人文社会科学名家讲坛第432讲暨商学院双周高端seminar第19讲： Product Quality, Search, and Competition in Digital Markets 主讲人： 陈勇民（Yongmin Chen） 时间: 2024年10月23日（周三）下午15:00 地点：商学院 214室 承办单位：商学院 内容简介 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. 主讲人简介 陈勇民（Yongmin Chen）是美国科罗拉多大学（University of Colorado Boulder）经济学终身教授和Provost讲席教授。他是一位专长于产业组织学（产业经济学）的著名经济学家，在（动态）价格歧视，纵向合并的竞争效应，产品差异化与价格竞争，知识产权与创新，以及消费者搜索与竞争等领域做出了重要贡献。陈勇民教授2012年以来一直担任RAND Journal of Economics副主编，并曾于2013-2019期间担任International Journal of Industrial Organization主编。
