A New Approach for General Equilibrium with Discontinuous Excess Demand Function

Traditional ways to prove the existence of general equilibrium have to entail a common condition that the excess demand function must be continuous. This paper presents a new approach to change it. The technique used in this paper is that we tackle general equilibrium problem, which in fact is a static nonlinear programming problem, with dynamic programming. By this technique, it is strictly proven that general equilibrium with discontinuous excess demand function still exists
