A couple of questions have been posed regarding the graph I developed for Wallonia’s trade share with Canada. Here are some of my explanations and further thoughts on the issue.
One remark that was made related to the fact that these figures would be biased because Flanders has Antwerp. Antwerp, like Rotterdam, are known for what trade-economists call their “entrepôt” activities. These two cities import lots of goods because of their ports, store them, and then re-export them again to other parts of Europe, i.e. the hinterland, which I indeed allude to in the piece.
This bias is true, but only to some extent. The NBB source that separates regional trade between Flanders and Wallonia on the one hand and Canada on the other presents data at a level where these imports and re-exports of non-residential entities are excluded, i.e. pure transit trade appears to be out.
