Some of you may have in June read my post #98 in the Modern Monetary Theory thread wherein I briefly discussed and economic theory called "optimal tariffs" (OTT). It's long been clear to me that OTT is the notion that underpinned Trump's tariff on steel. Just as that's been clear to me, so too has it been clear that he's provided nothing that supports applying OTT in imposing a tariff on steel imported from the PRC, which is the key target country for that tariff. Let me explain why, and in doing so also point out a material omission from the prose in a just published Breitbart essay by John Carney, "What Trump Knows about Tariffs that Establishment Trade Economists Forgot."[SUP]1[/SUP]
From the essay:
Blue:
Kaldor's theory does not apply to the U.S. with regard to (raw) steel. It doesn't because the PRC produces over ten times the steel the U.S. does. Yes, overall the U.S. is economically large, but on an industry-by-industry basis, which is the basis that's relevant for Kaldor's theory, we're "productively large" in some and "productively small" in others.[SUP]3[/SUP] Insofar as we are not the top producers of steel, not even close, and cannot and won't be for a very long time, there is no way for Trump's tariffs to yield the returns proposed by OTT.
Brown:
Note:
From reviewing the above linked documents and research on OTT one finds that Carney omitted a key facet of OTT and that not one person in the Trump Admin has publicly attempted to air so much as even the most feeble reconciliation or exposition of the metrics of his tariffs vis-a-via OTT.
From the essay:
The idea, [introduced into modern economics in 1940 by British economist Nicholas Kaldor,][SUP]2[/SUP] is that for any large, wealthy country, a tariff can be used to increase national wealth rather than just protect domestic producers....Kaldor pointed out that the optimal tariff depended on three things. First, the tariff could not be too large—it probably has to be smaller than required to “protect” domestic monopolists. Second, the country has to be large enough to have something akin monopolistic power on global markets. Third, other countries would not retaliate.
Blue:
- Though the word "wealth" intervenes, the tariff imposing nation's wealth is irrelevant.
- Kaldor's theory does not say "any large country" can effectively avail itself of OTT. It says that an "economically large" country may be able to do so with regard to goods where on the supply side it can control the global prices of the product on which it'd impose the tariff.

Brown:
OTT depends heavily on the fact that other countries won't retaliate. That is a reasonable assumption when one applies an import tariff on a product whereof one has global monopolist power.4 When one the tariff applier hasn't monopoly power, however, others most certainly will retaliate by levying tariffs of their own. That they will is what's already come to fruition re: Trump's tariffs.
Note:
[*=1]Nevermind that "establishment" trade economists didn't at all "forget" about "optimal tariffs."
[*=1]For a brief overview of the history of OTT, click here.
[*=1]The same "large-small" concept applies on the demand side, but the demand side isn't germane to OTT; the point of OTT is to effect demand-side outcomes using one's supply-side dominance to (1) crate greater profits than would be realized absent the OT and (2) protect one's strength in a commoditized global industry/market. Notice that OTT is about exerting monopoly, no monopsony, power over the would be buyers of the products on which it places the tariffs.
[*=1]Think about it. If Eskimos put a tariff on imported ice, would you bother retaliating against their doing so?
