We describe and compare the development trajectories of two German regions, South Saxony and Mecklenburg, with a special focus on entrepreneurship and innovation. South Saxony has a long history of self-employment and knowledge generation that results in a persistent culture of innovative...

We analyze the characteristics of new businesses in the German ICT industry, distinguishing them based on their choice between two IPR regimes: open source software (OSS) or closed source software (CSS). The share of new firms with an OSS-based business model has increased considerably over the...

The development of inventor networks is characterized by the addition of a significant number of new inventors, while a considerable number of incumbent inventors discontinue. We estimate the persistence of knowledge in regional inventor networks using alternative assumptions about knowledge...

From a macro perspective, inventor networks are characterized by rather stable structures. However, the high levels of fluidity of inventors and their ties found in reality contradicts this macro pattern. In order to explain these contradicting patterns, we zoom in on the intermediate group...

We investigate the stability of cooperative relationships between inventors and consequences for the characteristics and patent productivity of the respective regional innovation systems (RIS). The empirical analysis is for nine German regions over a period of 15 years. We find a rather high...

The emergence and solidification of network patterns is typically explained by the preferential attachment rule. The underlying logic is that a small number of actors which are characterized by an above average degree attract links at a higher rate than others. We raise the question as to what...

The paper reviews the approaches that have been followed for analyzing the effect of new business formation on regional development. It begins with an outline of how start-ups may affect regional development. In dealing with different ways of empirically assessing these effects, I particularly...

This paper reviews the current state of knowledge about the effect of new business formation on regional development. After a brief sketch of the origins of research on this issue, the main results of different lines of inquiry are discussed. Main issues are the development of start-up cohorts,...

This paper investigates the impact of new firms' quality on the magnitude of their employment effects. Our results clearly show that the quality of start-ups, measured by their affiliation with sectors and innovative industries, strongly influences the direct and the overall employment...
