We apply the property rights theory of Grossman-Hart-Moore in the music industry and study the optimal allocation of copyright between the artists who create music and the labels who promote and distribute it. Digital technology opens up a role for new intermediaries. We find that entry of...

The positive effect of public research on industrial innovations is beyond controversy: public research institutions produce knowledge that is subsequently transferred into product and process innovations by private businesses. Besides this rather passive role in commercializing inventions,...

The transfer of knowledge and technology from academia to industry is usually understood as a process. While previous research focuses on phenomena along the process and its outcomes, the starting point of the process - the initiation of a transfer activity - remains unstudied. We provide first...

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...

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...

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...

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...

The aim of this paper is to analyse the effects of knowledge management on the innovation success of firms in Germany. Using a matching procedure on data from the German Innovation Survey of 2003 (“Mannheim Innovation Panel”), we pair firms applying knowledge management with twin firms with...

This paper proposes a search strategy for photovoltaic patents which allows to distinguish the photovoltaic system into sub-trajectories. Identifying and analyzing sub-trajectories is of particular importance for understanding micro patterns of technological change. The proposed search strategy...

We examine ownership patterns of German university-invented patents before and after the abolition of the "professors' privilege" in 2002 to explore how the legal change affected patenting activities. Our data show a shift from individually-owned and firm-owned patents to university-owned...
