Henry Ford made a lot of money making cars at one time, but that was a small advantage to him compared to the benefit to millions of people who for the first time in their lives were emancipated from common public carriers and could live where they wanted, move at the hours they wanted, to the places they wanted. Ford collected a billion bucks, but that was peanuts compared to the benefits.

In the 1950s, I proposed the survivor method of determining the efficient sizes of enterprises, and worked on delivered price systems, vertical integration, and similar topics.

The delicate and intricate pattern of competition and cooperation in the economic behavior of the hundreds of thousands of citizens of Stockholm offers a challenge to the economist that is perhaps as complex as the challenges of the physicist and the chemist.

Adam Smith had one overwhelmingly important triumph: he put into the center of economics the systematic analysis of the behavior of individuals pursuing their self-interest under conditions of competition.

There is only one social science and we are its practitioners

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.
