Giochi in forma decisionale: definizioni e applicazioni

In this chapter, we define and apply a form of two–player game called decision–form game. Decision form games were introduced for the first time in 2007 by David Carfì. A two–player decision–form game consists in a pair of decision rules, representing the rationality of each player respectively. We develop the basic features of this type of games, showing that this form of game generalizes the normal–form. Indeed, we see how to associate a decision form game with a normal form game. In the chapter, we show examples of decision–form games not–deriving, a priori, from normal–form games. We observe that we can associate several decision–form games with a normal–form game, each representing a possible decision behaviour of players. The classic best–response behaviour is only one of these possible behaviours.
