The Welfare Effects of Mobile Internet Access: Evidence from Roam-Like-at-Home
研究了欧盟“像在家一样漫游”法规对消费者福利的影响，发现每位用户每旅行日消费者剩余增加约2.44欧元，其中约40%来自新用户接入带来的无谓损失减少，且影响因使用强度和旅行目的而异。
Abstract We evaluate the welfare effects of the Roam-like-at-home regulation, which has drastically reduced the price of accessing the mobile Internet for residents of the European Economic Area when travelling abroad in the European Economic Area. Our estimates using individual-level consumption data suggest that consumer surplus increased by around €2.44 per user and travel day. We show that around 40% of the consumer surplus gains originated from a reduction in deadweight loss, that is, new users accessing the mobile Internet. We also highlight that the regulation had a heterogeneous impact on consumers, varying with usage intensity and the reason for travel (business versus leisure).
