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 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...

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...

This paper presents a History Friendly Model which addresses the issue of the bifurcation in technological styles" between US and Britain during the nineteenth century. The model aims at gaining a better understanding of the micro-dynamics that gave rise to different patterns of innovation in...

This paper takes a different perspective toward the escape entry incentive of incumbent firms to innovate. New entrants spawned from incumbents are not necessarily a threat; they can complement incumbents' production by commercializing knowledge incumbents are not willing or able to exploit....

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...

We develop a model in which stronger protection of intellectual property rights has an inverted U-shaped effect on innovation. Intellectual property rights protection allows the incumbent firms to capture part of the rents of commercial exploration that would otherwise accrue to the...

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...
