Graham occupies a singular position in the history of the theory of international trade. He oppose to the neoclassical theory since John S. Mill, which is based on the reciprocal demand. He claimed that the neoclassical approach contains “the vital defects” (Graham 1932 The Theory of International Values, Quarterly Journal of Economics, 46(4): 581-316.) I wonder if there are recent studies on F. D. Fraham’s theory of international values.
