Welfare Analysis of Regulating Mobile Termination Rates in the U.K.
通过校准模拟模型分析英国移动市场降低终端费率的影响，发现可能增加消费者剩余和网络利润，社会福利每年可增加10亿至46亿英镑，并评估了2010年Orange与T-Mobile合并的福利效应。
We develop a calibrated simulation model of the U . K . mobile telephony market and use it to analyze the effects of reducing mobile termination rates ( MTR 's) as recommended by the E uropean C ommission. We find that reducing MTR 's is likely to increase both consumer surplus and networks' profits. Depending on the strength of call externalities (i.e., benefits to the recipient of a call), social welfare may increase by as much as £1 billion to £4.6 billion per year. We also use the model to estimate the welfare effects of the 2010 merger between O range and T ‐ M obile and find that the merger led to a substantial reduction in consumer surplus.
