What the policy did

Supplementary Minimum Prices (SMPs) introduced 1978 guaranteed minimum floor prices to sheep and beef farmers above Producer Board export returns; deficiency payments covered gap. By 1984 SMPs contributed ~40% of average sheep-farmer income. Fiscal cost peaked near NZ$700m/year. Removed under Rogernomics 1984-85, producing the deepest farm-sector shock in OECD history.

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TFP stagnation 1970-1989, underwent a canonical institutional and economic collapse 1989-1998 as plan-enforcement was withdrawn without functioning market institutions in place.

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.

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).

Across a broad panel of developing and emerging-market economies 1980-2020, price controls and directed input subsidies predict higher capital misallocation — measured by the dispersion of the marginal product of capital across firms or sectors — and lower long-run total-factor-productivity growth.

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.

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.

Among high-income economies 2000-2020, startup density (new high- growth firms per 1000 working-age population) predicts frontier prosperity — measured by real GDP per capita growth and productivity growth — more strongly than industrial-policy spending as a share of GDP.

In a panel of middle-income countries 1990-2020, export complexity (Hausmann-Hidalgo Economic Complexity Index) rises more following reforms that improve foreign market access and reduce domestic entry barriers than following expansions of subsidy-only industrial policy.
