PurposeIn the modern era, brand authenticity is one of the most powerful positioning strategies for sustainable business growth. This study investigated the impacts of perceived brand authenticity dimensions (i.e., quality commitment, heritage, sincerity) on brand love to predict Generation Y's behavior from the Asian context.Design/methodology/approachThis is new empirical research that tested the proposed hypotheses through PLS-SEM, as PLS is the most robust technique for predicting consumer behavior. Importantly, consumers (of Generation Y) from five Asian countries contributed to this study, and data collected from 427 Asian millennials on global brands.FindingsThe results analysis revealed that perceived brand authenticity dimensions significantly impacted brand love, which positively affected Asian millennials' behavioral outcomes (i.e., continuous purchase intention and price premium).Research limitations/implicationsThis study investigated dimensions of perceived brand authenticity to predict Asian millennials' behavioral outcomes in a broader perspective. Future researchers may investigate a specific culture with a larger sample size to predict millennials behavior.Practical implicationsThis study has several implications that guide the global managers of several service and manufacturing industries to develop various positioning and relationship strategies for global brands to target Asian markets effectively.Originality/valueUsing attribution theory, this is the first novel research study that empirically discussed the dimensions of perceived brand authenticity, brand love, and Asian millennials' behavior toward global brands.
