Economy of Referential Preferences A new mathematical approach for choice theory and general equilibrium

Teycir GOUCHA
University of Tunis

Abstract. In this paper we introduce basic notions of a new economic model where preference relations on commodities set are represented by a group action on Euclidean space instead of utility function. Conditions that ensure the existence of individual demand function and a general equilibrium in the setting of exchange economy are examined.

Keywords: preference relations; group theory; general equilibrium.
