EU-medlemskaps påverkan på bilaterala handelsflöden

Sammanfattning: The different ways countries trade with each other have developed during the years but the purpose, free exchange in goods and services, remains intact. The main idea of trade between countries is that both parties gain from the exchange. The European Union is the world’s biggest trading block, and in the form of a customs union there are mainly two different ways in which it theoretically can affect bilateral trade flows, namely by trade diversion or by trade creation. The purpose of this thesis is to analyze how the European Union affects the bilateral trade flows both within the union, as well as with countries outside of it. In order to examine these effects a quantitative method will be used where a regression analysis is applied based on a gravity model, observing the years 2000–2019. The results indicate a significant positive effect of EU-membership on both trade flows with different member countries, as well as with countries without a membership. The estimations from the different regressions indicate that the bilateral trade flows between member countries increases with around 33%–40%, while bilateral trade flows with countries outside of the union increases with around 3%.
