Summary

Some electromagnetic spectrum is used inefficiently. In reclaiming this spectrum for allocation to more efficient uses and users, the FCC may choose between a simple overlay auction and a more complex two-sided auction.

Policy Relevance

Two-sided auctions can enable the FCC to safeguard competition and reduce costs. Sometimes, a simple overlay auction is better.

Main Points

  • The Federal Communications Commission (FCC) seeks to reclaim inefficiently used electromagnetic spectrum for new uses and users, but incumbent spectrum users impede this transition.
     
    • Before the 1990s, spectrum licensees were often limited to small geographic sites or to specific technologies.
       
    • Now, licensees are granted rights over wider geographic areas and the flexibility to adopt new technologies.
       
  • The FCC’s main goal in repurposing spectrum is to support competition between wireless service providers, while minimizing transaction costs and holdout costs.
     
  • Auctions award licenses to the highest bidder, meaning that spectrum auctions do not always maximize the benefits to consumers from competition; generally, the FCC encourages competition by restricting eligibility to bid and setting aside spectrum for some bidders.
     
  • In an "overlay" auction, incumbent licensees keep their original rights and duties, but the "overlay" licensee acquires all other spectrum rights (such as the right to secondary uses of existing channels); the overlay licensee may negotiate with the incumbent to coordinate new uses of the band.
     
    • The overlay licensee could pay the incumbent to cease transmission and give up its rights.
       
    • Overlay auctions rely on market forces, and overlay licenses can be implemented quickly.
       
  • One important market-based alternative to the overlay auction is a centralized two-sided auction, in which the FCC serves as market maker and can add command-and-control rules as needed.
     
  • The FCC’s 2016 Broadcast Incentive Auction, in which the FCC reclaimed spectrum used by television broadcasters, shows that a two-sided auction can be superior to an “overlay” auction.
     
    • The FCC first held a reverse auction, offering payment to the television broadcasters to vacate the spectrum; at the end, some remained.
       
    • Next, the FCC auctioned reclaimed spectrum to new wireless service providers.
       
    • The FCC ordered many remaining broadcasters to relocate to new spectrum.
       
    • The FCC’s supplemental rules fostered competition between new service providers.
       
  • Without the FCC’s power to require broadcasters to relocate, broadcasters could have held out for large payments from new licensees, raising the cost of the transition; an overlay auction of this spectrum would have required thousands of negotiations between broadcasters and new licensees.
     
  • In deciding whether to use a simple overlay auction or to use more complex rules, the FCC should first consider how much of the band is occupied by incumbents; if few incumbents are present, the FCC will have less need to mandate relocation to reduce the number of negotiations.
     
  • If new users can easily avoid conflict with incumbents, there will be less hold-up, and an overlay auction could be used.
     
  • When observers do not know whether the incumbent service or a more flexible service would be more valuable, an overlay auction might be better.
     
  • Large amounts of spectrum are not licensed for flexible use; overlay auctions could be useful for the remaining television bands.
     
    • The FCC will be unable to relocate incumbents to new facilities.
       
    • This spectrum is not critical to maintain competition between wireless services.
       
    • Overlay licensees may slowly to buy out incumbents.
