Not sure it's really about information.
It is. Absolutely. Except it's the other way around.
As eBay gives people a source of historical prices, the market becomes more efficient.
Really? Where? Could you show me trend for, I don't know, Blizzard 1260? There were dozen of sales in the last year at least, perhaps more, on eBay. Where are they? Sure, you could use Google and some other tricks and discover some of these, but this is really hard work. eBay is
absolutely awful WRT past deals for rare items. It works adequately for abundant stuff (you could see many offers, sellers are competing and buyers could choose and pick) but for rare items (and we are dealing with rare items here) deals go from extremely low to extremely high - and of course extremely low deals happen when someone takes stuff out of their closet and wants to sell it. With no guidance s/he sets price really low... and it's quickly snatched by avid "collector" who will sell it later for 10x more.
Sorry to go on, but I am sick of the tripe spouted on these forums by free marketeers [not aimed at you at all] who get very righteous about market prices being right. There's nothing right or wrong or moral or immoral about it, the economics is purely descriptive of whast happens, and the market price is just the market price,.
Why "not aimed at you at all"? When someone looks on the big painting named
WHEN MARKETS SHOULD FAIL and start explaining that markets are always right the first question to ask is: how about doing some homework?
Yes market says prices "right"… when there's
perfect competition, that is. And
perfect competition means two things:
1. There are
no participants large enough to have the market power to set the price of a homogeneous product.
2. Participants have perfect knowledge about deals which happen on said market.
Now, compare the AmiBay (where deals happen in the open and where hoarders are punished) to eBay (where past deals are hard to find and where hoarders are thriving). Which one looks like a free market to you?
In a sense Grimakis is right: eventually AmiBay will succumb to the forces which destroy all the markets (it's well-known facts that unregulated markets tend to self-destruct… that's why there are
competion law, after all), but this will not be triumph of the market. Quite the opposite. Sales on antiques are the opposite of a free market—the textbook case of market failure, that's why "big boys" are using them to store their wealth: when there are no market and shortage of offers prices are only going up. And, sadly, Amiga hardware slowly but surely moves into that category.
Sorry to say it, but there are a lot of people out there who collect computers. The demand is higher than when most people entered this hobby. Some people have more disposable income, their willingness to pay is higher, etc.
Exactly. More [potential] buyers, less stuff on the market (old computers die, you know), less information - perfect recipe for the market failure. Which will eventually happen, it's only natural - despite all the attempts of AmiBay to try to postpone it. But hey, if we'll manage to postpone destruction of market by a few years… that'll be good thing, isn't it?
