Customer engagement marketing-defined as a firm's deliberate effort to motivate, empower, and measure customer contributions to marketing functions-marks a shift in marketing research and business practice. After defining and differentiating engagement marketing, the authors present a typology of its two primary forms and offer tenets that link specific strategic elements to customer outcomes and thereby firm performance, theorizing that the effectiveness of engagement marketing arises from the establishment of psychological ownership and self-transformation. The authors provide evidence in support of the derived tenets through case illustrations, as well as a quasi-experimental field test of the central tenet of engagement marketing.

Creating effective online customer experiences through well-designed product web pages is critical to success in online retailing. How such web pages should look specifically, however, remains unclear. Previous work has only addressed a few online design elements in isolation, without accounting for the potential need to adjust experiences to reflect the characteristics of the products or brands being sold. Across 16 experiments, this research investigates how 13 unique design elements shape four dimensions of the online customer experience (informativeness, entertainment, social presence, and sensory appeal) and thus influence purchase. Product (search vs. experience) and brand (trustworthiness) characteristics exacerbate or mitigate the uncertainty inherent in online shopping, such that they moderate the influence of each experience dimension on purchases. A field experiment that manipulates real product pages on Amazon.com affirms these findings. The results thus provide managers with clear strategic guidance on how to build effective web pages.

Exchange events are fundamental building blocks of business relationships and essential to relationship development. However, some events contribute to incremental relationship development, as predicted by life cycle theories, whereas others spark "turning points" with dramatic impacts on the relationship. Such transformational relationship events are encounters between exchange partners that significantly disconfirm relational expectations (positively or negatively); they result in dramatic, discontinuous change to the relationship's trajectory and often reformulate the relationship itself. With a three-study, multimethod design, the authors (1) establish a foundation for differentiating dramatic and incremental exchange events on the basis of relational versus product expectations and disconfirmations, thus revealing that strong relationships benefit product disconfirmations but harm relational disconfirmations, and (2) conceptualize, define, and differentiate transformational relationship events from other types of disconfirming events and then link them to exchange performance.

Group marketing uses the psychological mechanisms underlying group influence to drive customer behaviors that are beneficial to the firm. It is predicated on the firm's ability to guide two necessary and sufficient conditions: (1) a customer's awareness of an affiliation with the focal group and (2) exposure to group norms. By examining what it means to be affiliated with a group; determining how group norms are inferred, applied, and maintained; and testing a wide variety of ways in which these conditions become manifest, this research demonstrates the theoretical foundations of group marketing. Groups influence purchase behaviors by altering information and identity appraisals during decision making. Time in a purchase domain emerges as a critical determinant of the strength of group influence. Although previous research has suggested that social influence diminishes over time, a longitudinal field study and an experiment reveal that this prediction holds only when information appraisal dominates; an opposite effect arises when identity appraisal dominates. Group efficacy strengthens, but product price weakens, the effects of groups on purchase behaviors.
