The solution, assuming they actually want one, is really simple: setup a Vickrey–Clarke–Groves auction.
Frankly, I doubt the premise, though. Conventions are basically advertisement, and I suspect the chaos regarding prices is actually part of the plan all along.
- ivanbakel 6y agoCould you clarify this a bit? It sounds like an auction would just be a more complicated way of raising prices, since the tickets would still go to those customers who are able to bid the most.
- qsort 6y agoYou can run auctions in a bunch of different ways; in particular Vickrey–Clarke–Groves has rules such that the optimal strategy is for each participant to bid their true evaluation. Of course the prices are going to increase. If the supply is the same and the demand increases, the price increases. There is nothing anybody can do about that.
- AndrewDucker 6y agoFTA: "Yes, we’d get to line our pockets with money for days, but we like to think of PAX as the show for the every-gamer, and if we didn’t keep badges affordable, it’s not fair to those that can only afford our current price."
- qsort 6y agoScalpers are already effectively increasing the price. If the price of the event is $100 and I value it at $300, I'm going to buy from a scalper at $200. It would be more fair to "distribute" the price increase among all participants by using an auction method that incentivizes people to bid their true evaluations. I don't want to be unfair to the guy, he seems to be understanding the problem and it's not an easy decision, but that sentence is a bit of a platitude.
- AndrewDucker 6y agoAs they say, it's only affecting about 1% of their tickets. So 99% of people aren't having their prices inflated.
- qsort 6y agoIf that is the case, then it follows that the expected price increase would be approximately the same in a Vickrey auction (barring extreme cases where the bids have sharp discontinuities).
- ivanbakel 6y agoHow does that follow? The PAX organisers are "artificially" keeping down the price of tickets by controlling supply and fighting scalpers. If instead the auction allowed potential attendees to pay more for their tickets, then those tickets would end up going to attendees that pay far above the original price - as is already true for scalped tickets. The percentage of tickets which are scalped is not a direct function of the demand on tickets.
- qsort 6y agoBecause if a ticket is traded at $X, it means that there exists someone who believes it is worth $X or more. PAX is effectively offloading the additional cost to the excluded audience, by either denying a ticket they would be willing to buy, or by making them pay more than they would have. If the fraction of the scalped tickets is low, then it means that the fraction of people who are willing to buy a ticket at a price much higher than the going price can't be that large. If tickets were sold at $1, you'd certainly see A LOT more scalping going on, wouldn't you? This would in turn imply that the global outcome wouldn't be that different. People who really want a ticket get one either way, and people who kinda want a ticket benefit from the more fair allocation system.
- ivanbakel 6y ago>If tickets were sold at $1, you'd certainly see A LOT more scalping going on, wouldn't you? Not necessarily - you're discounting the effectiveness of anti-scalping measures. (And moreover, scalpers are always incentivised to scalp as many tickets as possible, because they are then put in the situation of controlling the market price with reduced supply, so that they can jack up prices). If in fact anti-scalping works effectively, then the market price of the ticket in a fair auction can be completely independent of the original price it was sold at. If demand is high enough, you can even have people who can only buy tickets because of the fixed price - if even 20% of customers are willing and able to pay far above the retail price for a ticket, they would in an auction snap up all the tickets, because PAX is oversubscribed by 5-to-1.
- 3np 6y agoMyself I was thinking it’d make sense with some variation of Dutch auction in rounds, where all participants in a round get the same price. What would you say the upside of VCG is? Dutch seems simpler and fair to me. https://en.wikipedia.org/wiki/Dutch_auction https://en.wikipedia.org/wiki/Dutch_auction
- qsort 6y agoA Dutch auction is more or less strategically equivalent to a first-price, sealed-bid auction. The advantages of VCG over that would be: - it's easier to implement. Dutch is admittedly easier to understand, but with VCG your average buyer would only need to fill a box in a form. - there is provable dominance of truthful bidding There are also downsides, admittedly: - it doesn't maximize seller revenues - it doesn't work if all bidders collude (unlikely in this scenario) - a dishonest seller could use shill/fake bids to increase the going price
- philihp 6y agoCall me chaotic neutral, but an auction for a Penny Arcade convention should really be a penny auction.
- ginko 6y ago>Of course the prices are going to increase. If the supply is the same and the demand increases, the price increases. There is nothing anybody can do about that. The profit over the targeted ticket price could be returned uniformly to ticket holders. I guess this would be hard to do in practice and may complicate bidding strategies but it would avoid price increases.
- qsort 6y agoDoesn't that defeat the purpose of the auction in the first place? That would simply become "the ticket goes to whoever writes the largest number on this piece of paper", right? I believe to reach your intended goal (i.e. the seller doesn't want to profit from the auction), you would have to redistribute the price increase among all participants. A way to do this would be as follows (needless to say, completely unpractical fantasy land experiment, I'm only doing this for the sake of argument): - Have people freely register. Let's say you have M tickets, N people registered, the interesting case is when N >> M. - Assign to each registered participant M/N of a ticket (assume tickets are infinitely divisible), and collect from them M/N * P where P is the intended price of a single ticket. - Have people trade fractions of tickets. The seller collects exactly M * P, and under usual assumptions the price of a ticket would converge to its 'true' value.
- ginko 6y ago> Doesn't that defeat the purpose of the auction in the first place? That would simply become "the ticket goes to whoever writes the largest number on this piece of paper", right? People who are bidding more will still pay more. The main weirdness introduced by that approach is that low bidders that win a ticket may get more money back than they paid.
- paulcole 6y agoI thought a Vicrey-Clarke-Groves auction could be undermined by bidder collusion and in particular in some circumstances by a single bidder making multiple bids under different names. Isn’t that exactly what scalping groups would do?
- qsort 6y agoIt can be undermined by collusion, but not if a sufficiently large portion of the bidders is actually honest like, presumably, is the case here. I'm not sure how a single bidder making multiple bids under different names would impact the math, but intuitively I'd say under the same assumption as above the system should hold: if I make N bets out of M with N << M, the effect should be small enough that the guarantees still (broadly) apply. I could be wrong here, feel free to correct me if you know better.
- paulcole 6y ago> if a sufficiently large portion of the bidders is actually honest like, presumably, is the case here. I’m not sure why you think this is the case here? If you create a system that can be gamed by a large portion of the bidders being dishonest, a large portion of the bidders will become dishonest.
- qsort 6y agoI suppose, but how realistic that really is on a scale this large? Wouldn't it be just a giant prisoner's dilemma? Unless almost all parties collude, it's still optimal to bid truthfully.
- paulcole 6y agoIf a system for selling tickets has a weak point, it will be found and exploited by scalpers. That's kind of the whole point of the original article. Every "solution" thrown out by well-meaning third parties is either exploitable by scalpers, makes the experience significantly worse for legitimate buyers, or just shifts which legitimate buyers are able to make a purchase (i.e. I didn't get to buy a ticket but you did. This solution would let me buy a ticket but wouldn't let you buy one).
