Ep. 384 Explaining Optimal Tariff Theory and Its Relation to Standard Free Trade Arguments
Bob first explains the neoclassical theory of “optimal tariffs,” by which a large country can use a modest tariff to improve its terms of trade. He then shows how this theoretical possibility is consistent with standard arguments making the case for free trade.

Assuming I am stupid and there’s not-stupids here: Why didn’t Bob or Josh come up with the very first austrian objection to the ‘Optimal Tariffs’ approach. What is unseen in that claim of improved status due to lower import prices?
Well the China-tariff-lowered world-price is the price available to your other competitors (notChina), for purchasing input factors of production. Tariffs on any import factors puts you at the comparative disadvantage to nonChina in sourcing the input factors from China.
It doesn’t matter that the world price got lowered, cause your importers get the taxed price, competitors get the untaxed price, and can do far more things with those factors due to lower marginal costs versus alternatives.
Additionally Optimal Tariff theory fails to account that every cent in government hands is a net harm to society. A-priori. It’s not subject to price-test and therefore is, in agreggate, on the mean, unprofitable, capital-destructive, human-life-destructive.
What am I missing here guys?
Is the entire Trump-Tariff discussion supposed to be magically constrained to consumer end-products and not any input factors of production? Oh?, And what are those exactly, i wonder, that cannot ever be used as an input factor in some kind of production?
Thanks for bringing the topic to our attention, but to my mind the most GLARINGLY OBVIOUS objection to the price-lowering argument is that your producers and consumers nonetheless suffer higher prices than everyone else in the world.
Celebrating that is satanic.
Yes i was ignoring changes in Dollar Value here. But their claim doesn’t rely on it.
I’m still at a loss as to how we are all supposedly better off by paying more for stuff.
If tariffs make us better off, why do we tolerate no tariffs between states? Or cities? Or individual households? Seems silly to purposely cripple ourselves like this.
The tariffs hurt the outside party. So if two US states imposed tariffs on each other, they would both be poorer than if they didn’t. At the end of the episode, I explained why–even if we stipulated the “optimal tariff” literature–it would still make sense for economists to champion international free trade agreements.
It’s just bizarre to talk about this as an economic theory.
But we know Economists love getting into the intervention-modification debates.

It’s at least got a foundational understanding of the price distortions we incurred by reserve currency status.
But then there’s stuff like “America runs large current account deficits not because it imports too much, but it imports too much because it must export USTs to provide reserve assets and facilitate global growth. ” That ‘must’ is someone’s order, “obey or else”, and not economic law.
He continues: “Tere are no meaningful alternatives to the dollar or the UST. A reserve currency must be convertible into other currencies, and a reserve asset must be a stable store of value governed by reliable rule of law. ” Again the context here is an unacceptable evil, but ok I’m not his audence.
I think we really are watching the resistance to the CBDC thing. A inter-elite confrontation over a very global commification.
Really good analogies and comments reviewed at the end. Re-listen to this one folks! Pay attention this time!
But look at P25 of the document, it’s handwaving:
“Classically, modest tariffs can improve welfare because reduced demand from the tariff-
imposing country depresses prices of the imported goods.14”
“Improve welfare” “Decrease prices?” Look the price after tax goes UP. For the consumer the price goes UP. The GLOBAL PRICE DECREASES, BUT WE DON’T GET THE BENEFIT OF THAT.
“While the tariff produces distortionary welfare losses due to reduced imports and more expensive home production, up to a point, those losses are dominated by the
gains that result from the lower prices of imports.”
ASSERTION: NO CAUSAL LOGIC.
