【时间】2016年11月25日(周五)12:00-13:30

【地点】明主734会议室
【主讲】马悦 人民大学经济学院
【主题】 Competition in two-sided markets
【点评】程华 中国人民大学经济学院副教授
【摘要】Many markets involve two groups of agents who interact via “platforms,” where one group’s bene?t from joining a platform depends on the size of the other group that joins the platform. I present three models of such markets: a monopoly platform; a model of competing platforms where agents join a single platform; and a model of “competitive bottle necks” where one group joins all platforms. The determinants of equilibrium prices are (i) the magnitude of the cross group externalities, (ii)whether fees are levied on a lump-sum or per-transaction basis, and(iii) whether agents join one platform or several platforms.
