I mean this here. Hope this is helpful.

Not sure what the source of this could be, but the 2 edges forming the X at bottom of figure have the same visual edge weight but the written weights differ by a factor of two, so something must have gone wrong somewhere, I reckon.

So let me know if you want to come to a virtual talk next wk on “Reimagining Leadership.“ Time tbd. The focus is on cultivating critical, creative, and caring capacities in medicine, but I think it applies beyond that. I’m pretty sure we can do this without any leaders.

Ruha’s title slide for “Reimagining Leadership” with a quote by Saidiya Hartman: “Care is the antidote to violence.”

You either purchase your own toga (including the hat), which is tailored according to very specific requirements, or you can also borrow a gown—university has hundreds in a dedicated wardrobe.

Aw, thanks Ioana. It was just as nervewracking as it was wonderful, but with every day that passes, this asymptotes to "just wonderful".

New working paper: the Norwegian wealth tax was a huge success. The "exodus" of wealthy people never happened (less than 100 individuals left). Tax revenue increased by 71.5%. No changes in business activity or investment.

Taxing Entrepreneurial Wealth: Evidence from
Norway, 2021-2025
Marius A. K. Ring
WORKING PAPER 35854|
DOl 10.3386/w35854
ISSUE DATE October 2026
Whether imposing higher taxes on business owners adversely affects business activity by constraining investment and inducing capitalist flight is a central question in the ongoing debate on how to tax the ultra wealthy. To shed new light, I exploit a series of related Norwegian reforms during 2021-2024 that increased dividend tax rates, removed migration-related capital gains tax loopholes, and nearly doubled the effective marginal tax rate on business wealth. These reforms spurred international debate and, allegedly, an "exodus" of Norwegian billionaires (Financial Times,
2023). While I document clear effects on migration, these responses are concentrated among the top 0.1% of the wealth distribution and mostly confined to 2022 and 2023. My results indicate that at most 100 individuals left due to the reforms. I find no evidence of significant outmigration or reduced inflows of startup founders or inventors. I estimate that absent any outmigration, wealth tax revenues would have increased by 75% from 2021 to 2024. Reform-driven outmigration lowers the revenue gain to 71.5%. My findings further show that outmigrating owners' firms remain economically active and do not reduce investment. In a broader set of analyses, I examine whether business outcomes are affected, regardless of whether owners outmigrate, since firms may reduce investment both due to liquidity constraints or distortions to owners' savings decisions. I compare firms owned by Norwegian individuals subject to the wealth tax with firms owned by foreigners and other tax-exempt entities. By merging historical ownership data from Orbis with the Norwegian shareholder register, I perform these analyses on both Norwegian and foreign-domiciled firms.
Across settings, I find no evidence that Norwegian-owned firms pay out more dividends or invest less after the reforms,…

“One of the main reactions to that report was people [complimented] me for my courage. You can imagine how surprised I was. Why would you need courage to speak the truth. You interpret the law. You look at all the facts, so it’s an impartial decision.”

It’s sort of your professor speech!

@eikofried.bsky.socialOct 9, 2026, 1:42 PM

Had my inauguration on Monday and was overwhelmed to see so many wonderful people there. Thank you to everybody who made it; for all your wonderful wishes; for donating to Doctors without Borders; and also for ignoring my wishes and preparing wonderful gifts. <3 Will publish blog post/speech soon.

I just sent an email to a group of 24 fancy schmancy people working on a fancy schmancy project, and got back 11 generic auto responders. This is not sustainable :(

@eikofried.bsky.socialOct 9, 2026, 1:05 PM

So many people now have generic auto-responders: I am too busy, please talk to this person for this, etc. I would love to do that, too. I get it. But you force me to delete an email every time I send you an email. If you think of this globally, that's a crazy amount of extra emails to manage.

New diamond open access outlet for developmental psych. Free to publish, free to read, and led by a great team. One more step away from for-profit publishers.

but they get so much information if you browse something in their environment .. all the info about your location, browser, the length of connection given the type of paper you're reading. this will help them so much with $$$ ...

Don't let journals host your supplementary. I've been putting them on the OSF for the last decade, and we now use Zenodo.
