What the policy did

Montenegro AD government's headline fiscal content in the 2025 State Budget (Lei 45/2024, approved by Assembleia da República on 29 November 2024 with PS abstention). Expanded the IRS Jovem youth income-tax relief introduced by Costa's OE2024: full exemption in the first year of labour income after eligibility, followed by a progressively tapering relief (75% → 50% → 25%) across years 2-10, with eligibility extended up to age 35. Intended to address youth emigration and housing-affordability pressure. Combined with middle-bracket IRS rate reductions in the main schedule. Budget-cost estimate ~€645m on 2025 basis; revenue offsets limited to growth-feedback assumptions.

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.

intended
tax progressivity
fiscal.tax_progressivity
Progressivity of the personal income tax schedule, including top marginal rates, bracket spread, and targeted credits (EITC-equivalents).
increased · weak
more progressive (higher top rates, wider spread, larger targeted credits)
Age-targeted exemption adds progressivity at the bottom of the earnings distribution for the under-35 cohort; middle-bracket rate cuts partially offset by flattening the mid-schedule.
unintended / side-effect
spending level
fiscal.spending_level
General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.
increased · weak · unintended
higher spending share
Revenue-forgone relief treated as tax expenditure in Portuguese fiscal accounting; increases structural revenue loss ~0.2% GDP.

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?".

Large welfare states sustain long-run real GDP per capita growth when paired with market flexibility (low product- and labour-market barriers), trade openness, and fiscal discipline (debt-to-GDP below 90%), but not when paired with rigid product and labour markets, in an OECD and rich- country panel 1980-2020.
