Why Does the Effect of New Business Formation Differ Across Regions?

We investigate regional differences in the effect of new business formation on employment growth in West Germany. We find an inverse U-shaped relationship between the level of start-up activity and employment change. The main variables that shape the employment effects of new businesses in a region are population density, the share of medium-skilled workers, the amount of innovation activities as measured by the proportion of research and development (R&D) employees, and an entrepreneurial character of the regional technological regime. In contrast, a high share of small-business employment has a negative influence on the employment effect of start-ups. Other indicators for education, innovation activity, and labor productivity do not prove to be statistically significant.
