General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.
Trade policy openness — tariffs, non-tariff barriers, FTAs, industrial protection.
Gierek-era doctrine of debt-financed rapid industrial modernisation via Western credits and turnkey plant imports (FSO Polonez Fiat- licensed car, Katowice steel mill, shipyards, petrochemicals). External debt grew from ~$1bn (1970) to ~$25bn (1980), making Poland the most indebted COMECON member. Investment share of GDP peaked ~35% in 1975 but export-revenue growth fell far short of debt-service obligations after 1979 Volcker real-rate shock.
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.
