We estimate the determinants of various types of product innovation. Knowledge spillovers from rivals have a positive impact on incremental innovations. This impact is largely independent of the participation in R&D cooperations. Spillovers exert no such independent influence on drastic...

In this paper it is tested which of the various alternative approaches for constructing knowledge spillover pools suggested in existing literature measures the extent to which a firm can costlessly receive external knowlegde best. Since knowledge spillovers are unmeasurable, a 'goodness of fit'...

The increasing commercialization of university discoveries has initiated a controversy on the impacts for future scientific research. It has been argued that an increasing orientation towards commercialization may have a negative impact on more fundamental research efforts in science. Several...

In this paper we analyse the decision of firms in the Canadian manufacturing sector to co-operate on innovation projects. Our focus is on the motives behind this decision and the firm characteristics, both general and with respect to innovation activities, which influence the motives for...

The internationalisation of corporate R&D opens up the chances to participate in international knowledge sharing. This increasingly motivates firms to accelerate the pace and extent of their international R&D activities in order to enhance innovativeness and consequently competitiveness and...

This paper analyzes the importance of equity finance for the R&D activity of small and medium-sized enterprises. We use information on almost 6000 German SMEs from a company survey. Using the intensity of banking competition at the district level as instrument to control for endogeneity, we find...

In the following paragraphs we will discuss the "mapping of innovative clusters in national innovation systems". For this we have used a data set of almost 3.000 firms that participated in the first and fifth survey of the Mannheimer Innovation Survey (which is comparable with CIS data). The...
