First, a BIG caveat: there's a lot here, & it'll take time to draw definitive technical conclusions (esp given how the agreement is posted ustr.gov/trade-agreemen…). These are just initial opinions & subject to change as details emerge /1
1) as @JimPethokoukis rightly points out (aei.org/publication/tr…), this is generally a victory for pro-trade/globalization forces. NAFTA's basic free(r) trade principles (goods & services) remain, & uncertainty is reduced (tho not eliminated, yet). /2
1) Ex investment, the deal includes (and in some cases even expands) many of the "regulatory" FTA provisions often criticized by free marketers bc they are intrusive, costly or even protectionist: labor, environment, IPR, etc. Some like IP go beyond TPP /7
(Grumble: maybe if certain parties weren't so focused on making the deal more protectionist, arguing abt "national security" & tweeting insults, they could've fixed this stuff. Bah.) /10
1) Rules of Origin. The automotive ROO are managed trade on steroids, requiring originating (duty free) vehicles/parts to have high levels of not just total regional content, but also steel/aluminum purchases, & "high wage" labor. Many other onerous regs. /13
That may be the worst USMCA precedent of all /x
