When you submit a bit do eBay using the traditional method, your bid is
really a proxy bid--it's increased by specified increments until it's
outbid by another bidder. If you prevail, you win by the minimum
winning proxy bid.
?.
If the successive bids are at a constant ratio (is it still 5%?) that is
eBay making public higher and higher portions of the not-to-exceed (but
still private) value that person originally entered.
The other possibility is that the original bidder, on being outbid, lets
their competitive instincts get the better of them and enters a higher
not-to-exceed bid ? and then a higher one ?
if the successive bids have a minute or two between them, or a
non-constant ratio, that is likely what is happening, and it?s a *great*
reason shills exist in the first place. I think the original intent of the
eBay system, and my recommendation, is that folks dispassionately, calmly,
decide what their true ceiling is, enter that value the first time, and
then walk away. eBay doesn?t promote that behavior now, though. The ?you?ve
been outbid! But there?s still a chance!? email they send seems pretty
calculated to stampede you into competitive behavior. I suspect that leads
to regrets.
Yes. It drives more traffic to the site. It's really gamification of the
process, which sucks for the bidders (they bid more than they should). In
the ideal world, you set a price you're willing to pay, pay a trusted third
party to place that bid in the closing minutes of an auction. It limits the
amount of information that you give to ebay and/or the seller. The only
time there's an issue is if there's another bidder whose top bit is exactly
the same as yours and they bid first. It's a pretty small benefit from
bidding first vs the tendency for others to bid if they see your bid
early.... Last second bids also limit the window in which someone else can
game your vote, and wondering if someone is shilling you or not...
