What the policy did

Nippon Telegraph and Telephone Public Corporation restructured into NTT Corporation under the NTT Corporation Act (enacted 25 Dec 1984, effective 1 Apr 1985). Initial 100% government shareholding reduced through public offerings Feb 1987, Nov 1987 and Oct 1988, raising ~JPY10tn — among the largest privatisations in history to that date. Paired with the Telecommunications Business Law 1 Apr 1985 opening the long-distance market to Type I and Type II carriers (DDI, Japan Telecom, Teleway Japan from 1987).

Policy-content fingerprint — what this policy moved, on which axes

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TFP stagnation 1970-1989, underwent a canonical institutional and economic collapse 1989-1998 as plan-enforcement was withdrawn without functioning market institutions in place.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

China's 1978 Deng-era reforms — Household Responsibility System in agriculture, Special Economic Zones, dual-track price liberalisation, Township and Village Enterprise reform, gradual opening to FDI and trade — produced a structural break in per-capita GDP growth rates.

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.
