Abstract

We are interested in proving an equilibrium existence result in a general equilibrium model with incomplete nominal asset markets. When we relax the assumption of strict positivity of initial endowments, then, as it is the case for every general equilibrium existence problem, we need to introduce survival, and irreducibility assumptions, whose formulation is the object of this paper. The financial economy that we consider is a two period exchange economy where agents' preferences on their consumption sets may be non-ordered and do not satisfy monotonicity.
