Sailing with Artificial Intelligence: Recommendation systems and digital markets

In this complex digital age, people’s lives are greatly simplified by recommendation systems – AI algorithms that make it easier for online users to find the things they like in a vast ocean of options. These systems have profound impacts on individuals’ decisions and market outcomes. On one hand, they provide a higher match value than when individuals autonomously engage in a costly search for their preferred items. On the other hand, they lead to substantial market concentration and prompt sellers to raise their prices. Although our research generally indicates a positive net effect, the complex influence of these AI tools on economic outcomes requires careful examination and understanding.
