Trade and labor markets : lessons from China's rise : the China Shock has challenged economists' benign view of how trade integration affects labor markets in developed countries

Economists have long recognized that free trade has the potential to raise countries’ living standards. But what applies to a country as a whole need not apply to all its citizens. Workers displaced by trade cannot change jobs costlessly, and by reshaping skill demands, trade integration is likely to be permanently harmful to some workers and permanently beneficial to others.
