Progressivity of the personal income tax schedule, including top marginal rates, bracket spread, and targeted credits (EITC-equivalents).
Taxation of capital income (dividends, capital gains, inheritance, wealth). Distinct from corporate rate.
Unconditional precommitment by the Fogh Rasmussen government (from the 2001 election campaign and first governing-statement) to freeze every direct and indirect tax rate in nominal terms, with the real-estate tax (ejendomsvaerdiskat) frozen in DKK. Any new or higher tax requires an offsetting reduction elsewhere. Maintained through successive V-K governments.
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.
