Raghuram Rajan on Economics crisis

 He writes in his blog: 
  • these expectations could have been distorted by ideology – it is hard to get into the past minds of economists. But there is a better reason to be skeptical of explanations relying on ideology. As a group, neither behavioral economists, who think that market efficiency is a joke, nor progressive economists, who distrust free markets, predicted the crisis. 

  • Like medicine, economics has become highly compartmentalized – macroeconomists typically do not pay attention to what financial economists or real-estate economists study, and vice versa. Yet, in order to see the crisis coming, you had to know something about each of these areas, just like it takes a good general practitioner to recognize an exotic disease. Because the profession rewards only careful, well-supported, but necessarily narrow analysis, few economists try to span sub-fields.
