What the policy did

Hipkins government rebranded and restructured the Ardern-era Three Waters programme as the Affordable Water Reforms, expanding the number of regional water services entities from four to ten and adjusting the vesting timeline, while retaining statutory Maori co-governance. Repealed by the incoming Luxon coalition in December 2023.

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?".

The Soviet central-planning system, having already exhibited TFP stagnation 1970-1989, underwent a canonical institutional and economic collapse 1989-1998 as plan-enforcement was withdrawn without functioning market institutions in place.

Across a broad panel of economies 1980-2020, market reforms (privatisation, trade liberalisation, and price decontrol) produce durable gains in real GDP per capita growth only when rule-of-law scores exceed a minimum threshold (WGI Rule of Law > -0.5, approximately the 40th percentile of the global distribution).

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.

Among high-income economies 1990-2020, services-sector competition — measured by low barriers to entry, low incumbent-protection scores, and high churn in retail, transport, communications, and professional services — predicts long-run prosperity (real GDP per capita growth and labour-productivity growth) better than manufacturing-specific industrial policy spending.

Rapid market liberalisation (price decontrol, mass privatisation, trade opening) under weak institutions produces large short-run welfare losses—rising mortality, falling life expectancy, rising inequality, and collapsing output—that may persist for at least a decade, compared to gradual reformers or non-reformers at similar initial income levels.

Following the 1989-1992 collapse of the Soviet bloc, post-communist countries that adopted market reforms rapidly (Poland, Estonia, Czech Republic, Hungary, Slovenia, Slovakia, Latvia, Lithuania — the "fast reformers") experienced faster recovery in life expectancy at birth than countries that reformed slowly or retained state-socialist economic structures (Russia, Ukraine, Belarus, Moldova, Kazakhstan — the "slow reformers").

Market-oriented reform episodes that persist for at least twenty years produce more durable GDP-per-capita and productivity gains than short reform bursts or state-led industrial-policy episodes without sustained market competition.

Starting from comparable 1945 post-war conditions — same ethnicity, language, pre-war German institutional and industrial inheritance, and with the GDR inheriting a larger share of pre-war industrial capital in Saxony and Thuringia — the Federal Republic's Soziale Marktwirtschaft (Ordoliberal market economy with welfare state) versus the German Democratic Republic's planned economy with administered prices, state-enterprise production, and soft budget constraints produced by 1989 a canonical divergence that pattern-matches >=7 of 10 pre-registered extreme-outcome metrics, each drawn from a different publisher or methodology family.
