Competition for Access: Spectrum Rights and Downstream Access in Wireless Telecommunications

In the market for wireless telecommunications, radio spectrum is an essential input. The authors study downstream entry and capacity choice in this market, where licenses to use radio spectrum are owned by vertically integrated duopolists. Prior to network construction, these incumbents may offer contracts for capacity to an entrant, granting service-based access on the network they will construct. Alternatively, when spectrum trading is allowed, they may sell part of their license, allowing the entrant to build its own network and enter as an infrastructure player.
