The switch to the market in Eastern Europe, of course, has not exactly been one of the greatest advertisements for the market. There's no question the socialist system - and I hate to use the word 'socialist,' but I suppose some description of a system in which the state is in control - was breaking down, really collapsing. In these countries, most markedly in Russia itself and in a number of the others, it obviously was based on a tyranny, which is unacceptable even if it were producing good economic results, which it was not.

The world is changing. We're not really proceeding on a stationary basis.

Economics in college was very poor; I was not very impressed with it. I actually wanted to study statistics. I discovered mathematical statistics as an undergraduate and was fascinated with it.

There are all sorts of institutions in the economic world which depart from the simple price/market model which I worked on in an earlier incarnation and which has been sort of the mainstream of economic theories since Adam Smith and David Ricardo. There are all sorts of contractual relations between firms and individuals which do not conform to the simple price theory - profit-sharing schemes and so forth - and the explanation for these suddenly became clear. We now understand why these emerged and that they are based on differences in information in the economy.

It seems to me that at least as far as the financial markets are concerned, there is increasing evidence against rational expectations, even at the macro level.

One thing I learned from meteorology is that being an actual science was no guarantee of exactness.

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.
