I am no economist, but for an amateur I have a track record in predicting economic trends at least as good as Paul Krugman’s and I didn’t bother attending an Ivy League school to be able to do that. In predicting economic bubbles there are two things to remember. One is that most bubbles deal with intangibles, such as Michael Milliken’s junk bonds and the dot com bubble that saw insane valuations for non-performing stocks simply because they had an “E” in front of their name.
