I sat in rooms debating how and if to use sanctions. With each use, you know you are incentivizing others to insulate themselves from the U.S. economy and system. You balance this with gains to national interest from using them. No national interest offset anymore, just damage to us over time.

12/In the US, it is unclear what national interest is being served by sanctioning EU officials. Increasingly, it looks like hyper elites (think Big Tech) is driving the bus. The result: an acceleration in the breakdown of transatlantic relations.

Highly recommend this episode from @weisenthal.bsky.social and @tracyalloway.bsky.social . Even if you think you hear / read too much about AI these days, it is both a really fun chat and more importantly one of the better discussions of the practicalities of regulating AI I’ve heard.

This is what I think the goods-producing sector in America is doing right now — “We now have a better handle on what tariffs are doing to our business, and in response we’re cutting staff and/or doing more offshoring”:

The Trump Administration is driving our allies away from us. This hurts diplomatically, but can be damaging to US businesses abroad. US tech firms are a key part of the economy. Reckless trade and foreign policy is endangering our firms long run potential.

This is ridiculous. All G20 members are always invited.The point of the organization is to bring together all major countries regardless of disagreements. Not attending the G20 was dumb. Trying to block a member when we host is a diplomatic train wreck. Hosting G20 is an opportunity. Were blowing it

Trump keeps hailing an investment boom that he says is set to top $21 trillion in pledges from companies & countries. But as we write in today's @bloomberg.com Big Take the reality is a third of that. And even that $7 trillion faces major questions.

Important piece from @msobel.bsky.social & Brad Setser on China’s rising CA surplus and the undervaluation of the RMB. All the attention right now is on US disruption of global trade. But important to remember the imbalance caused by China’s policies & implications for the rest of the world.

Brad Setser & I argue the Chinese RMB is hugely undervalued & call on authorities to let it rise sharply. That's needed to tackle the excessive/massive current account surplus & incentivize domestic demand. 👇

Right now, the Supreme Court is hearing arguments about the legality of the Trump emergency tariffs. Part of the question is their role raising revenue. Separate from legality, we should remember tariffs are a terrible way to raise revenue. More here: www.hamiltonproject.org/publication/...

www.hamiltonproject.org/publication/.... The USG is raising roughly $30 billion a month by taxing imports (tariff revenue). This is a huge tax increase due to Trump’s tariffs. Other rich countries don’t do this because tariffs are an awful way to raise revenue. New explainer from me.

One of the justifications for the Trump administration’s tariffs has been raising revenue: The United States raised roughly $30 billion in tariff revenue in August.

But, in a new explainer, @jaycshambaugh.bsky.social shows why raising revenue via tariffs is bad for the U.S. economy:

I’ve been saying this to people too. The idea you want to be able to host a state dinner without putting a tent on the south lawn is reasonable. But tearing down the WH with no regards for historical preservation or involvement and funding from Congress is truly ridiculous.

The idea of renovating the East Wing into an event space isn't crazy per se, it's been floated before. But a serious version of it, along with doing it legally, would have kept the exterior size of it about the same. Not a massive boxy behemoth bigger than and looming over the White House proper.

There's a world where a president whose term overlaps with the 250th anniversary of independence announces that he wants a WH extension to celebrate. He goes to Congress and gets bipartisan buy-in. Maybe it's part of other big 250th projects with public-private funding. And it's popular. (1/2)
