The Best Advice Fama Got
Here.
With formal statistics, you say something -- a hypothesis -- and then you test it. Harry always said that your criterion should be not whether or not you can reject or accept the hypothesis, but what you can learn from the data. The best thing you can do is use the data to enhance your description of the world. That has been the guiding light of my research. You should use market data to understand markets better, not to say this or that hypothesis is literally true or false. No model is ever strictly true. The real criterion should be: Do I know more about markets when I'm finished than I did when I started? Harry's lesson is one that I've passed on to my students over the 49 years that I've been a teacher.

A Letter to The Queen
Queen asked a question when she visited London School of Economics: why had nobody noticed that the credit crunch was on its way? The British Academy wrote a letter to answer the question later on. On paragraph caught my eyes:
All this exposed the difficulties of slowing the progression of such developments in the presence of a general ‘feel-good’ factor. Households benefited from low unemployment, cheap consumer goods and ready credit. Businesses benefited from lower borrowing costs. Bankers ere earning bumper bonuses and expanding their business around the world. The government benefited from high tax revenues enabling them to increase public spending on schools and hospitals. This was bound to create a psychology of denial. It was a cycle fuelled, in significant measure, not by virtue but by delusion.

Bernamke's Commencement Address
Bernake's speech at the 2009 Commencement of the Boston College School of Law, quite a soft and personal speech.
He mentioned a good quote from John Lennon: "Life is what happens to you while you are busy making other plans."

What Does Your Credit-Card Company Know About You?
A very interesting article about credit card business and its use of human psychology. It also provides some interesting example of correlation, for example:
Less-likely default cardholder: buy felt-pad, visit dentist, getting married, having a child.
More-likely default cardholder: buy chrome-skull, go to bar, pawnshop, marriage therapy.
