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...

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...

A new model of economic growth introduces the knowledge filter between new generic knowledge and economically-useful knowledge. It identifies both the formation of new ventures and the absorptive capacity of incumbent firms as the mechanisms that penetrate the knowledge filter. Recent empirical...

A new model of economic growth introduces the knowledge filter between new knowledge and economically useful knowledge. It identifies both new ventures and incumbent firms as the mechanisms that penetrate the knowledge filter. Recent empirical work has shown that new firms are more proficient at...

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...
