The international mobility of research staff facilitates this global reach, as both professors and graduate students are generally highly mobile in their careers and can organise long-term visiting periods in other institutions. Multinationals are very strategic in their location decisions, particularly for tapping into a knowledge-intensive region elsewhere in the world. The same is not always true for many SMEs that lack the same capacity or benefit from a global partner search as a large multinational. This positive influence is evident to a lesser degree for cross-border traders, which could signify benefits to businesses of accessing diverse knowledge inputs at the cross-border level.
