Adopting the euro does not work without political integration
摘要
A new empirical exercise for dealing the effects of monetary unions on welfare is developed. The estimates of the effects of adopting the euro using a sample of 216 countries for the 1960–2021 period apply a novel multiple-period differences-in-differences approach. They show a significant and robust negative effect on economic growth of adopting the euro, mainly for the countries with the highest income inequality.
