Environmental regulation stringency — emissions caps, standards, phase-out mandates, carbon pricing, renewable portfolio standards.
Statutory and effective corporate tax rates, treatment of depreciation, and international competitiveness.
Trade policy openness — tariffs, non-tariff barriers, FTAs, industrial protection.
Immigration policy openness — work visas, family reunification, asylum processing, border enforcement posture.
Repeal of the 2011 Clean Energy Act carbon-pricing mechanism enacted by the Abbott LNP government through the Clean Energy Legislation (Carbon Tax Repeal) Act 2014, ending the AUD 23/tCO2 fixed price scheduled to transition to an emissions-trading scheme. Replaced explicit carbon pricing with the discretionary Emissions Reduction Fund (Direct Action) reverse-auction subsidy programme. Marked the only repeal of a national carbon-pricing system to date.
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.
