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.

1/7 Martin Wolf, in an important piece on unsustainable current account imbalances, makes a point that most American economists miss: "the counterpart of external deficits tends to be unsustainable domestic borrowing."
via @ftft.com/content/49e38e…
2/7 He goes on to say: "The Keynesian hypothesis looks right: the inflow of net foreign savings, shown in capital account surpluses made big fiscal deficits necessary, because domestic demand in the US would otherwise have been chronically inadequate."
3/7 This, by the way, is consistent with Joan Robinson's argument that trade surpluses are "beggar thy neighbor" when they export unemployment. The difference is that in economies in which credit is not constrained by gold, the alternative to unemployment can be debt.

Bloomberg: "Canada pitched expanding its financial services presence in the Chinese market as the northern nation aims to increase exports to its second-largest trading partner in a push to diversify from the US." bloomberg.com/news/articles/…

The article continues: "Expanding Canadian financial services activity in China is key to achieving the government’s goal of increasing exports by 50% by 2030, according to Finance Minister Francois-Philippe Champagne."
3/12
I am not sure that expanding financial services activity really is key to expanding Canadian exports to China. It might help a little, but what Canadian exporters most lack isn't friendly financing.
This just sounds like the kind of thing a banker would tell policymakers.

"The diagnosis is widely shared," the article notes, as it quotes Yang Weimin, a former deputy director of the CFEAC, that “The reason for China’s low share of consumption in total demand is mainly the low share of residents’ income in national income.”
3/12
This isn't new. A few of us have been arguing for 10-15 years that China's trade and investment imbalances and its soaring debt are all the result of a highly distorted distribution of income in which households directly and indirectly retain an astonishingly low share.

2/6 multilateral trade. So far, this has mainly been conspicuous by its absence."
Of course it has. That's because for all the huffing and puffing, "the world" is not looking for someone to bring order to the world trading system.
3/6 It is looking for someone to stabilize the rising volatility in global trade by permanently absorbing – as the US has done for decades – the bulk of the huge and highly distorting trade imbalances created by aggressively mercantilist policies in trade-surplus countries.

On the centennial of Britain's 1926 general strike, the FT reviews three new books that discuss and explain the events that year. I haven't read them (although I'd love to do so), but it is worth noting what those events tell us about current conditions. ft.com/content/ab0875…

Although most stories of the general strike discuss it in terms of good guys and bad guys (mine owners or workers, depending on your political preferences), in fact both sides were caught up in a structural trap that neither could resolve.

In the 1920s, Britain remained the world's largest coal producer, but it was increasingly uncompetitive with German, American, Polish and Soviet coal. The main reason may have been the seriously overvalued currency (which also undermined British manufacturing at the time.)

2/9 This story was predicted by, and can be explained through, the insights of both Michael Kalecki and Joan Robinson.
In the former case, it illustrates the Kalecki Paradox as it applies to global trade.
