Hi, just had a discussion with a friend about this. Just some details, eBay auctions are some sort of "half-blind" auctions, where the highest bidder wins, but you do not enter your actual bid. The sale price is equal to the maximum the SECOND highest bidder bids, plus a little extra. You do not make a single bid, you enter the maximum you are willing to pay for this item. For example, if I bid $40 and John bids $30, I win, but the sale price is somewhere around $31. If John upped his bid to $35 I would still win but the sale price might be $36. If he ups his bid to $41 the sale price is $41 and he wins. So my friend holds the opinion that "sniping" is optimal for getting the lowest price. This is where you bid at the last possible moment. I think that the time of bidding is irrelevant until people begin to react to the dynamics of the information that is available to them (the sale price, and the number of bids, and specifically NOT the maximum bid). I cannot formulate an example in my head where "sniping", would earn you a lower sale price than the alternative. Can anyone help resolve the issue?
