Oliver. Hart发表在《华尔街日报》上的文章：认为在金融危机中，经济学家都放弃了自己的原则——选择性干预经济是不好的，这已经是经济学界的共识。但是这一原则现在被大家所抛弃。

"This year will be remembered not just for one of the worst financial crises in American history, but also as the moment when economists abandoned their principles. There used to be a consensus that selective intervention in the economy was bad. In the last 12 months this belief has been shattered."
