CESifo Working Paper No. 9235

We empirically assess the impact of the EU roaming regulation on mobile operators’ average revenues per user (ARPU) and retail prices. Using a differences-in-difference approach, hedonic price regressions and detailed operator and plan-level data we find that the regulation decreased mobile operator’s revenues per user, while it had no impact on tariffs during the latest phase of the regulation.
