Progressivity of the personal income tax schedule, including top marginal rates, bracket spread, and targeted credits (EITC-equivalents).
Ease of hiring/firing, collective-bargaining scope, minimum wage rigidity, temporary/permanent contract regulation.
Earned-income tax credit (EITC-analogue) introduced 1 Jan 2007 as the signature "arbetslinjen" (work-line) measure of the Reinfeldt Alliance. Expanded in four successive steps (2007, 2008, 2009, 2010) and made permanent, substantially increasing take-home pay from employment income relative to transfers. Raised labour-supply incentive for low-to-median earners.
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.
