“Well, I certainly was not going to study physics, and I knew I was not going to study biology, but I could have become a sociologist or an anthropologist. However, I found sociology a little soft. I think that somewhere in my mind, I probably already had the notion – which turned out to be right – that if I was going to be a social scientist of some kind, I would like a rigorous social science. The analytical aspect of economics already appealed to me. That must have been so. It was not really a matter of chance. But if my wife had said ‘oh, no, economics was terribly boring’, I would probably have found something else to do.”
