Information Acquisition During a Descending Auction

Author

Listed:
  • Wambach, Achim

Abstract

If bidders can acquire information during the auction the descending auction is no longer equivalent to a first-price-sealed-bid auction. Revenue equivalence does not hold. The incentive to acquire information can even be larger in a descending auction than in an ascending auction.
