题目：Product Quality, Search, and Competition in Digital Markets

摘要：

This seminar explores how uncertainty in product quality influences consumer search behavior and competition in digital markets. I focus on three key areas of recent research: (i) the role of platforms in shaping online advertising and search dynamics, (ii) the welfare effects of market entry, and (iii) the impact of quality observability amidst search frictions. I will examine the growing influence of platforms on consumer decisions under quality uncertainty, despite the low search costs in digital environments. I will also discuss why reducing search or entry costs can yield unexpected outcomes for competition and market performance.
