"Free trade is perhaps the closest thing to a universally held value among economists."

The problem is not that "free trade" is in fact a bad thing. It is that most economists don't seem to have a sense of what "free trade" actually looks like.

In a world of free trade, countries exports goods in which they have a comparative production advantage in order to pay for the import of goods in which they don't. Trade, in that world, is broadly balanced, and international capital mostly funds trade finance and...

direct investment in developing countries with high investment needs. In that world, no player, including any government, is strong enough to impose distortions on the global trading system that shift trade away from comparative advantage.
4/16
It's debatable whether this has ever been the case in the past 300 years, but it certainly is not the case today. Our current trading environment is one in which some countries aggressively obtain competitive advantage (which is not the same as comparative advantage)...

at the cost of weak domestic demand, and use trade surpluses to export their domestic demand deficiency to their trading partners. We live in a world of massive trade imbalances that are extraordinarily far from the free trading world of "Econ 101".

The global economy must always balance, which means that global economic integration often comes at the expense of national control over the economy. In our hyper-globalized world (Dani Rodrik's phrase), this also means that countries that retain...

open capital and trade accounts automatically import their trade and industrial policies from those of their trade partners that aggressively manage their domestic economies behind closed trade and capital accounts.

What most economists mistakenly call "free trade", in other words, is the role the US plays in absorbing and balancing industrial policies and trade intervention in other countries. The weird irony is that if the US were to impose policies that reversed...

the impact of trade intervention abroad, this would actually bring the global trading system closer to free trade, even as most American economists would declare that these policies push both the US and the world further away from free trade.

This, by the way, is not so much a criticism of "economists" as it is a criticism of mainstream US and US-educated economists. Those of us who have spent our lives and careers outside the US don't find nearly the consensus that exists among US economists on trade.
11/16
So when the NY Times cites Jason Furman as saying “Everyone in this room agrees with your book. No one outside of this room agrees with your book,” it should be understood that "in this room" is not the economics profession but rather mainstream American economists.
12/16
Outside of the US, and certainly in China, where I live, it is widely accepted that trade and industrial intervention can promote or even create industries. If that weren't the case, every country would embrace completely open trade and capital accounts, and yet so few do.
13/16
Economists often sneer at the stupidity of those who aren't formally trained economists, but where does this arrogance come from? It is not as if economics is a science that attracts the best and the smartest, and that everyone else with skin in the game is an idiot.
14/16
I don't want to be rude, but in my day (and probably today too), after they graduated, most of the smartest people in the top schools went into science, Wall Street, medicine, policymaking, law and high tech, and not into PhD programs in economics.
15/16
When so many of these people ("no one outside this room") are in such disagreement with everyone "in this room", it requires the arrogance (and the internal politics) of late medieval theology to maintain confidence in the beliefs of those in the room.
16/16
I would argue that if economists really are concerned about the fact that they have lost so much credibility, one solution might be to consider the conditions under which their Econ 101 models are wrong and "everyone else" with skin in the game might be right.

Gillian Tett: "Indeed, as an IMF blog recently noted, there are already signs that many non-American central banks are diversifying away from the dollar — albeit very slowly and modestly from a high base, and mostly into minor currencies."

I wish this were true, but I doubt it. If you count not just the official reserves of central banks but also hidden reserves held by state-affiliated entities, and certainly if you include all non-US entities, The amount of US assets held by foreigners is rising, not falling.
3/7
How do I know? Because net foreign purchases of US assets are simply the obverse of the US current account deficit, and both have been rising in recent years. Foreigners own more US assets than ever.

FT: "China’s government bond market has opened 2025 with a clear warning for policymakers: without more determined stimulus, investors expect deflationary pressures to become even more entrenched in the world’s second-largest economy."

In fact China does not need "more stimulus" nor even "more monetary easing" to boost inflation and raise bond prices, nor is that what the bond markets are saying. On the contrary, a quick glance at the debt numbers shows that China has had...
3/7
plenty of both, and rather than raise prices, years of more fiscal stimulus and greater monetary easing have in fact accommodated a weakening consumption share of GDP, bigger-than-ever trade surpluses, and disinflation.

FT: "A cheaper renminbi would help Chinese exporters remain competitive in the face of higher tariffs in the US, but it could also leave China open to the accusation of currency manipulation, a charge levelled by the previous Trump administration."

It seems that traders are betting that the combination of an increasingly sluggish Chinese economy and a potential rise in US tariffs will force down the value of the RMB.

But I think this is a much more complicated issue than these traders might think.
3/10
One complication is that devaluing the RMB in response to US tariffs means retaliating not just against the US but in fact against all of China's trade partners. This might simply increase the incentive for the rest of the world to implement tariffs.

certainly be disruptive for workers in the short term, it is rising productivity that makes a country richer, and automation is a necessary part of this process.

The real problem for workers and overall employment is not automation but rather income inequality.
3/6
That's because while automation increases the productivity of workers, as long as that increase is reflected in an overall rise in wages, higher-paid workers will continue spending as much money as ever on consumer goods and services.

There were more signs today that domestic demand in China isn’t recovering. In spite of all the huffing and puffing over stimulus spending, consumer coupons, and shopping events, CPI inflation in December was flat month on month.

english.news.cn/20250109/da842…
2/4
Although this was much better at least than the -0.6% and -0.3% changes in November and October, it represents nonetheless the fourth month of zero to negative price changes.

On a year-on-year basis, CPI inflation was 0.1%, in line with expectations.
3/4
For 2024 as a whole, CPI inflation came in at a very meager 0.2%, the same as it was last year and the lowest since 2009. For all the stimulus and the surge in debt during the year, in other words, China has been unable to revive inflation.

consumption of the imported good and a production subsidy for its domestic supply", and of course I fully agree. A tariff is just an industrial policy that works by taxing consumption and subsidizing production. In that sense, it is a lot like devaluing the currency.
3/8
But that is also why I only partly agree with him when he says "Like all barriers to market exchanges, tariffs create inefficiency."

I would argue that, like with currency devaluation, it depends on the underlying conditions.
