Ever since the independence of the central bank, these levels of seigniorage dropped and became constant, at around 1-2% of the GDP. Also, we computed the potential gains due to euro adoption. We showed that as Romania converge with the rest of the Eurozone its seigniorage potential gains from euro adoption drops. Becaus...
