Seemingly, very different values and stowage factors for the goods being exported explain some of the cross-country variation in African freight costs. A third point reflected in Table2 is that average nominal freight rates for African exports are consistently higher, with the exception of the oil exporters, than those on similar goods shipped from other countries. quot; apos; For all sub-Saharan countries combined, ad valorem freight costs are about 20 percent higher on average.... In PAGE 15: ... However, these aggregate figures conceal the true importance of adverse freight rates 9The sub-Saharan totals reported here, and in the subsequent tables, exclude the African oil exporting countries (Angola, Congo, Gabon and Nigeria) since their relative importance in global energy trade may have lead to the development of transport systems and infra-structure that was significantly different from other African countries.
