This research explores the antecedents and consequences of brand passion. Consumer–brand relationship constructs (brand identification and brand trust) may influence consumers' passion for a brand. Brand passion in turn may influence brand commitment, willingness to pay a higher price for the brand, and positive word of mouth. A partial least squares structural equation model applied to data collected from a representative sample of 1505 study participants demonstrates that brand passion depends on brand identification and brand trust. Consumer's passion for a brand has great managerial relevance and a direct effect on word of mouth and commitment, as well as an indirect effect on willingness to pay a higher price, as mediated by commitment.
