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.

There's only one problem that bothers me. And that's something my theorem [ of Impossibility] really doesn't cover. In my theorem I was assuming people vote sincerely. The trouble with methods where you have three or four classes, I think if people vote sincerely they may well be very satisfactory. The problem is the incentive to misrepresent your vote may be high.

I think on the efficiency level, not only the distribution level, capitalism is a flawed system. It probably has the same virtues as Churchill attributed to democracy: It's the worst system except for any other. And I think that's right, but it cannot be thought that some unmitigated belief in free markets is a cure even from the efficiency point of view.

I think one of the things we learned from the physicists and also the theoretical biologists is the idea that when you're dealing with very complex systems you're going to get a large variety of behavior which can be interpreted as hill climbing, but hill climbing with a lot of modifications, hill climbing with big jumps occasionally.

The health care provisions are presumably for individuals. And whoever pays for them, whether it's paid by the individual, state, whatever, the value is an individually based value. It has nothing to do with employment.

The intrinsic social structure, the family structure and so forth, is certainly in a very bad state. And I think that this is showing up in productivity. I think part of the reason, and I can't prove this, we're seeing a decline in some places is the breakup of the family, which is partly the result of an extreme form of individualism.
