Some remarks about uniqueness of equilibrium for infinite dimensional economies

Keywords: general equilibrium theory, Mitjushim-Polterovich condition


For economies with infinitely many goods, with two different approaches we obtain sufficient conditions for uniqueness of competitive equilibrium. In the second approach we prove that the Mitjushim-Polterovich condition is a sufficient condition for uniqueness of equilibrium when the consumption space is a positive cone included in a Banach space. We do not suppose separability of the utility function.
