Auction Designs Play Critical Role in Successful Privatizations
August 1, 2002
Governments that seek to maximize revenues from the sale of state-owned properties should pay particular attention to how their auctions are designed.
A recent paper by Oxford University economist Paul Klemperer stresses the need to encourage entry by bidders and discourage collusion among them.
Here are a few tips from his study:
- Ascending-bid auctions, particularly when they involve only a few bidders, are particularly susceptible to collusion -- since participants can use early rounds to signal intentions.
- In a German auction of mobile-phone spectrum several years ago, two participants encoded in their bids offers to compromise and threats to punish -- and each walked away with spectrum at a very low price.
- Prior to auctions, companies have used news releases and interviews to scare away potential competitors -- and in the case of a Swiss auction, obtained valuable spectrum at a fraction of the expected price.
- In an Australian sealed-bid auction for satellite television licenses, one company submitted several different bids on the same licenses and then, after winning, defaulted on the bids that were too high -- paying a price only slightly higher than the amount bid by the next highest bidder.
To avoid such pitfalls, Klemperer recommends the "Anglo-Dutch" auction. This employs an open, ascending bid-auction until only two bidders are left. Then they must go head-to-head with final sealed bids.
