Total factor productivity of twenty OECD countries for a recent period (1971-2002) is explained using six different models based on the established literature. Traditionally, entrepreneurship is not dealt with in these models. In the present paper it is shown that – when this variable is added...

The bulk of Germany's research and development (R&D) activity is concentrated in densely populated areas, urban regions that account for 62 percent of the country's R&D workforce. The regions surrounding Stuttgart, Munich, and Braunschweig have by far the highest R&D intensity-that is, the share...

Forschung und Entwicklung (FuE) sind in Deutschland auf die Verdichtungsräume konzentriert, 62 Prozent des FuE-Personals sind dort tätig. Bei der FuE-Intensität - also dem Anteil der FuE-Beschäftigten an allen Erwerbstätigen - führen mit großem Abstand die Regionen Stuttgart, München und...

We estimate a model of international technological spillovers that allows for both international and inter-sectoral technology transfer, as well as international and intersectoral synergies in research and development (R&D). Furthermore we allow for a dynamic interaction in explaining total...

Workers have different abilities in research, development and innovation (R&D&I) activities. Firms have different “prospects for innovation”. Innovation is facilitated by matching innovators, i.e. workers that are specialized in R&D&I to firms with good prospects for innovation. Aggregate...

This paper addresses the impact of endogenous technology through research and development (R&D) and learning by doing (LbD) on the timing of environmental policy. We develop two models, the first with technological change through R&D and the second with LbD. We study the interaction between...

Evidence points to relatively low supply elasticities for workers skilled for research and development (R&D), which can hamper innovation and growth. Increasing the supply of R&D skills will expand an economy's innovative capacity. A simultaneous effect of increased education, which is...

It is obvious that the German economy exhibits a significant decline in economic growth during the last two decades. Although the German economy has still to overcome the burden of the reunification in 1990 it is shown that this burden might be only one reason of this decline. In this study we...

This paper investigates empirically different ways to organize R&D within Swiss firms. Based on a longitudinal data set comprising three cross-sections (1999, 2002, and 2005) of the Swiss innovation survey, four different types of R&D strategies were identified: firms combine in-house R&D with...
