Introducing Keyword Recommender System (KRS): A Noble Alternative Search Recommender System in the Age of AI

Hybrid Event

50 N Harvard St., Cotting Hall, Room 107
In this talk, we explore the Keyword Recommender System (KRS) and consider its impact on sales volumes and market concentration. Unlike traditional, item-level recommenders, KRSs facilitate search query formation with potentially positive or negative consequences for search costs, resultant product fit, transaction volumes, and consumption diversity. We explore these effects via a randomized field experiment conducted with one of the largest mobile food-delivery platforms in Asia. The results of this experiment show that providing consumers with access to a KRS leads to a 1.2% rise in purchases over a 30-day period. Furthermore, access to a KRS leads to increased sales diversity, at both the individual and market levels.
