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,…

Maar voortgaande en versnellende klimaatverandering vindt u geen probleem?

Vergunningen verlenen door de rekenmethode aan te passen. We zijn beland in de Sovjet Unie van de jaren 80. En na al teveel politiek rekenen ontplofte #tsjernobyl. Ons milieubeleid is één grote kernramp geworden.

Waarom is die netcongestie ontstaan, denkt u?

@gerrithiemstra.bsky.socialOct 8, 2026, 7:19 PM

Dat is dan niet zo slim van de "onderkant"(uw woorden), want het is juist de rechtse elite die de laatste 15 jaar aan de macht is geweest en er voor heeft gekozen om deze problemen voor zich uit te schuiven en de asielzoekers de schuld te geven.

Dit is een goede ontwikkeling! Maar ik hoop dat u zich realiseert dat klimaatverandering ons nog heel veel geld gaat kosten.

Elke liter koolwaterstoffen (zoals diesel) die wordt verbrand, draagt bij aan klimaatverandering.

In 1992 Peter Ratcliffe received this rejection from Nature. Almost 30 years later he won the Nobel Prize for the same discovery.

Het punt is dat de regenhoeveelheden niet gelijkblijven, maar toenemen als gevolg van doorgaande en versnellende klimaatverandering.

France’s ongoing drought has once again pushed soil moisture further below historical levels than any previously recorded drought. Uncharted territory.

@gerrithiemstra.bsky.socialOct 2, 2026, 4:49 PM

Dat klopt, maar de regenhoeveelheden en de bijbehorende overlast is inmiddels structureel groter. Een belangrijke factor is de extreem warme Middellandse Zee. Dat bevordert de intensiteit van de buien.
