This is the best paper written so far about the impact of AI on scientific discovery

Great conference

Thank you @CBOE for hosting a terrific academic conference.

For those who want to jump to the frontier in select areas of economics, the AEA has posted the webcasts of this year’s continuing lectures. Thanks much to Lawrence Katz for his leadership and vision in assembling these lectures. aeaweb.org/conference/web…

History in the making. On Jan. 28, 2025, XB-1 officially broke the sound barrier. Flying Mach 1.122 (652 KTAS) at 35,290 ft. over the Mojave Desert, Boom’s supersonic demonstrator jet ushered in a new era of supersonic flight. Watch the full recorded livestream:

💥Introducing openassetpricing!💥 a Python package for easy-breezy access to the Open Source Asset Pricing dataset. Just `pip install openassetpricing` and openap = oap.OpenAP() df = openap.dl_port('quintiles_vw', 'pandas', ['BM', 'Mom12m']) and you've got B/M and momentum.

Thrilled to announce our new paper, The Natural Language of Finance, forthcoming in Foundations and Trends! We explore how #AI, #NLP, and large language models are transforming research in corporate finance and asset pricing. #econtwitter

Happy to share a new paper with the brilliant Anna Pavlova and Taisiya Sikorskaya: sciencedirect.com/science/articl… Our paper began with a puzzle. Here is a short thread about it. [0/13]

rodneywhitecenter.wharton.upenn.edu/2025-summer-sc… 12 more days to apply to our summer school in structural estimation! It's a hands-on course in which you learn how to do SMM and then work on a problem set with your classmates. Open to PhD students in finance, accounting, econ. And faculty.

We’re So Back Wednesday

I think many colleagues have not realised how large the increase in productivity is when using AI. Maybe this will be a wake-up call for them.

Excited to share the program for my second AI in Finance research conference on June 10 at the University of Maryland - Robert H. Smith School of Business! sites.google.com/view/ai-financ… The research focus is on the economic impact of AI in financial markets and applications.

New paper: Since the rise of large language models, there's been a huge shift in academic writing. In 2024, the word "delves" appeared 2,700% more than its historical average, by one account. The analysis suggests that 13.5% of 2024 abstracts were processed with LLMs.

After introducing who is who in oil derivs and how oil algos work conceptually, we are now getting to the meat of the problem and show how to replicate their behavior. Virtual Barrels Quant Talk, Episode 3: How to Replicate CTAs Behavior? youtu.be/tXb_VOn3ibA?si… via YouTube

AI agents are now capable of doing real, if bounded, work. But that work can be very valuable. For example, the new Claude Sonnet 4.5 was able to replicate published economics research from data files & the paper. We need to figure out what to do with it: oneusefulthing.org/p/real-ai-agen…

Finally liberated the Open Source Asset Pricing repo from Stata! 20,000 lines translated to Python. All pass strict tests or have been hand-validated. So tired 😮‍💨 Sorry we've been so slow to post data this year. Just need to close a few Github issues and then it'll be public!

I turned a static plot in a slide on risk in retirement savings into an interactive web app students can fiddle with. Took only 2 hours to stand up with AI.

🚨 The 2025 Open Source Asset Pricing data release is live! This year, we carefully translated the Stata code to Python (30k lines). This makes maintenance easier and shows our commitment to producing the highest quality dataset out there. We also have a few bonus features 🧵
