In recent years, modern economies have shifted away from being based on physical capital and towards being based on new knowledge (e.g., new ideas and inventions). Consequently, contemporary economic theorizing and key public policies have been based on the assumption that resources for...

There is mounting evidence demonstrating that entrepreneurship is spatially clustered and that these spatial differences are quite persistent over long periods of time. However, especially the sources of that persistence are not yet well-understood, and it is largely unclear whether persistent...

This Paper links the performance of new technology firms, measured in terms of growth, to geographic location. We introduce a model of firm growth that is specific to characteristics of the location as well as the firm and industry. The model is estimated using a new dataset identifying the...

In this paper we investigate the determinants of entrepreneurial activity in a cross section of German regions for the period 1998-2005. Departing from the knowledge spillover theory of entrepreneurship, the focus of our analysis is on the role of the regional environment and, in particular,...

Does regional unemployment increase or rather decrease entrepreneurial activity? Although this question has been hotly debated among researchers for decades the answers yielded so far are ambiguous and inconclusive. The paper proposes an innovative approach that takes not only interregional...

The literature focusing on the geography of entrepreneurship has developed some-thing of a schizophrenic approach. On the one hand is a series of studies, which have tried to identify characteristics specific to particular regions that account for inter-spatial variations in entrepreneurship. On...

This paper investigates the dynamic interrelationship between self-employment and unemployment rates. On the one hand, unemployment rates may stimulate start-up activity of self-employed. On the other hand, higher rates of self-employment may indicate increased entrepreneurial activity reducing...

This paper examines the link between liquidity constraints and investment behavior for German firms of different sizes from 1970 to 1986. Results indicate that medium sized firms appear to be more liquidity constrained in their investment behavior than either the smallest or largest firms in the...
