It is argued in this paper that there are significant differences between interregional and international trade, mainly because of the existence of increasing returns at a regional level, next to comparative advantages. Consequently, location matters, although interregional trade seems to be lagging GDP growth, most likely as a result of a structurally declining regional specialisation.
