In the second scenario, a two- or three-tiered Europe includes a two-tiered euro, with the weaker countries using a separate “euro-B” currency that can float against the stronger economies’ “euro-A.” This arrangement would hold out the promise to fiscally stressed economies that, if they get their act together, they could rejoin euro-A – and do so more readily than they could from their own currency.
第二个方向是出现一个两到三个层次的欧洲，使用两层次的欧元设计，疲软国家使用单独的“B欧元”货币，其对坚挺国所使用的“A欧元”汇率可以浮动。这一安排可以让财政不堪重负的国家维持承诺，如果它们采取一致行动，可以重新回到A欧元集团——比它们使用自己的货币要容易得多。
