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.

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.

The Germans, for example, have some kind of compromise between single-member and broader districts. In Israel, you have nothing, you have only a national election. You have no local districts at all. And that's because of the idea that in addition to other ideological differences, locality matters. The question is does the congressman represent his district and the interests of his district? And as I said there's quite a variety of systems the democratic world. The implications need to be examined.

I do sense, as compared with let's say the early '50s, there's somewhat more of a careerism. I don't think it's anything special to economics; it's equally true with physics or biology. A graduate education has become a more career-oriented thing, and part of that is because of the need for funding. In fact, that's a much worse problem in the natural sciences than it is in economics. So you can't even do your work in the natural sciences, particularly, and even to some extent in economics, without funding.

In my [Impossibility] theorem I'm assuming that the information is a ranking. Each voter can say of any two candidates, I prefer this one to this one. So then we have essentially a ranking. It's a list saying this is my first choice. This is my second choice. Each voter, in principle, could be asked to give that entire piece of information. In the ordinary Plurality Voting, say as used in electing Congressmen, we generally only ask for the first choice. But, in principle, we could ask for more choices.

Classic economic theories recognize public goods aspects of one kind or another - the need for economic intervention in, obviously, the supply of infrastructure and of education. We're not supplying that infrastructure at an appropriate rate today. I don't doubt it isn't just money; it's organization and goals and so forth.

When you look at any experimental work not directly related to economics, but trying to test rational behavior in other ways, experiments have conspicuously failed to show rational behavior. Macro evidence certainly suggests deviations from rationality, but I don't want to say the rationality hypothesis is completely wrong. If you have any introspective idea or experimental idea about people's behavior, it seems to be incompatible with the really full scale rational expectations.
