Border effect (Ofer Abarbanel online library)

Border effects refer to asymmetries in trade patterns between cities and regions of different countries that share a national border and those that are located in the same country. Usually, trade volume is much lesser between the former cities and regions.[1]

Economic integration (as in the EU) may be a solution to overcome these effects. A 2017 meta-analysis of 1,271 estimates of the border effect finds that borders reduce trade by one third. [2]
