In that case, the subtle problem could be revealed in a comment.

Good point. In the second paper, he considers both types of beneficial MH, including the one you model.
riegerfels.bsky.social
Given these considerations and given that you model med expenses as perfectly divisible, i think that your paper models a de Meza-type of beneficial MH rather than a Nyman type.
riegerfels.bsky.social
For, if expenses are perfectly divisible, you can always afford to spend a little more on meds by reducing other consumption (ruling out corner solutions). Then it's not lack of affordability that prevents you from getting more meds but that you prefer to spend your money on other consumption.
riegerfels.bsky.social
I think a crucial difference between de Meza's and Nyman's ideas of beneficial MH is that the latter relates it to unaffordable medical expenses becoming affordable through insurance. That again requires indivisibility of such expenses.
riegerfels.bsky.social
That being said: The idea that limited savings possibilities (liqu constraints) increase beneficial MH is a cool idea, though.
riegerfels.bsky.social
I agree on its importance. Less on it being surprising given that the idea of beneficial moral hazard is around for several decades now (de Meza 1983, Nyman 1999). There is also already a literature on how it affects the evaluation of public insurance schemes like Medicaid.

In economics, editors, referees, and authors often behave as if a published paper should reflect some kind of authoritative consensus.

As a result, valuable debate happens in secret, and the resulting paper is an opaque compromise with anonymous co-authors called referees.

Hello. I have some work on insurance decision-making and would love to be added. Thank you!

An empirical econ paper needs two things: 738 robustness checks concluding we can’t really ever fully be sure of internal validity in the appendix, and one (1) wild back of the envelope calculation indicating that the result is world-changing in the discussion section
scientificdiscovery.dev
Now I've come across several instances of people writing, essentially:

'Let me provide a very rough estimate. Don't take this number literally, because it has several flaws.'

And then their number becomes cited as the canonical figure on the topic.

Okay, the first Women in Econ starter pack was such a success that we quickly hit the BlueSky starter pack limit (150 accounts). But, I've got a version 2.0 with even more awesome economists you should follow!

We need more women econ professors, and we increase demand for them via measures like implicit quotas or encouragements to apply.

But we will succeed _only if_ we increase supply: train them.

To colleagues in PhD admission: some of these numbers 👇are encouraging, but let's do more.

Thanks to Monica Essig Aberg (who I can’t find on here) posted the gender stats for new Econ PhD Cohorts. You can see who is more balanced vs less and live updates on this google doc #econsky 📈📉

On Tuesday, 36 US ports will be shut down by the largest shipping strike in living memory.

This could recreate the chaotic supply chain crisis of 2021-2022. Are we ready?
