On Some “New” Interpretations of Ricardo’s Principle of Comparative Advantages
摘要
Different theories of international trade have originated from Chapter VII “On Foreign Trade” of Ricardo’s Principles and particularly from the interpretation of his numerical example of the gains from trade. In this paper a relatively new interpretation of such example and the resulting implications will be assessed in the light of Sraffa’s writings (1930, 1951) and of the so-called Neo-Ricardian approach applied to the theory of foreign trade. In particular, it will be reconsidered i) the analogy between the choice of international specialization and the choice of techniques, ii) the conditions under which absolute cost advantages prevail over comparative advantages and affect the pattern of international trade and the delocalization of the national industries.
