Progressivity of the personal income tax schedule, including top marginal rates, bracket spread, and targeted credits (EITC-equivalents).
Vázquez-II tax adjustment lifting top personal income tax (IRPF) marginal brackets, raising IASS pension tax on higher-bracket retirees, and trimming some corporate deductions, to close a widening fiscal deficit as commodity prices softened. Framed as targeted progressivity-raising rather than broad tax increase.
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.
