Extending variety seeking to multi-sided platforms: Impact of new retailer listing

摘要

This study uses theories of variety seeking to examine how a new retailer listing on a multi-sided platform (MSP) affects consumer buying behavior. Using a unique dataset from an online MSP, we evaluate changes in purchase frequency with individual retailers after a new one is listed. Contrary to expectations, the results indicate that consumers increase their purchase frequency at existing retailers. Moreover, compared to consistency seekers, variety-seeking consumers show a higher positive effect as they buy even more. This result is observed for retailers in both competing and non-competing product categories. Finally, we discuss the theoretical contributions and implications for MSPs and retailers.
