Critics claim that the North American Free Trade Agreement (NAFTA) hurt American workers. But apparently NAFTA raised U.S. wages, according to a new study.

Wages, when adjusted for inflation, rose as a result of NAFTA in the countries that signed the free-trade agreement — the United States, Mexico, and Canada — according to a new paper by Yale economist Lorenzo Caliendo and Federal Reserve economist Fernando Parro. NAFTA, a free trade agreement between Mexico, Canada and the U.S. inked in 1993, boosted trade between the three countries, tearing trade down barriers such as tariffs.
