Kevin Hassett is right to be furious, but he is attacking the wrong target. When the former CEA Chairman called for the authors of a New York Fed study on tariffs to be disciplined, he wasn't just venting political frustration. He was pointing at a systemic rot in how we calculate the "cost" of trade policy. The study in question—the one claiming tariffs cost the average household $831 annually—isn't just a difference of opinion. It is a mathematical hallucination masquerading as peer-reviewed science.
If you are looking for a balanced take on trade deficits, go buy a textbook from 1994. If you want to understand why the "experts" keep getting the math wrong while your local manufacturing base erodes, you need to look at the static-modeling trap.
The New York Fed’s "worst paper" isn't a failure of effort; it is a failure of logic.
The Static Model Myth
Economists love "ceteris paribus"—all other things being equal. It is the ultimate intellectual crutch. They assume that if you apply a 25% tariff on steel, the only thing that changes is the price of the steel. They treat the economy like a frozen snapshot rather than a kinetic system.
This is where the $831 figure comes from. It assumes:
- Domestic producers will never increase supply.
- Importers will never find alternative sources.
- Currency values will remain perfectly rigid.
- Foreign exporters will not drop their prices to maintain market share.
In the real world, none of those things are true. When you tax an import, the exporting country’s currency often weakens. This offsets the price hike. More importantly, it forces a shift in the supply chain. I’ve seen procurement officers at Fortune 500 companies move entire production lines over a 5% margin shift. To suggest that a massive shift in trade policy results in zero behavioral change is not "neutral" science—it is malpractice.
The Deadweight Loss Obsession
Standard economic theory obsesses over "deadweight loss." This is the theoretical value lost when a tax or tariff prevents a transaction that would have otherwise occurred. The New York Fed researchers calculated this loss by treating a dollar of consumer savings as identical to a dollar of industrial investment.
They are not the same.
A consumer saving $2 on a cheap plastic toaster from overseas provides a one-time utility. A domestic factory producing that toaster provides 40 years of wages, tax revenue, and secondary service jobs. The "efficiency" of free trade is often just a transfer of wealth from the middle class to the capital class. The Fed's paper ignores the Multiplier Effect of domestic production.
Mathematically, if we use $M$ for the multiplier and $I$ for the investment in domestic production, the total economic impact is:
$$\Delta Y = \frac{1}{1-c(1-t)+m} \cdot \Delta I$$
Where $c$ is the marginal propensity to consume, $t$ is the tax rate, and $m$ is the marginal propensity to import. When you import everything, your $m$ is high, which shrinks your multiplier. The Fed study ignores this entire side of the ledger. They count the cost of the tariff but assign a value of zero to the preservation of the industrial base.
The Disciplined Mind vs. The Disciplined Academic
Hassett’s call for "discipline" sounds harsh to those who view academia as a sacred space for exploration. But the New York Fed is not a university. It is a policy-influencing arm of the central bank. When they publish a paper that uses flawed methodology to reach a politically convenient conclusion, they are engaging in advocacy, not analysis.
I have watched hedge funds lose billions because they trusted "static" models provided by PhDs who have never stepped foot on a factory floor. These models failed in 2008, they failed in 2016, and they are failing now.
The "worst paper" label fits because the authors willfully ignored the Dynamic Scoring reality. In a dynamic world, tariffs act as a catalyst for capital expenditure (CapEx). When you make it more expensive to outsource, you make it more profitable to build here.
The Missing Link: Currency Manipulation
You cannot talk about the cost of tariffs without talking about the exchange rate. The Fed paper operates as if the US Dollar is a fixed unit of measurement like a meter or a kilogram.
When a country like China faces a tariff, they don’t just eat the cost. They devalue the Yuan. This makes their exports cheaper in dollar terms, effectively absorbing the tariff. The US Treasury collects the revenue, the price at Walmart stays relatively stable, and the "cost to the household" evaporates.
Why was this not in the study? Because it ruins the narrative. It’s easier to run a spreadsheet with three variables than to account for the geopolitical reality of currency wars.
Why the "Expert" Consensus is Wrong
The "People Also Ask" section of any search engine will tell you that the consensus on tariffs is that they are "regressive taxes." This is a half-truth.
They are only regressive if you assume that the labor market is a fixed pool. If a tariff creates a job for a person who was previously underemployed, that person’s "cost" of $831 is offset by a $50,000 salary. For the academic earning six figures at the Fed, that $831 is the only number that matters. For the guy in the Rust Belt, the math looks very different.
The Hidden Advantage of Friction
Globalists argue that any "friction" in trade is an objective evil. They want a "seamless" world where goods flow to wherever labor is cheapest and environmental laws are weakest.
But friction is a tool of sovereignty.
A tariff is a price signal. It tells the market: "We value national stability over the cheapest possible price for a toaster." The New York Fed paper treats this preference as an error. It isn't an error; it’s a strategy.
The Data Trap
If you look at the raw data from 2018-2020, inflation remained remarkably low despite the "crippling" tariffs. If the New York Fed’s math were correct, we should have seen a massive spike in CPI specifically tied to tariffed goods. We didn't.
What we saw instead was a squeeze on foreign profit margins. The "experts" predicted a catastrophe that didn't happen because they refused to acknowledge that corporations have "fat" in their margins. When faced with a 10% tariff, a company often takes a 5% hit to profit and demands a 5% discount from their supplier. The consumer sees $0 of that change.
The Fed study is an insult to anyone who understands the ruthless reality of global supply chains. It is a fairy tale written for people who believe the world operates in a vacuum.
The Professional Price of Honesty
Admitting that tariffs can work is a career-killer in certain circles. If you want a job at a top-tier think tank or a seat at the Fed, you have to worship at the altar of David Ricardo’s Comparative Advantage.
But Ricardo lived in a world of gold-backed currencies and sailing ships. He didn't live in a world of digital currency manipulation, state-subsidized industries, and intellectual property theft.
The New York Fed authors shouldn't just be disciplined; they should be forced to work in a mid-sized manufacturing plant for six months. They need to see how "efficiency" actually works when you're the one being "offshored" for the sake of a 2-cent drop in the price of a consumer good.
Hassett’s anger isn't about partisan politics. It’s about the fact that we are making national security decisions based on the economic equivalent of a "Flat Earth" map. If the map says there’s a cliff where there is actually an ocean, you don't just "debate" the mapmaker. You stop using the map.
Stop asking if tariffs are "expensive." Start asking why the people calculating the price are so afraid of a domestic factory. If your model can't account for the value of a job, your model is broken. If your study ignores currency shifts, your study is propaganda.
Stop reading the Fed's white papers. Start watching where the capital is flowing. The market is smarter than the PhDs. It always has been.
Fire the modelers. Hire some engineers.
