My main graduate training was received at the University of Chicago from which I received the Ph.D. in 1938.

The main insight learned from interdisciplinary studies is the return to specialization

It was in the 1960s that I began the detailed study of public regulation.

I started working and publishing in price theory by 1938.

And yet I would not freely exchange my science for those of my fellow laureates. They are forever confined in their professional discussions to the small numbers of their fellow scientists.

My interests were aroused, and my faith in the cliches of the subject destroyed, as so often with other subjects, by the discussions with my friend, Aaron Director.

The Chicago Economics Department was in intellectual ferment, although the central issues of the 1930s were very different from those in later times. I had never before encountered minds of that quality at close quarters and they influenced me strongly.
