"Tobin asked me to come and talk at Yale in 1977, and I was there for a couple of days. He was really nice in a personal way. He made it clear that he respected my work as a professional, so I didn't feel my professional standing was at risk. When I got there he gave me a nice introduction. It wasn't a question of whether I was a competent economist or not; there was nothing personal involved. These guys, however, had lots of disagreements and criticisms. I'd been thinking along these lines for many years, so I thought I did a pretty good job of taking care of the questions, but I don't know how it looked from the other side. It left me with a feeling of being way ahead of the game. It was an exciting feeling."
