Despite their generally increasing use, the adoption of mobile shopping applications often differs across purchase contexts. In order to advance our understanding of smartphonebased mobile shopping acceptance, this study integrates and extends existing approaches from technology acceptance literature by examining two previously underexplored aspects. Firstly, the study examines the impact of different mobile and personal benefits (instant connectivity, contextual value and hedonic motivation), customer characteristics (habit) and risk facets (financial, performance, and security risk) as antecedents of mobile shopping acceptance. Secondly, it is assumed that several acceptance drivers differ in relevance subject to the perception of three mobile shopping characteristics (location sensitivity, time criticality, and extent of control), while other drivers are assumed to matter independent of the context. Based on a dataset of 410 smartphone shoppers, empirical results demonstrate that several acceptance predictors are associated with ease of use and usefulness, which in turn affect intentional and behavioral outcomes. Furthermore, the extent to which risks and benefits impact ease of use and usefulness is influenced by the three contextual characteristics. From a managerial perspective, results show which factors to consider in the development of mobile shopping applications and in which different application contexts they matter.

Sponsoring joins brands with sports, the arts, and events in mutually beneficial partnerships. In the context of sports, the authors examine how sponsorship deal characteristics affect consumer inferences, attitudes, and behavioral intentions toward a sponsor and a sport property in a partnership. The authors develop a conceptual framework that links a holistic set of sponsorship deal characteristics (i.e., contract length, regional proximity of the sponsor, sponsorship fee, and sponsorship type) to individual consumer perceptions. Study 1 tests the framework in a field study of 2,787 consumers across 44 different sponsorships. Study 2 largely confirms the findings of the field study in an experimental field study. Overall, the results show that regionally proximate and long-term partnerships benefit as consumers make positive inferences about partnership fit and sponsor motives. In contrast, consumers associate high sponsorship fees, international sponsors, and naming-rights relationships with calculative motives and perceive these factors negatively. For managers, finding that sponsorship deal characteristics matter is important, not only for sponsor-property relationships but also for relationships between the sponsoring brands and consumers.

The use of brand extensions has become fundamental to the business model of most luxury brands. Many traditional luxury brands such as Louis Vuitton or Chanel have expanded into traditional luxury sectors beyond their core business. Some brands such as Armani or Prada even crossed boundaries to nontraditional lifestyle segments to pursue new business opportunities. Given the high practical relevance of brand extensions for luxury brands and the importance to understand the success factors for their extendibility and potential backward effects on the parent brand, surprisingly little research has addressed these issues for luxury brands in comparison to nonluxury brands. The current research reveals extension‐related differences between luxury and nonluxury brands by simultaneously analyzing key dimensions of parent brand value, fit, and extension category involvement on the consumer's attitude toward the brand extension, which in turn influences the postextension image of the parent brand. Results of a structural equation model based on a survey among 492 participants show that the predominant driver of brand extension success for both luxury and nonluxury brands is overall extension fit, followed by the consumer's involvement in the extension category. The influence of functional value of the parent brand on the extension evaluation is more important for nonluxury brands. The hedonic value of the parent brand is found to be of relevance only in case of luxury brands. Moreover, a reciprocal spillover effect between the extension evaluation and the parent brand evaluation is observed. The degree of luxuriousness of the parent brand moderates this relationship. This effect is weaker for luxury brands.
