Agglomeration of Knowledge : A Regional Economic Analysis for the German Economy

We investigate the effects of job-specific knowledge for individual labor earnings of workers in the German economy. The results indicate a positive effect for earnings stemming in particular from high-knowledge in the areas of sales and marketing, computers and electronics, mathematics, biology and law and government. Investigating the geographical concentration of employment reveals, for example, that workers with high-knowledge in the field of communication and media are concentrated in just a few places whereas workers with high-knowledge in law and government and administration and management are far more dispersed over the regions. These patterns of geographical localization of employment give evidence for differences in the dissemination of knowledge across peers and customers
