Inter-industry trade based on comparative or complementary advantage takes place between dissimilar economies whilst intra-industry trade based on absolute or competitive advantage characterizes similar economies. The bulk of North-South trade is of the former type(12). Even much manufactured export from the South is of standard products based on established technologies. Whereas equalized incomes drive the pattern of trade within the North, it is the pattern of specialization and trade that supports non-equalization of factor prices between North and South: primary producers are poor countries and rich countries are industrialized ones. In fact, the absolute difference between average wages in the North and the South has been growing ever larger for close to two centuries. Hence, North-South inequality (in the sense of absolute differences) must be understood in terms of uneven development i.e., dynamic factors making for persistently or even progressively different endowments. _________________________ 12. According to Hamilton and Winters (1992) 70 per cent of the variation in trade flows among a sample of 76 countries was explained by variables measuring national 'proximity' such as incomes rather than variables measuring national differences, a reflection of the large share of North-North trade. But exports from the South are primarily to the dissimilar North Тази констатация, която, надявам се, няма да оспориш, е в изследване на МОТ (ILO - INTERNATIONAL LABOUR ORGANIZATION) Аз съм на мнене, че фактически много малко се е променило в колониалните отношения в последното столетие.
