摘要: Abstract In this paper we consider a competitive economic equilibrium problem where preferences of consumers are expressed by means binary relation. The aim is to find suitable quasi-variational inequality which characterizes the equilibria and, using tools variational theory, study such equilibria. novelty consists in an approach without need representing consumer's utility function.
