General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.
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).
Taxation of capital income (dividends, capital gains, inheritance, wealth). Distinct from corporate rate.
The Canada Child Benefit, introduced in Budget 2016 by the new Trudeau Liberal government, replaced the prior Universal Child Care Benefit and Canada Child Tax Benefit with a single income-tested monthly transfer paying up to C$6,400/year per child under 6 (lower for older children) and phasing out across upper income deciles. CRA delivers the benefit on a tax-free basis, and it is widely credited with material reductions in the LIM after-tax child-poverty rate by 2018.
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.
