The article explores how sellers might offer non-winning bidders a second chance to buy at their bid price after an auction. Different auction types were studied to see how this second chance offer affects bidder behavior.

Risk-averse bidders tend to prefer second price or English auctions over Vickrey auctions. Overall, the first price auction was shown to generate the most revenue compared to other auction types.
