New from @abhiecon and @The_Budget_Lab: immigration policies affect entrepreneurship and productivity growth. Even assuming a return to baseline immigration in 2029, the current slowdown in immigration will likely have long-run impacts on business formation and productivity. 1/

[Stan Veuger @stanveuger]

“A new analysis suggests that more than 100,000 children have been separated from their parents during the Trump administration’s immigration crackdown. And roughly three-quarters of those children… are likely U.S. citizens”

Brand new briefing paper w/@AlfredCObregon makes the holistic economic and legal case against the Trump administration's use of Section 122 tariffs. https://t.co/xWlArtMZ5h via @CatoInstitute @CatoTrade

New @nytopinion: "I first met Jerome Powell, the departing head of the Federal Reserve, in late 2011. I was working for Barack Obama, and Mr. Powell was interviewing for a job as one of the Fed’s governors. He was not our first choice. To be honest, he wasn’t even our second."

[Kimberly Clausing @KClausing]

More good news for the rule of law (re. tariffs). So happy to join the efforts of @stanveuger on the amicus brief.

[Stan Veuger @stanveuger]

The Section 122 tariffs are unlawful, as well.

[Kimberly Clausing @KClausing]

Good news for global cooperation! This effort will help develop and strengthen domestic carbon pricing policies.

Brasil preside encontro histórico da Coalizão Aberta de Mercados de Carbono, criado na COP30 em Belém. Com adesão da China e União Europeia, além de outros 10 países, ação promete contribuir com a descarbonização da economia.

Huge congrats to @JustinWolfers on his new project; this @nytimes piece has a good introduction.

This effort will expand his reach in teaching the world economics. I wish him every success.

[Justin Wolfers @JustinWolfers]

A funny thing happened on the way to launch day.
The @nytimes wrote about Platypus Economics. Brian O'Keefe asked tons of questions, interviewed all sorts of folks, and produced something I'm a little stunned by.

Yesterday, Trump lifted UK whiskey tariffs that were supposedly (by law) about a "balance of payments" crisis.
Today, he's imposing EU automotive tariffs that were supposedly (by law) about "national security".

It's all so manifestly ridiculous.

[Jason Furman @jasonfurman]

Excited to be starting as Director of the Mossavar-Rahmani Center for Business & Government at the Harvard Kennedy School.

M-RCBG has been a terrific hub for work on economic issues from macro to regulation to health to climate and I look forward to building on that great work.

[Kimberly Clausing @KClausing]

Me too.

[Gita Gopinath @GitaGopinath]

I hope Powell stays on the FOMC till the end of his term in 2028.

UPS confirms it will automatically send its customers any IEEPA tariffs they paid - once it receives a refund from the government: https://t.co/vI9On9I8LC

Analyzing climate change, international trade, & international taxation, @KClausing finds adequate incentive mechanisms are pivotal to resolving global collective action problems, & could strengthen collective efforts in the face of would-be spoilers. https://t.co/4HGdDCc4Pp

[Kimberly Clausing @KClausing]

(6/6) At present, the world needs collective action around the problem of collective action. Coalitions of the willing can show the way forward, but it will require both pragmatism and a lot of work, as pointed out recently by Canadian PM Carney.

[Kimberly Clausing @KClausing]

(1/6) 🧵 My new working paper is out today @PIIE, comparing three global collective action problems that occupy my recent scholarly work: international tax, climate, and world trade.

I look at both the nature of these problems, and lessons for progress in times ahead.

[Kimberly Clausing @KClausing]

(5/6) Such mechanisms have the potential to fuel cooperative solutions to global collective action problems, and they can also strengthen coalitions in the face of disruptive “spoilers”, a policy problem that may be particularly salient today.

[Stan Veuger @stanveuger]

Simon Johnson and I have a new article out at @thedispatch, explaining why Section 122 does not authorize the administration's latest round of worldwide tariffs.

Me talking to @aduehren in the New York Times about some of the issues with recent middle-class tax cut proposals.

The folks who’ve been hurt the most by Trump’s agenda—low-income people—wouldn’t benefit and their cost could hamper attempts to reverse those Trump policies.
