The last decades saw a pronounced shift in innovation policy in Germany and many other countries towards increased funding of cooperative R&D. Over the last years, competitions between regional initiatives pushed this trend even further by adding a regional perspective, by increasing the scope...

Being a "jack-of-all-trades" increases the probability of running an entrepreneurial venture successfully; but what happens to "jack-of-few-trades" who lack sufficient skills? This paper investigates a possible compensation mechanism between balanced skills and cities, and how this compensatory...

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 role of geographical proximity in fostering connections and knowledge flows between innovative actors ranks among the most controversial themes in the research of innovation systems, regional networks and new economic geography. While there is ample empirical evidence on the constituent...

What characterizes regions where right-wing populist parties are relatively successful? A prominent hypothesis proposed in recent literature claims that places that are "left behind" or "do not matter" are a breeding ground for the rise of populism. We re-examine this hypothesis by analyzing the...

Previous research on market economies characterized by stable framework conditions shows that several regional factors determine start-up activity. Not much is known about what drives entrepreneurship in unstable environments characterized by significant institutional changes that affect the...

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 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...
