What Explains Increasing Euroscepticism in Switzerland? A Longitudinal Analysis

Since just over half of the Swiss voters decided not to join the European Economic Area in 1992, public opinion on the European Union (EU) has consistently become more critical in Switzerland. While macro factors such as the 2008 economic crisis undoubtedly played a role, examining changes within individuals sheds light on why Swiss citizens changed their mind at some point in their life course. Based on previous literature, we predict that both economic and political factors play a role in shaping Swiss citizens’ (un)willingness to join the EU. In contrast to most studies that compare attitudes between individuals, we go a step further and examine how changes within individuals affect changes in attitudes toward the EU. Our analyses of SHP data (1999–2014) show that, in line with previous studies, citizens with a higher social status (e.g., higher education) are more likely to support joining the EU while those holding right-wing values are less likely to do so. When analysing changes within individuals however, we find that above all, changes in political attitudes (e.g., increasingly right-wing, less interest in politics) result in less support for Switzerland joining the EU.
