Charlie McCreevy's first budget as Minister for Finance halved Ireland's capital-gains tax headline rate from 40% to 20% effective from December 1997, legislated in the Finance Act 1998. The cut was credited with sharply increasing realisations and CGT receipts during the late-1990s expansion and formed part of a broader low-rate, broad-base tax strategy that accompanied the Celtic Tiger growth phase.
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.
