What the policy did

Public offering of British Gas Corporation under Gas Act 1986 with 'Tell Sid' mass-marketing campaign. Raised £5.6bn; 4.5 million retail investors participated. Created Ofgas regulator; transferred the combined transmission, distribution, and supply monopoly intact (subsequently restructured in the 1990s). Largest privatisation to date at the time.

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TFP stagnation 1970-1989, underwent a canonical institutional and economic collapse 1989-1998 as plan-enforcement was withdrawn without functioning market institutions in place.

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.

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.

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).

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").

Among high-income and near-frontier economies from 1970 to 2024, lower product-market regulation, stronger competition, and stronger property rights predict higher long-run TFP growth than state ownership or targeted industrial-policy intensity.

Peru's 1990-1995 Fujimori shock-therapy package (price liberalisation, fiscal stabilisation under the August 1990 "Fujishock", Brady-style external debt restructuring 1996-1997, large-scale privatisation of SOEs, central-bank independence under the 1993 constitution, and trade liberalisation) produced a structural break in inflation and real-GDP per capita relative to Peru's 1985-1990 hyperinflation trajectory and relative to a Latin American peer pool that did not adopt comparable packages on the same timeline.
