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 (EEA) when travelling abroad in the EEA. 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 vs. leisure).

移动互联网接入的福利效应：来自“在家漫游”的证据

我们评估了“在家漫游”法规的福利影响，该法规大幅降低了欧洲经济区 (EEA) 居民在欧洲经济区出国旅行时访问移动互联网的价格。我们使用个人消费数据进行的估算表明，每位用户和旅行日的消费者剩余增加了约 2.44 欧元。我们发现，大约 40% 的消费者剩余收益源自无谓损失的减少，即访问移动互联网的新用户。我们还强调，该法规对消费者产生了不同的影响，其影响因使用强度和旅行原因（商务与休闲）而异。
