Die Rolle von Normen innerhalb des Innovationssystems ist sehr umstritten. Es wird sogar vermutet, dass die Zeit der Normung bereits abgelaufen sei. Andererseits wird von einer erstarrenden Regelsetzung gesprochen, die die notwendige Flexibilität für Erfindungen und Innovationen verhindere....

Impressive productivity performance during the last decades has weakened since 2007, reflecting the 2008-09 recession but also a poor performance in important sectors, like the information and communication technology sector. Reforms to raise long term productivity growth need to be pursued....

Technology standards such as the Wi-Fi or 5G mobile communication standard rely on standard-essential patents (SEPs). Increasing licensing revenues and several disputes between owners and users of SEPs raise the question about the patenting behavior of firms developing standardized technologies....

Why do so many high-priced acquisitions of entrepreneurial firms take place in network industries? We develop a theory of commercialization (entry or sale) in network industries showing that high equilibrium acquisition prices are driven by the incumbents' desire to prevent rivals from acquiring...

We estimate the determinants of various types of product innovation. Knowledge spillovers from rivals have a positive impact on incremental innovations. This impact is largely independent of the participation in R&D cooperations. Spillovers exert no such independent influence on drastic...

Often a quality improvement necessitates modifications of varietal product features. This paper studies firms' incentives to invest in quality improving R&D when this decision affects the goods' degree of varietal differention.

This paper contains an analysis of a quality ladders growth model with firm-level decreasing returns R&D technology. This analysis explains the relationship between competition in R&D races and firm R&D efforts. While competition proves to have a positive effect on industry growth rates, the...

In industries with network effects, incumbents’ installed bases create barriers to entry that discourage entrepreneurs from developing new innovations. Yet, entry is not the only commercialization route for entrepreneurs. We show that the option of selling to an incumbent increases innovation...
