In this paper, a use of s-quasimonotonicity in an economics model is presented. We introduce a strong version of Wald's Axiom of excess demand functions. Under some assumptions, Z satisfies the strong version of Wald's Axiom iff -Z is a s-quasimonotone function. Some properties on the measure of the strong version of Wald's Axiom of excess demand functions are also presented.
