One is that economists lacked models that could account for the behavior that led to the crisis. Another is that economists were blinkered by an ideology according to which a free and unfettered market could do no wrong.
对此其实有几种答案。一是说经济学家缺少相关模型，因此也无法对导致本次危机的行为作出解释。另一种认为经济学家都被无限制自由市场的教条思想蒙住了眼睛，觉得这样的市场是不会出错的。而最后一种逐渐流行的说法则是经济学家都收受了金融系统的好处，于是集体保持沉默。
