[1] John C. Harsanyi (1920-2000) was a Hungarian economist who introduced a game transformation turning a game of incomplete information (where some or all players are not aware of some of the relevant game’s features) into a much more manageable game of imperfect information (Harsanyi 1967, 1968a,1968b). A transformed game is denoted Bayesian game, one where each player is assigned by Nature a set of characteristics, which define their type in accordance to a probability distribution known to everyone. By calculating the outcome of this game using notions of Bayesian probability, makes possible to calculate a Nash equilibrium of the game, thus defined Bayesian Nash equilibrium.
