We analyze the development of the German knowledge base measured by co-classifications of patents by German inventors and relate this technological development to changes in the structure of the underlying inventor networks. Our central hypothesis states that technologies which become more...

We explore if the Knowledge Spillover Theory of Entrepreneurship, applied to FDI, provides at least a partial explanation for the greater emergence of recent knowledge-based entrepreneurship in Ireland compared with Wales. In order to examine how FDI and entrepreneurship policy in these two...

Various forms of interaction during the process of research and innovation constitute a global network of knowledge generation and diffusion. Countries and their research organizations and individual scientists need to be embedded in this network to participate in global knowledge ows and to...

Cluster policies aim at improving collaboration between co-located actors to address systemic failures. As yet, cluster policy evaluations are mainly concerned with effects on firm performance. Some recent studies move to the system level by assessing how the structure of actor-based knowledge...

The concept of Bridging Technologies (BTs) refers to technologies which are important for the regional knowledge base by connecting different fields and thereby enabling technological development. We provide analytical tools to identify BTs and study their evolution over time. We apply these...

The knowledge spillover theory of entrepreneurship predicts that entrepreneurial activity is greater in regions with more knowledge conditional on the commercialization efficiency of incumbents, which limits entrepreneurial discovery. We extend the theory to contend that localized competition...

Acs, Audretsch, Braunerhjelm, and Carlsson (2003) propose a new growth theory model featuring a geographically constrained spillover mechanism provided by new ventures and incumbent firms that convert a region’s stock of knowledge into economically useful, firm-specific knowledge. This implies...
