Are export controls just trade barriers? Not necessarily. In a new AEA P&P paper, Jingting Fan (CKGSB), Nuno Limão @georgetownsfs , and I study multilateral export control regimes since the Cold War. We find that coordination among members is associated with substantially higher bilateral trade. 1/7

Teaching my @GPS_UCSD students how to get the LLM in R stats to interpret macro data from FRED data API @stlouisfed. Once we got that working, I changed the prompt to write in the style of Game of Thrones.

Interesting policy development: temporarily eliminating beef import tariffs to reduce prices appears to imply the Trump admin does believe tariffs raise prices. Free trade for the win!

Maybe we should all just muddle though like the old times. And if everything is fine, we cancel the Canvas subscription and move on.

So tired of this misinformation. Of course economists understand this. A net capital inflow can be satisfied by running a current account deficit. The question is not whether the accounting identity holds, but which domestic adjustment margin moves: private saving, private investment, government borrowing, or some mix of all three. It’s not a secret mystery only Michael Pettis can illuminate. I taught this in class last month and it was literally on my midterm exam today.
Replying to @michaelxpettis
2/9 He notes in this piece that "the domestic counterpart of its external deficits today is borrowing by the US government." Many economists find this almost impossible to understand. They do not see how net capital inflows can contribute to rising US debt.

The administration's tariffs don't just rest on bad policy — they rest on an outdated concept that no longer fits the world we live in, says economist @KyleLHandley. He explains that Section 122 was written for a monetary order that no longer exists. ow.ly/qut950YLoOC

This is a very strange NYT op-ed. It starts out by lamenting that many entry-level cars are $25-30K today. Then it gets nostalgic about cars in the 1960s costing 1/3 of median family income 1/3 of median family income today (2024) is over $35,000! nytimes.com/interactive/2026…

“Jo Boaler is a professor of education at the Stanford Graduate School of Education, with an enormously influential body of work …. Her work got Algebra removed from middle schools across the Bay Area. It is some of the most incompetently or dishonestly conducted research I have seen in a decade as a journalist.”

.@USTradeRep's Section 301 case says "systemic overcapacity" abroad causes trade surpluses that harm US manufacturing. As @stanveuger @KyleLHandley show in new comments, there's no relationship bt low capacity utilization & big trade surpluses - if anything it's the opposite:

You will be pleased to learn @emilyjblanchard, @KyleLHandley, and I just submitted comments on the Section 301 investigations of acts, policies, and practices of certain economies relating to structural excess capacity and production in manufacturing sectors: aei.org/articles/comment-to-… We explain that the evidentiary framework underlying the investigation is fundamentally flawed.
