Using a new dataset encompassing more than 2,200 inventions made by Max Planck Society researchers from 1980 to 2004, we explore how licensee and technology characteristics affect the licensing and commercialization of technologies from public research. We find no evidence that spin-offs and...

Necessity spin-offs are organized by employees of incumbent firms to escape deteriorating job conditions. This paper proposes a conceptual model of the spin-off process. Necessity spin-offs are distinguished from opportunity spin-offs on the basis of their triggering events. An empirical...

Entry into an industry often clusters in regions where the industry is already concentrated, which is suggestive of agglomeration economies. Regional public research activities may exert another attracting force on entrants into science-based industries. Empirically these proximity effects are...

In this paper the relationship between firm growth and external knowledge sources, such as related firms and universities, is studied. The spatial characteristics of these relationships are examined by geolocating firms into a more realistic relational space using travel time distances and using...

This paper studies the industry-specific relationship between industrial clustering and firm growth. Micro-geographically defined agglomeration measures, free of the modifiable areal unit problem (MAUP), are used to study 23 industries. The spatial impacts of agglomeration of related economic...

This paper studies 40 years of evolution in the German laser industry to test the generality of evolutionary patterns observed in the U.S. laser industry. Key characteristics found in the U.S. industry are also present in Germany. There is sustained entry into the industry, and neither a...
