Perhaps more notable is that both the US and UK economies have cast considerable doubt on Krugman’s oft-repeated view that a robust recovery would require further fiscal stimulus, a position that he maintained at least until 2013. The post-2010 recoveries in both countries came despite significant cuts in the structural (cyclically adjusted) budget deficit, suggesting that both recoveries occurred in the face of fiscal contraction.
也许更加引人关注的是美国和英国经济严重质疑了克鲁格曼时常挂在嘴边的观点——强健复苏需要更多财政刺激。至少在2013年之前，他一直持有这一立场。2010年后的英国和美国复苏是在结构性（经周期调整的）预算赤字大幅削减的情况下实现的，这表明两国的复苏都发生于财政收缩环境中。据IMF估计，英国结构性预算赤字从2010年占潜在GDP的8.4%削减至2014年的4.1%，而美国同期从9.1%削减至4%。
