My graduate study was interrupted, like that of many others, by World War II.

In 1963 and later papers, I pointed out that the special market characteristics of medical care and medical insurance could be explained by reference to differences in information among the parties involved.

My assignment was exclusively in the research field, and my first published paper, On the Optimal Use of Winds for Flight Planning, was the outgrowth of that work.

My research, even before 1972, moved in directions beyond those cited for the Nobel Memorial Prize. Most of it, in one way or another, deals with information as an economic variable, both as to its production and as to its use.

My undergraduate education, at the City College in New York, was made possible only by the existence of that excellent free institution and the financial sacrifices of my parents.
