Notes on the fifth summer institute for the preservation of the study of the history of economics

I was invited by Sandra Peart and David Levy to take part in the Summer Institute held from 26 to 30 July 2004 at George Mason University. After some discussion I agreed to give two lectures, on my project on the use of the concept of the invisible hand and on the theory of economic policy of Lionel Robbins and Friedrich Hayek, and to participate in a public “conversation” with James M. Buchanan before the same group. Subsequently, I accepted Buchanan's invitation to have a videotaped private interview by him.
