Book excerpt: Policies designed to address the regional adding- up problem in Sub-Saharan Africa -- such as a region- optimal export tax -- generate unequal benefits among countries. Further, few countries in Sub-Saharan Africa have sufficient market power to influence commodity prices in the long run. Export taxes may prove beneficial for some countries but, at certain levels, transfer resources from smallholders to government with limited welfare gains.
