At a dinner a number of years ago, a visiting central banker asked the BIS to write a paper on the prospects for the oil market. As quick as a flash, Andrew Crockett (then the  2  BIS Review 2/2008  General Manager of the BIS) said he would get our oil department on it immediately.
There was a pause, and then someone asked how many economists were in the oil department. Again quick as a flash, Andrew said “about 40”. And then there was another pause as those at the dinner seemed by their silence to accept this as fact.
