In February 2004, when N. Gregory Mankiw, then chairman of the White House Council of Economic Advisers, caused a national uproar with a "textbook" statement about trade, economists rushed to his defense. Mr. Mankiw was commenting on the phenomenon that has been clumsily dubbed "offshoring" (or "offshore outsourcing") – the migration of jobs, but not the people who perform them, from rich countries to poor ones.
Offshoring, Mr. Mankiw said, is only "the latest manifestation of the gains from trade that economists have talked about at least since Adam Smith. ... More things are tradable than were tradable in the past, and that's a good thing." Although Democratic and Republican politicians alike excoriated Mr. Mankiw for his callous attitude toward American jobs, economists lined up to support his claim that offshoring is simply international business as usual.
