The 'paradox' of F. Graham (1890-1949): a study in the theory of international trade

The aim of this paper is to investigate the origins of the protection argument based on increasing and decreasing returns to scale. The development of this theoretical framework is outlined in order to argue that F. Graham's demonstration consists of a synthesis of previous work. We then discuss the debate that took place in the 1930s, which ended with the rejection of Graham's argument as being a paradox or a theoretical curiosity.
