What the policy did

The Law for Usury (Riba)-Free Banking 1983 converted Iran's banking system to Islamic-finance principles, prohibiting interest-based lending and requiring banks to operate via profit-sharing (mudaraba), partnership (musharaka), instalment-sale, and rental contracts. The Central Bank of Iran retained authority to set "expected profit rates" that effectively functioned as administered interest rates, reshaping credit allocation across the post-revolutionary 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.

intended

↓

product market competition

regulatory.product_market_competition

Product-market regulation, entry barriers, licensing burdens, network-industry regulation, price controls.

decreased · weak

more restrictive regulation, higher entry barriers

Mandatory contractual templates limited financial-product differentiation across banks.

↑

transfer expansion

fiscal.transfer_expansion

Size of cash and near-cash transfer programmes (unemployment benefits, means-tested assistance, universal child benefits). Architecturally distinct from forced-saving schemes — see condition welfare_architecture.

increased · weak

larger transfer footprint

Sub-market mandated profit rates on certain loans operated as implicit subsidies to favoured borrowers.

↓

trade openness

regulatory.trade_openness

Trade policy openness — tariffs, non-tariff barriers, FTAs, industrial protection.

decreased · weak

more protectionist

Foreign-bank participation became practically impossible under sharia-compliance and licensing rules.

↓

property rights

institutional.property_rights

Security of private property rights — formal recognition, expropriation risk, titling systems.

decreased · weak

weaker property rights

Profit-rate ceilings periodically imposed losses on depositors and creditors during inflation surges.

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.

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).

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.

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").

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.

Australia’s long expansion after the Hawke-Keating reforms (1983–1996) — including tariff cuts, financial deregulation, competition-policy introduction, and fiscal consolidation — is better predicted by market liberalisation than by sector-specific state direction.

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.
