Family is a difficult matter. I must admit I do not know that the state can intervene successfully in a family. It's a fact that everything is connected with the individualist temperament, the kind of economic environment which stresses the individual, but this is not directly the result of a state policy, nor do I see any good way by which the state could intervene except in some marginal ways.

Now virtue may not always be its own reward, but in any case it is not usually bought and paid for at market rates.

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.

From the time I first understood economic principles, I was always concerned also that any system be operated on an efficient basis, which meant decentralization because knowledge is not concentrated anywhere. It's based on motivation, and so these are the advantages of, say, the cautious case for capitalism, that the market system is efficient.

The MD is well aware that the forecasts are no good but he needs them for planning purposes.

Knowledge is a free good. The biggest cost in its transmission is not in the production or distribution of knowledge, but in its assimilation. This is something that all teachers know.

I think the development of the venture capital system has been an example of something which is a successful improvement in risk-bearing. It doesn't exactly remove the risks at the beginning, but at least creates greater rewards at a slightly later stage and therefore encourages, say, small companies to engage in technologically risky enterprises.
