Incentive policies and export performance in sub-Saharan Africa
计量分析表明撒哈拉以南非洲的出口（尤其是农产品出口）对价格激励有反应，且市场化国家比干预主义国家获得了更大的出口市场份额。
The paper presents the results of an econometric investigation which shows that exports in general, and agricultural exports in particular, are responsive to price incentives in sub- Saharan Africa. It is further shown that, within sub-Saharan Africa, market-oriented countries generally gained, and interventionist countries lost, export market shares. The differences in export performance are even greater if comparisons are made between private market economies and étatist countries in a three-fold classification scheme that puts some countries in an intermediate category.
