This study explores how brand credibility and brand prestige affect brand purchase intention and empirically investigates how the combinatory mechanism of brand credibility and brand prestige materialize across multiple product categories. The proposed model of six latent constructs is tested with structural equation modeling analysis: brand credibility, brand prestige, perceived quality, information costs saved, perceived risk, and brand purchase intention. The results suggest that both brand credibility and brand prestige positively influence brand purchase intention through perceived quality, information costs saved, and perceived risk under different product categories representing the high and low self-expressive nature. Several implications for advertising messages and brand positioning strategies are discussed.

Purpose The purpose of this study is to investigate user perceptions of mobile app characteristics and interrelationships among identified mobile app characteristics, perceived benefits and post-adoption behaviors. Design/methodology/approach Using a self-administered online survey (n = 503) drawn from a consumer panel of US smartphone users, this study tests the proposed model that explains why stickiness and word of mouth (WOM) are enhanced during the post-adoption stage. Findings The results indicate that user perceptions of mobile app characteristics, perceived ubiquity, perceived informativeness and perceived personalization are positively associated with mobile app usefulness, thereby leading to increased stickiness and positive WOM intentions. Furthermore, perceived personalization is found to become the strongest predictor of usefulness and playful engagement with the mobile app. Research limitations/implications The findings are derived from a one-shot correlational study. There is no guarantee that the proposed model establishes causal directions among the latent constructs. Therefore, future research should test the conceptual model in an experimental setting by manipulating the degree and types of ubiquity, informativeness and personalization. Practical implications The findings of this research provide managerial guidelines for developing effective mobile app strategies involving utilitarian and hedonic benefits, thereby enhancing user stickiness and WOM intentions. Originality/value This paper is the first attempt to develop a conceptual framework that integrates user perceptions of mobile app characteristics into the underlying process of post-adoption behaviors. It empirically demonstrates the importance of ubiquity, informativeness and personalization in building and sustaining loyal relationships with mobile app users.
