General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.
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.
Targeted industrial and sectoral subsidies (renewable energy, chip manufacturing, agriculture, green hydrogen, etc).
Direction of monetary-base expansion decisions relative to trend. Separate from fiscal.transfer_expansion even when correlated.
In response to the global financial crisis the Bank of Japan cut the uncollateralised overnight call rate from 0.5% to 0.1% in two steps (October and December 2008), expanded outright JGB purchases, and introduced complementary deposit facility, CP/corporate bond purchase and US-dollar funds-supplying operations. The actions stabilised yen money markets and supported bank balance sheets through the post-Lehman dislocation.
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.
