In 2006, I was requested to contribute to an analysis of the impact of transportation costs on trade competitiveness in Sub-Saharan Africa (SSA). Back then, I was working as an intern in the World Bank (WB) Africa Transport Unit with Gaël Raballand, a senior WB economist, to conduct a cost/benefit analysis (CBA) of a US$ 200 million regional transport project in Central Africa (Cameroon, Central African Republic and Chad). The project included investments in road and rail infrastructure, in border posts, and few innovative soft components to facilitate trade movements in the region (1). Six years later, the project is still on and has been extended three times to reach a total approved financing of more than half a billion dollars to date.
