As of the last few days, the friends of Freakonomics are dominating the best seller list at Amazon.
The number one book is by Michael Roizen and Mehmet Oz. Michael Roizen used to own the house Levitt now lives in and was a doctor at the University of Chicago; Mehmet Oz is a longtime friend of Dubner.
The number three book is by Seth Roberts, the Berkeley professor/diet guru we wrote about last year and which Dubner blurbs on the front cover.
The number four book is Freakonomics.
And on Amazon U.K., last week there was a point at which two of the top five books were by economists. Tim Harford’s “The Undercover Economist” was #1 and Freakonomics was #5.
