The paper at hand investigates how co-patenting over distance develops when aggregating inventive activities on a regional level. That means, the object of analysis is a link between two regions in contrast to other studies, where links between two individuals or firms are investigated. We...

This paper presents a firm and market model that is able to reproduce the empirically observed patterns on firm growth and its statistical characteristics. It goes beyond the existing firm models by reproducing all stylized facts established in the literature. Furthermore, the model is flexible...

The focus of this study is on integration processes in European R&D by analyzing the spatio-temporal dimension of three different R&D collaboration networks across Europe. These networks cover different types of knowledge creation, namely co-patent networks, project based R&D networks within the...

The question of why certain regions are more efficient in creating new knowledge is one of the main research issues in Regional Science. In the recent past, inter-regional knowledge networks ? defined as the inter-linkage of collaborative endeavours in knowledge creation across regional...

The mobility of university graduates is influenced by economic factors and individual attitudes. The paper at hand focuses on individual characteristics influencing the spatial preferences of graduates from three universities in Hesse (Germany). Using survey data from prospective graduates in...

Distance-based methods for measuring spatial concentration such as the Duranton-Overman index undergo an increasing popularity in the spatial econometrics community. However, a limiting factor for their usage is their computational complexity since both their memory requirements and running-time...

This paper examines regional effects of the InnoRegio program, which was conducted by the German Federal Ministry of Education and Research. The InnoRegio program has been a new tool of innovation policy with the aim to improve innovativeness in East Germany on the basis of prosperous regional...

Collaboration over distance is difficult to maintain in innovation projects which require a great deal of regional collaboration. However, patent documents reveal that a number of inventor teams are able to overcome long distances. Earlier literature started to investigate factors, which...

Cooperation in innovation processes has become crucial for the competitiveness of many firms. This paper focuses on technology-oriented East German firms and analyses details of their cooperation behaviour by studying the relationships between geographic and social proximity, the importance and...

We investigate company foundations in the German micro technology industry by means of a spatial-temporal micro-geographic analysis. In order to deal with our unusual detailed data, we develop a new distance-based framework for a logistic regression that is able to present results in a...
