RBI governor Mr Subbarao in a speech recently on inflation said: "By far the most important statistic for the Reserve Bank is inflation which h as traditionally suffered from me as urement problems. I must admit that even at a personal level, I do not know how to interpret inflation. Twenty years ago, when I had a thick mop of hair, I used to pay `25 for a haircut. Ten years ago, after my hair started thinning, I w as paying `50 for a haircut. And now, when I have virtually no hair left, I am paying `150 for a hair cut. I struggle to determine how much of that is inflation and how much is the premium I pay the barber for the privilege of cutting the Governor's non-existent hair."
