The erection of physical border protection structures have a stronger negative impact on trade flows that other geographical variables. So argue Vetonatus Kamwela, Dr Binyam Demena and Dr Peter van Bergeijk in their latest article published in Applied Economics.

In 'The return of the border walls', the authors consider the proliferation of border wall and fences since the early 2000s.

Examining data from over 100 countries, they find that although the immediate impact of erecting a wall or fence is insignificant, over a longer period the constructions account for a roughly two-third reduction in bilateral trade between the two sides of the border.
