Discontinuities In Clinical Practice: RD Evidence on Heuristics, Stigma, and Guideline Thresholds

Looks like the ASHEcon 2026 conference agenda has dropped.

Warning: Don't take an early departure flight the last day, or you'll miss a session I'm really excited about.

Not 1, not 2, but 3 (!) papers using RDs to understand physician decision-making.

Great new paper in The Review of Economic Studies using randomized incentives to detect non-response bias, using administrative data to provide ground truth for comparison. While incentives increased participation, they didn't reliably reduce NR bias

Infant mortality increased following the Nazi expulsion of Jewish doctors, according to Helge Liebert and Beatrice MΓ€der in a new REStat paper!

In 1937, sulfa drugs--some of the first antibiotics--were introduced.

This lowered childhood pneumonia rates.

As a direct result, kids with access to these antibiotics...

1 stayed in school longer,
2 had higher incomes, &
3 worked more/had fewer work limiting disabilities.

Antibiotics FTW!

The Tax Nerd Who Bet His Life Savings Against DOGE Until Elon Musk came roaring into the nation’s capital, Alan Cole was largely a plain-vanilla investor.

A tax economist put his entire life savings into a prediction market bet that DOGE wouldn’t cut spending.

His wife read the Kalshi comments from the people on the other side and grew *more* confident because β€œthey didn’t seem to understand what they were buying.”

He made a 37% return

This is also my issue. But I’ve been amazed by how seemingly unpopular it is. Any op ed or Reddit post on this topic gets met with a torrent of β€œwhy don’t you love spending time with your kids?” Or β€œwhy do you want to endanger educators on the roads?” etc.

The joy of rooting for team USA is witnessing excellence through freedom. It’s not an accident that Liu’s skating style, her words, her family’s refugee story, all emphasize self-expression.

(What a blessing it is that the pursuit of freedom is so winning. Shed his grace on thee indeed.)

treatment standards. To the extent that health insurers implement policies that promote evidence-based medicine, they are addressing the key source of welfare loss in our second-best insurance environment.

One thing that fascinates me is that econs tend to take the information asymmetries as given and derive the optimal cost sharing. BUT, as a clinician, I’m more interested in policies that can reduce the information asymmetries. Medicine is not impossibly mysterious. We have diagnostic criteria…

The health care consumption response to lower prices (moral hazard) represents both wasteful overutilization and valuable risk protection.

Optimal health insurance would transfer resources across health states without price distortions. But because health insurance benefits are not health contingent, the reduced prices are a key mechanism for resource transfer across states. Thus…

I am particularly excited about the Acquatella and Marone paper being presented. It formalizes intuition about the value of health insurance and problems with the traditional understanding of moral hazard…

If you put an older patient in an MRI, you'll find about 80% of them have a rotator cuff tear. Most asymptomatic people have abnormalities on imaging. jamanetwork.com/journals/jam...

Real insane part of this clip is Hassett saying in the beginning that NY Fed researchers β€œshould be disciplined” for…writing an economics paper that comes to a conclusion the president dislikes? A conclusion that matches the vast majority of economic evidence on tariffs? Nuts

New dataset dropped this month: national Medicaid provider spending (2018–2024), aggregated by NPI x HCPCS x month. Includes FFS, managed care, and CHIP encounter data. Public, 3.3GB, provider-level detail. Looks very useful for utilization & spending research
