According to a World Bank study, NAFTA has brought economic and social benefits to the Mexican economy, but that it is not enough to reduce inequality in economic conditions between Mexico and the United States73.73 Mexico needs to invest more in education, innovation and infrastructure, as well as in the quality of national institutions. The study also finds that income convergence between a Latin American country and the United States is limited by large differences in the quality of national institutions, in the innovation dynamics of domestic firms and in the skills of the workforce. While NAFTA has had a positive impact on wages and employment in some Mexican countries, the domestic pay gap has widened as a result of trade liberalization.74 Another study finds that Mexico`s ability to improve economic conditions depends on its ability to improve its domestic institutions, adding that since NAFTA came into force. , Mexican institutions have not improved significantly compared to other Latin American countries.75 Which generates income, can hire more than other Latin American countries. Workers and maybe increase dividends to shareholders. This money is distributed several times by the economy, as a result of what economists call the multiplier effect of money, which says that for every dollar an individual receives as income, part is spent (i.e. consumption) and part is saved. If individuals save 10 per cent of their income, 90 cents will be spent on each $1 and 10 cent income. The 90 cents that are then spent are paid for another person, and another 90 per cent of them are spent on consumption. This will continue until there is nothing left of the original $1. The World Trade Organization (WTO) Trade Facilitation Agreement (TFA), if fully ratified, could also affect trade facilitation between NAFTA parties. Ninety-eight out of 109 countries have ratified the agreement.
The role of the Internet in international trade has expanded considerably since nafta began more than 20 years ago. While technological progress has profoundly changed the way businesses trade and operate across international borders, some companies say that new barriers have also been created that do not address existing trade rules. NAFTA parties may consider discussing issues related to the cross-border transmission of information electronically or the forced location of data centres. Such provisions could provide North American companies with greater flexibility in processing and storing data relevant to their operations. Some of these issues have been addressed in the TPP. The reason for these significant deviations from the original model is that the modern world of free trade is so different from the original historical framework of free trade models. Today, no one has clearly determined the best economic outcome on the basis of national natural advantages. Today`s global economy has not achieved the best result from international competition, where each country serves the best interests of the world by producing precisely the products it is naturally most efficient to produce.
On the contrary, there are many possible outcomes that depend on what countries actually do, what capabilities they actually develop, natural or human capacities.  The 115th Congress faces many NAFTA and international trade issues. On May 18, 2017, the Trump administration provided Congress with a 90-day communication on its intention to begin talks with Canada and Mexico to renegotiate NAFTA, as required by the 2015 Trade Promotion Authority (TPA). The government has also begun to discuss with members of Congress the extent of the negotiations.
