The accumulation of the human capital stock plays a key role to explain the macroeconomic performance across regions. However, despite the strong theoretical support for this claim, empirical evidence has been not very convincing, probably because of the low quality of the data. This paper...

The economic literature started to recognize the heterogeneity characterizing the nature of different technologies, introducing the concept of General Purpose Technologies. In this paper, we offer a new view of General Purpose Technologies, building on the historical as well as on the recent...

The accumulation of the human capital stock plays a key role to explain the macroeconomic performance across regions. However, despite the strong theoretical support for this claim, empirical evidence has been not very convincing, probably because of the low quality of the data. This paper...

We examine the contribution of human capital to economy-wide technological improvements through the two channels of innovation and imitation. We develop a theoretical model showing that skilled labor has a higher growth-enhancing effect closer to the technological frontier under the reasonable...

Panel data is used to investigate the extent of R&D spillovers between OECD countries, and the importance of barriers to technology adoption in affecting the benefits of such spillovers. Our results indicate that countries with less regulated goods and labour markets benefit more from foreign R&D.

In bedeutenden Modellen der neuen Wachstumstheorie wird Wachstum entweder durch eine zunehmende Produktvielfalt oder durch Qualitaetsverbesserungen bestehender Produkte modelliert. Wachstum im Romer- Modell (Romer (1990a)) basiert auf einer zunehmenden Anzahl von Produkten, bei Grossman und...

The paper focuses on the impact of business related R&D spending on input factor productivity (IFP) using international patent applications as a technology diffusion channel. Considering the relationship between research and productivity, international patent pattern reflects the link between...

Our paper decomposes knowledge-diffusing trade flows and estimates their impacts separately. Overall, trade generates positive knowledge spillovers, but the effects of intra-industry trade are ambiguous. With regard to sectoral import penetration, we find that potential positive spillovers are...

This paper develops a two-sector R&D-based growth model with congestion effects from increasing urban population density. We show that endogenous technologicalprogress causes structural change if there are positive productivity spillovers from the modern to the traditional sector and Engel’s...

Previous research on optimal R&D subsidies has focussed on the long run. This paper characterizes the optimal time path of R&D subsidization in a semi-endogenous growth model, by exploiting a recently developed numerical method. Starting from the steady state under current R&D subsidization in...
