“So far, twenty-two people have received the Nobel award in economics. Not one of them has been female—so, to judge only from the past, the most important thing to do if you want to be a Nobel laureate is to be male. I hasten to add that the absence of females is not, I believe, attributable to male chauvinist bias on the part of the Swedish Nobel Committee. I believe that the economics profession as a whole would have been nearly unanimous that, during the period in question, only one female candidate met the relevant standards—the English economist Joan Robinson, who has since died. The failure of the Nobel Committee to award her a prize may well have reflected bias but not sex bias. The economists here will understand what I am talking about. … A second requirement is to be a U. S. citizen. Twelve of the twenty-two recipients of the Nobel Prize were from the United States, four from the United Kingdom, two from Sweden, and one each from four other countries. … Of the twelve Americans who have won the Nobel Prize in economics, nine either studied or taught at the University of Chicago. So the next lesson is to go to the University of Chicago.”
