Empirical Evidence on the Relationship between Mobile Termination Rates and Firms' Profits
研究了移动终端费率（MTR）统一变化对运营商利润的影响，利用欧洲饱和市场面板数据发现，当运营商提供包含固定使用量的套餐时，MTR统一变化不影响零售价格或利润。
Abstract The theoretical literature on mobile termination rates (MTRs) is inconclusive on how the level of MTRs affects overall consumer charges and firms' profits. We show that when firms offer bundles with fixed included usage – a tariff structure that has become more common in recent years – an identical change in all MTRs does not affect firms' retail prices or profits. We use a panel dataset from saturated European markets to estimate the effect of MTRs on mobile operators' profits. As predicted by the theoretical model, we cannot reject the fact that firms' profits are unaffected by an identical change in all MTRs.
