Static game of incomplete information:

The game of  inco~nplete  information also called the Bayesian games. Recall that  in  the  game  of complete information the players' payoff functions  are common knowledge. In  contrast,  in a game of incomplete information at  least one player  is uncertain about another player's  payoff  function. Most common example of this kind  of game  is sealed bid  auction, where each player knows her own valuation for the good being  sold but not  the valuation of any other bidder's. We begin  our discussion  of  static game of  incomplete information with normal form representation of Bayesian Nash equilibrium.
