Incentives and assistance provided by TTOs, university policies, patent legislation and scientific disciplines are certainly part of the explanations for academic entrepreneurship. But they are only one facet of the story. Another facet is related to the scientists' motives, expectations and...

This policy paper on science-industry technology transfer has four emphases: the rationale of recent changes in German science policy, the contribution of diverse transfer channels to economic development as well as the role of IPR in that context, the differences in the institutional framework...

This paper develops theoretical standpoints to investigate and analyse university inventors and patenting activities. Although the studies on academic entrepreneurship and university patenting have substantially increased, first there have not been enough studies on individual inventors and...

This paper discusses several features of knowledge that are often considered crucial for characterizing the economic significance of knowledge: whether it is overtly accessible or tacit, whether it can be or is encoded or not, and whether it has public or private good character. It is argued...

This paper investigates the causes of the shortfall in private R+D expenditure of the EU compared to the US. It shows that differences in the structure of the two economies play only a minor role in explaining the R+D gap. Instead, the European R+D shortfall is mainly caused by a negative...

This paper addresses the question of whether government procurement can work as a de facto innovation policy tool. We develop an endogenous growth model with quality-improving innovation that incorporates industries with heterogeneous innovation sizes. Government demand in high-tech industries...

This paper analyzes whether firms conducting internal R&D and acquiring external high-tech equipment experience a complementarity effect. For German CIS data we conduct a complete set of indirect and direct complementarity tests refining the analysis by looking at various types of innovations...

This study is about structural change in the energy system. In a first step an econometric model is presented and in a second step diffusion of GTs is embedded theoretically. By focusing on different green technology industries (GT sector) in Germany, we analyze how policy induced demand...

This paper investigates the relevance of government purchasing behavior for innovation-based economic growth. We construct a parsimonious Schumpeterian growth model in which demand from the public sphere can effectively alter the economy's rate of technological change. We incorporate results of...
