Résumé de la thèse The aim of my PhD dissertation is to provide an in-depth understanding of the determinants and effects of short-term dynamics in issue ownership (IO). Issue Ownership is the link between parties, voters, and issues. More specifically, it is voters’ perceptions of party competence to deal with certain issues. While IO was initially considered as a stable phenomenon explaining election outcomes, recent studies show that citizens can change their competence attributions in the short term. Nevertheless, little is yet known about the sources and the consequences of such dynamics. The goal of my thesis is to provide theoretical and empirical explanations to this phenomenon. The first paper of my thesis will concern the origins of IO perception dynamics. It will stress the role of parties’ direct and indirect communication on the instability of IO perceptions. Although there is growing evidence on the origins of IO dynamics, evidence on its effects remains scarce. Accordingly, the second paper will tackle the consequences of IO perceptions on electoral choice formation. The third paper will posit IO instability as a determinant of electoral volatility, in addition to classic sources of party switching. Finally, the fourth paper will tackle the origins and consequences of IO dynamics in a unified way. Thus, my PhD dissertation will offer a comprehensive view of the short-term dynamics in IO perceptions and party preferences within a real campaign setting. For that purpose, I use panel data, media data, and ads data collected during the 2015 Swiss National Elections. My thesis has scientific, political, and practical implications.
