Third, it was (somewhat naively) believed that the institutions underpinning the euro would improve the overall quality of economic policy, as though Europe-wide policies would automatically be better than national ones. The acid test came in the aftermath of the 2008 global financial crisis: because it overestimated the fiscal dimension of the crisis and underestimated its financial dimension, the eurozone performed worse than the United States and the United Kingdom.
第三，人们（不无天真地）认为作为欧元基础的机构能够改善经济政策的总体质量，好像欧洲整体政策水平天然就比国家政策水平高似的。2008年全球金融危机后，严峻的考验来临了：欧元区高估了危机的财政维度，低估了它的金融维度，因此其表现不如美国和英国。
