Corn Laws Repeal — UK 1846

GBR·1846 – 1849·enacted 1846-06-26·Conservative split — majority-opposition coalitioncandidate

What the policy did

PM Robert Peel (Conservative) split his party to repeal the tariffs on imported grain enacted 1815. Irish Potato Famine catalysed the reform. Phased tariff reduction through 1849. Marked the UK's transition to unilateral free trade — subsequent Cobden-Chevalier Treaty 1860 extended to European bilateral free trade. Historical landmark of classical-liberal trade policy: the Anti-Corn Law League (Cobden, Bright) argued free trade would lower food prices and expand manufacturing. Post-repeal, UK agricultural employment fell but real wages rose, industrial output accelerated. Canonical reference case for trade-openness direction.

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.

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.

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.

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.

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.
