. Production in CHO cells, however, is often plagued by low productivity when compared with other host cell lines, including bacteria and yeast. For this reason, investigating ways of improving the productivity of CHO cells producing recombinant proteins has been an active area of resear...

In this chapter Iparraguirre D’Elia outlines the productivity performance of Northern Ireland between 995 and 00 . The results indicate that while Northern Ireland returned the highest rate of economic growth of all UK regions between 989 and 00 , its productivity performance has been poor, with most of the economic growth over this period being attributable to increasing employment levels. Nor...

Exporting is often touted as a way to increase economic growth. This paper examines the interaction between exporting and productivity growth in US manufacturing. While exporting plants have substantially higher productivity levels, there is no evidence that exporting increases plant productivity growth rates. The higher productivity of exporters largely predates their entry into exporting. How...

This paper provides parametric estimates of technical change, e¢ ciency change, economies of scale, and total factor productivity growth for large banks (those with assets in excess of $1 billion) in the United States, over the period from 2000 to 2005. In doing so, we propose a distance function based primal total factor productivity growth index, which is valid under both perfect and imperfec...

What factors underlie industry differences in research intensity and productivity growth? We develop a multisector growth model using standard parameters to capture the main factors considered in the empirical R&D and productivity growth literature. Along the balanced growth path, we find that the primary factor behind industry differences in productivity growth is the extent to which new knowl...

Two models where productivity growth is caused by spillovers from R&D are analysed using a sample of nine manufacturing industries in six large OECD-countries between 1979 and 1991. The first model is based on traditional productivity analysis where growth in R&D stocks causes productivity growth. The second model is based on the endogenous growth literature where the level of R&D expenditures ...

a r t i c l e i n f o This paper presents a theoretical model of firm-specific productivity growth that incorporates technological knowledge by electrification and tests the model empirically. Our theoretical explanations suggest that the energy-transformation from fossil fuel to electricity by electrification could cause a decrease in the short-term level of productivity but an increase in the...

In this paper the Malmquist index of total factor productivity is applied to a sample of 87 countries observed over the period 1960-90. This index and the method needed to quantify it, the data envelopment analysis, has substantial advantages as compared to traditional growth accounting. Two of these advantages are that it does not rely on questionable equilibrium assumptions to merge multiple ...

This study examines the impact of productivity growth on the relationship between inflation and unemployment in Canada. Recently it has been suggested that higher productivity growth is responsible for a shift in the U.S. Phillips curve that occurred in the late 1990s. This paper examines whether the Phillips curve in Canada shifted in a manner similar to that of the United States, and the degr...
