Category Kings and Commoners: Within and Cross-Category SpillOvers in the Sharing Economy

This chapter focuses on the largely unexplored within- and cross-category spillovers between category kings and commoners within the field of the sharing economy. Going beyond the reputational spill-overs that are the main focus of extant literature, the authors also consider spill-overs in awareness, regulation, and customer usage between category kings and commoners, providing a holistic view of what it means to be a commoner in the same or adjacent category as a king. On the basis of a mixed-method study based on semi-structured interviews with UK sharing platforms and a consumer survey, the authors show that category commoners are affected by kings differently depending whether they are in the exact same sub-category or in an adjacent one within the same larger category. This chapter expands extant work on within and cross-category dynamics by taking the less popular perspective of the less visible category members. Studying these dynamics in the setting of the sharing economy also contributes to the authors’ knowledge of what enables/hinders the growth of a new field as a whole. Finally, the findings have important policy implications.
