Fighting Euroscepticism: The Impact of EU Institutional Campaigns on Support for European Integration

Co-authored with Roberto Pannico

Utilitarian theories propose that citizens’ support for the EU is based on an instrumental calculus about the costs and benefits of European integration. Drawing on these theories, we analyze whether and how ads produced by European institutions can reduce Euroscepticism. Our findings, based on a panel survey experiment fielded in Spain, indicate that these ads increase support for the EU, and that ads emphasizing the policy benefits of European integration are more effective than ads emphasizing its reduced costs. However, these positive effects are short-lived, since they had disappeared one year after citizens were initially exposed to the ads. In a context of growing Euroscepticism, these findings, based on realistic treatments administered in a realistic environment, have relevant theoretical and policy implications.
