In early 2006, when the Ifo indicator foresaw an economic upturn while the German Federal Statistical Office reported meager quarterly GDP growth figures, some commentators scoffed. But when the Office later revised its data upward, it became clear that the Ifo indicator was right.
2006年初，尽管当德国联邦统计局公布了GDP季度的微弱增长，IFO经济景气指数却预见到未来会出现经济复苏，而一些评论家对此嗤之以鼻。但当德国联邦统计局后来将数据上调后，很明显，IFO是正确的。
