a.in an auction, potential buyers compete for a good by submitting bids. adam compared ebay auctions in which the same good was sold. he founf that,on average, the larger the number of bidders, the higher the sales price. for example, in two auctions of identical ipods, the one with the lrger number of bidders brought a higher selling price. according to adam, this explain why smart sellers on ebay set absurdly low opening prices(the lowest price that the seller will accept), such as 1 cent for a new ipod. use the concepts of consumer and producer surplus to explain adam's reasoning.
