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. www.nber.org/papers/w35854

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,…

New preprint! A review article on Generative AI and Society, with the fantastic @thomasdavidson.bsky.social & Danny Karell (smartly not online!) osf.io/preprints/so... The lit on genAI is sprawling and mostly not in sociology. Our goal is to synthesize core themes relevant to sociologists. +

GENERATIVE AI AND SOCIETY
Laura K. Nelson,
Daniel Karell,
and Thomas Davidson

ABSTRACT
For sociologists, generative AI inherits the legacy of earlier computational technologies: it is an advancement of machine learning already adopted as a methodology, and it intervenes in a society already shaped by algorithmic systems. Yet it also has a dimension that distinguishes it from previous computational methods, and one that makes it inherently sociological: its interactivity. In this review, we conceptualize the interactivity of generative AI and introduce a framework for understanding how it operates across individual, organizational, and institutional life. Specifically, the framework specifies how generative AI expands users, functions as a proxy for society, and expresses power,
both in sociological practice and in society. We conclude by suggesting three dynamics driven by generative AI that sociology will face in the near future: the transformation of scientific practice, the reorganization of social interaction, and the acceleration of algorithmic governance.

Keywords: generative AI, interaction, computational sociology, methods, algorithms, algorithmic governance

In nutrition research, the effect you estimate from a model is determined by which other dietary variables you adjust for. If you adjust for total energy intake, the effect will switch from an addition to a substitution. Which substitution will be determined by which other variables are adjusted.

What effect sizes can a design reliably detect, and how does that compare to the smallest effect size of interest? These questions are rarely pondered outside of experiments. I (with assistance from Claude) wrote an R package, "simpower", that helps with this: github.com/faranordk/si....

maddening. researchers shouldn't abide such policies not to disclose massive errors. pubpeer first, then the journal gets a chance to do the right thing.

The original claim that science was becoming less disruptive has appeared in more than 300 news stories worldwide.

The Belgian researchers submitted their critique to Nature in October 2023. It took the journal 32 months to accept it. While the critique was under review, Nature still published an editorial and ran a News Feature drawing on the original conclusion. During those years, the original paper was cited more than 1,000 additional times and used in at least 16 policy documents.

"Whereas the software bug was fixed by the open-source community in months, it took years for the scientific correction to be published," says Ginis. "And all this time, the journal's policies prohibited us from speaking to the press while our critique was under submission."

Other researchers in the field have suggested restricting the analysis to papers with at least 10 references and citations. When they follow this guideline, the Belgian team finds a slight, statistically significant increase in disruption. Still, this is not their conclusion.

Nice piece from the FT on issues with the measure of healthy life expectancy (HLE). The recent decline in HLE at birth in the UK is particularly driven by lower self-reported mental health of young people. While certainly a concerning development, this isn't a concern for pension policy.

Nice clear presentation of commonplace meta-analysis failure mode: Pooling coefficients that mean different things, because original models had different adjustment sets. A coefficient gets its meaning from the whole model, not just from the predictor variable it multiplies.
