The nexus between asylum seekers and defence spending in European NATO member states: a quantitative study of securitisation dynamics

This paper examines the relationship between the defence spending of European NATO members and their exposure to asylum seekers. While research shows that threat perceptions and domestic politics partly determine the defence spending of a state, the effect of migration has so far not been studied. This is remarkable because migration is increasingly framed as a security threat, also by NATO and European Union member states. Using a panel analysis, this paper explores the relationship between the defence spending of 23 European NATO members and the number of asylum seekers they register each year between 2000 and 2020. Results show a positive and significant relationship between the number of asylum seekers registered in a country and its overall military expenditure relative to GDP, equipment spending, and infrastructure spending. These findings shed new light on the origins of defence spending in collective security alliances, at a time when transatlantic burden sharing is at the centre of societal and academic debates.
