What the policy did

Economic Stabilization (Temporary Provisions) Act April 1982 imposed import licensing, raised tariffs, restricted foreign-exchange allocations, tightened expatriate quota controls, and reduced compulsory saving. Defensive response to oil-price collapse and current-account crisis under Shagari NPN government. Did not adjust the fixed exchange rate or core subsidy regime — preserved the imbalances that produced the 1983 coup.

Empirical evidence — linked hypotheses

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.

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.
