Résumé
The Covid-19 pandemic has spurred a discussion about the role of the European Union (EU) in the governance of cross-border health threats. Antimicrobial resistance (AMR) is another major global health challenge that requires international collective action to be resolved. By using survey data from experts on AMR from 29 European countries, this paper investigates the support for an increase in the power of EU over AMR. Based on insights from collective action theory, we hypothesize that experts who believe that other countries free ride, will be more supportive of EU as a Leviathan in the European response to AMR. The results show that the experts generally were strongly in favor of expanding the authority of the EU over AMR. Furthermore, in line with theoretical expectations, experts who think that other countries free ride, are particularly supportive of more EU power over AMR.
