In other political unions, cohesion is maintained through a strong common identity, but often also through permanent fiscal transfers between richer and poorer regions that even out incomes ex post. In the euro area, such one-way transfers between countries are not foreseen (transfers do exist as part of the EU’s cohesion policy, but are limited in size and are primarily designed to support the “catching-up” process in lower income countries or regions).
在其他政治联盟，凝聚力通过强大的共同身份维持，但往往也通过富裕地区和贫穷地区持久的财政转移从而在事后实现收入平均来维持。在欧元区，这一国家间的单向转移在可预见的未来不会存在（欧盟团结政策中确实有关于转移支付的内容，但规模有限制，并主要是为了支持低收入国家或地区的“赶超”过程）。这意味着我们需要另辟蹊径确保每个国家都会因为加入欧元区而持续变得更好。
