User Agents Drive New Platform Competition in Recommendation Markets

This research explores "agentic recommendation markets" where user agents specify needs before choosing a platform, forcing platforms to compete for attention. It finds that while user-centric recommendation expands options, platforms engage in strategic, selectively positive explanations, which user agents can mitigate by linking platform actions to user feedback.
