The Economics of Auctions
What an Auction Is
An auction is a way of setting prices by asking buyers to compete, useful when a seller doesn't know what something is worth.
In an auction, bidders compete, and the winner pays according to set rules. The seller uses competition to discover the price.
Why auctions
They work when goods are unique, prices are uncertain or the seller wants the highest price.
Everyday examples
Art, used cars, spectrum, coal mines, government bonds and online ad slots.
Reserve price
The minimum the seller will accept; below it, the item goes unsold.
A painting
A rare artwork is sold to the highest bidder at a famous auction house.
Assuming auctions are only for antiques
Governments and firms use them for huge deals.
