Movements of relative agricultural prices in sub-Saharan Africa
研究了1973年至1999-95年间20个撒哈拉以南非洲国家农产品相对价格的变动，比较了农业部门净易货贸易条件与国际贸易条件，发现传统观点认为非洲政策偏向城市、损害农民利益的说法值得商榷，且近年农业市场自由化并未给农民带来好处。
Movements of relative agricultural prices in 20 countries in sub-Saharan Africa between 1973 and 1999-95 are investigated. Changes in the net barter terms of trade of the agricultural sector are compared with international terms of trade movements. Movements in prices received by cocoa, coffee, cotton and tea farmers are compared with unit export prices and with indicators of production costs. World price movements for the same commodities are compared with unit export prices of major exporting countries. A similar analysis is undertaken for cereals, where producer prices are compared with unit import prices and with cost indicators. Possible factors that affect these relative price movements are discussed with special emphasis on the role of alternative policy regimes. Empirical findings suggest that conventional views on the anti-farmer bias of African policies till the 1980s are questionable and the recent liberalisation of agricultural markets in Africa have not generated farmer-friendly outcomes.
