Common currency, common identity? The impact of the Euro introduction on European identity

Does European state building go hand in hand with European nation building? This article engages with the scholarly debate on the dynamic relationship between the construction of supranational political institutions that exert key functions of sovereignty and collective identities by investigating the extent to which the adoption of the Euro as a currency is associated with a decrease in the share of Europeans who identify exclusively with their nation and not with the European Union. In detail, by using a dynamic panel-data model on 26 European Union countries in the post-Maastricht period (1996–2017), our results show that the Euro has fostered European identity, leading to a small but significant decrease (-3%) in the share of Europeans with exclusive national identity.
