What the policy did

Agreement signed 22 Sep 1985 at the Plaza Hotel New York by G5 finance ministers (Japan, US, West Germany, France, UK) to engineer coordinated USD depreciation against yen and DM. USD/JPY moved from ¥240 (Sep 1985) to ¥150 (end-1987) — ~40% yen appreciation. BoJ easing to offset yen-shock (discount rate cut from 5% to 2.5% by Feb 1987) fed the 1986-1990 asset bubble.

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.

Across the 2008-2014 ZLB era and the 2020-2021 pandemic-response window, large-scale de-facto monetary finance of fiscal expansion in the US, Japan, and the Eurozone did not produce headline-CPI inflation consistent with naive quantity-theoretic monetisation predictions: cumulative central-bank balance-sheet expansion exceeded 15% of GDP while CPI YoY remained below 3% in each economy across both windows.

In a panel of advanced economies 1987-2007, base-money expansion and broad money growth correlate positively with asset-price indices (equity, real estate) but only weakly with headline CPI inflation.

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.

New Zealand’s 1984–1993 liberalisation (deregulation, tariff cuts, privatisation, inflation targeting, and fiscal consolidation) improved long-run macroeconomic stability and tradables-sector productivity over 1984–2024 relative to a synthetic counterfactual of OECD small open economies, but aggregate economy-wide labour productivity and TFP did not improve enough to support strong market-optimism claims.

Post-2008 large-scale asset purchase programmes by the Federal Reserve, ECB, Bank of England, and Bank of Japan produced a measurable divergence between asset-price inflation (equities and residential real estate) and headline consumer-price inflation until roughly 2021.
