OK, apologies to Paul Krugman, now that I realize the Interstellar Trade paper was a joke and first drafted in 1978. I should have checked more before writing–but as noted, in the thick of writing the second edition of Debunking Economics, I latched on to a diversion.
However at some stage I’ll be publishing a critique of Paul’s paper on Minsky, which I wish was a joke… More anon once the book is finished.
