Should I stay or should I go? Migrating away from an incumbent platform
研究了正消费外部性市场中现有平台的优势，发现用户有动机等待他人迁移，导致即使迁移能带来帕累托改进也无法实现，且更多迁移机会反而增强现有平台优势。
Abstract We study incumbency advantage in markets with positive consumption externalities. Users of an incumbent platform receive stochastic opportunities to migrate to an entrant and can either accept them or wait for a future opportunity. In some circumstances, users have incentives to delay migration until others have migrated. If they all do so, no migration takes place, even when migration would have been Pareto‐superior. We use our framework to identify environments where incumbency advantage is larger. A key result is that having more migration opportunities actually increases incumbency advantage.
