Suppose there a three bidders competing in an ascending price auction for a piece of art. Their valuations for the art are 100,100, 200 and $300, respectively. What is the clearing price of the art.


In an ascending price auction, also known as an English auction, the bidders keep raising their bids until only one bidder remains, and that bidder wins the item at the final bid price. The clearing price is the price at which the winner obtains the item.

Given the valuations of the three bidders for the piece of art:

  • Bidder 1: $100
  • Bidder 2: $200
  • Bidder 3: $300

In an ascending price auction, the bidders will continue to bid until the price exceeds the valuation of all but one bidder. In this case, the auction will proceed as follows:

  1. The bidding starts at a low price, let's assume $0.
  2. Bidder 1 will bid up to their valuation of $100.
  3. Bidder 2 will outbid Bidder 1 by bidding higher than 100,say100, say 101.
  4. Bidder 3 will then outbid Bidder 2 by bidding higher than 200,say200, say 201.
  5. At this point, Bidder 1 and Bidder 2 will drop out of the auction since the price has exceeded their valuations.
  6. Bidder 3, being the last remaining bidder, wins the auction and obtains the piece of art.

The clearing price, which is the final price at which the winner (Bidder 3) obtains the item, is $201.

Therefore, the clearing price of the art in this ascending price auction is $201.
