I’d never heard of the guy but the book was sitting there, it had good blurbs, and from a quick flip-through it looked interesting.

I am not an econometrician

I am a statistician, but I have worked in a department of predominantly econometricians for the past 17 years. It is a little like an Australian visiting the United States.
