I’m going to be scathing in my critique because these people are both dishonest and incompetent and deserve to be called out on it.
Here’s their formula:

It’s a ridiculously simplistic formula.
First, a stylistic quibble. What is up with those asterisks in the denominator? I’ll give the authors the benefit of the doubt and assume that they wanted the formula to be understandable by people who aren’t familiar with standard math notation, in which the juxtaposition of variables indicates multiplication. But to see it written that way in an official document is just… weird.
The i subscripts in the formula just indicate that the formula is to be applied to one country at a time — country i. I’ll therefore omit the ‘i’s from the rest of the discussion.
∆𝜏 is the amount by which the tariff currently being placed on that particular country should change (according to the Trump administration bozos) in order to drive the bilateral trade deficit to zero. In other words, 𝜏 (the existing rate) + ∆𝜏 (the change in rate) would be the correct final rate (according to the formula) to achieve the dubious goal of a trade balance.
The inanity of insisting on bilateral trade balances
We’re off to a bad start already, because the notion that every bilateral trade deficit should be zero is ridiculous on its face. Let’s look at a simplified example. Suppose Malawi sells us only mangoes, and the US (henceforth ‘we’, since I’m American) sells them only air conditioners. In order for the trade deficit to be zero, we need to buy the same dollar amount in mangoes that they buy in air conditioners, and we should adjust the tariffs we impose on Malawi until that happens. Why is this desirable? Why should the amount of mangoes be linked to the amount of air conditioners? Who the hell knows? It’s just Trump’s idiotic obsession, and it makes no sense.
To make the stupidity even more obvious, think of an analogous situation. Ernesto sells tacos from a taco truck, and George runs a landscaping business. George occasionally buys tacos from Ernesto, and Ernesto hires George to mow his lawn. Suppose Ernesto pays more to George each month than George spends buying tacos from Ernesto. Is Ernesto being cheated? Is he subsidizing George? No and no. George gets every taco he pays for, and Ernesto gets his lawn mown on schedule. It would be ridiculous to say that either of them is being cheated, and ridiculous to say that the goal should be to make the amounts even.
Why is Trump obsessed with trade deficits? It’s because he is confused enough to believe that the existence of a bilateral trade deficit — a trading deficit with a particular country, Malawi in my example — means that they are cheating us and that we’re subsidizing them. He actually believes that we are just handing over the money, getting nothing in return. In reality, we get every frikkin’ mango we pay for, and they get every air conditioner they pay for. No one is being cheated, and to demand that the dollar amounts should match is idiotic and pointless.
Trump actually declares in his executive order that trade deficits are a “national emergency”. He does this because he doesn’t have the authority to impose tariffs unless it’s a national emergency. Otherwise, the job falls to Congress, where it belongs. Trump is lying about the supposed national emergency.
The formula
According to the USTR statement, the x in the formula is the dollar value of what we export to a particular country, while m is the dollar value of what we import from them. The numerator, x – m, is therefore equal to the trade imbalance. If x is bigger than m, then the difference is positive, and we are running a trade surplus. If x is less than m, then x – m is negative, and we have a trade deficit. But note that they have it backwards in the formula: it should be m – x, not x – m. Why? Because the denominator is positive. If both the numerator and denominator are positive, as they would be in the case of a trade surplus, the formula would deliver a ∆𝜏 that is positive. In other words, the formula as written would actually increase the tariffs for the countries with whom we have a trade surplus, and it would decrease the tariffs for countries with whom we have a trade deficit. The formula therefore punishes the (supposedly) good guys and rewards the (supposedly) bad ones, which is opposite to the administration’s intentions. One more indication of their clown car incompetence.
They could easily have corrected the formula if they were aware of the error. Just put a negative sign in front of the formula, or swap x and m, or redefine x and m as the amounts exported and imported by the other country, instead of the amounts exported and imported by the US. Any one of those three would fix the problem, but no.
Let’s assume that we have corrected that mistake for them and that the numerator now equals the amount of the trade deficit, not the surplus. What about the denominator? Well, it just so happens that the values they chose for 𝜀 and 𝜓 are 4 and 0.25, respectively. Those multiply to 1, thus canceling each other. How convenient. These charlatans actually and blatantly chose the values so that they would cancel out, instead of using the most accurate numbers they could find in the literature. They cheated.
After that suspiciously convenient choice of parameters, the formula is now just ∆𝜏 = trade deficit divided by total imports:

Do they actually apply this formula? No. They massage its output even more. They divide ∆𝜏 by two, for no good reason. That means that for the formula to match the actual tariffs, they should multiply the denominator by 2. They fail to do that, as you’d expect. Why 2? My hypothesis is that even those dunces realized that the numbers they were getting from the formula were ridiculously large, and dividing by 2 was a way to get them down to a range that they considered reasonable. More number fudging with no theoretical justification.
Next problem: according to the corrected formula, ∆𝜏 should be negative in the case of trade surpluses. That is, we should decrease the tariffs on imports from those countries. If the existing tariff rate is small enough, it should even go negative, according to the formula, in order to balance our trade with that country. Trump doesn’t like that, so he has arbitrarily declared that everyone will pay a minimum of 10%, whether there’s a trade deficit or a trade surplus. In other words, the policy, which is already misguided, is also unfair — it says that it’s OK for the US to screw other countries by imposing high tariffs, even if they’re doing the “right” thing and allowing us to run a trade surplus with them.
The actual rates
Here are the charts spelling out the actual tariff rates.

The chart labels them “Reciprocal Tariffs”, but that is a lie, since the formula doesn’t take into account the tariff rate charged by the other countries on our exports to them. It’s completely missing from the formula. They aren’t reciprocal tariffs, they’re misguided tariffs in response to trade deficits, and they punish US importers instead of the countries selling us those goods and services.
The label on the middle column is wrong for the same reason, and it’s even further wrong because it depicts a bilateral trade deficit as a quantifier of “currency manipulation and trade barriers”, which it isn’t. We can run a bilateral trade deficit for no other reason than that Americans want more of what the other country is selling us than they want from us. That’s not “currency manipulation and trade barriers”, and the Trump administration is dishonest for trying to sell it that way.
The numbers in the middle column are apparently those that come straight out of the formula. You can tell, because the tariffs that are actually being imposed by the US are just the middle column divided by 2. That’s the arbitrary factor of 2 I mentioned above. The only exceptions are in those cases where dividing by 2 would leave a less than 10% tariff, in which case the tariff is set to 10%. Gotta make sure that everyone gets screwed at least that much.
The US Trade Representative’s explanation
Now some excerpts from the USTR statement. The very first paragraph:
Reciprocal tariffs are calculated as the tariff rate necessary to balance bilateral trade deficits between the U.S. and each of our trading partners. This calculation assumes that persistent trade deficits are due to a combination of tariff and non-tariff factors that prevent trade from balancing. Tariffs work through direct reductions of imports.
Well, duh. The phrase “tariff and non-tariff factors” covers literally every possible factor in the entire world. Yes, there are actual reasons that we buy more in mangoes from Malawi than they buy from us in air conditioners. Therefore we should conclude that we’re getting ripped off?
While individually computing the trade deficit effects of tens of thousands of tariff, regulatory, tax and other policies in each country is complex, if not impossible, their combined effects can be proxied by computing the tariff level consistent with driving bilateral trade deficits to zero.
Not by any reasonable person. You need to do the homework before making policy decisions that will affect the entire world economy. If they want less of what we’re selling than we want of what they’re selling, that can lead to a trade deficit, independent of all the factors they list above.
This doesn’t mean that trade practices can’t be unfair, but it does mean that to assume something nefarious is going on merely because we’re running a bilateral trade deficit is stupid.
If trade deficits are persistent because of tariff and non-tariff policies and fundamentals, then the tariff rate consistent with offsetting these policies and fundamentals is reciprocal and fair.
No. If we like Malawian mangoes more than the Malawians like our air conditioners, nothing is broken. Nothing is unfair. No reason to blindly punish the Malawians. It just means that American demand for Malawian mangoes is greater than Malawian demand for American air conditioners. No big deal.
A case could be made for nudging the US’s global trade deficit — which is the aggregate trade deficit we’re running with all of our trading partners put together — toward zero, but trying to eliminate every bilateral trade deficit is bonkers. These people are clueless.
Consider an environment in which the U.S. levies a tariff of rate τ_i on country i and ∆τ_i reflects the change in the tariff rate. Let ε<0 represent the elasticity of imports with respect to import prices…
Right there they say that ε < 0, but a few sentences later they assign it a value of 4. The last time I checked, 4 was greater than 0, not less. Their sloppiness is consistent, at least. What is wrong with these folks?
let φ>0 represent the passthrough from tariffs to import prices, let m_i>0 represent total imports from country i, and let x_i>0 represent total exports. Then the decrease in imports due to a change in tariffs equals ∆τ_i*ε*φ*m_i<0. Assuming that offsetting exchange rate and general equilibrium effects are small enough to be ignored, the reciprocal tariff that results in a bilateral trade balance of zero satisfies:

As noted earlier, they have the numerator backwards. It should be positive for a trade deficit, not negative, in order for ∆𝜏 to be positive, which represents an increase in tariff rates.
To calculate reciprocal tariffs, import and export data from the U.S. Census Bureau for 2024. Parameter values for ε and φ were selected. The price elasticity of import demand, ε, was set at 4.
Which inside the Trump administration is less than 0, lol. And how convenient that εφ multiplies to 1, as noted above.
Recent evidence suggests the elasticity is near 2 in the long run (Boehm et al., 2023), but estimates of the elasticity vary. To be conservative, studies that find higher elasticities near 3-4 (e.g., Broda and Weinstein 2006; Simonovska and Waugh 2014; Soderbery 2018) were drawn on. The elasticity of import prices with respect to tariffs, φ, is 0.25.
It wasn’t to be conservative. It was to fudge the numbers so that the product εφ came out to be 1. And picking a value of 4 for elasticity isn’t “being conservative” in the sense of “this value is more likely to be correct”. It’s conservative in the sense of “we’d better make this number big because otherwise the tariffs will be so outrageously huge that everyone will see that we’re idiots.”
Think about it. They want φ to be small (whether or not the evidence supports it), because they want to maintain the fiction that other countries will mostly absorb the tariffs and that importers and retail customers will shoulder less of the burden and therefore experience less inflation. On the other hand, a small φ balloons the value of ∆𝜏 to ridiculous levels. So they set 𝜀 to 4 to bring ∆𝜏 down, even while acknowledging that the true value of 𝜀 is closer to 2.
The recent experience with U.S. tariffs on China has demonstrated that tariff passthrough to retail prices was low (Cavallo et al, 2021).
I haven’t verified that, but either way I would sure like to see the actual number. Why didn’t they include it? Is it really 0.25? In any case, the question of pass-through to retail prices is irrelevant when you’re trying to determine which country is absorbing the cost of the tariffs. It’s the pass-through factor to importers that is relevant, and that is close to 1, even if the pass-though to retail customers is less. That means that US importers are bearing the cost of the tariffs and passing some of that cost on to consumers. It’s inflationary, and it’s a tax by the US government on US importers, not a tax on foreign countries. Which contradicts Trump’s whole rationale.
The reciprocal tariffs were left-censored at zero.
No, they were “left-censored” at 10, as you can see by looking at the charts. 10 is the minimum tariff you’ll see in the third column of the charts.
Higher minimum rates might be necessary to limit heterogeneity in rates and reduce transshipment.</p
No explanation of why “heterogeneity in rates” is to be avoided, and no comment on the fact that it isn’t avoided, given the large range of new tariff rates in the third column of the charts. That means there’s still plenty of incentive for transshipment. Take Vietnam, for instance, with a new rate of 46%. There’s a *lot* of incentive for them to transship through one of the countries with a 10% rate.
Tariff rates range from 0 to 99 percent.
There is no inherent limit. Tariffs could be 100%, 180%, or 2100%. 99% is an arbitrary limit. Tariffs could even be negative in a perverse world, in which case the government would be giving importers a bonus for importing more and nudging us toward a trade deficit. Obviously that wouldn’t happen in practice, but my point is that the 99% is arbitrary, and anyone who thinks tariffs are limited to being less than 100% doesn’t understand tariffs.
The unweighted average across deficit countries is 50 percent, and the unweighted average across the entire globe is 20 percent.
It’s pointless to state the unweighted average. An unweighted average is really just a weighted average with all of the weights set to 1. That gives Liechtenstein equal weight with China, which is stupid. Our trade volume with China is some 1,770 times as great as our trade volume with Liechtenstein, but these geniuses are weighting them evenly and presenting the average as if it had some kind of significance. Morons.
Weighted by imports, the average across deficit countries is 45 percent, and the average across the entire globe is 41 percent. Standard deviations range from 20.5 to 31.8 percentage points.
Here, they tell us that the import-weighted average of tariffs is 41 percent. Combine that with their assumed pass-through rate of 0.25. meaning that exporters in other countries will shoulder 75% of the tariff burden. That’s unrealistic and it clashes with the actual data, but even if you take the Trumpers at their word and assume that only 25% of the additional cost due to tariffs is passed to importers, that’s still over 10%, because 0.25 * 41% is greater than 10%. 10% import inflation! So much for Trump’s campaign promise: “I’ll reduce prices on day one.” Idiot.
Good job, Trump supporters. By voting for him, you put power in the hands of these dishonest and incompetent economic doofuses.
colewd:
Of course he did! He requested federal help from Biden before the inauguration and from Trump after the inauguration. He acted on behalf of the people of California. That’s what he’s supposed to do. He’s the governor. It’s his job.
Did you even read the quote I gave you from the LA police chief?
The police chief did not want federal involvement. He did not request federal involvement. Trump forced it on him, knowingly breaking the law in the process.
The police chief isn’t an idiot. He had other options, and he knew — as is obvious to anyone with a lick of sense — that sending in troops would inflame the situation.
Oh, wait — who am I to question the Dear Leader’s decision? The police chief is merely the guy on the ground, in LA, coordinating the response. He knows nothing about the situation. Newsom is the governor of the state. He knows nothing about California. The Dear Leader, who knows more about everything than anybody, is the one who should be making the decisions. He understands what’s going on in LA far better than the police chief or the governor. Sure, he’s 3,000 miles away, but despite the distance, he grasps it in a way that the police chief and governor could never match. That’s how impressive he is! We can trust him; he is far wiser than us, and he always, always, acts in the best interests of the people. When he breaks the law or violates the Constitution, it’s because he loves us and knows what’s best for us. He’s not going to let the law, or the Constitution, or a bunch of corrupt judges stand in his way. That’s how much he loves and cares for us. I was way out of line for questioning him.
keiths,
Your list are bald assertions that you are spinning to support a narrative.
How much jail time have they spent? Was this less than a typical assailant if we compare like crimes? These are important details and again you speak in generalisations and not real facts. This is characteristic of living in the echo chamber.
It is possible that these pardons were inappropriate however you have not come close to making this case.
colewd:
You haven’t refuted a single one of them, despite being asked repeatedly to do so. Yet you’ve claimed that I have “Trump Derangement Syndrome”, am “unable to filter bias”, and that I am relying on “anecdote” and “suspect sources”. You’ve characterized my list as “a conglomeration of antidote [sic] and spin that is propaganda” and “bald assertions that you are spinning to support a narrative”.
If that’s all true, then it should be easy for you to show that I’m wrong. Here’s my list again, since we are on a new comment page:
Have at it. Stop stalling. Tell me what I got wrong. Expose me for the TDS-deranged propagandist that I am.
To date, you haven’t disputed a single thing I’ve said, including the fact that Trump pardoned people who were convicted of assaulting police officers on January 6. The only thing you’ve done is to try to justify Trump’s pardon, first by complaining about how other January 6 defendants were treated (which made no sense), and since that didn’t work, you are now suggesting that the assailants’ sentences were unfair compared to others who committed “like crimes” and that Trump was just trying to rectify this injustice. That’s bullshit. Trump didn’t examine these on a case-by-case basis. He issued a blanket pardon for over 1,500 people. A blanket pardon for anyone convicted of a January 6-related crime.* Commit a violent crime for Donald Trump, and he pardons you. But if someone spits at a soldier in LA,Trump says “they will be hit harder than they have ever been hit before”.
Trump doesn’t give a shit about justice. You should be ashamed of yourself for supporting him, Bill.
* Except for 14 people who were members of the Oath Keepers and Proud Boys. They received commutations, not pardons, but they walked out of jail just the same.
keiths,
I understand one pardon extended to child pornography, because it was discovered under a J6 warrant.
colewd,
Yes, federal help was necessary, and requested. But Trump’s opening the sluices was performative nonsense, and his criticisms of Newsom petty and irrelevant.
Do you agree that gutting Park and Forest services risks worse fires? Are you OK with opening them up for development and exploitation?
That’s ironic, given Trump’s greed – pushing family bitcoin, accepting gifts for personal use.
keiths,
This is essentially your argument. Bald assertions with no substance. We don’t mutually learn anything with this type discussion.
On the question of pardons I did some research and agree there were a couple of pardons that were questionable.
Allan Miller,
I have not opinion or expertise here. Can you expand on this?
