The emergence and evolution of a technology is intimately related to it's knowledge base. A knowledge base shows certain dynamics and evolves over time. Knowledge accumulation, especially the in-flow of knowledge from sources external to an industry, is crucial for the technology's knowledge...

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...

The concept of entrepreneurial ecosystems has been used as a framework to explain entrepreneurial activities within regions and industrial sectors. Despite the usefulness of this approach, the concept is under-theorized, especially with regard to the evolution of entrepreneurial ecosystems. The...

Innovation studies use labels such as radical or disruptive to qualify innovation according to different concepts. Within the literature, these labels are frequently used interchangeably due to overlaps in their characteristics. These various definitions present challenges when the labels are...

This paper analyzes whether firms conducting internal R&D and acquiring external high-tech equipment experience a complementarity effect. For German CIS data we conduct a complete set of indirect and direct complementarity tests refining the analysis by looking at various types of innovations...
