Economists generally agreed that the United States economy benefited overall from NAFTA as it increased trade. In a 2012 survey of the Initiative on Global Markets' Economic Experts Panel, 95% of the participants said that, on average, U.S. citizens benefited from NAFTA while none said that NAFTA hurt US citizens, on average. A 2001 "Journal of Economic Perspectives" review found that NAFTA was a net benefit to the United States. A 2015 study found that US welfare increased by 0.08% as a result of NAFTA tariff reductions, and that US intra-bloc trade increased by 41%.
