Our new @nberpubs paper extends Fogel’s social-savings approach to account for congestion and spatial externalities. These forces can change infrastructure priorities. Full explanation in the video below (sound on 🔊). ⬇️

I assume your rhetorical point is that every good MBA should more efficiently include "In which Hogwarts house does the applicant belong?"

A prominent business school asks recommenders to complete an 8 question personality test for the person they're recommending for their MBA. The questions seem just as applicable to determine which Harry Potter character you are. So I made a quiz: treballen.github.io/

This is the interview Donald Trump didn’t want you to see. His FCC refused to air my interview with Stephen Colbert. Trump is worried we’re about to flip Texas.

I have recently received several DMs from both first year grad students and first year assistant professors. The link is not surprising because there is a specific kind of vertigo that comes with Year 1 of grad school and Year 1 of a professorship. It's the gap between who you think you should be and who you feel like you are in the moment, where two worlds collide: The Imposter Syndrome: "They're going to realize I'm just guessing." The Uncertainty: "There is no map for this, and I'm the one driving." For all of those out there, please hear me: the first year isn't a test of your intelligence; it's a test of your endurance through the "I don't know" phase. But I want to go further than just reassurance, because reassurance alone doesn't build anything. That discomfort you're feeling? It's actually diagnostic information. It means you're operating at the frontier of what you know, which is exactly where you're supposed to be in a research career. The people who never feel that discomfort are often the ones playing it too safe with their questions. And the fog doesn't just clear on its own. It clears because you do specific things: you read papers you don't fully understand and struggle through them anyway. You sit in seminars feeling lost and eventually start recognizing the shape of arguments. You write terrible first drafts and revise them into less terrible drafts. The endurance isn't just emotional, it's the endurance to keep doing the work when the feedback loop is painfully delayed. One more thing: there actually are maps. Advisors, reading lists, established literatures, methodological frameworks. The real challenge is that nobody hands you the map. You have to go find it and figure out which one applies to your particular problem. That's a learnable skill, not a character trait. So yes, you are not broken. But pair that knowledge with this: start building the thing you're missing. Find the map. Do the next hard read. Write the next bad draft. The fog clears for the people who keep walking through it. I'm rooting for you.

$38,300,000,000 of your tax dollars. Not for healthcare. Not for education. Not for small businesses. But for mass-detention camps. It’s flat out UNAMERICAN. Nobody can sit on the sidelines — it will take all of us fighting back together to stop this.
Breaking news: ICE expects to spend $38.3 billion on its plan to acquire warehouses across the U.S. and retrofit them into immigrant detention centers that can hold tens of thousands of people, according to agency documents. wapo.st/4rdkbuF

It is so very scary to see them testing these waters. Whatever they can get away with in 2026, they will escalate in 2028. We're at a real tipping point here.
Mike Johnson on Trump calling for Rs to "nationalize" elections: "We had 3 Republican candidates who were ahead on election day in last cycle, and every time a new tranche of ballots came in they just magically whittled away until their leads were lost. It looks on its face to be fraudulent. Can I prove that? No."

This is in violation of so many laws, not to mention any human decency. No wonder ICE wear masks, their families and friends would despise and disown them if they knew.
Leaked video from ICE detention shows 50 people crammed in cell with no beds or bathrooms—including U.S. citizens. "They hit his face. They beat him until he can no longer stand." "They have been here more than ten days without bathing and enduring hunger." "Look how they have us here. Look at what kind of immigration they have us under—people who are legal, people who are not legal, people who are losing their families—they are kidnapping us." ICE is supposed to use holding cells like this only for short-term detention to process arrests—not for long term clandestine "black sites." This video footage was taken at the ICE Baltimore Field Office located at 31 Hopkins Plaza in Baltimore, Maryland.
