What the policy did

Post-referendum-2016 withdrawal. UK formally left EU 31 January 2020; Transition Period ended 31 December 2020; TCA in force 1 January 2021. Created new trade friction with EU (customs checks, rules-of-origin certification, divergent regulatory surveillance) despite zero-tariff/zero-quota provision. Controlled end of free movement of labour. Empirical estimates (Bank of England, OBR, LSE CEP) find substantial goods-trade reduction and measurable GDP-per-capita shortfall vs counterfactual (~4-5% by 2024). Services trade less affected but financial-services single-market access curtailed. Canonical large-scale deliberate trade-closure case in developed economy.

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?".

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.

Canada’s long-run prosperity after the Canada–US Free Trade Agreement (1988) and NAFTA (1994) is more associated with market openness than with national industrial-policy initiatives.

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.

Developmentalist East Asian states (South Korea, Taiwan, Singapore, China) pursuing active industrial policy — export-discipline, selective credit, state-directed FDI screening, targeted sector promotion — achieved higher long-run real per-capita GDP growth over 1960-2019 than otherwise-comparable countries starting at similar income levels in 1960.

The ASEAN-China Free Trade Area (ACFTA), with the goods agreement effective 2010-01-01 for the original ASEAN-6, raised ASEAN-6 merchandise-export intensity over the 2010-2019 window relative to non-ASEAN comparator economies.

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.

The African Continental Free Trade Area (AfCFTA), with trading formally commencing 2021-01-01, has not yet produced a measurable acceleration in aggregate African trade-openness ratios over the 2021-2024 window relative to a synthetic-control donor pool of non-AfCFTA emerging-market regions, because of slow tariff- schedule ratification, COVID-19 trade disruption, and weak cross-border infrastructure.

China's WTO accession (2001-12-11) triggered a structural acceleration in Chinese merchandise-export intensity and manufacturing value-added relative to a synthetic-control donor pool of large emerging economies that did not accede to the WTO on the same date.
