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.

New paper! Expanding public insurance to parents benefits parents and generates spillovers to children, improving their health care utilization. The estimates highlight intergenerational effects relevant for welfare analysis. www.journals.uchicago.edu/doi/10.1086/733364 @michellemmarcus.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...

Please submit, health economists, and share widely!

Has anyone yet run a head-to-head comparison of the different advice that competing AI tools offer for expecting parents and for parents of newborns, infants, and toddlers?

Updated working paper with my KC Fed Colleague Ying Lei Toh examine how past experiences with fraud affect take-up of new precautionary actions (e.g., credit report freezes) in consumer credit markets: www.philadelphiafed.org/-/media/FRBP...

I’m always for more data. But, be careful using the new Medicaid spending data released by the Trump administration. It’s missing a lot of important details and context. www.kff.org/medicaid/wha...

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

I'm teaching a new course at Stern on AI in Finance and opening it up! Syllabus/slides on Github: github.com/arpitrage/ai... Weekly summaries on Substack arpitrage.substack.com/p/1-three-ru... First post is on Amdahl's Law, Jevons' Paradox, and why finance was slow to learn the bitter lesson

Posted a very early stage draft with rock star collaborators. Key question: when we actually roll out AI tools, how do people use them? Do they just defer completely? Does it improve productivity and ability? We look in the medical setting of pulmonary embolisms paulgp.com/papers/Radio...

There’s a paradox around remote work. Jamie Dimon says it will kill productivity, while startups are hiring for remote roles. Who is right? With Abhinav Gupta and Elena Simintzi we try to resolve this dispute Paper: papers.ssrn.com/sol3/papers.... Substack: arpitrage.substack.com/p/remote-wor...

More on dementia & finances: similar to credit outcomes, we see declines on asset side start about 6 years before dementia onset, patterns are consistent with mistakes driving declines, not healthcare spending or spenddown

Since 2018, UW RDRC supported over 150 research projects, including the well-being of seniors and people with disabilities in Social Security programs (SSI, SSDI, OASI). I am proud of the training and research conducted as part of the RDRC, but without SSA as a partner, this research will stall.

NEW: Elon Musk’s team has descended on an already understaffed Social Security Administration, which now faces further workforce cuts and closures of vital local offices. The consequences could be significant for millions of the most vulnerable Americans.

The twins are at a fun stage where they constantly bring me books to read to them. Unfortunately (for me), the only book they bring me is "Wheels on the Bus."
