Using patent citation data for the U.S., we test whether knowledge spillovers in biotechnology are sensitive to distance. Controlling for self-citation by inventor, assignee and examiner, cohort-based regression analysis shows that spillovers are local but that distance is becoming less...

This study aims at analyzing the differences in the factors that influence the probability of knowledge transfer within industry and from industry to science in the biotechnology sector. In order to model these knowledge flows a citation analysis on the basis of patent data was conducted and a...

Diese Arbeit trägt zu einem besseren Verständnis der Bedeutung von Kooperationen und Wissensaustausch für den Erfolg innovativer Unternehmen bei. Dabei gründet sie im Wesentlichen auf Josef Alois Schumpeters ‚Theorie der wirtschaftlichen Entwicklung‘ aus dem Jahre 1912. Neuere Theorien,...

In this paper the relationship between firm growth and external knowledge sources, such as related firms and universities, is studied.
