A recent report released by the World Economic Forum  says that border administration and infrastructure are the biggest problem to international trade.

Reducing supply chain barriers to trade could increase GDP by nearly 5% and trade by 15%

If every country improved just two key supply chain barriers – border administration and transport and communications infrastructure and related services – even halfway to the world’s best practices, global GDP could increase by US$ 2.6 trillion (4.7%) and exports by US$ 1.6 trillion (14.5%). For comparison, completely eliminating tariffs could increase global GDP by US$ 0.4 trillion (0.7%) and exports by US$ 1.1 trillion (10.1%). The estimates of the impact of barrier reduction are conservative; they reflect improvements in only two of four major supply chain categories.

Why is lowering barriers so effective? The reason is that it eliminates resource waste, whereas abolishing tariffs mainly reallocates resources. Moreover, the gains from reducing barriers are more evenly distributed among nations than the gains from eliminating tariffs.

Of course, reducing supply chain barriers requires investment, while tariff reductions require only the stroke of a pen. However, many barriers can be traced to regulation. Detailed analysis can enable policymakers to prioritize the investments that are most critical and cost-efficient.

Tariffs are of course very important (see figure).

But removing supply-chain barriers would be even more successful, especially  in Africa (click on the image to enlarge).
