Teoría de la utilidad neoclásica: un juego semántico de interacción estratégica

This article suggests that the methodological strength of what is known as the neoclassic utility theory (NCUT) comes from the relationship between the parlor games, typical of formal logic, and the seek and find games which are founded in the modal logic. Through the use of the semantic games we will establish two points: the conditions for the strategic interaction between the neoclassic player, who seeks to construct ideal utility functions, and an opponent who proposes tough counter examples, as well as semantics for the NCUT. In addition, we suggest that expansion of NCUT to other possible worlds does depend on the transformations carried out in the original model-set.
