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.
Kenneth ArrowThe 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.
Kenneth ArrowI think the idea that a society has to be responsible for all of its citizens, those who do well and those who do not, is really a precondition of a good society.
Kenneth ArrowKnowledge 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.
Kenneth ArrowFamily 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.
