"The bottom line is that even free-trade zealots do not support dumping because it is an uncompetitive practice and not a true reflection of market forces."
Hmm, I'm not so sure about that one. I don't think economist Greg Mankiw would mind being called a "free trade zealot," so I'm going to quote a blog post of his in which he was criticizing something Larry Summers said on trade:
Larry is famous for being forthright about his views. He knows enough about our trade laws to know that they make little sense. So instead of feigning ignorance, why doesn't he call for repeal of the antidumping laws?
