We examine the geographic co-location of university research and industrial R&D in three technology areas. While we find strong evidence of co-location of these vertically connected activities, regional economies appear to vary markedly in their ability to convert local academic research into local commercial innovation. We develop and test the hypothesis that the presence of a large, local, R&...

This paper investigates labor productivity growth and the contribution to labor productivity growth in Swedish manufacturing during electrification and the ICT revolution. The paper distinguishes between technology-producing, intensive and less intensive technology-using industries during these technological breakthroughs. The results show that labor productivity growth and the overall contribu...

Using micro evidence from manufacturing and services firms located in 55 African countries, this paper shows that better management practice, reflected by international management certification, helps firms to raise productivity. Larger and older firms and firms operating closer to the technological frontier are more likely to possess international management standards certification, as do firm...

The effects of O33 and O49 P. mirabilis lipopolysaccharides (LPSs) on human erythrocyte membrane properties were examined. Physical parameters of the plasma membrane, such as membrane lipid fluidity, physical state of membrane proteins, and osmotic fragility, were determined. The fluidity of the lipids was estimated using three spin-labeled stearic acids of doxyl derivatives: 5-doxylstearic aci...

This paper examines whether endogenous growth processes can be found in middle income country contexts. Estimation proceeds by means of dynamic heterogeneous panel analysis. Empirical evidence ...nds in favour of both knowledge spill-over e¤ects, and of positive impacts on total factor productivty growth by Schumpeterian innovative activity. A crucial ...nding is that spill-over e¤ects emerge f...

This paper revisits the induced innovation literature of the 1960s to which Phelps was a major contributor (Drandakis and Phelps, 1965). This literature was the first systematic study of the determinants of technical change and also the first investigation of the relationship between factor prices and technical change. I present a modern reformulation of this literature based on the tools devel...

I adopt the distribution dynamics framework to study labor productivity convergence, in the period 1980-1995, among 28 developed and developing countries, in different manufacturing sub-sectors, identified, as according their technological content into Resource Based, Low Technology, Medium Technology and High Technology. I find that, exception made for High Technology and Manufacturing as a wh...

We analyze the implications of entrepreneurial spawning for a variety of firm characteristics such as size, focus, profitability, and innovativeness. We examine the dynamics of spawning over time. Our model accounts for much of the empirical evidence relating to the relation between spawning and firm characteristics. Firms that have higher patent quality spawn more, as do firms that have higher...

There is substantial empirical evidence that innovation is geographically concentrated. Unlike what is generally assumed, however, it is not clear that localised knowledge spillovers provide a theoretically valid explanation for this. Studying spillovers of cost-reducing technology between Cournot oligopolists we show that 1) localised knowledge spillovers of any level do encourage agglomeratio...
