I have a colleague who told me some time back that he had identified a strong leading indicator of economists who think they are on the short list for winning the prize: getting a haircut the week before the Nobel is announced. He claims to have many data points supporting his theory.
The economics Nobel is announced Monday. If I’m not mistaken, this very colleague is sporting a snazzy new haircut.
