What the policy did

The Loi sur la sortie progressive de l'énergie nucléaire à des fins de production industrielle d'électricité (31 January 2003), adopted under the Verhofstadt I purple coalition with Ecolo/Groen participation, prohibited new nuclear-plant construction and limited operating life of existing reactors to 40 years. The seven Doel and Tihange units were scheduled for closure between 2015 and 2025, subsequently amended through extension laws as supply-security concerns rose.

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).
decreased · weak
less progressive (flatter rates, compression, smaller credits)
Higher consumer electricity costs from phase-out functioned as a regressive implicit tax.
tax corporate
fiscal.tax_corporate
Statutory and effective corporate tax rates, treatment of depreciation, and international competitiveness.
decreased · weak
lower corporate tax burden
Decommissioning-fund accounting requirements added quasi-tax obligations on plant operators.
spending level
fiscal.spending_level
General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.
decreased · weak
lower spending share
Limited direct fiscal impact at enactment; required state spending rose only with later extensions.
immigration openness
regulatory.immigration_openness
Immigration policy openness — work visas, family reunification, asylum processing, border enforcement posture.
increased · weak
more open (easier legal immigration, broader asylum)
Coalition-package linkage; nuclear law itself moved energy regime, not migration.

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?".

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.
