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?".

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.

Singapore's long-run prosperity and frontier convergence are better predicted by extreme trade openness, strong rule of law, competitive product and services markets, and high economic freedom than by state ownership or industrial targeting alone.

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 countries 1990-2020, accession to a substantive free-trade agreement (FTA) — defined as a WTO-notified preferential-trade agreement going beyond MFN with measurable bilateral tariff reductions — is followed by higher trade openness and higher per-capita real GDP growth in the post-accession 5-year window than in the matched pre-accession 5-year window.

Under Financial Secretary John Cowperthwaite (1961–1971) and successors, Hong Kong pursued near-laissez-faire economic policy — no capital controls, no industrial policy, minimal tariffs, low flat taxes, and light labour regulation; between 1960 and 1997 Hong Kong's GDP per capita rose from approximately $4,000 to $26,000 (2011 PPP), converging almost fully to UK levels and surpassing most continental European economies.

Across a pre-registered panel of OECD and major emerging-market economies from 1996 to 2023, stronger rule-of-law institutions predict higher high-technology export intensity after country and year fixed effects and basic macro controls.

Across emerging-market and developing economies 1990-2020, stronger contract enforcement — measured by years to resolve a commercial dispute, contract-enforcement index, and legal-origin dummies — predicts whether foreign-direct-investment inflows produce productivity spillovers to domestic firms rather than enclave effects.
