Thanks for your replies.
Actually, my undergraduate major was Economics, but when I read Krugman I generally find his conclusions to not be supported. However, Krugman does have a Nobel Prize, he’s a professor at Princeton and my daughter who’s a sophomore in college is using his very expensive textbook for her International Trade class. So, I want to attribute some credibility to Krugman but I rarely find it in what he writes. Also, if what he writes were true, the solutions to current economic problems would be pretty simple.
