Very cool (and unexpected): my working paper on hospital billing regulations and individual financial health with Yaa Akosa Antwi and Marion Aouad is the featured working paper on the NBER website today www.nber.org

Use the SHED and want an easier way to see all the survey questions over time? Now you can! I've built a new question tracker to show the questions asked in each year of the survey at shed.jefflarrimore.com (1/2)

Twice the normal amount of good news this morning! Crossed off an academic bucket list item with my first NBER working paper (w/ Yaa Akosa Antwi and Marion Aouad) going live this morning: www.nber.org/papers/w35080 More importantly, it was just accepted at the Journal of Health Economics!

Update: I'm 30+ runs in now. Battled Hades x3 times, but not close to beating him. Gameplay loop is great and writing is excellent. Claude Code learning definitely lagging behind.

Probably should be learning more about Claude Code, but Hades is on Game Pass. Thanks @paulgp.com and @economeager.bsky.social.

Do you have a paper on financial decision-making? Want to present research & hike? Does Bozeman in early August sound good? The Financial Decision-making Conference is Aug 6-7! Submission deadline April 20. The call for papers is here: fdmconference.pages.dev#cfp

🧵A thread on "AI one-shot papers". This has not been a focus on Bluesky, but on Twitter/X and LinkedIn, there has been a large discussion of the ability to "one-shot" policy evaluation, which David Yanagizawa-Drott has been pursuing in an interesting way: ape.socialcatalystlab.org

Probably should be learning more about Claude Code, but Hades is on Game Pass. Thanks @paulgp.com and @economeager.bsky.social.

My attempt at articulating why I think LLMs are a clear net positive for all research, and it's a mistake to ignore it despite private concerns: paulgp.com/2026/03/16/r...

The extremely loosely goosey nature of data governance in AI land means that use of some types of confidential data may end up being signals of true human effort. The AI assisted papers that have been demonstrated only work because data is on the open internet and already cleaned/aggregated
