Chapter 6 mainly been on the account of industrial countries which hold a share of more than 70 percent of the world exports, while the share in world exports of the developing countries (excluding OPEC) amounts to 15 percent. * Trade among the industrial countries absorbs more than 50 percent of international trade volume, while trade among developing countries (without OPEC) only accounts for about 3 percent of international trade. The main export markets of the developing countries are the industrial countries which absorb about two thirds of their exports. * The expansion of international trade volume has been accompanied by a change in composition. While the share of manufactured good has increased continuously and amounts to about 75 percent by now, the share of primary commodities (agricultural products, fuel and minerals) has decreased. * Primary products account for more than half of the exports of developing countries but less than 20 percent of the exports of the industrial counties. Many developing countries mainly depend on the export of one or two primary commodities. In essence, the structure of international trade of developing countries is characterized by a dependency on exports of primary commodities to industrial countries on the one side, and on imports of manufactured products from the industrial countries. This structure has a number of unfortunate implications. * The world markets for raw products are largely saturated. Therefore, increased production can only be absorbed at decreasing world market prices. Such tendencies are reinforced by new technologies which are less dependent on raw materials. * Due to limited alternatives of export diversification, there is strong competition among the exporters of primary commodities, compounding the tendencies of price decreases. Exports of primary commodities are, in price and volume, largely dependent on the economic situation in the industrial countries. Highly fluctuating prices and volumes in exports stand against a relatively inflexibly demand for imports of industrial products. In the production of primary commodities, the scope to compensate price reductions by increased production efficiency is limited and lower than in the case of industrial production. Exports at low world market prices of primary commodities can only be maintained if wages are kept low. This is possible if a high number of un- and under- employed people (a typical feature of many developing countries) exerts a downward pressure on wage levels. Low export prices go hand in hand with low levels of household incomes. All these factors together are responsible for the unfavourable position of many developing countries in the international trade system. These are the reasons for their declining share in international trade and the worsening terms of trade (see Box 6.7). During the period 1980 to 1992, the relative prices of primary commodities (excluding fuel) decreased by almost 50 percent in relation to the prices of industrial goods (Commodity Terms of Trade). - 245 -
