Complained to EBay but they did nothing. In the end, I waited a while after the shill's last bid, then put in a bid of my own. The shill really quickly raised it again a few times then withdrew his last bid that topped mine. At which point, I withdrew my last bid and left the shill in the winning position with a few seconds to go and a bid that was too old to withdraw.

    No, you still got it 3$ to cheap, because you were willing to pay 20$. Your argument is a logical fallacy.

    No.

    In economics, there is a long established and useful concept called consumer surplus. It is based on the fact that some consumers value an item at much higher than the going rate, but that their number is small enough that it would not be in the seller's interest to sell a smaller quantity at a higher price.

    For example, say that I am extremely hungry and have a class in 10 minutes. I might be willing to pay $5 for a slice of pizza at the cafeteria nearest to my classroom, due to reasons of both timing and hunger. However, since the cafeteria can't read people's minds, and because of various local trade laws and issues of practicality, they must charge the same price to everyone. Say that the optimal price based on average demand and the cost of supplying pizza, both in labor and materials, is $1.50. So I buy a slice for $1.50 and I am left with a consumer surplus of $3.50.

    This example is to say that people often value an item above the market clearing price (or below it, in which case they don't buy), and that the fraud being committed is fraud, because it artificially inflates the market price with bids of buyers who do not intend to pay, and who are in collusion with the seller.

    In our pizza example, if a store employee out of uniform had stood next to me and tried to outbid me on pizza, until my reservation price ($5) was reached, that would be fraud. When someone misrepresents themself in a commercial transaction, it is fraud. All the bidders are transactors in an auction, not just the winner.

    The problem is that once an item is received, most people rate it instantly and then don't have any obvious way to revise their rating.

    Right, that's the way real world auctions work. Ebay has different rules. I do believe back when ebay started and there was actually serious competition, there was another online auction house for which snipeing did not work. On that system, whenever a bid was placed, the auction was extended to last at least another 5 minutes. Thus, you couldn't snipe. Now, similar to an ebay auction it meant you might have to go to the site or read your email and rebid if desired. It also meant you didn't know how long you'd have to watch that auction before it would finish. In the end, we can see ebay didn't go that route. I think people found just bidding their maximum offer works just fine and haggling for an hour at the end of the auction wasn't worth everyone's time.

    If you've bid the maximum amount you'd be willing to pay for an auction, the only thing a snipe bid denys you is the better deal you were hoping to get. If they bid earlier, you'd still not get that better deal. The sniping just let you hold onto the hope a bit longer. Why do I snipe? I don't want to deal with the people who don't bid their maximum amount, watch the auction for competition, get emotionally invested in winning the auction, and push up the price I have to pay. By sniping the auction for the amount I'm willing to pay, I win the auction for what I'm willing to pay, and don't if the auction goes higher. There are 2 useful differences between this and a standard bid:

          1. People don't get to look at my bid and respond to it. Their bid of how much they're willing
                to pay is the only response they get.

          2. My bid is retractable up until the time of the auction. This means that I can bid on 10
                auctions for identical (to me) items, and stop the other bids if i win an auction.

    I find the 2nd benefit quite useful. Ebay doesn't offer anything like this ability. I often shop for items on ebay, find 10 perfectly reasonable auctions, but on ebay I can only bid on 1 auction at a time. Using a sniping system, I can bid on all and set it up to stop when it wins an auction.

    Sniping isn't about being an irritant to anyone else. It's just more efficient. If ebay itself offered this bidding option, the seller would essentially get no feedback on his auction until the end, and there wouldn't be any bidding wars to raise the prices. There also wouldn't be any shill bidding, as a reserve bid would work just as well. In my opinion, using sniping bids makes you be diciplined about your bid. You must carefully decide what your maximum bid amount should be (but, you can also change that before the end of the auction, but you can change it up _or_ down). In my opinion, if you're not using the snipe bidding, you aren't shopping as efficiently and carfully as you could.

    I took part in an auction a few months ago which seemed to me to be a clear cut case of shilling. I put a low-ball bid in on a video game, got outbid, and came back the next day (after purchasing it elsewhere) to find that the winning bid that outbid mine had been cancelled but that my bid had been extended to its very top value (I think it was at $1 when I first took the top spot and I'd only offered up to $2). So before paying, I inquired with the seller as to why the other bidder's bid had been retracted. I made no statement toward either having bought the item elsewhere or toward ebay's narrow criteria for allowing retractions. I simply asked why it happened, and the reply to me was something like "Well if you don't want to pay, you should have said something sooner" or some similar BS. So then I wrote a message to the shill bidding department asking for advice of how I should proceed since, as far as I could tell, the anomolous bidding had disrupted the integrity of the auction. A few days later, I recieved an email from their loss prevention department stating hat the seller's account had been terminated and that I should not pay for the auction, as well as informing me of a few options for how I could get a refund if I had already paid. My only complaint about the process is that the form letter said I would be informed of the results of their investigation in 24-48 hours, but it was more like 72.

    But anyway, there's are two strong motivations for ebay to enforce a strict anti-shilling policy: first, it's illegal in many places. Second, and more importantly, is that setting a reserve price is /not/ illegal, and they get a larger cut for auctions configured for reserves. Simply setting a reserve guarantees that ebay will receive no less than 1% of the reserve price (and substantially more for items less than about $150). If they allow shill bidding to take place, they lose money. For example, suppose you have a playstation 3 you want to sell and you don't want to let it go for less than $850. If you start the auction at $850, you pay $4.80 to insert it. If you start the bidding at less than a dollar, you take the risk of not meeting your final price, but the insertion fee is cut to only 20 cents. If you start bidding under a dollar and place an $850 reserve, it's %8.70 to start the auction. In each case, closing costs would be 3% of the winning bid plus 56 cents (since it's 5.25% on the first $25). So in this example, if a shiller were to start bidding under a dollar with no reserve, they would have to push the price up to about $1000 or $1130 for the closing fees to match the higher starting bid and reserve situations above, respectively. And the lower the final price, the bigger the difference is in the fees. In the case of an item with a 49.99 reserve selling for $50, the same item would have to sell for $83 without a reserve to generate the same fee. While it is possible that they could make more money by looking the other way for shills, there's a strong chance they'll alienate their users with high prices and frustrating auctions, face legal action if it can be shown that they looked the other way, and in all likelihood make less money than if they were to do the job themselves with reserve prices. Behold the almighty dollar.

    Ebay only pushes your bid up to the reserve if your maximum is over the reserve. If your bid is below the reserve it allows it to stay at the starting price (or does the normal bidding war between you and the other seller).

    Ebayers get into a religious war about sniping (and every conceivable "feature" in the system) and generally resort to this "you're a moron, I'm a professional" baloney.

    No, the problem is they're combining a Vickrey auction with an English auction--then adding an arbitrary stop-watch--and that encourages sniping and rampant shill bidding. People who point this out aren't morons, they just recognize a bad system when they see one.

    For bid once, bid max to work, you actually have to be forced into having only ONE bid. Once you can submit subsequent bids, no one will reveal their true max until the last possible moment, because you have no reason to believe anyone else will behave any differently. The stopwatch identified by the previous poster IS the problem. Because of the combination of sealed-yet-easily-opened bids, you reduce it to a few seconds of English auction with the reserve set by a week of unfortunate souls who've tipped their hands. What you end up with is underbidding for fear of being automatically ratched-up by shills and overbidding in a desperate attempt to outrun the shills and everyone else in a sprint to beat the clock hoping to god no one else has overbid /worse/ than you because you're hoping that last millisecond $50 up only costs you $0.50.

    This is not good auction design, but it is easily fixed: enforce single-bids or reset the clock. If you do the former, you force the humans to be truthful--and completely eliminate any incentive to shill--and if you do the later, you remove the incentive to engage in the robotic 100 millisecond dash.

    But, one can imagine that some very talented statisticians at eBay have figured out that the current system results in significant net overbidding and that means more money, so while it may be broken, they ain't going to fix it any time soon.

    In my county, we have petitioned the authorities to put a blanket ban on the site.

    So which of your countries is it? USA? Canada? The Netherlands? County != Country ...
