Routine for every class now: - sign out previous person who used the system - sign in to AV system computer - verify sign-in with authenticator on phone - wait for phone face ID to recognize - wait for AV system computer to load - kill Microsoft Teams auto-launch - sign in to course system web page

"Fiorenzo Magni is riding to a 2nd place in the 1956 Giro with a broken collarbone. He tied a piece of inner tube to his handle bar and pulled on it with his teeth, since it was to painful to pull on the handlebar with his arms while climbing"

When your dynamic stochastic general equilbrium forecasting model produces a random walk forecast with big standard errors...

Old Troc shit for you Philly folks look at this schedule. Back when I was going to like 3 shows a week. Dead Milkmen, Pavement, GBV, Ween, Dee Lite, and you gotta love the Dinosaur Jr and Sebadoh separated by a week after Mascis booted Lou Barlow from Dinosaur a few years before

"Conquest Lost and Regained: American Inflation in 2020s" with Thomas J. Sargent is now posted: www.dropbox.com/scl/fi/kfymw... After the pandemic, inflation surged in the US. The Fed responded slowly. We use a model where the Fed sets policy by optimizing with a drifting coefficients model.

Moon over palm trees 🌴 on campus this morning. Join us!

Getting an R&R is a good outcome but…

Since I’m recalling Chicago 1st year: After finishing this for Hum class, my roommate executed a perfect drop kick of the book through the transom of the dorm study room and yelled “so glad to be done with this POS”

After posting the Marx quote yesterday a colleague remarked it was a sign of the Chicago core. This course & readings really were transformative thepointmag.com/dialogue/cri...

Greeting the start of the week

Looking forward to participating in the 2025 Macroeconomic Policy Perspectives Conference at the Becker Friedman Institute University of Chicago in October, where I’ll be presenting a new paper with Tom Sargent on the American inflation of the 2020s bfi.uchicago.edu/events/event...

What’s an instrumental that you sing along with? Here’s mine from today youtu.be/59Gy7TAkQW8?...

Foucault’s lectures start just like any class: “In any case, you can come and see me in my office after the lecture if you have questions to ask me. But there is one question …I thought I had already answered it in advance, but I have to conclude that my explanations were not sufficiently clear.”

When I talk with my colleagues around the university, they always remark on how appreciative economists are

A great story out of Chicago: “In 2004, Anish Kapoor, the chief architect of the Bean, stole a baby and put that baby inside the Bean,” one of the protesters said… “We’re calling for the immediate release of the man trapped inside the Bean.” news.artnet.com/art-world/is...

Honored to receive the Miami Herbert Business School PhD Student Mentoring Award. Thanks to @yangivyxq.bsky.social for the nomination and my colleagues for the selection.

You don’t see “Independent Researcher” affiliations very often

A fun result (if your idea of fun is warped): Most models of production networks are static, while I analyze dynamic flows on networks. But for worst-case/H∞ performance & robustness, only frequency zero/steady state matters. (maximum singular value of Leontief inverse)

Ran a loop which somehow was all downhill and ended up underground (underwater?)

Today’s entry

I'll post the paper in a little bit, but here's a preview of some results on the dynamic propgation of stochastic shocks and their worst case amplfication -- which also covers model uncertainty -- over networks. I focus on production networks and information propagation.
