The USMCA is expected to have a very small impact on the economy.  An International Monetary Fund (IMF) discussion paper published at the end of March 2019 stated that the agreement would have a “negligible” impact on the general economy.   The IMF study predicted that the USMCA “would have a negative impact on trade in the automotive, textile and clothing sectors, while achieving modest welfare gains, mainly due to improved access to the goods market, with a negligible impact on real GDP.”  The IMF study found that the economic benefits of the USMCA would be greatly enhanced if Trump`s trade war ended (i.e., when the United States lowered tariffs on steel and aluminum imports from Canada and Mexico and that Canada and Mexico will lower retaliatory duties on imports from the United States)  From June to the end of August 2018 , Canada has been sidelined due to bilateral discussions between the United States and Mexico.  On August 27, 2018, Mexico and the United States announced that they had reached a bilateral agreement on a revised NAFTA trade agreement, which includes provisions that would boost U.S. auto production a 10-year data protection period against generic drug production on an expanded list of products enjoyed by pharmaceutical companies. , particularly U.S. manufacturers of high-quality bionological drugs. , a sunset clause – a 16-year expiry date with periodic audits over 6 years to eventually extend the contract for an additional 16 years, and a high de minimis threshold, where Mexico increased the de minimis value of US$50 in terms of duty-free and tax-free online purchases to $100.   According to an August 30 article in The Economist, Mexico has agreed to increase the rules of origin, which would mean that 75% of a vehicle`s components must be manufactured in North America, as opposed to the previous 62.5%, in order to avoid tariffs.  Given that automakers are currently importing cheaper components from Asia, consumers would pay more for vehicles under the revised agreement.  In addition, approximately 40 to 45 per cent of vehicle components must be produced by workers earning at least $16 an hour, as opposed to the current $2.30 per hour that a worker earns on average at a Mexican auto plant.   The Economist described this as a “Mexican car construction in a straitjacket”.
 No new trade agreement can be concluded until the transition is complete. The overall effect of the agricultural agreement between Mexico and the United States is controversial. Mexico has not invested in the infrastructure needed for competition, such as efficient railways and highways. This has led to more difficult living conditions for the country`s poor. Mexico`s agricultural exports increased by 9.4% per year between 1994 and 2001, while imports increased by only 6.9% per year over the same period.  A Chapter 19 panel should consider whether the Agency`s decision was supported by “substantial evidence.” This standard was a considerable tribute to the national agency. Some of the most contentious trade disputes in recent years, such as the U.S.-Canada dispute over conifers, were negotiated ahead of chapter 19 panels. The UK government is also conducting trade negotiations with countries that do not currently have trade agreements with the EU, such as the United States, Australia and New Zealand.
The EU insists that the UK must respect these rules precisely enough – so that British businesses have no advantage – but the UK government says it wants the freedom to move away.
