We compare two leading regional innovation systems (RIS) in East Germany with two RIS in West Germany of about the same size and internal settlement structure. Our analyses show that differences in the performance between the regions cannot easily be related to the structural properties of 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...

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...

Drawing on representative household data from the German Socio-Economic Panel, we examine the role of an early precursor of entrepreneurial development - parental role models - for the individual decision to become self-employed in the post-unified Germany. The findings suggest that the...

Often, a person will become an entrepreneur only after a period of dependent employment, suggesting that occupational choices precede entrepreneurial choices. We investigate the relationship between occupational choice and self-employment. The findings suggest that the occupational choice of...

This paper investigates the geography and the effect of people in creative oc-cupation in Germany. The population share of the Creative Class as well as of bohemians and artists is relatively high in larger cities, but smaller places and rural regions may also have a considerable proportion of...

We assess the efficiency of regional innovation systems (RIS) in Germany by means of a knowledge production function. This function relates private sector research and development (R&D) activity in a region to the number of inventions that have been registered by residents of that region....
