itwbennett writes "According to a study (PDF) by the Georgetown Center for Business and Public Policy, restricting the ability of Verizon Wireless and AT&T to bid in upcoming spectrum auctions would drive down the bidding during the auction, and could cost the U.S. treasury as much as $12 billion. Even a partial restriction of bids by Verizon and AT&T could have a significant impact on auction revenues, said Douglas Holtz-Eakin, a co-author of the Georgetown study. Matt Wood, policy director at digital rights group Free Press, fired back, saying 'No one is talking about completely barring AT&T and Verizon from the incentive auction. Sensible people are talking about making sure that more than two companies have a chance at obtaining spectrum. The fact that these duopolists hired economists to parrot the companies' own talking points isn't really that newsworthy.'"
