Yet Another Proof of the Existence of a Competitive Equilibrium Yet Another Proof of the Existence of a Competitive Equilibrium

This note provides a new proof of the existence of a walrasian equilibrium in pure exchange economies under quite standard and general assumptions. The proof still employs a fixed point argument, however, it is shorter and simpler than those currently available for the case considered.
