Taxation of capital income (dividends, capital gains, inheritance, wealth). Distinct from corporate rate.
Environmental regulation stringency — emissions caps, standards, phase-out mandates, carbon pricing, renewable portfolio standards.
Grunnrenteskatt on onshore wind power at 25% effective rate on economic rent above a production-volume allowance, stacked on top of the 22% ordinary corporate rate, mirroring the earlier salmon rent-tax design. Host municipalities continue to receive production-fee share. Rationale extends the resource-rent-capture principle (petroleum, hydropower, aquaculture) to windfall profits generated by Nord Pool price elevation on licensed wind generation. Retroactively applied from 2024 income year after parliamentary passage in December 2023.
Per invariant 3, reforms are scored by what they did on each channel-separated axis, not by the party that enacted them. This fingerprint is how the policy-match engine finds historical analogues.
Explicit links are curated by the author. Inferred links are hypotheses in the library that test the same axes this policy moved — the framework's answer to "what does the data say about a policy like this?".
Ranked by axis-fingerprint overlap with this policy. Direction match bolded — those are the closest historical analogues. Shape of the match is what drives policy-outcome comparison, not the country or party label.
