A 2015 study showed that Mexico`s prosperity increased by 1.31% as a result of NAFTA tariff reductions and by 118% for Mexico`s intra-Bloc trade.  Inequality and poverty have decreased in the regions of Mexico most affected by globalization.  Studies from 2013 and 2015 showed that Mexican small farmers benefited more from NAFTA than large farmers.   According to a 2012 study on tariff reductions on NAFTA, trade with the United States and Mexico increased by only 11% in Canada, compared to a 41% increase in the United States and 118% in Mexico. :3 In addition, the United States and Mexico benefited more from the rate reduction, with an increase in social benefits of 0.08% and 1.31%, with Canada recording a decrease of 0.06%. :4 In 2008, Canadian exports to the United States and Mexico totaled $381.3 billion, while imports totaled $245.1 billion.  According to a 2004 paper by University of Toronto economist Daniel Trefler, NAFTA provided Canada with a significant net benefit in 2003, with long-term productivity increasing by up to 15 per cent in the sectors that experienced the largest tariff reductions.  While the decline in low-productivity jobs has reduced employment (up to 12 per cent of existing jobs), these job losses have lasted less than a decade; Overall, unemployment has declined in Canada since the legislation was passed. Trefler commented on the compromise, saying that the crucial trade policy issue was „how free trade can be implemented in an industrialized economy so that the long-term benefits and short-term adjustment costs borne by workers and others are recognized.“  NAFTA was effectively negotiated by Bill Clinton`s predecessor, George H.W. Bush, who decided that he wanted to continue negotiations on opening trade with the United States. Bush initially tried to reach an agreement between the United States and Mexico, but President Carlos Salinas de Gortari insisted that a trilateral agreement be reached between the three countries.
After talks, Bush, Mulroney and Salinas signed the agreement in 1992, which came into effect two years later after Clinton was elected president. NAFTA has also used a new era of free trade agreements, which have multiplied as World Trade Organization (WTO) global trade negotiations, and has played a pioneering role in integrating labour and environmental provisions, which have become increasingly broad in subsequent free trade agreements [PDF]. The USMCA has put in place stricter enforcement mechanisms than the original agreement, which has led the AFL-CIO, the largest collection of U.S. unions, to support the pact – a rare endorsement from a group that has strongly criticized NAFTA. A 2014 study on the impact of NAFTA on U.S. trade employment and investment showed that the U.S. trade deficit with Mexico and Canada increased from $17.0 billion to $177.2 billion between 1993 and 2013 and supplanted 851,700 U.S. jobs.  The structure of NAFTA was to increase cross-border trade in North America and stimulate economic growth for the parties involved. Let`s start with a quick look at these two topics. On September 30, 2018, an agreement was reached when the NAFTA amendments were renegotiated. The next day, a renegotiated version of the agreement, called the U.S.-Mexico-Canada Agreement (USMCA), was published.
In November 2018, at the G20, the USMCA was signed by President Trump, Canadian Prime Minister Justin Trudeau and then-Mexican President Enrique Pea Nieto. Since NAFTA was adopted, U.S. trade interests have often expressed very satisfaction with the agreement. Trade has grown strongly between the three nations that are parties to NAFTA, but this increase in trade activity has led to growing trade deficits for both the United States with Canada and Mexico-;d the United States imports more from Mexico and Canada than it does.
