Rule of law as institutional substrate — contract enforcement, judicial independence, equal treatment before the law. Upstream of most other axes.
Security of private property rights — formal recognition, expropriation risk, titling systems.
The National Bureau of Statistics under Statistician-General Yemi Kale released on 6 April 2014 the rebased GDP series using 2010 as base year (replacing the 1990 base), recalculating Nigerian nominal GDP upward by approximately 89% to $509bn for 2013. Nigeria overtook South Africa as Africa's largest economy, revealed telecoms, entertainment (Nollywood), and services as dominant sectors. Triggered IMF/World Bank reclassification of Nigeria's debt ratios and tax-to-GDP ratios (latter fell to ~6%). Statistical — not a policy shift per se — but institutionally consequential for subsequent fiscal and monetary analysis.
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.
