Calibrating Informal Cross-Border Trade in Southern Africa

The study demonstrates that informal cross-border  is a complex
phenomenon and not uniform across the region, or even through border
posts of the same country. However, the overall volume of trade, duties
paid and VAT foregone, as well as the types of goods and where they are
produced, indicate that this sector of regional trade should be given 
much greater attention and support by governments of the region as well
as regional organizations such as the Common Market for Eastern and
Southern Africa (COMESA), SADC and the Southern African Customs Union
(SACU).
