Long-term associative issue ownership change: a panel study in Belgium

Issue ownership has gained a prominent position as one of the key theories to understand how voter’s issue perceptions affect their electoral behavior. Yet, whereas the original theory assumed that party reputations were relatively stable, various studies have shown that issue ownership perceptions fluctuate over time. Despite the growing evidence that ownership perceptions are dynamic, we know surprisingly little about the determinants of change, especially at the individual level. This paper develops an individual-level framework to understand how issue ownership perceptions change over time, arguing that mediated party communication is a key driver of change. It also incorporates individual features of voters, most notably their political predispositions – as determinants of changing issue ownership perceptions. We test our model on unique longitudinal panel data from Belgium, spanning a five-year period. The results suggest that party communications, government participation, party size and voter’s party preferences determine changes in ownership perceptions.
