The general uncertainty about the prospects of medical treatment is socially handled by rigid entry requirements. These are designed to reduce the uncertainty in the mind of the consumer as to the quality insofar as this is possible. I think this explanation, which is perhaps the naive one, is much more tenable than any idea of a monopoly seeking to increase incomes.

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.

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

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.

Usefulness depends on tractability.

Some people say Russia is running at 50 percent of its gross domestic product under that during the Communist period. In fact, none of the countries seems to have recovered the level that they had under communism, although the other countries in Eastern Europe are doing better than Russia and particularly the Czech Republic seems to be doing modestly well. East Germany I can't count because they have a rich uncle. You have economic benefits which have nothing to do with the workings of the system.

Markets are not, in my opinion, a full solution to any problem. The obvious problem they don't meet is the concerns of the welfare of individuals who may get lost in the operation of the system - the distributional question. We've seen this growing as we go further and further toward a market ideology in the United States and the United Kingdom. We've seen a decline in the welfare of the working poor, leaving aside any other pathologies, just the working poor, a very distinct increase at the very top levels.
