edit: "not even remotely an economist" I mean as a compliment, I read his Prospect Theory papers and hold him in high regard. He is a great scientist and psychologist, who did not ever study what is called economic theory- so not an economist.
The Nobel "Memorial" prize by the bank of Sweden was awarded to him. Its what he calls himself that I am talking about, not what some Bank in Sweden is calling him.
Btw, says something about Economics as a field that it chose to name its top most award in way it will be confused with the true prizes set up by Nobel himself. Not the case, for example, with Math or others.
