What the policy did

Angola created Sonangol as the national oil company while preserving offshore production arrangements with foreign operators to sustain petroleum revenues through civil war. Oil became a relatively insulated enclave that financed the MPLA state despite the broader command economy and conflict conditions.

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

↑

sectoral licensing

regulatory.sectoral_licensing

Sector-specific licensing regimes, concentration / quota allocation, state-controlled entry (energy, telecoms, healthcare, banking).

increased · strong

tighter sectoral licensing / more state gating

Oil exploration and production were routed through state concession authority and Sonangol.

↑

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 · strong

higher spending share

Petroleum rents financed wartime state spending and public enterprise commitments.

↑

trade openness

regulatory.trade_openness

Trade policy openness — tariffs, non-tariff barriers, FTAs, industrial protection.

increased · weak

more open trade

Foreign oil operators remained central to offshore production despite socialist controls elsewhere.

↑

energy supply security

regulatory.energy_supply_security

Policy posture toward energy supply security — domestic production capacity, import diversification, strategic reserves, nuclear stance, fossil-fuel mix discipline.

increased · moderate

higher supply-security posture (diversified, strategic reserves)

State command over petroleum strengthened sovereign control of the energy revenue base.

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?".

Estonia adopted among the most radical market-liberalisation packages of any post-Soviet state — flat tax (26% universal rate, 1994), currency board (EEK pegged to DM/EUR, 1992), rapid privatisation, unilateral free trade, and minimal capital controls — and by 2007 had recovered to Soviet-era GDP per capita levels and substantially exceeded them, while Belarusian and Ukrainian peers had not recovered comparably.

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.

Canada’s long-run prosperity after the Canada–US Free Trade Agreement (1988) and NAFTA (1994) is more associated with market openness than with national industrial-policy initiatives.

Singapore's long-run prosperity and frontier convergence are better predicted by extreme trade openness, strong rule of law, competitive product and services markets, and high economic freedom than by state ownership or industrial targeting alone.

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).

Developmentalist East Asian states (South Korea, Taiwan, Singapore, China) pursuing active industrial policy — export-discipline, selective credit, state-directed FDI screening, targeted sector promotion — achieved higher long-run real per-capita GDP growth over 1960-2019 than otherwise-comparable countries starting at similar income levels in 1960.

Major trade-liberalisation events — defined as sharp, policy-driven increases in trade-to-GDP openness sustained over at least 5 years — are associated with positive subsequent per-capita GDP growth over 10-year horizons, relative to matched non-liberalising controls.
