Summary

Digital technologies are transforming marketing practices, bringing both opportunities and challenges. In this context, this thesis adopts a value co-creation perspective to examine how digital technologies can be effectively leveraged to generate customer value.

The dissertation presents four key findings.

First, it identifies that customer value enabled by digital technologies is multidimensional, encompassing both cognitive (functional, economic) and affective (eBilde av Yaozhi_Zhangmotional, experiential) dimensions.

Second, it shows that such multidimensional value can be co-created through customer interactions with various actors within a broader value ecosystem, including both human participants and emerging digital entities such as generative AI.

Third, it reveals that enhancing the operant resources of value co-creators, particularly their credibility traits, can significantly foster customer value co-creation behaviors.

Finally, it demonstrates that socio-psychological dynamics, including processing fluency and social presence, can moderate the process of value co-creation mediated by digital technologies and therefore warrant careful management.

Overall, this thesis provides critical validation, extension, and refinement of existing theories on value co-creation in the digital marketing context. Practically, it offers actionable insights for digital marketers on how emerging technologies can be strategically applied to foster more meaningful and effective customer value creation.
