Forget 2016, it’s 2006 energy here

Great cogent post on the issues of agentic coding (Eg our buddy Claude Code) and the spillover costs on everyone else lucumr.pocoo.org/2026/1/18/ag... @gmcd.bsky.social hits on the things you were complaining about

I probably am not using it right but if I wanted a directory full of verbose, broken code I could do that myself instead of Claude Code.

much better than the default “discover” feed imho

Community college enrollment has been declining since 2009/10. The optimal policy response to this depends on the root of this decline. I'm thrilled @nber.org today released my working paper with Harvard PhD Joe Winkelmann titled: "Labor Market Strength and Declining Community College Enrollment"

Anyone wishing to pontificate about changes in the demand for a college education should be forced to stare at this graph for a bit first

I (vibe)coded a game to teach my Prin of Microeconomics students the difference between one-shot and repeated games and how cooperation in repeated games can work. Try it and let me know if anything is broken :-) dashing-travesseiro-939e66.netlify.app Next: Balatro-style game theory roguelite?

Another successful history mini-conference within a conference! (Including a trip to a pirate bar!)

If you are at the Southerns, come say hi and listen to some interesting economic history presentations! We will be in room “Edison” all day today

Hi #EconSky, I'm on the #EconJobMarket! My JMP provides the first evidence on how teacher labor market shocks affect long-run student outcomes. I study one of the largest teacher supply shocks in US history, larger even than Covid or the Great Recession. Let’s talk about WWII… 🧵

Check out this important and well-done paper! I saw it first at history SEAs sessions a few years ago and it has only gotten more interesting since then And Danielle has more cool projects in the pipeline (I'm biased, perhaps...)

👋 I'm Danielle, and I'm on the #econjobmarket this year! Let's start with a student describing her segregated school: "The school felt temporary. Built like a warehouse with aluminum siding . . . I had a slipshod education" The twist? The student is white, and her school is private. A JMP 🧵 -->

excited to help push Noah's thesis forward into this new working paper! a Miami tradition! (send us your students who could benefit from an MA degree!)

I'm helping co-organize ~5 history sessions for the SEAs again! Submit here: forms.gle/vpYEgEaYtCtd... Great venue, especially for earlier stage work and for grad students. Please submit!

I really liked this idea of using a histogram as a legend in a choropleth map (since land isn't unemployed; people are), so I made a little guide to doing it with #rstats, {ggplot2}, and {patchwork} www.andrewheiss.com/blog/2025/02...

Miami Econ is now part of the Bluesky world! We are excited to join! Help us spread the word!

was tinkering with some OCR and decided to update an old econ history OCR example. What a difference a couple of years makes: old: github.com/apoorvalal/h... new: github.com/apoorvalal/h...

Duolingo accidentally killed Duo the app as well (and my productivity this afternoon)

Timely paper on some of the bad things that happen when Federal grant supported work needs to pause

Woodrow Wilson’s resegregation of the federal government didn’t just harm Black civil servants, but also their descendants across generations Peep the Aneja and Xu (triple diff with matching using census microdata) www.nber.org/system/files...

If you have to deal with (large) csv files a lot, you should give csvlens a shot. Think less for csvs. github.com/YS-L/csvlens

I had lots of questions about the amazing and confusing NBA finals scenes in How to Lose a Guy in 10 Days (secretly a great basketball film, it is nearly the frame of the movie) Luckily @rodger.bsky.social did the deep work for me in 2020 www.theringer.com/2020/07/06/n...

What do we think Indiana Jones’ teaching load was? 1930s at a selective LAC?

In retrospect I’m stupid, but I thought the Gideons actually stayed in lots of hotel rooms and left bibles and it was just loosely tolerated

Discovered a new feeling of dread after seeing a daycare email with the subject “next week is spirit week”

there is an exam question in here somewhere

Deaths by age, sex, and state (1870) #skycharts

US Public Debt, 1791-1870 #skycharts

I did not go up to 20M, but this should give you an idea... (normal reg obviously runs out of memory) I have not looked into the guts of these methods, but I am fairly confident that they use the same FWL matrix transformations, which do not get much more intensive as the number of FEs grows

Very useful benchmarks. I’ve been pleasantly surprised with the new areg but reghdfejl is my go-to when I can get it to work Would love to hear what people do in R/python as well as I move more of my workflow there

In my causal inference class I borrowed an assignment from @nickchk.bsky.social who borrowed the idea from @peternka.bsky.social. It asks the students to apply DiD to google trends data to examine if COVID lockdowns caused an interest in sourdough bread. I had fun coding up the answer key today

Back in DC for SEAs, hope to see lots of you there!

Does anyone who follows me know anything about quantum computing? Miami leadership is pushing for a BS in Quantum Computing and I have the feeling that a lot of this is still hype. We keep getting told about X billion dollars in the next Y years but my skeptic alarm goes off.

We put up the Christmas tree up yesterday. Embrace the holiday creep.

Holy crap this is an astounding piece of historical research Will post ungated link later today unless someone beats me to it www.nber.org/system/files...
