Our sister publication “Law & Liberty” published a piece recently by Oren Cass in which he criticizes economists for their beliefs in free trade and trade based on comparative advantage. It’s “Free Trade’s Origin Myth,” Law & Liberty, January 2, 2024.
Co-blogger Pierre Lemieux has criticized the collectivist premise that Cass uses in his discussion. There’s also much economic content to criticize in his article. I want to focus on one important misunderstanding. Cass writes:
Since 1992, the United States has accumulated $15 trillion in trade debt—goods and services consumed by Americans for which nothing was produced in return.
He gets to that figure, presumably, by adding up the yearly current account deficits between 1992 and now. But he never tells the reader why he thinks that trade deficits translate, dollar for dollar, into debt.
They don’t.
When there’s a current account deficit, there’s necessarily an offsetting capital account surplus. When foreigners sell us goods and services, they have basically five things to do with the money that they don’t spend on our goods and services: (1) buy U.S. dollar-denominated debt, typically U.S. government Treasury bills and bonds; (2) buy stock in U.S. companies; (3) buy land in the United States; (4) directly invest in the United States; and (5) hold on to the actual currency because it’s still the world’s leading currency. In only one of those cases, case (1), does the current account deficit translate into debt.
It’s understandable that Cass makes that mistake because many bona fide economists do. They often talk about the capital account surplus as if it’s all debt, even though they know (or should know) better.
I wrote about some of this in 1988, when many observers, not including me, were worried that Japanese people would take an outsize share of U.S. capital assets. It’s titled “America for Sale?” Reason, July 1988.
By the way, to the extent (5) applies, the U.S. Federal Reserve makes out well. It costs the U.S. government under 30 cents to print a $100 bill. And in return for that $100, we get actual goods. As Jay Leno said, in a 1989 ad for Doritos, “Crunch all you want; we’ll make more.”

Then again, mean wealth of the bottom 40% was $7,000 in 1983 but -$7,200 in 2019. There’s a good example of the problem with statistics.

Agreed. I disagree with Don about a number of things but his writings totally changed my mind about this issue. I do think it’s something you need to read about multiple times and let it percolate for a while since popular writing on this portrays it as so pervasively bad and politicians misrepresent it so often that its hard to shed what you have heard for so long.

Is just everybody’s dream to be able to transform non-collateralized promises of future payments into actual goods and services you can eat, drink, drive … in one word, enjoy.
Cass is, very likely, protestant. That would explain why he looks at “enjoying” with distrust. Maybe what is needed is converting the US to Southern European Catholicism, where “enjoying” have a well-deserved good name.
Pierre Lemieux

José: When the foreigners transform all these dollars into goods and services (by importing them from American producers), protectionists will jump with joy, or should already do so in anticipation. I suspect that Cass, despite your hypothesis, will jump too, because these will be exports from America.

It is also worth pointing out that despite our net indebtedness, U.S. income from U.S.-owned foreign assets (primary income receipts) noticeably and persistently exceeds payments to foreigners for U.S. assets (primary income payments). This is overwhelmingly due to investment income flow differentials. In other words a key U.S. export is safe paper. If I’ve done the chart correctly, it’s often even exceeded the trade in goods and services deficits!

Like the USG debt, many people taka an alarmist view of trade deficits. The pushback in this post is well taken.
Nevertheless, one can ask if the levels of USG defects and trade deficits are optimal. While I know of no criteria to judge whether are trade deficit is good or bad, there is for the USG deficit. There I’d say if the deficit arises from expenditures with NPV =< 0, deficit is too large by that amount. Of course if there are expenditures with NPV > 0 that are not made, then the deficit is too small. On the taxation side, the rule would be that the marginal expenditure that the tax prevents also be NPV =< 0. [It is understood that NPV are calculated at MC and MR which could differ from market prices of inputs and outputs and that that MR amd MC include positive or negative externalities.]
Jon Murphy
Jan 6 2024 at 11:59am
For simple price theory reasons (actors do not bare the full cost of their actions), I do not think government debt is likely optimal. Like any market suffering from an negative externality, quantity demanded is likely to be too high.
Further, for reasons I argue here (and elsewhere), I think NPV is a necessary but insufficient approach to ensure the optimality of public spending.
Thomas L Hutcheson
Jan 7 2024 at 6:19am
Plausible. Since there many things that are hard to “calculate,” NPV is a kind of shorthand for “rational decision making.” Send a link to your more expansive “criterion.”
Jon Murphy
Jan 7 2024 at 11:13am
No, it’s not. That’s the point here. NPV can help, but it is not “rational decision making.”
I don’t have a “more expansive criterion.” By flattening the decision-making process down to a criterion, it removes the very problem economists are trying to study: decision-making under scarcity.
Further, with non-market decision making, CBA has significant shortcomings because it cannot be done at the collective level the same way as at the individual level. “Cost” and “Benefit” do not mean the same thing, so the interpretation does not hold. See, for example, Buchanan’s Introduction to his edited collection “LSE Essays on Cost”

Even if Cass were right, that trade deficits = debt 100% of the time, his argument that it is a bad thing does not necessary hold. Debt can be good or bad. Debt that is good, debt that is used for productive purposes, is a good thing. Debt allows Americans to buy homes, buy cars, grow businesses, build infrastructure, etc. All the things that help boost economic wellbeing. And, because we can tap into the savings of foreigners, we can grow at a lower interest rate: fore investment funds are avalible and at a lower cost.
Of course, debt can be bad as well. But Cass does not provide any evidence anywhere that $15 trillion in debt (his calculation) is bad. He just asserts it and assumes his readers are irrationally debt adverse.

The main problem with the trade deficit is that it’s an export of demand & an import of unemployment. This depresses wages, our industrial base has been hollowed out as a result, and the trade deficit has apparently caused a 1 pp decline in our economic growth rate during the so-called free trade era. Over time, this adds up to real money: our GDP/capita could be $20,000 higher than it is now.
And the benefit, we are told, is the capital inflows. As if the United States is a Global South developing country suffering from a capital shortage. We are not. There is plenty of our own money to invest in productive projects. The Wall Street casino & California real estate speculators do not count.
As for the $15 trillion, I think Oren was referring to U.S. NIIP. And it’s actually at $18 trillion now. Historically, when other countries’ NIIP starts to exceed 60% of GDP, bad things tend to happen. The USA is well past that point last I checked…
Jon Murphy
Jan 9 2024 at 11:38am
Citations needed for all of this. Ideally, citations of hard empirical evidence, not more mere assertions.
Warren Platts

Well, here is a chart of NIIP over GDP, percentage-wise. I see it’s bounced up a bit lately, but that’s probably just an artifact of recent inflation.

My guess it that Cass was talking about trade in goods and services. It’s been negative every year since 1976 and amounts to $15 trillion. By debt, I assume he refers to the deficit as an obligation.
Interestingly, RGDP per capita growth averaged 2.3 percent from 1947 to 1976, when the deficits began. From 1976 to 2022, it averaged 1.8 percent.

It’s true. Real GDP growth rate slowed down once the free traders gained political control. Not surprising considering the main equation is Y = C + I + G + NX
Jon Murphy
Jan 10 2024 at 6:40am
If that’s what he meant, he’s still wrong for the reasons listed in the post. Trade deficits do not equal debt.
He just makes this assertion and never supports it. Indeed, it’s such an unclear assertion no one quite knows what he’s referring to.
True, but the claim that the deficit caused slower growth in real GDP has been tested multiple times and shown to be empirically incorrect. Indeed, the slowdown would be greater without trade (see Free Trade Under Fire by Doug Irwin). Further, for the US, the correlation between trade deficits and GDP growth is positive (as trade deficits grow, so does GDP growth rates). Regulation seems to be the main factor slowing growth, as well as a return to mean following WW2.
Trade is an important factor in economic growth, but it is not the only one. There are many factors that matter.

By the way, there is a paper in the October 2023 issue of the Journal of Political Economy called “Labor Market Conflict and the Decine of the Rust Belt.” In that article, the authors find that decline in manufacturing in the Rust Belt is primarily due to labor market conflicts. The authors find:
Now, extrapolating their findings to the manufacturing sector as a whole (which is always dangerous, especially in this case since labor market conflicts existed primarily in the Rust Belt rather than the rest of the country), it’s not likely trade deficits have anything to do with manufacturing employment decline. If the causal story Cass tries to employ is “free trade -> trade deficits -> employment decline” then the timing doesn’t work. The decline in employment was going on long before trade became a factor.
All this aligns, by the way, with the empirical findings that trade has no long-term impact on jobs. Some jobs are destroyed/displaced by trade. Others (and higher paying ones) are created. True, individuals can be made worse off by these changes, as is the case with any change.* But there are already numerous programs in place to help those people, and it doesn’t make sense to close off potential areas of improvement for these folks.
But I am getting long-winded. The point is: the empirical evidence does not support Cass’s claims. The timing just doesn’t match up. Cass needs a lot more than vague assertions, grossly misunderstood claims about theory, and misunderstood quotations to support his case.
*I have yet to hear a good reason why people should be more concerned with changes that occur due to international trade than domestic trade. Indeed, I have seen just the opposite: when a worker loses their job, for whatever reason, they are upset.

And many interrelationships among factors, including trade, and encompassing and extending beyond social sciences. IMO this involves complexity science. That’s why the debate continues and will continue.
Jon Murphy
Jan 10 2024 at 10:35am
Indeed so. I am a complexity economist myself. That’s why the simplistic understanding of Cass, and protectionists in general, is flat out incorrect: they ignore complexity.
The world is a very complex place. That’s why it is so important to get the foundations of understanding (the principles of a field of study) correct. One of Cass’s problems is he builds off no foundation. I’d call it a house of cards, but a house of cards can at least stand without any outside force pushing on it. Cass’s theory of protectionism isn’t even internally consistent.

Accounting can mislead to many with regard to what is really going on with economic activity, and economic exchange. Trade is one problematic area which due to accounting allows for Pols to distort and many in the public to buy in to views that are incorrect. Additionally the old accounting identity of C+I+G+(X-M) is also misunderstood by a great many.
So the question is this: Why has accounting for economic activity not changed to better reflect the underlying activity of exchange that takes place?
Jon Murphy
Jan 6 2024 at 10:45pm
Just because some people misunderstand something doesn’t mean one should toss out the idea. GDP has its shortcomings, but it’s better than alternative methods of accounting proposed.

Triffin’s Paradox: any nation seeking to issue a reserve currency must export its currency in size by running large, permanent trade deficits.
The US chose to be a reserve currency and by extension a deficit country when it promised protection for Saudi Arabia and other Gulf States in exchange for selling oil in US dollars.

Jan 10 2024 at 7:03pm
It’s worth noting that Triffin’s dilemma only holds with a reserve currency on a gold standard. A reserve currency is incompatible with a gold standard (which is entirely true. This was known even at the time of Bretton Woods, but the politicos ignored the economists in the room).
When there is no gold standard, the dilemma does not hold.

I think it is better to look at it from a foreigner’s perspective. Foreigners buy land and financial assets in the US because their own population is older than the US population. Foreigners produce goods today to get goods back tomorrow. The US trade deficit will turn around because the Chinese and Europeans have retired, not because of some US policy. The foreigners will pay for future US goods by selling the stocks, bonds, and land back to the US.

David, I agree with your observations and wonder if you might have a critical opinion on the 2014 IMF changes in Balance of Payments terminology in which the old “capital account surplus” is now characterized as “net borrowing.”
In 2014 the IMF completely revamped the presentation of balance of payments accounts. Items for which transactions represent the exchange of cross-border claims on future income beyond the current year, that were previously grouped into the “capital account,” are now dubbed the “financial account,” and net acquisition of financial assets in these accounts is indicated by positive entries (not negative entries indicative of “capital account deficits” as before. What is more, the net balance of the summed financial accounts (called the “investment position”) is described by the IMF as “net lending” or “net borrowing.” In the 2014 revisions, capital transfers are grouped into an account now called “the capital account,” bearing no relation to the old “capital account.
From the IMF Balance of Payments and International Investment Position Manual, Sixth Edition, (https://www.imf.org/external/pubs/ft/bop/2007/pdf/bpm6.pdf)
133: “The overall balance on the financial account is
called net lending/net borrowing. Net lending means
that, in net terms, the economy supplies funds to the rest
of the world, taking into account acquisition and disposal
of financial assets and incurrence and repayment of liabilities.
(Net borrowing means the opposite.) Despite the
lending-oriented terms, net lending/net borrowing is a
balance that takes into account equity, financial derivatives,
and monetary gold, as well as debt instruments.
Also, net lending includes reduction of liabilities and
net borrowing includes reduction in assets.”
My defense of this nomenclature (from my book The Japanese Economy, 4th ed, p. 189): “The financial account items (like the old capital account as it was once dubbed) include all financial instruments—loans, trade credit, currency, and securities of all kinds, including not only stocks and bonds but also financial derivatives such as swaps and stock options. More than that, the financial account items also include some real assets such as real estate or factories, the ownership of which entails a right to a future cross-border stream of income or services. If a resident buys a factory in a foreign country from a nonresident, she is acquiring an entitlement to the future stream of dividends from profitable operation of the factory. The acquisition of the factory is in that sense equivalent to net lending by the resident to the nonresident from whom the factory was purchased—paying something now in return for a promise of receiving a stream of payments in the future.”
David, has the IMF stoked confusion? Or is the new terminology acceptable? I am on the fence myself.
