Entrepreneurial self-employment in Germany has undergone a strong upturn in the last 20 years. The number of self-employed people rose by 40 percent between 1991 and 2009. The reasons for this development are the catch-up processes in eastern Germany, structural change towards the service sector, and a strong willingness among the highly skilled, the unmarried and among foreigners to enter self-employment. ...

The analysis shows that high levels of regional self-employment and new business formation tend to be persistent for periods as long as 80 years and that such an entrepreneurial culture can even survive abrupt and drastic changes in the politic-economic ...

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 socialist regime significantly damaged this mechanism of an intergenerational transmission of entrepreneurial attitudes ...

A shortage of skilled labor and low female labor market participation are problems many developed countries have to face. Beside activating inactive women, one possible solution is to support the re-integration of unemployed women. Due to female-specific labor market constraints (preferences for exible working hours, discrimination), this is a difficult task, and the question arises whether active ...

Growth has been observed predominantly in companies in less research-intensive sectors and in small and medium-sized enterprises. Consequently, over the last decade, industrial ...
