• Abstract: This paper develops a theoretical framework to analyze live streaming platforms as two-sided markets connecting streamers and viewers, focusing on the "head effect" where a few top streamers attract most viewers due to strong network effects and platform policies like commission rates and traffic allocation algorithms. Using static and dynamic models, it examines how these factors lead to traffic concentration and winner-takes-all scenarios. The welfare implications are assessed, revealing that while such concentration may enhance consumer utility short-term, it can reduce content diversity and overall social welfare in the long run. The paper proposes policy interventions to adjust traffic allocation, promoting a more equitable distribution of viewers across streamers, and demonstrates through simulations that combining multiple policies can significantly reduce market concentration and enhance social welfare
