The Effectiveness of Mobile Wireless Service as a Competitive Constraint on Landline Pricing: Was the DOJ Wrong?
11 December 2008
By Dr. William E. Taylor with Dr. Harold Ware
The US Department of Justice (DOJ) recently concluded that "the available evidence does not establish that mobile services currently represent an effective competitive constraint on landline access pricing." However, the authors of this paper disagree with that conclusion. The paper argues that data on price trends and substitution of wireless for landline services clearly demonstrate that mobile services represent an effective competitive constraint on landline pricing. The authors contend that, for some (perhaps many) customers, an increase in wireline prices will cause them to shift to wireless services exclusively. Thus any competitive analysis of wireline access service must take wireless services into account -- as wireline carriers obviously do -- together with cable and VoIP competitors.
