What is game auction?
A game-theoretic auction model is a mathematical game represented by a set of players, a set of actions (strategies) available to each player, and a payoff vector corresponding to each combination of strategies. Generally, the players are the buyer(s) and the seller(s).
How is game theory used in auctions?
In the game theoretic approach, all players maximize their own expected profit, or, more generally, their expected utility, while, at the same time, this is common knowledge to all auction participants. A private value auction postulates that each bidder knows how much he/she values the auctioned object.
What is the purpose of an auction?
An auction is a sales event wherein potential buyers place competitive bids on assets or services either in an open or closed format. Auctions are popular because buyers and sellers believe they will get a good deal buying or selling assets.
How do you play the auction game?
To make a bid, each player selects a SINGLE card from the money he has left and places it face-down (hidden from the other player) on the table. When both players have done so, they reveal their cards simultaneously. The player who bid the most wins the card and must pay the money card he had placed.
What is the most efficient type of auction?

How does game theory apply to non binding auctions?
In non-binding auctions, including online non-binding auctions, it’s easier for the auctioneer to submit a fake bid to increase the perceived competition and drive prices up. The degree to which those involved in negotiations really behave rationally – a prerequisite for the application of game theory – is an especially interesting question.
How are auctions used in the real world?
Auctions are generally used by sellers in situations where they do not have a good estimate of the buyers’ true values for an item, and where buyers do not know each other’s values. In this case, as we will see, some of the main auction formats can be used to elicit bids from buyers that reveal these values.
