Lol Economists.
Remember these two? Myron Scholes and Robert Merto. They won a Nobel price on 1994 based on some derivatives model idea they had then started a hedge fund based on that model. They failed miserably and lost billions.
LTCM? Their model is still being used today. I doubt that they deserved a Nobel prize for it though, the great 2008 crash had a lot to do with the model they created
