We study location choices and firm performance in the German machine tool industry, focusing on the forced migration of East German firms after World War II. Our analysis of location choices supports earlier findings that industry agglomerations attract further entrants. Relocating firms...

We investigate the lead-lag relationship between growth of patent applications, growth of R&D, and growth of total sectoral employment for 270 German labour market regions over the period 1999-2005. Our unique panel dataset includes information on four two-digit industries, namely Chemistry,...

Empirical analyses show that the employment effects of start-ups are highest in agglomerations, whereas moderately congested areas exhibit only modest effects, and weak or even no significant effects could be found in rural regions. This paper will set out to show that these discrepancies arise...
