Using firm-level data from the German manufacturing sector, we estimate a dynamic, structural model of the firm’s decision to invest in R&D and quantify the cost and longrun benefit of this investment. The model incorporates and quantifies linkages between the firm’s R&D investment, product...

R&D collaboration facilitates pooling of complementary skills, learning from the partner as well as sharing risks and costs. Research therefore repeatedly stressed the positive relationship between collaborative R&D and innovation performance. Fewer studies addressed potential drawbacks of...

R&D collaboration facilitates pooling of complementary skills, learning from the partner as well as sharing risks and costs. Research therefore repeatedly stressed the positive relationship between collaborative R&D and innovation performance. Collaboration, however, involves transaction costs...

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...

The literature on "Innovation Systems" is divided into several directories. Dif- ferences occur through the definition of the system's borders. This paper intro- duces a methodology how to differentiate between regional and technological effects of cooperative innovation activities and analyzes...

This paper explores the drivers of inter-firm R&D collaborations in a particular type of innovation network, the technological districts created in Italy under a specific public policy to promote innovation. The empirical analysis used an original database containing information on research...

A key issue of dfferent streams of economic literature is to determine the impact of certain dimensions of proximity on the cooperative behavior of actors and, thus, on interactive learning processes. This paper is a quantitative study on the impact of technological and geographical proximity on...

This paper examines empirically the role of market structure for the influence of spill-over effects on R&D-cooperations. The results of a microeconometric analysis, based on firm data on innovation, let in general presume that with intensified competition also the influence of spillovers on...

This paper examines empirically the theoretical relationship between spillover effects, in the sense of unintended knowledge transfer, and cooperations in research and development (R&D). According to the results of a logistic regression analysis which has been based on micro-level data, firms...
