Workshop on Marketplace Innovation The home page for the annual Marketplace Innovation Workshop.

[March 16 11:59pm ET] MIW 2026 Submission Deadline

The Marketplace Innovations Workshop is on May 18-20. The submission deadline is March 16. I'm not an organizer, but I really like this venue. It's virtual, and excellent. Hoping to see lots of great papers! marketplaceinnovation.net #socialcal

New course on generative AI for behavioral science | Statistical Modeling, Causal Inference, and Social Science

A few people have asked for the syllabus from my grad seminar on Generative AI for social science -- just posted it here:

That's a surprise! 🀯 If there is information in law abstracts that isn't in the papers then, I agree, having AI come up with that would be quite different then if there isn't. (But yikes, that style choice!)

I do agree that the exercise of writing the abstract can be useful in one's own understanding. But, that is not what an abstract is for. I'm even happy to concede that if you can't, then you don't understand the paper. But, that's not what an abstract is for.

E.g. unconditioned on the technology. Maybe right now AI abstracts are lower quality than human abstracts. If so, I expect it to be short lived.

I'm going to disagree with this unconditional statement. E.g., on unconditional quality. An abstract does not add any new knowledge. Instead it gives a reader a concise summary of methods, results, etc. so they can ascertain its relevance. Readers want the best version of this. It could be from AI.

Economists don't have the problem of numeric citations. They use author-year which are good for identifying the paper, but per the study above, not perfect for equity.

Tl;dr: Empirically authors that appear at the top of the alphabet do better. The certified random system replaces the space between authors with an r with a circle around it.

The economists also use alphabetical, but studied its inequity and tried random, see this paper:

"Certified Random: A New Order for Coauthorship"

The system is usable. I tried it with a series of papers. I like it, however, until norms change, it's awkward.

In 2005, back with @lance.fortnow.com wrote that blog post, citations in CS were all numeric. I hope he would have the good sense now to prefer author-year citations and \citet where the citation is used as a noun. Which, importantly, do not require flipping to the end.

@pkrugman.bsky.social raises a vital point.
At $1 billion/day, six weeks of the air war on Iran would cost as much as a year of US military support for Ukraine. Which would do more for US national security?
The answer may be debated, but the question is essential for America.

If you are a senior researcher (i.e., associate prof level or later), and you're interested in moving to the University of Waterloo (best CS program in Canada) for the Canada Impact+ Research Chair (biggest chair position in Canada, $$$$$), email me. Discretion guaranteed.

Pragmatic & actionable interpretability are buzzwords arguing for mech interp to study concrete tasks.

It's the right instinct, but still underspecified. What counts as a concrete task? What's upper bound on performance? What do users need to know? Decision theory has answers!

I'll be honest, while I really enjoyed #NeurIPS2025, the sheer scale made it hard to get a ton of scientific value out of it.

Looking forward to attending more small and intimate events like #ALT2026 and #FORC2026, where one can engage deeply with the pertinent communities.

In papers studying empirical outcomes of AI in various situations, e.g. game theory, the *first thing* I want to know is: What in the study is still relevant on completely different models with superior abilities? Research must still be relevant next week. I won't read if the paper doesn't say.
