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.

The health care provisions are presumably for individuals. And whoever pays for them, whether it's paid by the individual, state, whatever, the value is an individually based value. It has nothing to do with employment.

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.

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.

Evolutionary theory tends to explain quite well in retrospect how various species emerged. It's not very good on prediction. Nevertheless, one cannot say that there isn't a lot of knowledge that's been obtained in this field. In the same way, with these complex physical phenomena between solid state physics, you can say a lot of things without necessarily knowing the next step.

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

Education is still, in spite of private education, a state matter.
