Estimating Platform Market Power in Two-Sided Markets with an Application to Magazine Advertising
通过结构模型研究双边市场中平台如何在一侧亏损而在另一侧盈利，并分析平台合并对价格和用户数量的影响，适合关注平台竞争与反垄断的学者。
In two-sided markets, two groups of agents interact through platforms. Because agents’ decision to join a platform is affected by the presence of agents on the other side, their interactions create indirect network externalities and make platforms’ strategies different from those of firms in one-sided markets. In this paper, I use a structural model to show that platforms may take a loss on one side of the market to make a profit on the other side and that platform mergers may benefit some agents by lowering prices or attracting more agents on the other side of the market.
