In this paper, we analyze the problem of congestion and quality loss of data transmission through the Internet from an economic perspective. We show that due to the congestion problem, quality sensitive services are likely to be crowded out by high volume but less quality sensitive applications...

This paper investigates the causes of the shortfall in private R&D expenditure of the EU compared to the US. It shows that differences in the structure of the two economies play only a minor role in explaining the R&D gap. Instead, the European R&D shortfall is mainly caused by a negative...

Cluster studies have shown that innovation can be understood as the result of an inter- organizational process, where a division of labor with regard to exploration and exploitation exists among the actors inside the cluster. A cluster is ambidextrous if it manages to balance innovative...

Meta-regression models are increasingly utilized to integrate empirical results across studies while controlling for the potential threats of data-mining and publication bias. We propose extended meta-regression models and evaluate their performance in identifying genuine empirical effects by...

We apply the accelerator principle to measure the functional efficiency of capital markets. We estimate the elasticity of capital with respect to output using a panel of firms across 44 countries, and compare the results with existing approaches. Furthermore, we correlate our measure with...

The last decades saw a pronounced shift in innovation policy in Germany and many other countries towards increased funding of cooperative R&D. Over the last years, competitions between regional initiatives pushed this trend even further by adding a regional perspective, by increasing the scope...
