Optimizing Distance-Based Methods for Big Data Analysis
Scholl, Tobias; Brenner, Thomas - Volkswirtschaft Abteilung, Fachbereich … - 2013
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...

The organizational and regional determinants of inter-regional collaborations – Academic inventors as bridging agents
Dornbusch, Friedrich; Proff, Sidonia von; Brenner, Thomas - Volkswirtschaft Abteilung, Fachbereich … - 2013
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...

Evolving localization patterns of company foundations - Evidence from the German MST-industry
Scholl, Tobias; Brenner, Thomas; Wendel, Martin - Volkswirtschaft Abteilung, Fachbereich … - 2012
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...

Universities, Public Research and Regional Innovation Output: An Empirical Study of 19 Technologies in Germany
Brenner, Thomas; Schlump, Charlotte - Volkswirtschaft Abteilung, Fachbereich … - 2013
It has been repeatedly shown that universities and public research institutes contribute to local innovation generation and facilitation. The mechanisms behind this contribution are well discussed in the literature. However, detailed empirical examinations are missing. We analyse the impact of...

Network Structures in Regional Innovation Systems
Stuck, Jérôme; Broekel, Tom; Revilla, Javier - Volkswirtschaft Abteilung, Fachbereich … - 2014
While interactive learning and inter-organisational relations are fundamental building blocks in RIS theory, the framework is rarely related to investigations of regional knowledge network structures, because in RIS literature relational structures and interaction networks are discussed in a...

Universities as local knowledge hubs under different technology regimes – New evidence from academic patenting
Dornbusch, Friedrich; Brenner, Thomas - Volkswirtschaft Abteilung, Fachbereich … - 2013
It is often claimed that universities act as local knowledge factories. Although this function is largely analyzed in previous research, there still is a knowledge gap regarding the role of a technological match between the profiles of partners in university-industry interactions. In addition,...

Benchmark Value Added Chains and Regional Clusters in German R&D Intensive Industries
Kosfeld, Reinhold; Titze, Mirko - Volkswirtschaft Abteilung, Fachbereich … - 2014
Although the phase of euphoria seems to be over, policymakers and regional agencies have maintained their interest in cluster policy. Modern cluster theory provides reasons for positive external effects that may accrue from interaction in a group of proximate enterprises operating in common and...

The effect of market access on the labor market: Evidence from German reunification
Zierahn, Ulrich - Volkswirtschaft Abteilung, Fachbereich … - 2012
The New Economic Geography predicts a positive effect of market access on wages, as represented by the wage equation …. Several studies provide empirical evidence in favor of the wage equation. However, a key problem is the endogeneity of market … access: it is challenging to identify the causal effects of market access on wages, since market access itself depends on …

Detecting Spatial Clustering Using a Firm-Level Index
Scholl, Tobias; Brenner, Thomas - Volkswirtschaft Abteilung, Fachbereich … - 2013
We present a new statistical method that detects industrial clusters at a firm level. The proposed method does not divide space into subunits whereby it is not affected by the Modifiable Areal Unit Problem (MAUP). Our metric differs both in its calculation and interpretation from existing...
