The document discusses the adoption of a common currency in Europe and its advantages. It outlines the history of the euro, from the Werner Plan in 1970 to the establishment of the European Monetary System (EMS) in 1979. The EMS aimed to stabilize exchange rates between European currencies. This eventually led to the creation of the euro in 1999 to further economic integration and remove exchange rate uncertainty within the EU. Adopting a common currency has benefits like reducing transaction costs and optimizing allocation of resources across borders.
