A new paper by the NBER on the McKinley tariffs of the late 1890s claims that the US economy did not benefit from the tariffs, mainly because they "may have reduced labor productivity in manufacturing."
2/11
Tyler Cowen (along with a number of other economists and journalists) argues that this paper is evidence that if the US were to impose tariffs today (or other trade intervention policies, presumably), they too would hurt the economy.
3/11
But this argument makes the same mistake as claims about the similar lessons of the Smoot Hawley tariffs of 1930. It treat tariffs a little hysterically, either as inherently and always bad for the economy, or as inherently and always good for the economy.
4/11
But tariffs are neither. They are simply one of a huge range of industrial and trade policies that work (much like currency devaluation) by shifting income from households (as net importers) to producers (as net exporters).
5/11
To put it another way, tariffs work in large part by forcing up the domestic savings share of GDP. For that reason their impacts on the economy must depend in large part on whether investment in the economy is constrained by scarce savings or by weak demand.
6/11
In economies running persistent trade surpluses, saving exceeds investment by definition, with the very purpose of trade surpluses being to resolve weak domestic demand. In that case policies that further weaken domestic demand and boost savings are not likely to help.
7/11
On the contrary, they need the opposite policies. That is why most economists, for example, call on China to implement policies that increase the consumption share of GDP (i.e. reduce the savings share). China should, in other words, reduce tariffs and strengthen the RMB.
8/11
But the impact of tariffs on deficit economies will be radically different. In that case by pushing up the savings share, these economies can either enjoy more investment and growth, or the same amount of investment and growth driven by less debt.
9/11
The US had been running large surpluses for over 20 years in 1900 and for over 60 years in 1930. It is not at all surprising that increasing tariffs was unlikely to benefit the economy. Surplus countries should implement the opposite transfers.
10/11
Today, however, the US has been running massive deficits for roughly five decades. It should surprise no one that policies that benefit the economy under one set of imbalances are unlikely to do the same under a set of diametrically opposed imbalances.
11/11
That's why instead of pounding the table about whether tariffs are inherently good or inherently bad, we should instead discuss what the conditions are under which tariffs (and other trade and industrial policies) will or won't benefit the economy.

1/6 According to Greg Ip, in the US economy today, "rewards are going disproportionately toward capital instead of labor. Profits have soared since the pandemic. The result: Capital is triumphant, while the average worker ekes out marginal gains." wsj.com/economy/jobs/c…
2/6 And as Marriner Eccles, FDR's Fed chairman, explained in the 1930s, this creates a dangerous illusion. The extent of business profits depends almost wholly on the purchasing power of ordinary people, which in turn depends on wages.
3/6 In a rapidly-growing developing economy, with huge unmet investment needs, it may be possible (even necessary) for profits to rise faster than wages because the resulting rise in saving can be deployed to productive investment.
1/5 Reuters: "The EU should consider either an unprecedented 30% across-the-board tariff on Chinese goods or a 30% depreciation of the euro against the renminbi to counter a flood of cheap imports, a French government strategy report said on Monday." reuters.com/world/china/fr…
2/5 I think it's only a question of time before the EU will intervene in its external account to protect its manufacturing sector, just as China has done for decades and the US is increasingly trying to do. It can implement all the reforms that have been proposed to improve...

This may sound counterintuitive at first, but I have a piece coming out soon in Engelsberg Ideas explaining why.

“Without a strong turnaround in total factor productivity and a meaningful expansion in household consumption, it will be difficult for China’s economic growth to reach 4 per cent or higher,” he added.
3/11
A 2-3% growth rate is becoming an increasingly popular reference growth rate for Chinese analysts. I'd argue that over the past several years, 2-3% has actually been the upper limit of growth once we strip out the "positive" impact of not recognizing bad investment.
1/8 Jason Furman: "A weaker dollar may improve the economy’s long-run balance, but it does so by forcing Americans to cut back on spending. That is like telling children to eat more spinach today so they will be healthier in the future." nytimes.com/2026/02/03/opi…
2/8 Furman is right. Currency appreciation reduces consumption costs in the short term by making imports cheaper, but in a hyperglobalized world, it also undermines domestic manufacturers by making them less competitive against foreign manufacturers.
3/8 Academic economists (mainly in the US) will argue that this is a good thing because the goal should be to maximize consumption, but the only sustainable way to maximize consumption over the longer term is to maximize production. ft.com/content/89110b…
1/4 Yicai: "China's macro leverage ratio – a measure of total debt relative to nominal GDP – rose by 11.8 percentage points to 302.3 percent in 2025, exceeding the 10.1 point increase recorded in 2024, according to a new research report by CASS. yicaiglobal.com/news/chinas-de…
2/4 There is a lot of disagreement about the real debt-to-GDP ratio in China, especially given the difficulty of counting hidden debt, along with an "abnormal" rise in payables and receivables that reflects inability to pay debt more than it reflects rising revenues.
3/4 If we use the official total social finance number as the measure of debt, the ratio is 315%. The BIS and other entities show even higher ratios. But whatever the real number, it is among the highest in the world, perhaps exceeded only by Japan among major economies.
