"In a first-price sealed-bid auction, bidders are incentivized to shade their bid—that is, to offer less than what they consider the object's true value to avoid overpaying."
"The highest bidder still wins but only pays the amount of the second-highest bid, creating a space for transparency and honest bidding."
Blind auctions present challenges as bidders grapple with the uncertainty of how much to bid. Traditional first-price sealed-bid auctions incentivize underbidding to avoid overpayment. However, economist William Vickrey proposed an alternative: in a second-price sealed-bid auction, the highest bidder wins but pays the second-highest bid. This method encourages bidders to bid their true valuation, removing the strategic guessing game and promoting honesty in the bidding process, which has influenced real-world auction practices and earned Vickrey a Nobel Prize in economics.
