Regional related and unrelated variety and the innovative performance of European NUTS-2 regions

This Master thesis presents a scientific replication of Castaldi, Frenken and Los (2015). The hypotheses that related variety is positively associated with innovative output, and that unrelated variety is positively associated with breakthrough innovations are confirmed using data on European NUTS-2 regions. Furthermore, the thesis adds to the related-unrelated variety literature by explicitly considering the difference between technological and industrial variety.
