4. Decision Making (2) 3. Auctions<br />

While voting binds all agents, auctions are<br />

always deals between 2.<br />

Types of auctions:<br />

first-price open cry: (English auction), as usual.<br />

first-price sealed bid: one bids without<br />

knowing the other bids.<br />

dutch auction: (descending auction) the seller<br />

lowers the price until it is taken.<br />

second-price sealed bid: (Vickrey auction)<br />

Highest bidder wins, but the price is<br />

the second highest bid!
