Great to see this write-up of my microeconomics textbook w/ Sam Bowles. It was published in July by @OxUniPress You can see details & free pdf at my website here: simondhalliday.com/microecon… or at OUP here: global.oup.com/academic/prod… Some Endorsements quoted below. 🧵 (1/8)
A new #economics textbook by SFI Prof Samuel Bowles and Simon Halliday (@BristolUni) upends convention and offers a new, more engaging way of teaching the subject — one that actually acknowledges #inequality, #climatechange, #sustainability, and #poverty:
santafe.edu/news-center/news…
In my classes:
- oral exams
- sit-down finals
- team video assignment; students go somewhere together
- in-class short writing (8-15 mins)
- in-class no-AI brainstorming tasks (improve w/ AI)
- projects with AI-use & in-person interviews w/ me
- project presentations,
Etc
This thread is ridiculous.
College profs are innovating like crazy to keep students motivated and learning. All around me they are experimenting, sharing, learning.
Not easy, when AI capabilities improve every semester.
Tyler seems mad that unis don’t have a magic wand to make the problem go away.
It’s a hard problem, we are proving up to the challenge.

I’m acting as a mentor for this program. Please do take a look and consider donating if you’d like to help South Africa develop its econ PhD pipeline.
When the US tariffs landed, South Africa found it did not have enough trade economists to advise its own government.
That is what a thin pipeline costs, and it is a fixable problem. $15,000 funds one student for one year: full-time honours study, a @StellenboschUni mentor and an international one, two weeks of PhD-level courses each November, and a real shot at a doctorate at a top department abroad.
Every dollar goes to the student. Stellenbosch carries the cost of running the programme. No fees, no overheads.
We already have the applicants. What we need is the bursaries.

This is an extremely odd first endorsement to make. Haley Stevens would likely be an excellent defender of university research and teaching. This signals to people that the AAUP is not about protecting higher education, but random extreme left causes.
The gateway course for the moral & political economy major at JHU @HopkinsCES in @SNFAgora “social theories of the economy” involves students reading 100-200 pages per week of hard material; students appreciate the high expectations & training in reading social theory & pol Econ.
This one hits like a gut punch:
Austin Sarat, my favorite college professor, pens a fierce OpEd on @AmherstCollege students’ inability to read challenging texts.
He rightly pins blame on “a K-12 system that has quietly stopped asking them to finish books at all.”
“This past term, I enlisted a few colleagues to teach a short course called “Why Read?” We spent three weeks working through essays on the value of reading by scholars like Martha Nussbaum and Edward Said. What struck me wasn’t students’ lack of interest — it was how unevenly prepared they were even to attempt something long and difficult.
It was clear to me that the students had very different approaches to and comfort with reading difficult material. I tried to help them see that when it comes to reading, similar to physical exercise, the most benefit comes with the most exertion. Reading longer things requires patience and attentiveness, it cultivates the capacity to follow an argument or a plot, and it requires sustained effort to decode meanings.
Surely, this single course won’t end students’ entrenched habits and reverse their retreat from reading. But before we ask our students to read difficult material, those of us who teach in college owe it to all of them to explain that reading books in their entirety matters. If we won’t, or can’t, then higher education will have a bleak future.”
I used to teach this paper because it was in a textbook I used & students liked it. After various events, I showed students “crossed out” versions of papers I didn’t trust any more; this was one of them, even though I didn’t know if it specifically was a part of the pattern. Sad.

Just back from a great workshop co-hosted by @rootsofprogress and @SNFAgora. Thanks for organizing, @jasoncrawford. And thanks for moderating the discussions, @simondhalliday.
I'm not on the hiring committee for this, but I have worked closely with CORE (I'm on the CORE Editorial Board and working on a new CORE textbook). I'm happy to field questions related to it from credible candidates. @sndurlauf @sfiscience Please RT if you wouldn't mind :-)
We're hiring a Postdoctoral Research Fellow in Economics Education and Inequality, jointly hosted by CORE Econ and the Stone Centre network.
12-month position starting September 2026.
Deadline: 22 May 2026.

One of the things we’re doing at @HopkinsCES and @SNFAgora is thinking through what education and pedagogy around progress, civics, and the C21st look like. Really happy to be a part of this collaboration.
Replying to @rootsofprogress
Three keynote course presentations:
-- @Afinetheorem (U of Toronto): Progress, or How Big Things Get Done
-- @simondhalliday (Johns Hopkins): New first-year seminar on progress
-- @matthewgburgess (U of Wyoming): American Economic Success
Other talks and discussion sessions on law, regulation, and abundance; maintaining progress; industrial policy; progress in medicine, and more.

I really think that the public's understanding of how data centers physically interact with their communities is bordering on a low level mass delusion. The actual numbers and impact just do not at all bear out how people feel about them.
In the original paper, this video comes to mind (post hoc ergo prophet hoc in the West Wing). youtu.be/HL_vHDjG5Wk?si=hGyE…
See Kai Gehring’s piece as recognizing this concern.

What if the most important thing an economics research lab could produce was not a paper but a novel?
Karen Jennings wrote First of December as a writer-in-residence at our lab, @LEAP_SU It follows three people in the final days before slave emancipation at the Cape in 1838. The aim was to carry research on Cape Slavery far beyond the academy.
South Africa’s history of slavery remains locked up in archives that almost no one opens. What would it take to resurface it in everyday conversation? A novel might do the work that no academic paper could.
First of December will be released in the UK on 26 March and in South Africa in August.

I have to hand it to anti-medicine influencers. They are very, very, very clever about bullshitting their audience.
Statins are a popular drug, with a low side-effect profile for most patients, which have been repeatedly shown to reduce the risk of cardiovascular disease, the most common cause of death in most developed countries.
So, how the hell do you argue against statins? By creating a highly specific scenario and reporting the benefit in extremely tendentious terms.
More than 90 percent of people who have a heart attack don't die of a heart attack within the next 5 years. So if you ask "how much extra life will a statin give you in those 5 years?" the answer will be small. You can make it seem like statins don't do anything by analyzing their life-saving effect within a population group that mostly isn't going to die, anyway!
The below is like saying, "if you wear a bike helmet for a year after being in a bicycle accident, it only increases your life expectancy by 19 minutes." Well ... haha, yeah! You have framed the scenario in a perfect way to make bike helmets look worthless! Very clever!
Dr. Aseem Malhotra: "If you take a statin for 5 years after a heart attack... in that 5 year period, how much would you think or hope it would add to your life expectancy?"
Joe Rogan: "25%? 30%?"
Malhotra: "Just over 4 days."
Readers added context they thought people might want to know

File under “yet another reason my courses include oral exams” (yes I know I’m privileged to have classes small enough to manage this). Also that’s not the only thing I do but I do think they should be more widely adopted.
As @alexolegimas noted in the comments, if your class is set up such that this is a problem, you haven't been paying attention. We're in year 4 of "stop giving take-home assignments that matter". But also: AI can let you run a much *better* course than pre-AI! 1/2
