The increasing globalization of higher education has sparked debates about the impact of international student presence on natives. This paper provides the first evidence on the impact of exposure to international students on the long-term outcomes of native students. I combine unique survey and administrative data from the Netherlands covering one million students across three decades. My identification strategy relies on idiosyncratic variation in the share of international students within university programs over time. I find that exposure to international students leads native students to (i) form more social ties with non-natives, (ii) hold more positive attitudes towards migration and learning about other cultures, and (iii) seek opportunities abroad. I find precisely estimated zero labor market effects for native students up to 25 years after university entry. These findings suggest that exposure to international students makes natives more culturally open and internationally oriented, without compromising their local economic success.
Hydrogen is expected to play an important role in the transition towards a sustainable energy system. The North Sea, one of the world's most active regions for offshore wind development, presents a unique opportunity to establish large-scale production of “green” hydrogen, for which the EU and Dutch government have set ambitious targets. However, the economic feasibility of such ideas is largely unknown. In this research we use simulation, in combination with machine learning and optimization, to offer insights into the conditions under which large-scale offshore wind-based hydrogen production can be technically and economically viable.
