This paper empirically studies the impact of the adoption of open source software (OSS) on firms' labor productivity and innovative behavior. Using a representative sample of German firms, the results show that the adoption of OSS operating systems for servers and general OSS applications has no...

We develop a model of R&D competition between an incumbent and a potential entrant with network externalities and durable goods. We show that the threat of entry eliminates the commitment problem that an incumbent may face in its R&D decision due to the goods? durability. Moreover, a potential...

This paper analyzes the impact of network externalities on R&D competition between an incumbent and a potential entrant. The analysis shows that the incumbent always invests more than the entrant in the development of higher quality network goods. However, the incumbent exhibits a too low level...

This paper studies the incentives to undertake uncertain R&D initiatives in a dynamic duopoly network industry. It is shown that network externalities positively affect the incentives to invest in R&D. In the model, competition resembles a preemption race and, therefore, market performance...

The knowledge produced by academic scientists has been identified as a potential key driver of technological progress. Recent policies in Europe aim at increasing commercially orientated activities in academe. Based on a sample of German scientists across all fields of science we investigate the...

While often presumed in academic literature and policy discussions there is little empirical evidence showing that academic patents protect more basic inventions than corporate patents. This study provides new evidence on the basicness of academic patents using German professor patents linked to...

Against the background of the so-called European paradox, i.e. the conjecture that EU countries lack the capability to transfer science into commercial innovations, knowledge transfer from academia to industry has been a central issue in policy debates recently. Based on a sample of German...
