Global Univalence when Mappings are not Necessarily Continuous
AbstractThis paper proposes a method of establishing the global univalence of a mapping without the
assumption of continuity and the absence of points of inflection. When the functions are not
continuous and the points of inflections are present, the use of a Jacobian to establish univalence
presents some difficulties. The method of establishing univalency, presented in this paper, in turn
generalizes the theorems on the uniqueness of competitive equilibrium and factor price
