Populists in Europe are contesting the perceived benefits of economic integration between countries. This column uses data on trade frictions to estimate the long-run impact of trade frictions on GDP if countries in Europe were to be more or less integrated. Negative between-country impacts, such as from Brexit or an EU collapse, imply a GDP reduction of between 1-3%. The potential trade benefits of a ‘United States of Europe’, on the other hand, may be an order of magnitude greater for its members.
