The inverse of the relationship, y = f (x), is the graphical representation of Marshall’s derived demand curve for the selected factor of production.
A low elasticity of derived demand encourages supply restrictions.
According to him, in order for elasticity of derived demand to be low, ‘It is “important to be unimportant” only when the consumer can substitute more easily than the entrepreneur’.
