Just an absolutely brutal #EconJobMarket, meanwhile it seems like every day on here I am blown away by some brilliant, creative new JMP.
New data on the #EconJobMarket as of Nov 2. Based on total # of job listings on JOE, this year continues to be even weaker (by 11%) than during COVID (2020). 1/many #EconTwitter

completely unserious foreign investment numbers being thrown around by the president
@ericadyork Per @unctadwif total *world* FDI stock in 2024 was $51 trillion & annual FDI flows ~$1.5 trillion. If the US got $21 trillion, it would be 45 times larger than our $467 billion FDI record (2016). & four times the ~$5.5 trillion domestic & reign investment in the US combined.

The Trump administration has put out 28 updates to the tariff schedule this year, more than once every 2 weeks. Means we can’t even use our 2 week sprint cadences to keep our tariff simulator updated, have to much more nimble than that. In fact the Administration frequently

“By admitting that lowering tariffs will lower prices for U.S. consumers, the Trump administration is acknowledging what economists have pointed out all along: tariffs raise prices,” said Erica York. https://t.co/7fVLgMSgJy via @WSJ

The president moved to lower duties on beef, coffee and dozens of other goods, as he looks for ways to address Americans’ concerns about the cost of living.

On "will wealth trickle down", this is the driver: in most important econ region in the world, no housing is being built. SF: 1500 net new housing units/year last 2 years. Population 8% higher than *1950*. Palo Alto's pop unchanged last 10 years, up 20% since *1960*. Insanity 1/2
San Francisco based companies are currently creating the largest wealth explosion in human history While housing supply is totally fixed not just in the short term, but medium term as well There are no major condo projects and almost no apartments being built currently So you

Wait. If lowering tariffs lowers prices, what does raising tariffs do to prices?
🚨 BREAKING: In a major development, Treasury Secretary Scott Bessent confirms the PRICE OF COFFEE will go down after an impending announcement for tariff relief "You're gonna see SUBSTANTIAL announcements over the next couple days for things we don't grow in the U.S. Coffee,

Exciting development in remote medicine. I had seen US startups promoting remotely controlled surgeries, but now we've had a Scotland-Florida demo of a thrombectomy (on a cadaver). Large potential gains from trade in services!
.@TradeDiversion , your thoughts on the future of international trade in medical services? Will robots soon perform these surgeries? How will this affect health in the developing world? What will the price be? https://t.co/QvuBYGdwlg

As the number of gambling houses has grown across the United States, they are no longer the tourism magnets that they used to be, experts say.

Econ seminar culture is built on the assumption that the audience knows something that the speaker doesn't, and that the speaker values that information. A very important thing the audience knows and the speaker doesn't: Is the speaker making any sense at all? If nobody has any

In other words: Where it says Markus Brunnermeier on X, it’s currently not Markus Brunnermeier. Markus is working on getting his account back. And will holler if that works out.

If you're on the econ PhD job market, make a LinkedIn. A good 30-40% of candidates don't have one (or have a shitty one), and the ROI is massive for private sector jobs off the beaten track (i.e. not econ consulting, Amazon, etc.) Low-hanging fruit.
