Environmental regulation stringency — emissions caps, standards, phase-out mandates, carbon pricing, renewable portfolio standards.
Size of cash and near-cash transfer programmes (unemployment benefits, means-tested assistance, universal child benefits). Architecturally distinct from forced-saving schemes — see condition welfare_architecture.
Progressivity of the personal income tax schedule, including top marginal rates, bracket spread, and targeted credits (EITC-equivalents).
Austria's Ecosocial Tax Reform introduced a national CO2 price in sectors outside the EU ETS (transport, heating) at EUR 30/t from 1 October 2022, rising on a pre-announced schedule to EUR 35 (2023), EUR 45 (2024), EUR 55 (2025). Revenues are returned per-capita through the regionally-graduated Klimabonus (EUR 250-500 depending on public-transport accessibility of the recipient's municipality). Package also reduced the second and third income-tax brackets (30%->20% on the second bracket step-wise, 41%->40%, 48%->47%), raised the Familienbonus to EUR 2,000/child, and committed to a staged Koerperschaftsteuer cut 25%->24%->23%. Framed by OeVP and Greens as a textbook carbon-price-plus-dividend design delivering ecological and distributional goals simultaneously.
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.
