The mobility of workers is one of the most important channels through which knowledge is transferred across geographical and organizational boundaries. This mechanism is partic-ularly important in early stages of knowledge production, where knowledge is not yet fully codiﬁed and still requires insights of the knowledge producers themselves to apply it to a commercial use. This thesis therefore investigates the eﬀects of the mobility of two types of highly skilled workers on the rate and direction of innovation and research.
The ﬁrst paper investigates the ﬁrm level consequences. It asks how hiring foreign R&D workers eﬀects the type of ﬁrm level innovation. By diﬀerentiating between explorative and exploitative innovation, it ﬁnds that hiring foreign R&D workers is strongly associated with exploration, and therefore can shift a ﬁrm’s inventive activities towards new technology ﬁelds. These eﬀects hold, even after controlling for diﬀerences in education between newly hired foreign workers and incumbent workers, and are most pronounced when foreign workers are from countries that are new to the ﬁrm.
The second paper investigates the individual level consequences of international mobility in the context of academic entrepreneurship. While in this context, international mobility is commonly linked to higher levels of scientiﬁc productivity, little remains known about its eﬀects on other aspects of academics’ careers, such as academic entrepreneurship. By diﬀerentiating between diﬀerent types of international mobility, the paper ﬁnds that inter-nationally mobile native academics were more likely to start a company, whereas immigrant academics are about 38-47% less likely to start a company in Denmark compared to re-turnees. This diﬀerence suggests that there are substantial barriers to foreign academics’ engagement in academic entrepreneurship.
The ﬁnal paper investigates how academic entrepreneurship aﬀects scientiﬁc knowledge production. Spanning the boundary between the academic and commercial sector, not only requires academic entrepreneurs to fulﬁl multiple roles at the same time, but also leads to the accumulation of skills and knowledge, likely to have long-term eﬀects. This paper, therefore focusses on two important outcomes – scientiﬁc productivity and collaboration, and investigates the immediate and long term eﬀects of academic entrepreneurship. It ﬁnds, that academic entrepreneurship is associated to an immediate drop in scientiﬁc productivity, which persists immediately after the entrepreneurial spell, but attenuates in the long run. It further establishes a negative eﬀect on repeated co-authorships, persisting in the long run. It therefore draws attention to potentially negative career eﬀects academic entrepreneurs face when commercializing their research.
