Definition of



relationship of values the convex shape of a curve. The theory is that if points in a set are connected and the line between any two points is included in the set, then the set is convex. In economics, this corresponds to diminishing marginal utility. In finance it can represent a convex curve in the price yield relationship of a bond or any non-linear price function, for example, that of an option.
