研究社交网络中互操作性对竞争性价格歧视的影响，通过两个差异化平台设定个性化价格，得出任意网络的均衡价格包含与Katz-Bonacich中心性成比例的网络位置项，互操作性会软化价格竞争，改变市场从价格歧视中获利的方 面。
AI 中文摘要
我们研究当消费者嵌入社交网络时，互操作性如何重塑竞争性价格歧视。两个差异化平台设定个性化价格，消费者受益于邻居对同一平台及在互操作性下对竞争对手平台的消费。任意网络的均衡价格以封闭形式得出，包含与Katz-Bonacich中心性成比例的网络位置项，其符号由互操作性是否超过产品可替代性决定。低于阈值时，平台争夺中心消费者并给予中心性折扣；高于阈值时，中心消费者成为共享跨平台网络的网关并支付溢价；在阈值时，价格与网络位置无关。互操作性软化价格竞争，可使平台青睐更密集的消费者网络，并扭转市场哪一方从价格歧视中获利的局面。
英文摘要
We study how interoperability reshapes competitive price discrimination when consumers are embedded in a social network. Two differentiated platforms set personalized prices; consumers benefit from neighbors' consumption of the same platform and, under interoperability, of the rival. Equilibrium prices obtain in closed form for arbitrary networks and contain a network-position term, proportional to Katz-Bonacich centrality, whose sign is determined by whether interoperability exceeds product substitutability. Below this threshold, platforms contest central consumers and grant centrality discounts; above it, central consumers become gateways to a shared cross-platform network and pay premia; at the threshold, prices are independent of network position. Interoperability softens price competition, can make platforms favor denser consumer networks, and reverses which side of the market gains from price discrimination.
