Direction of monetary-base expansion decisions relative to trend. Separate from fiscal.transfer_expansion even when correlated.
General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.
Ease of hiring/firing, collective-bargaining scope, minimum wage rigidity, temporary/permanent contract regulation.
Trade policy openness — tariffs, non-tariff barriers, FTAs, industrial protection.
Three-arrow programme launched under Shinzō Abe + BoJ Governor Haruhiko Kuroda: (1) aggressive monetary expansion via QQE (Quantitative and Qualitative Easing, 2013; YCC added 2016), (2) flexible fiscal policy with supplementary budgets, (3) structural reforms including TPP-joining, corporate governance reform (JPX400, stewardship code), some labour-market liberalisation, and womenomics. Ended deflation (CPI positive from 2013), supported JPY depreciation, and raised equity valuations — but structural-reform third arrow was partial. 2014 consumption-tax hike arguably premature and temporarily reversed the fiscal arrow. Extended under Kishida post-Abe.
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.
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?".
Ranked by axis-fingerprint overlap with this policy. Direction match bolded — those are the closest historical analogues. Shape of the match is what drives policy-outcome comparison, not the country or party label.
