Sector-specific licensing regimes, concentration / quota allocation, state-controlled entry (energy, telecoms, healthcare, banking).
Targeted industrial and sectoral subsidies (renewable energy, chip manufacturing, agriculture, green hydrogen, etc).
Trade policy openness — tariffs, non-tariff barriers, FTAs, industrial protection.
General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.
France's post-Liberation provisional government nationalised core sectors of the economy in 1945–1946, including coal mines (loi du 17 mai 1946), electricity and gas (loi du 8 avril 1946 creating EDF and GDF), the Banque de France and four major deposit banks, Renault, and Air France. The wave brought roughly a fifth of the productive economy under state ownership and provided the institutional substrate for subsequent indicative planning and credit allocation.
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.
