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.

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.

One doesn't like instabilities in markets; they may be damaging, but probably not fatal, as the October '87 crash showed. It turned out to be essentially inconsequential. So if that's true, I'm not very worried about the welfare of those who are investing any more than I am about the welfare of those who go into casinos.

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.

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.

There is a bit of a problem with the match between derivative securities markets and the primary markets. We have long ago instituted principles, essentially high margin requirements, to prevent certain instabilities in the stock market, and I think they're basically correct. The trouble is that there's a linkage, let's say, between something like the stock market and the index futures markets, and the fact that the margin requirements are very different, for example, played some role in the October '87 crash.

I don't believe that unemployment is all voluntary, by anticipation of future wage movements or this sort of thing. I know you can modify the models by taking into account the indivisibilities, but I don't really think that people are voluntarily unemployed.
