Mervyn King interview: We prevented a Great Depression... but people have the right to be angry, 4 March 2011, The Telegraph.
(Mervyn King was an academic for 20 years before joining the Bank of England, Wikipedia).
...He loved Cambridge, but economics was too much “harking back” to Keynes. It was in postgraduate work at Harvard that he “learnt that economics could be a serious discipline”. Being a bright young man, he gave “excessive weight” to economic models. “You feel, 'My models will make a big difference.’ As I get older, I give more weight to history...Maths and models should be “aids to thinking, not substitutes for it”
