impact on export earnings and incomes, given the declining trend of prices <strong>for</strong> these<br />

commodities.<br />

Traditional exports of all <strong>African</strong> countries, except <strong>for</strong> South Africa and Malawi,<br />

experienced negative global demand growth during 1995-99, and in some cases the<br />

declines were dramatic (Ng and Yeats, 2000). Empirical evidence suggests that the<br />

income elasticities of <strong>African</strong> traditional exports are well below unity. As such, continued<br />

reliance on traditional exports will significantly extend Africa’s marginalization in world<br />

trade. This trend could be reversed, or the rate of marginalization slowed, if Africa<br />

achieved major competitive gains <strong>for</strong> the traditional export commodities to compensate<br />

<strong>for</strong> their relatively low demand growth. However, a recent analysis of Africa’s supply<br />

capacities found no evidence that these competitive gains were occurring (Ng and Yeats,<br />

2002).<br />

a. Terms of Trade of Traditional Agricultural Exports<br />

Fluctuations in the relative prices of coffee and cocoa are a major cause of the<br />

poor per<strong>for</strong>mance of traditional exports. While the overall trend during the past two<br />

decades was downward, there were ephemeral surges in commodity prices and terms of<br />

trade. World commodity markets experienced a major price cycle starting in 1993. The<br />

upward phase of this price cycle lasted two to five years depending on the commodity<br />

(UNCTAD, 2001). The commodity terms of trade, calculated on the basis of world prices<br />

of broad categories of primary commodities (agricultural raw materials, food, tropical<br />

beverages, vegetable oilseeds and oils, and minerals and metals), as well as prices of<br />

<strong>African</strong> coffee, cocoa, cotton, and copper exports, vis-à-vis unit export prices of<br />

manufactures of developed countries reflect a more volatile pattern than the overall terms<br />

of trade <strong>for</strong> Africa.<br />

b. Trade Restrictions on Traditional Exports<br />

While Africa generally maintained its ability to compete with other <strong>for</strong>eign<br />

suppliers of most traditional goods, a related question concerns the importance of<br />

government-imposed trade restrictions, which place Africa in competitive disadvantage.<br />
