The logic is that a country like Greece needs devaluation to enhance its competitiveness, but that leaving the euro would pose major problems. The alternative would be to cut nominal wages (“internal” devaluation), which is hard to do (though it has been achieved in Latvia and Ireland).
另一个方案是提供中央预算补助，以减少欧盟经济挑战最严峻国家的就业税。该方案的逻辑是，向希腊这样的国家需要贬值来增强竞争力，但脱离欧元区会引起严重的问题。替代方案是削减名义工资（“内部”贬值），而这很难办到（尽管拉脱维亚和爱尔兰做到了）。
