Trade policies and agricultural exports of Sub-Saharan African countries: Some stylized facts and perspectives

Douillet, Mathilde (2012): Trade policies and agricultural exports of Sub-Saharan African countries: Some stylized facts and perspectives.

Abstract

It has long been consensual that limited market demand within poor African countries have hampered economic development of Sub-Saharan Africa and that countries therefore needed to rely on exports markets to spur economic growth. But despite benefiting from preferential agreements, Sub-Saharan African countries have been marginalized from global trade. Indicators of the exports of Sub-Saharan African countries are constructed to reflect their characteristics. Existing trade negotiating options are examined in the current context of agricultural markets. It appears that prospects at the regional level arise as well as at the global level, especially when looking at the opportunities from a policy coherence for development perspective. Regional prospects are even more acute in light of the global economic crisis affecting traditional trade partners.
