This paper discusses how the results of simulation models can be made more reliable and the method of simulating therefore more widely applicable. We suggested to calibrate simulation models empirically and developed a methodology based on Critical Realism in order to so. We suggested combining...

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...

This paper investigates whether the economic factors that are related to firm growth in the literature also determine the development path of firms. This means that we test which economic factors possess the ability to remain effective for a longer period of time. We examine three variables:...

This paper examines the time structure of the effects of R&D activities on firm growth. The main questions are whether R&D activities come together with firms' growth in the subsequent periods and how this relationship depends on other characteristics of the firms, such as size and industry. In...

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...

In this paper the relationship between firm growth and external knowledge sources, such as related firms and universities, is studied. The spatial characteristics of these relationships are examined by geolocating firms into a more realistic relational space using travel time distances and using...

Academic inventions have to be transferred to industry to become an innovation. Scientists face multiple options for this transfer, from informal knowledge transfers to patents, licences, and spin-offs. These transfer channels require different efforts and inhibit different degrees of...

Measuring the innovation performance of regions or nations has been repeatedly done in the literature. What is missing in the literature is a discussion of what innovation performance of a region means. How do regions or nations contribute really to the innovation output of firms? And how...
