I am opposed to a 20% tariff aimed at Mexican manufactured goods. I am more ambivalent about the 20% border adjustment tax (BAT) floated by the Trump administration. In fact, I may support it.
The basic idea is simple. U.S. companies would pay a 20% income tax. Companies could deduct domestically-sourced inputs from their income but not imported goods or services. Those imports would then, in effect, have to be at least 20% cheaper than equivalent domestic competitors.
The idea is to make the U.S. corporate income tax look like a value-added tax (VAT). If a corporation in Mexico buys an input from overseas, it pays the Mexican VAT on the purchase. If it sells something domestically, then it also pays the Mexican VAT. But if it sells something to a company in France, then it does not pay the Mexican VAT ... but the French buyer will pay the French VAT. Under the BAT, if a corporation in the U.S. buys an input from overseas, then it pays the U.S. BAT on the purchase. Ditto it pays the BAT on all earnings from domestic sales. But if it sells something to a French buyer, then it will not pay the U.S. BAT ... but the French buyer will pay the French VAT.
As it stands, the BAT will apply to oil imports. So an American refinery that buys foreign crude would have to pay the 20% BAT on those purchases! Right now, WTI trades around $54 per barrel. A refinery using American crude would pay $54; a refinery using imported crudes at a similar grade would pay $65. American oil prices would rise, world oil prices would fall.
And that is good for the world! Higher U.S. oil prices mean less U.S. oil consumption. Moreover, the burden will fall particularly on dirtier forms of oil. Most American crude oil imports (60% in 2015) are heavy grades. Almost half of that consists of heavy crudes from Canada, which release about significantly more carbon during the production process than other grades of oil. (So much so that the Section 526 of the Energy Security Act of 2007 theoretically banned U.S. federal agencies from purchasing it, although that has had no concrete effect.)
Lower world prices will, of course, stimulate more world consumption. But there are two wrinkles that will reduce that impact. First, transport links lock in most Canadian output to American markets. Last year, the Trudeau government approved an expansion of the Trans-Mountain pipeline from 300,000 to 890,000 bpd, which would allow Canada to divert as much as 28% of its current U.S.-bound exports to other markets. But that will take a long time and is a drop in the bucket of world production. Second, American refineries are optimized to use heavy crudes. They will switch away, but slowly, even if the cost of their primary input rises. Finally, inasmuch as world prices do fall, that will discourage foreign exploration and development, keeping some carbon in the ground for the long-run.
Winners:
- Our children;
- American heavy oil plays, of which there are not many outside Alaska;
- American light tight oil plays (hooray!);
- Andrés Manuel López Obrador (see below).
Losers:
- American oil consumers, who will likely see prices rise about 30₵ per gallon;
- Refiners who use imported crude oil—although not by very much;
- Canadian, Ecuadorean, Venezuelan and Mexican heavy oil producers, who are locked into the U.S. market;
- Mexican consumers, who rely on gasoline produced in the United States from Mexican heavy crude.
As far as energy is concerned, this does not strike me as a bad policy, even if it will impact Mexico quite seriously. At 2015 prices, a 20% BAT would have raised about $2.0 billion from Mexican crude oil imports, although most of that burden would fall on American consumers. The real hit for Mexico is that the increase in U.S. gasoline prices will be passed on to either Mexican consumers or the Mexican government. Inasmuch as the Peña administration hands Mexican voters a second gasolinazo, then it will be another fillip for AMLO’s chances in the 2018 elections.
So a good policy for energy: a net plus for domestic production and a net plus for decarbonization. Probably pretty good Harley-Davidson, as well.
But as far as other products markets are concerned, I’m still undecided as to whether the BAT is a good idea. Thoughts?
