Economic Optimism? Yes, I’ll Take That Bet - Findings - NYTimes.com: "As an alternative to arguing, Julian offered to bet that the price of any natural resource chosen by a Malthusian wouldn’t rise in the future. Dr. Ehrlich accepted and formed a consortium with two colleagues at Berkeley, John P. Holdren and John Harte, who were supposed to be experts in natural resources. In 1980, they picked five metals and bet that the prices would rise during the next 10 years.
By 1990, the prices were lower, and the Malthusians paid up, although they didn’t seem to suffer any professional consequences. Dr. Ehrlich and Dr. Holdren both won MacArthur “genius awards” (Julian never did). Dr. Holdren went on to lead the American Association for the Advancement of Science, and today he serves as President Obama’s science adviser."
