This paper studies the frequency of observing a certain number of firms or employees in a region for a given industry. Various predictions for these frequencies are deduced from theoretical considerations. Then, the empirical distributions of 198 industries in Germany are analysed. It is found...

A stochastic model of the evolution of the firm population in a region and industry is developed. This model is used to make predictions about the expected probability distribution of the firm number in regions and their dynamics. Data on the spatial distribution of firms in Germany is used to...

The paper investigates the contribution of cooperative and non-cooperative R&D subsidies to firm growth. Of particular interest is hereby firms' embeddedness into subsidized cooperation networks. For the empirical analysis we utilize an unbalanced panel of 2.199 German manufacturing firms...
