Ebay is not like a Vickery auction. It's closer to an English auction. It's not sealed, but live. All the bidders have the chance to update their bid as they get outbid.

[@nnickers3355]

Not 100% Bidder A $10, Bidder B $100, bid shown $11 Bidder A doesn’t know how high bidder B’s limit is. They can keep bidding incrementally but have no idea if the bid is 100 or 10,000. So it’s a live Vickery auction but the actual winning bid upper limit is sealed until beaten and this cycle repeats. Most people bid last minute so you don’t ever see what the final winning bidder was prepared to pay you only see that they beat the 2nd highest bidder by a small amount.

[@MrScottyBaker]

@@nnickers3355 True, not 100%. But after Bidder A is outbid at $11, he has another chance to up his bid... even past B's $100 at anytime before the auction ends. In a sealed auction, they'd never have that chance.

[@SgtSupaman]

@@nnickers3355 , bidder B isn't actually bidding $100 to start with. What bidder B is doing is allowing the site to bid on his behalf while setting a hard limit at $100. Real people can do this exact same thing with open auctions in real life by having someone attend the auction and bid for them. Scott Baker is right; Ebay is definitely more of an open auction, not a Vickery auction.

[@Murtag32]

You're actually kind of both right. The key observation here is that English auctions are theoretically equivalent to vickery auctions (The bidder with the highest valuation will win and pay a price equal to the 2nd highest valuation). The key point of the video is that Dutch/1st price sealed bid auctions have different optimal strategies to english/2nd price sealed bid auctions (in one you bid shade, in the other you don't). Ebay is a english/2nd price sealed bid auction, aka vickery auction. Real life English auctions (and ebay) tend to have minimum bid increments for practical reasons (and to avoid user confusion) which makes them look different from sealed 2nd price auctions but that increment could theoretically be arbitrarily small, making them identical from a auction theory standpoint. Going back to ebay though, ebay is closer to vickery than an English auction as the optimal strategy is to bid your valuation and nothing else, being outbid and bidding higher again doesn't make much sense from an optimal strategy perspective - I would conjecture people don't like to lose so if they are outbid they feel compelled to bid again, even the price now exceeds their valuation. Or perhaps they think that's how you're "supposed" to bid, as they are copying what they've seen in English auctions. To counter this behavior though, some ebay users bid at the very last second of the auction (sniping) not giving the other bidders a chance to reconsider their bid. If all bidders do this, it looks even more like a vickery auction as all bids are essentially sealed. If we assume snipers bid their valuation (the optimal strategy), this has the interesting consequence that sniping is actually a good thing, as it leads to the socially optimal outcome (total combined utility is maximized).

"That's how ebay works". I thought it worked by everyone sniping in a bid for $1 at the last second of the auction, and whoever has the lowest lag wins.

[@codyhanson1344]

Nope, you just place whatever is the most you are willing to pay for such item on the day the auction ends, then it will automatically bid $1 more than the highest bid on your behalf until your max bid has been reached.

[@beez1717]

The issue here is that people use bots to try and get in at the last possible moment and force a win no matter what. That forces you to try and drive out people at the lowest price possible so you're free to make that last minute bid.

I thought they worked by the seller making his friends do fake bids in order to raise the price. Also there's a trick where they place a bid then cancel it so that they can see what is the exact sum that you did input.

[@silvadelshaladin]

I think the dutch style where you start at the highest number and work your way down is the best for the seller. The reasoning behind this is it is as here today gone tomorrow thing where if you don't grab it, it won't be there. It is a pressure thing where someone might jump at $570 when they want to pay $550 to avoid feeling bad when it sells at 551.

[@TheSuperappelflap]

an additional advantage is that there is a fixed maximum amount of time that the auction will take. once the clock runs out, the item will not be sold and returned to the seller. auctions where the clock runs up, can take much longer if people keep bidding against each other on an item, especially if they are increasing their bids by small margins each round. so for auction houses trading large amounts of items, like the dutch auctions that sell plants and vegetables, this makes it easier to schedule their auction days and guarantee a minimum amount of items that will be on auction on that day.

As someone that spent 5 years writing auction software for use in auction houses around the world I can tell you that the sketchiest and least honest part about the whole process are the auction houses themselves. There are a few reputable ones out there but most are not. The type of auction in this video is easily abused by an auctioneer by just making up fake bids just below the highest one. In fact the majority of companies we dealt with would do this. Harder to get away with in person but for online bidding it is trivial. It is critical that the auctioneer does not know the highest bid.

Another cool thing about Vickrey auctions is that not only are people incentivized to pay what they want, they also are guaranteed to pay less than that amount if they win, meaning they get the item at what they see as a bargain.

[@jcb3393]

Everyone: "But Vickery auctions must only be done for high-priced items like art masterpieces and oil fields." eBay: "Hold my beer."

[@thecompanygardener]

I think a big psychological component of the Vickrey auction isn't just knowing that you're getting it for no more than you value it at, but that there is a market (at least one buyer) at the price you paid.

[@joshyoung1440]

Yes but how unsure of your own decisions and desperate for reassurance do you have to be for a market of 1 to be any kind of reassurance whatsoever? I mean I personally have a horrible obsession with how I'm perceived but even I make my purchasing decisions based on what I want alone and don't consider much else lol

[@andrewlitvinov7266]

Vickrey auction seems like an attempt to emulate an open auction in a closed one. You're effectively setting a ceiling for what you're willing to pay, which is what people do when the enter an open auction. So the person with the highest ceiling wins and pays a (minimal bid amount) above the second-highest.

Interesting fact: The ancient Babylonian auctions written about by ancient Greek historian Herodotus (mentioned at 10:24 of the video) were actually marriage markets. This is what he wrote about them: "In every village once a year all the girls of marriageable age used to be collected together in one place, while the men stood round them in a circle; an auctioneer then called each one in turn to stand up and offered her for sale, beginning with the best-looking and going on to the second best as soon as the first had been sold for a good price. Marriage was the object of the transaction. The rich men who wanted wives bid against each other for the prettiest girls, while the humbler folk, who had no use for good looks in a wife, were actually paid to take the ugly ones, for when the auctioneer had got through all the pretty girls he would call upon the plainest, or even perhaps a crippled one, to stand up, and then ask her who was willing to take the least money to marry her - and she was offered to whoever accepted the smallest sum. The money came from the sale of the beauties, who in this way provided dowries for their ugly or misshapen sisters. It was illegal for a man to marry his daughter to anyone he happened to fancy, and no one could take home a girl he had bought without first finding a backer to guarantee his intention of marrying her. In cases of disagreement between husband and wife the law allowed the return of the purchase money. Anyone who wished could come even from a different village to buy a wife." Herodotus then laments how this "admirable practice" has since fallen into disuse in favour of prostitution.

Would it be a good idea to do this in reverse? Say you needed a job done, like having your roof reshingled, would it be a good idea to get bids from several companies and then pick the second lowest? Would it stand to reason that the company that put the lowest bid would cut corners or do shoddy work, where as the next to lowest would be likely to have given a low bid but actually have been more honest in what it would take to actually do the job correctly?

[@QBAlchemist]

I would argue that the Ebay auction method is not the Vickery method. The Vickery method relies on the bids being revealed and the auction concluding at a single period of time - bidders only being able to bid a single time with their honest/maximum bid. While I can understand why the Ebay method appears similar: a bidder can enter a single high bid, and the Ebay system will only charge you for the 2nd highest bid plus the increment; In fact, this is just some 'operational sugar' on the standard English auction. Ebay will simply remember your highest bid, and then every time a new bid is placed on that item, it will check to see if your highest bid out-ranks it, and will automatically re-apply your new bid over theirs. Note, you do not win instantly, and opponents have the opportunity to increase their bid beyond their normal maximum if they so choose, without the risk of potentially losing value since they already know your current highest bid. If I am not mistaken on my understanding, the clip of the Ebay bidding at 9:36 supports my claim. Personally, I don't think it matters all that much for the content of the video. The Vickery method is still the preferred method, and the video information is still accurate - I just believe based on my current knowledge that Ebay does not in fact use the Vickery method (though I wish it did).

[@caseclosed9612]

"... painting collector McGee, someone I just made up..." Oh ok thanks for the clarification

[@endymallorn]

The major problem with what you're saying is that eBay is not a sealed bid system. Yes, it's a second-offer auction setup, but with open bids and a minimum bid higher than either a reserve or the last bid in a progressive ascension. If I'm bidding on an item, it's in my best (i.e. most selfish) interest to get in as the second or third bidder on the auction, and having seen a lowball or reasonable price, to increase the bid higher than what I believe anyone else will be willing to pay - a strategy very similar to what occurred with your $8.000 bid. In a sealed second-price auction, the best move is to bid marginally higher than I believe is a fair price for the item, but still in the range I would pay - because either I will win with my high bid or I will both benefit the seller to a greater degree and I will hurt the person who followed my same strategy. This encourages the seller to list more items more often, and it discourages that other selfish buyer and those who observed the results of the auction. Selfish bidding is consistently the most effective means of bidding in a second-offer system. You lose nothing by a high bid that either wins or loses. A fixed-offer sealed auction is the only one that encourages unselfish behavior.

Second best price is the "best price" though. If it was an open auction do you think C would bet $200 after hearing B's bet of $150? C would bet $151 which is out of the budget of B and thus he would win and pay the best price (which is the second highest bid). Nobody is going to raise the bid directly to their maximum budget (unless they are flexing).

The Auction I join is similar. I can bid up the old fashioned way, or enter a Maximum bid. Say I put in a maximum bid of $300, and the other bidder stopped at $160. My auto bid would then win me the item at $170 as that is the next bid increment. Most of the time, I am outbid. However sometimes, they have an item the bidders are not looking for, or it is poorly attended. At those I pick up some great deals. For example, bought a pallet of PC's at a government surplus auction and averaged $25 each for them. Had a heyday on CL selling them from $100 to $200 each depending on memory and processor. Last week got a dozen LCD monitors for $ 10 each. Selling them for $20 to $50 each depending on the model and screen size. Sold 5 of them as a batch today. Love a good government surplus auction.

They should make an auction where the bidders pay their bid no matter if they win or not. I can't even imagine what it would go like, you'd think that people would just bid very low and the auction wont profit, but if there are a lot of people they might actually get more money.

[@JebeckyGranjola]

Isn't that how Honey or w/e works? I thought of this too, i'm pretty sure there is a site like that. I'd imagine the seller lists a mandatory price and as long as the total reaches it (or exceeds it), then the highest bidder gets it.

Hm. To my memory there were some who had purposely outbid everyone on stuff from these auctioning sites and then just canceled their thing. Adding features on top of things that work may break stuff.

Why is this balloon talking about auctions?

[@DCMCOSPLAYdotCOM]

One thing, many people do not bid honestly on ebay. Sure the system used is honest in theory, but often someone will bid, are beaten by a pro gamer strategy, then wait until the auction is about to end, and then play their honest hand. When it's sealed envelopes, you go as high as you think its worth because that's the only way to be sure. But on ebay, as long as the clock is running, opponents have a chance to perhaps, bend a little further and pay more than what they honestly thought it was worth. This is compounded by the whole "if someone else thinks its worth that... maybe it is" train of thought. All I got to say is, Im glad ebay doesn't extend the clock when a bid comes in like Yahoo auctions did. ^_-

Pov: you're trying to comment something funny

[@CoxTH]

There is a key difference between a standard Vickerey auction and eBay, though. In the standard auction, everyone submits their bid at once and the bids are revealed in the end. In an eBay auction, the bids are "open" in the way that each bidder at least knows the second-highest bid. So the ideal strategy in an eBay auction is to wait until the very last second to bid, giving the highest price you're willing to pay. This practice is called bid sniping and the most common way these auctions are won.

There actually isnt a "Nobel Prize for economics", Alfred Nobel rightfully only wanted real science to get his prize. The Prize for economics in memory of Alfred Nobel is something economists came up with to legitimize their mostly whacko theories.

Let's just appreciate the phenomenal background music for a bit.

[@DoubleOhSilver]

We're missing information. By the video, the $8k bid strategy still works because you didn't mention how the $8k doesn't have to be outbid during the auction. The price of the item raises and your bid is used up to keep you in the lead. So if you bid $8k, the item can jump to $1200, but you'll stay the highest bid until all $8k is used up. So it's less of "you pay the second highest bid" and more that the item price and bid are two independent numbers.

[@Stubbari]

Well, if you value the product at 8k then of course the 8k method is going to work. If you value the item at $550 but bet 8k just to get the item then most likely you are overpaying.

[@RialVestro]

There's another weird type of auction and most players don't even realize it works this way... In City of Heroes they have a highest bidder/lowest seller auction. When you go to sell an item you set the lowest amount of money you're willing to sell the item for. However because of the way the auction system works the person who bids the highest on an item will always buy from the person who sold for the lowest price. Because of this the same item can be posted for 9 influence/infamy (The currency of the game) and 1,000,000,000 inf. While you can't get a bid lower than your sale price you also will be unlikely to sell an idem at all if you set the price high and if it does sell it won't be for any more than what you actually set the price at. Because the highest bidder always buys from the lowest seller, items sold at 9 inf will actually sell much higher, the highest price possible that anyone is willing to pay for that idea. By selling high you might be low balling yourself, not getting the best value for the item you're trying to sell and may not sell at all if your set the price too high that no one is paying. But by setting the Price low, at 9 inf you're guaranteeing that you will always make a profit no matter what the item actually sells for because you're guaranteed to get the highest bid on that item. The reason you need to sell for 9 instead of 1 by the way is that the Auction House itself charges a minimum fee of 5 inf. If you sell an item for less than that and the highest bid at the time is also under that price you risk spending more money than what you would Earn. So 9 inf is the lowest price you can sell and still make some kind of a profit even if the bids are low. As far as I know this kind of bidding only exists in that game and even though the develops said that's how the auction house works I've found that most people never read that and just assumed when they saw "Auction House" that it worked like a normal auction... it doesn't. I got rich in the game selling items for 9 inf. cause most people sell high I always get the highest bid available at any given time. I've gotten anywhere from 110 to 50,000 on items I only posted for 9 inf and if I actually set the price at 110 to 50,000 they'd likely never sell at all. Some people actually set their sales price based on the highest price sold in the past and never sell anything unless the prices get inflated... which they fluctuate daily but it can take weeks to sell anything that way.

[@SuperYoonHo]

Thank you!

[@jcthefluteman]

9:30 ‘the seller knows they’re gonna get the best price for their item’ Look I may be missing the point here, but I’m pretty sure $8000 is *always* a better deal for the seller than $550 I watched this whole video twice and I still don’t get how this system is better than regular auctions

[@Vaaaaadim]

In the auction system that the video talks about, the highest bidder pays what the second highest bidder had bid. The bidding strategy changes if the bidding system is different. Kevin is saying, hypothetically, in this bidding system you could imagine someone takes this strategy where they bid ridiculously high, so that they always win. But that actually this strategy would be a bad idea.

[@Stubbari]

What do you think is going to happen in a regular auction (English auction I assume)? Do you think when person A bids their upper limit of $550 person B is going to slam out $8000? No, they are going to raise the bid to $551 (or whatever the minimum raise is). So instead of wasting going back and forth raising the bids we go directly to the second highest bid which is the price of the product in both cases.

[@Fluxikator]

In regards to eBay: it would be interesting to see what would happen if they used concealed random auction end. For example. It's just stated that the auction ends around 1 o clock. But the exact end is at radom between let's say 12.50 and 13.10. but without telling the bidders.
