Paul Krugman shows us the three epochs of non boring banking since the 1930's, then uber historian Kevin O'Rouke posts the original article Krugman's piece was based upon, then the baseline scenario produce this graph, and I blog about the whole thing. Brilliant. 
The paper linked to by Phillipon and Reshef will end up on my modules next semester. It's a good day to be on the internet.
Any more responses to my question:
What is the point of the economy?
