Hi #EconTwitter,
I am on the Job Market!
My primary fields are Labor, Migration, and Political Economy. My secondary fields are Macro and Growth.
In my 1st JMP, I examine how the global spread of the Internet affects immigrants' socio-economic integration in the US.🧵

Big announcement to the Labor Econ Community: We have created the "Labor Hub" - a platform to exchange relevant info (events, jobs, visits, SI, papers...) - Apply to become a member! Job market candidates especially encouraged to apply! Link: laborhub.ilr.cornell.edu/ Please share!

To the intersection of #EconTwitter and hiring committees — I'm on the #EconJobMarket and hoping to steal a bit of your screen time. My #JMP examines how adaptation to climate change will affect the global population distribution and its implications for welfare. (1/n)
Had a fantastic day @MU_Econ yesterday: superb seminar, energetic faculty and students, and look at this campus 👇 Thanks for having me!
Don't forget to apply for their AP position, deadline is tomorrow! econjobmarket.org/positions/…

Important result from our Google AI x Econ team. Field evidence for pre existing expertise favoring the ability to learn from AI assisted work.
Foundational expertise may be a prerequisite for extracting durable skill from AI-assisted practice, from @davidautor, Tanya Rodchenko, Josh Martin, Zanna Iscenko, Scott Strand, David Pearl, and Melissa Ferere nber.org/papers/w35720

MIT published a brutally honest report on what AI is doing to students.
A committee of professors and students spent five months studying how AI changed learning on campus, and the findings read like a warning to every university on the planet.
Study groups are disappearing. Office hours are emptying out. Problem sets and take-home exams no longer prove anything, because AI can produce credible solutions to almost any written assignment in the undergraduate curriculum. Students who lean on chatbots lose mastery and confidence, and some slip into what the report calls cognitive surrender, reaching for AI at the first hint of struggle.
The numbers are rough. 46 percent of surveyed MIT undergrads use LLMs daily. 90 percent worry about their own overreliance. Undergrads who feel AI makes them replaceable now outnumber those who feel it makes them capable.
The committee's answer surprised me. They refused to fight AI with surveillance. The report calls AI detectors unreliable, says lockdown browsers feel like spying, and warns that policing students builds a classroom atmosphere of mutual distrust.
Instead, MIT wants to rebuild education around the things AI can't replace. That means oral exams, semester portfolios, in-person project work, and a required social component in every subject. The report even floats the idea of rethinking grades entirely, since without a GPA to optimize, much of the incentive to cheat with AI evaporates.
The committee warns professors against replacing undergrad research assistants with AI agents just because they're cheaper, because a university exists to grow people, not output.
The most famous tech school on earth admitted the machines broke its way of teaching. Its answer is more humans, not more software.
These latest PISA trends are grim. But the subject and country variations are curious.
The OECD average reading and science show a gradual decline since the social media age. Math shows a sharper COVID break.
In Ireland: minimal drop in reading and science, but big in math?
Excited to share the @EconomicsUCD seminar line-up for Fall 2026!
As the seminar co-organizer, I am looking forward to welcoming this fantastic group of scholars to UCD Econ for an exciting term of research and exchange.
Shoot me a message if you'd like to come in the future!

Fall terms coming up. How should we modify university teaching to both use AI effectively and ensure students actually learn/don't just cheat their way through? I wrote eight rules I've been using; hopefully useful for you as well. 1/3

The new H-1B tax gets announced tomorrow.
The original $100K tax was ruled illegal. The White House made its successor: a $103K tax on *all* private sector H-1Bs.
Much more drastic than the original: NO EXCEPTION for people already in the US (like grads of US universities) —>

Every college syllabus should include these graphs.
Use AI for homework, you will get it done faster and get a higher grade, and then get crushed on the exam.
It probably happens only once or twice in a lifetime that your Uni hosts one of the biggest econ conferences, like the @EEANews Congress hosted by @EconomicsUCD next week.
I will be there all days, so if you're around let's grab coffee and chat on our beautiful campus👇

Grad student visas limited to 4-years. Extension possible in principle:
dhs.gov/news/2026/07/16/trum…
It's impossible to finish a Physics PhD in 4 years. How hard will it be to get an extension? Will any foreigner still come to the US for a science or engineering PhD?

The #DiD page has been updated after two years!
The site has been substantially cleaned up: code is now better documented, resources have been expanded, list of Stata/Python/R/Julia packages updated, and all Stata code has been revalidated.
Check it out:

Incredible move by the French (cc @KhoaVuUmn) chatgpt.com/g/g-6a20206ca050…
Seeing the rise of agentic research, I wonder if it can reshuffle sub-field choices (of humans)? AI mostly accesses publicly available and pre-existing data (right?) So, experimental, RCTs-development, "admin data" labor, etc. - all will rise (i.e. remain human-dominant)?

Replying to @dm_coluccia @TomanBarsbai
@AlexMYarkin on how the internet changed the migration experience. As access expands at home, immigrants in the US stay connected to origin networks, leading to lower English proficiency and naturalization, but less segregation and higher well-being.
Very excited about the upcoming visit to the @BristolUniEcon for the Workshop on Migration Economics.
Here is the (amazing!) program: baem.info/Program_MIG_26.pdf It's a real honor to be a part of this amazing group of researchers.
