1. All three countries saw real wages increase as a result of NAFTA. The effects in the United States and Canada, however, are fairly mild. Wages in Canada grew 0.96 percent, while U.S. wages grew 0.17 percent. That’s something, and given that U.S. wages have been stagnant or falling in recent decades, any gains are good news.

    But the real success story is Mexico, where wages grew 1.3 percent due to NAFTA. That’s to be expected, since trade with Canada and the U.S. is a more important part of its economy than, say, trade with Canada and Mexico is to the U.S. It also saw the biggest tariff reductions of the three, further amplifying the effects. 1.3 percent isn’t a ton, and the productivity gains the country has seen since have disappointed some former advocates. But it’s not nothing.

    This is the pattern generally with trade liberalization. All else being equal, all parties tend to benefit, but developing countries benefit most. That’s why global development advocates at institutions like the Center for Global Development have been pushing hard for the Obama administration to eliminate barriers that harm export industries in poor countries.
