A truly remarkable statement at an incredibly dispiriting time.
Some countries that have prosecuted or threatened to prosecute central bankers for the purpose of political intimidation or punishment for monetary policy decisions: Argentina, Russia, Turkey, Venezuela and Zimbabwe.
Attempting to criminalize the actions of an independent public servant, Fed Chair Jay Powell, for the sin of acting independently is an outrage. It's bad economics, bad politics, bad for the rule of law, bad for the public sector, bad for American credibility and bad for Americans.

There had been a lot of chatter/hope/speculation that we would hear from the Supreme Court at 10am today on the legality of Trump's tariffs. But... they've only posted one opinion, and it ain't the tariff one.

Continue to be uncertain about whether the biggest cause of uncertainty will continue.

A good exercise to do prior to your year-end giving.

I support these three charities that work to alleviate global poverty (in reverse alphabetical order):

1. @unicefusa.org
2. @pih.org
3. www.givewell.org
This brilliant. I've experimented with making similar simulators before, but this from Giving What We Can is so well executed and needed right now... some perspective, and just how lucky we (some of us) are. #charity #wealth #redistribution #fairness #equity #equality

The year before Trump took office, the US averaged +168,000 jobs per month.

It added just 119,000 jobs TOTAL in 7 months since Trump's tariffs began.

The unemployment rate just hit its highest level in 4+ years.

Even Trump's Chief of Staff admits his tariffs hurt our economy.
According to a new court filing, the Trump administration has a six-page list of banned words that Head Start locations are forbidden from using when describing their programs.
Among the censored words: "disability," "race," "women," "trauma," "Gulf of Mexico." Short thread with the full list. 🧵

Households face annual costs of roughly $400–$900 from climate change—mainly from disasters, higher insurance, and energy costs—with lower-income families and certain regions hit disproportionately, from @kclausing.bsky.social, Knittel, and @cwolfram.bsky.social www.nber.org/papers/w34525

Excellent piece from @stanveuger.bsky.social and Clark Packard on why Congress must reclaim their clear authority over the power of the purse.

See Article 1 Section 8 of the US constitution.

This was also a theme of my recent testimony before HWM.

New blog post today on work with @knittelmit.bsky.social and @cwolfram.bsky.social.

Climate inaction is *already* a big expense affecting US households costs; the most important mechanism is the impact of climate-related natural disasters on housing costs.

The image that always sticks in my mind for that total breakdown of the Constitution isn't Jan 6 itself, it's Pelosi literally rallying troops in front of the Capitol to protect Congress from the president.

A good day to re-up this thread on why tariffs are a poor tax policy instrument.

Also relevant today, this broad use of tariffs definitely exceeds the President's authority under IEEPA.

Early indications suggest the court agrees.
🧵 (1/8) My new working paper with Maurice Obstfeld, “Tariffs as Fiscal Policy”, was just posted today @piie.com. Within, we evaluate the new role that tariffs are playing in the US economy.

At least these small businesses are standing up for the integrity of the constitution (and demonstrating the harmful economic effects of tariffs).

Betting market odds for SCOTUS letting Trump keep his tariffs have tanked

And kudos to @kaine.senate.gov and Sen. Rand Paul for making such clear and persuasive arguments.

Watching this terrific event right now @piie.com.

Good to see some bipartisanship on this important issue.

And the results from today's Senate vote on the Canada tariffs & yesterday's vote on the Brazil tariffs.

I was honored to join this important effort opposing the IEEPA tariffs. Huge thanks to @stanveuger.bsky.social for his work on this.
I organized an economist amicus brief in the IEEPA tariffs case the Supreme Court will soon hear.

As a matter of current law, could the president just…knock down the entire White House? Just raze the whole thing to the ground?
we need the national guard for this. it’s an emergency
