Bill Gates has a web site, The Gates Notes, he just uploaded to the site books he read during a recent vacation. You can find the list here.
What's noteworthy about the list is that most of the books seem to come from a macro-aggregative view of the world. There are books about abundance, austerity, limits to growth and, of course, energy. Not one damn book that would seem to come into print if the authors and readers understood the basics of supply and demand, and marginal utility. There are no macro themes of abundance and limits to growth, if one understands that the economy adjusts to increases and decreases in supplies of goods and services.
It seems that Gates has his head very much in a Malthusian cloud.
Also noteworthy is his lack of books on business cycle and monetary theory. Given the financial crises in the world, one would think that this would spark some interest. Or has he concluded that cycles are just a part of nature and one should just plow on?
