Progressivity of the personal income tax schedule, including top marginal rates, bracket spread, and targeted credits (EITC-equivalents).
Statutory and effective corporate tax rates, treatment of depreciation, and international competitiveness.
General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.
Lower marginal tax rates, broaden tax base, simplify brackets, index to inflation. ERTA 1981 cut top marginal rate from 70% to 50%; TRA 1986 cut it further to 28% while eliminating many tax shelters. Deficit expanded as cuts were not matched by spending cuts; supply-side claim that cuts would pay for themselves through growth was partially but not fully borne out.
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.
