What the policy did

National Health Insurance Act enacted 1999, effective 1 July 2000, merging 139 separate occupational and regional health- insurance societies into a single-payer National Health Insurance Corporation (NHIC). Self-employed and rural regional pools (Medical Insurance Management Corporation) had been structurally underfunded under earlier multi-pool regime; unification cross-subsidised rural/self-employed from urban wage-earner pools. Financial integration completed July 2003 after transition. By 2003 covered ~97% of population (remaining via Medical Aid for very poor). Replaced Bismarckian multi-pool architecture with British-style single-payer while retaining private-provider delivery.

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.

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?".

Cuban post-1991 Special Period forced degrowth (real GDP per capita contracted ~35% over 1989-1993 after the Soviet bloc collapse cut off concessional sugar/oil terms) demonstrated that basic-needs provision (life expectancy, infant mortality, primary-school enrolment) can be maintained — or improved — during rapid material-throughput reduction when institutions are aligned around free universal health and education.
