What the policy did

Forsraspakken 2.0 ("Spring Package 2.0") reduced the top marginal PIT rate from 63% to 56% by abolishing the 6% middle-bracket tax, raised the top-bracket threshold, and broadened the base (pension-contribution cap reductions and limits on deductibility of interest on mortgage debt, phased 2012-2019). Partially financed by green-tax shifts.

Policy-content fingerprint — what this policy moved, on which axes

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.

Empirical evidence — linked hypotheses

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?".

German industrial gross value added, manufacturing output, and real household income diverged materially from a synthetic-Germany donor- pool counterfactual over 2018-2025, and a variance decomposition across candidate channels attributes the majority of the divergence to regulatory-channel factors (Environmental Policy Stringency index increase post-2017, nuclear-phase-out schedule, single-supplier Russian gas dependency lock-in, industrial emission and reporting rules) rather than to fiscal-channel factors (general government consumption and tax burden were broadly stable across the Merkel late-term and Scholz years, with the debt brake in effect until 2023).

In the cross-country panel of advanced economies post-1980, the top-1 percent share of total pre-tax national income exhibits a structural break upward in countries that adopted the Anglo-American liberalisation package (US, UK, Canada, Australia, New Zealand) and a flat-or-mildly- rising trajectory in coordinated-market economies (Germany, France, Sweden, Denmark, Netherlands), even though both groups experienced comparable real GDP per capita growth.

Chilean post-Pinochet tax progressivity reforms — Concertación-era Aylwin-Frei marginal-rate increases 1990-1995, Bachelet 2014 reform raising corporate rate from 20 to 27 percent + DTA tightening, Boric 2022-2024 reform attempts — produced gradual reductions in the Chilean top-1 pretax income share by at least 1.5 percentage points over 1990-2024 vs Latin-American synthetic comparator pool, with most of the level shift concentrated in 1990-2000 rather than the recent reform attempts.

Greek Memorandum-era tax hikes 2010-2018 (top marginal income rate raised to 45 percent, VAT hikes to 24 percent standard, ENFIA recurring property tax 2014, solidarity surcharge 2011-2019) raised the disposable-income Gini coefficient by at least 1.5 Gini-points relative to Eurozone- comparator synthetic control over the period, with the regressivity driven by VAT and property-tax incidence rather than income-tax progressivity.

Post-apartheid South African tax structure (top marginal income rate raised to 45 percent in 2017, capital-gains inclusion ratio raised 2012 + 2016, recurring property-tax effective burden via municipal rates) produced a measurable reduction in the South African top-1 pretax income share over 1995-2024 vs SADC synthetic comparator pool, with the recurring property-tax channel contributing more than the marginal-income-rate channel to the distributional effect.

Indigenous-managed parcels in the Amazon basin (BRA, PER, COL, ECU, BOL), Canadian First-Nations comanagement areas, and Australian Indigenous Protected Areas retain at least 20% more above-ground biomass per hectare than biome-matched state- protected and private parcels over 2003-2023, after controlling for slope, accessibility, and pre-treatment biome composition.

Progressive income-tax marginal rates (up to roughly 70% top rate) have been compatible with strong growth in post-war US 1945-1980 and Nordics, falsifying extreme-Laffer-curve positions.

Countries in the top quartile of Heritage lower-tax-burden score in 2024 have lower latest-available extreme-poverty headcount than bottom-quartile countries, consistent with free-market country policy regimes outperforming less market-oriented regimes on this outcome.
