📢Adam Smith, @gautamkamath.com, and I are putting together a list of job market candidates in Foundations of Responsible Computing! Last year's list was a great success so we're keeping it going! If you want to be included, or nominate someone, see link in the replies!

The CFP for ACM CSLaw '26 is up! Deadline for main-track papers (archival and non-archival) is September 30! computersciencelaw.org/2026

BU Econ is hosting the second edition of WERISE (Women in Economics: Research, Ideas, Solutions, Executions). See below for details, feel free to RT/quote and spread the word! x.com/bu_economics...

Universities need to fight the administration in court, rather than settling. Thank you, Harvard! www.nytimes.com/2025/09/03/u...

I am teaching a PhD seminar this fall which attempts to put a decision-theoretic lens (or lenses) on research design. So e.g., statistical decision theory, eliciting beliefs & preferences, and rational benchmarks. Here's a draft syllabus docs.google.com/document/d/1... What's missing?

My Mac laptop now won't let me open text files in a text editor if they are from unknown sources?

How do we establish that we've elicited an LLM's beliefs? Can we apply what we know from eliciting human beliefs, or is it irrelevant given that we can directly access LLM's internal representations? Why do these questions matter? Some thoughts here statmodeling.stat.columbia.edu/2025/08/15/w...

When does it make sense to talk about LLMs having beliefs? statmodeling.stat.columbia.edu/2025/08/15/w...

Thanks to Kangning Wang for working with me on this "A Geometric Analysis of Gains from Trade". There is a very simple geometric proof that the "random proposer" mechanism gives a 4-approximation to first-best gains from trade. And some calculus gives the state-of-the-art 3.15-approximation.

Does anyone have a good reference for paradoxes in set theory? I'm looking for something self-contained.

Dave Patterson (UC Berkeley) points out why public investment in basic research and education is vital, and defunding it is incredibly short-sighted. thehill.com/opinion/tech...

📢Excited to announce: EC'26 📅 When: July 6–10, 2026 🍝 Where: Rome, Italy General Chair: Stefano Leonardi PC Chairs: Alex Teytelboym (@t8el.bsky.social) & Matt Weinberg Hope to see as many of you there! #ACMEC26

I was the AEA's President Elect as the first Trump term began. We worried about government statistics then, and appointed a committee that included members (such as Google's Chief Economist) who might be in a position to help make reliable statistics available if the government went dark. #econsky

Nobel prize winner George Akerlof (my former colleague) on the firing of statistics officials: www.nytimes.com/2025/08/03/o...

Statement from the largest economics association about the BLS firing As context: AEA approximately never makes such public statements This is a big deal

Some say Trump is destroying BLS because he says he doesn't like the "phony numbers." But Chamath knows the truth: Trump is just really mad that firms and households sometimes take too long to answer surveys, which has implications for measurement error, even attenuation bias if on a model's RHS

Congratulations Dr. Paula Kayongo for successfully defending her Ph.D. dissertation! "Behavioral Information Design for Forecasting Dashboards: Equilibria, Mechanisms, and Calibration" Thanks to her stellar committee: @jessicahullman.bsky.social, @mjskay.com, and Annie Liang!

Wow. A group of top scholars at Harvard just sent a letter to its president, Alan Garber, warning against surrendering to Trump. Signatories include Steven Levitsky, Dani Rodrik, Ryan Enos, Theda Skocpol, and Steven Walt. Someone forwarded it to me. Read it here:

Feeling good being a doctor 🙂

We may have the chance to hire an outstanding researcher 3+ years post PhD to join Tarleton Gillespie, Mary Gray and me in Cambridge MA bringing critical sociotechnical perspectives to bear on new technologies. jobs.careers.microsoft.com/global/en/jo...

Good to see some universities standing up for american and academic values. Thank you George Mason University president and faculty.

Congratulations to Dr. @yifanwu.bsky.social for successfully defending her Ph.D. dissertation! "Trustworthy AI: Foundations from Proper Scoring Rules" Thanks to her committee: @jessicahullman.bsky.social, Bobby Kleinberg, and Annie Liang.

New paper (w. Paula Kayongo, @jessicahullman.bsky.social) on bidding dashboards as might be used in online marketplaces (like ad auctions). (a) even bidding against a dashboard, massive under-shading as also observed in auctions. (b) showing direct payoff relevant info improves bidding a lot.

The @nytimes.com says: "The Bull Market for Economists Is Over." www.nytimes.com/2025/07/28/b.... But Oxford Econ Dept & Nuffield College continue to offer their prestigious 3-year postdoc in economics! 👏 🎯 Deadline 🚨 30 September 🚨 to get offer by Xmas 🎄: economics.web.ox.ac.uk/nuffield-pos...

Giving a talk to high school students tomorrow at @sydneycompsci.bsky.social. The part on streaming algorithms is going to be fun!

We have a new blog post up at @materialize.com about analyzing the Bluesky firehose (Jetstream, really) through Materialize. You can grab a copy of the community edition of MZ and follow along, or invent your own ways of looking at the data, live! materialize.com/blog/analyzi...

Harvard, we are counting on you to stand up for American universities and values. www.nytimes.com/2025/07/28/u...

In light of Columbia's capitulation to the Trump regime's illegal and extortionate demands, I have resolved not to write for Columbia publications, speak at Columbia events, or perform other free labor for a university that has repudated its values. 3d.laboratorium.net/2025-07-25-c...

With conferences like AAAI embracing the use of LLMs in reviewing, robustness to subversive attacks -- like hidden LLM prompts in submissions -- is important. Towards this, see the "ElicitationGPT" paper, w. @yifanwu.bsky.social, which gave adversarially robust (aka. proper) scoring rules for text.

At ICML the use of LLMs in reviewing is strictly prohibited. However, now they are saying that hiding prompts in papers to respond to LLM reviewing is also an ethics violation. (Exact texts in thread.) If LLM reviewing is prohibited, then author manipulation of LLM reviews should be ok. Right?

I've been working on a new tool, Refine, to make scholars more productive. If you're interested in being among the very first to try the beta, please read on. Refine leverages the best current AI models to draw your attention to potential errors and clarity issues in research paper drafts. 1/

Thanks for a great #ACMEC25 everyone! See you next year in Rome! In the mean time: 1) Make sure you’re a member of the SIG. 2) Make sure you’re on the SIG email list. 3) Propose special initiatives. 4) Check out SIGecom Exchanges, TEAC, and TheoretiCS!

Spread the word: there is a new prize in Theoretical Computer Science in honor of Luca Trevisan-- cs.unibocconi.eu/call-nominat... (Intent-to-nominate letters due by July 31.)

At the IDEAL annual meeting and saw this paper presented. Basically: reducing length of chain of thought LLM computations by deleting intermediate computations, more like classical functional programming where only function call and return values are important. arxiv.org/abs/2503.14337

Wait, so the United States is now a country where the president threatens business owners who potentially might make contributions to the opposition party? www.nbcnews.com/politics/don...

Dear @divvybikes.bsky.social, please fix your electric bike parking incentives. The station as Davis St is always full. Stop charging electric bikes extra for parking at bike racks next to it, saving the limited slots for non-electric bikes that can't be parked without a station.
