Seth wrote something here about Jane Jacobs and her relevance to experimental psychology. He mentions her book, Cities and the Wealth of Nations, which I too enjoyed reading.
I have one question, though, which perhaps the economists in the audience can anwer. I recall two messages from that book.:
(1) Certain cities produce great wealth and that it is the natural and unfortunate result of national tax and economic policies to bleed the cities dry until they can no longer be productive, leading to national decline.
(2) Import substitution is a good thing because it leads to dense networks of local factories and suppliers.
But I seem to recall reading somewhere that import substitution is very much out of favor among economists. Was Jacobs wrong on that one?
