I just had an idea.  One of the things pushing up
e-bay prices
 is the publication of the high bids of past auctions.  The logic
 for sellers is something like, since the previous one sold for
 this much, I should expect at least as much for this one. 
  What if we kept (and publicized) a record of asking
prices for
 the things that did *not* sell?  Maybe buyers would look at that,
 and use similar logic to avoid bidding any higher than that? 
There are still to things to consider
a) the buyer - if the buyer is willing to pay, nobody can stop him
b) the seller - if you present a seller 10 low prices and 1 high, he
   still goes for the higher one - man is an optimistic creature :9
