Regional integration arrangements1 have had a long history in sub-Saharan Africa, beginning with the customs union in 1900 between Kenya (then the East African protectorate) and Uganda. Integration has generally been perceived by policymakers to be a highly desirable objective, despite the lack of decisive and concrete actions to achieve positive outcomes. There have indeed been many arguments in support of integration at regional meetings and relatively few against. The consequence is that institutions and protocols for regional integration are available in relative abundance. The integration discussions and efforts have covered such varied areas as trade integration, labor market integration, capital market integration, monetary integration, and so forth. Trade integration has naturally attracted greater attention from policymakers and researchers.
