M OTIVATION Why Bilateral trade Flows are Low within Sub- Saharan Africa (SSA)?

L ITERATURE  Hanink and Owusu (1998)  Used trade intensity index (TII)  Find that ECOWAS has failed to promote trade  Alemayehu and Haile (2008)  Regional grouping has insignificant effects on bilateral trade flows in SSA.  Reasons: poor private participation, compensation issue.  Faezeh and Pritchett (2009)  Trade flows are low within SSA  Gravity prediction similar to actual trade  Piet and Wheeler (2010)  Transport infrastructure and border restrictions are main reasons for lower trade rate in SSA

C ONTRIBUTIONS Trade evaluation based on imperfect specialization in production Show that comparative advantages matter in stimulating trade SSA countries exhibit similar endowments Products are not differentiated in the region

U NDERLYING TRADE T HEORIES  Heckscher-Ohlin Theory: Heckscher (1919) and Ohlin (1933)  Predicts high trade for large differences in factor endowment ratios.  Increasing return to scale theory: Krugman (1979, 1980)  Predicts intensive trade between industries producing different varieties of a product.  The love of varieties creates demand across countries.

M ETHODOLOGIES

D ATA  118 countries across the world grouped into 5 regions: Asia, Europe and North America, Latin America and Caribbean, Middle East and North Africa, and Sub-Saharan Africa.  Panel from 1997 to 2007  Data on bilateral imports is extracted from the IMF-DOT  Data on Real GDP, Investment Share, Real GDP per worker, and population are taken from the Penn World Tables (last version- 6.3)  Data on trade factor dummies can be found at  Capital stock and labor force data are from the World Bank’s World Development indicator (WDI) database  The Grubel Llyod is calculated using Uncomtrade data at 3-digit.

R ESULTS

C ONCLUDING REMARKS  Bilateral trade flows are low within SSA compare to that of other regions due to:  Lack of comparative advantage in production across countries in SSA  Similar endowments in factors of production across countries within SSA  Homogeneity of traded goods  Less product differentiation

S UGGESTIONS  SSA countries might want to increase efforts towards accessing developed markets  Gain the “know-how” from interacting with mature markets  Benefit from their comparative advantage over industrialized countries  Use new technologies for industrialization and differentiate their products in many varieties.
