Windfall tax on privatised utilities

GBR·1997 – ·enacted 1997-07-02candidate

What the policy did

One-off 23% tax on the difference between privatisation value and market value of privatised utilities (water, electricity, BT, BAA, Railtrack). Raised approximately £5.2bn. Proceeds earmarked for the New Deal welfare-to-work programme. Legally a one-off charge not a permanent tax; designed to recoup value from Thatcher-era privatisations seen as under-priced.

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.

Italy's Reddito di Cittadinanza (RdC, March 2019) reduced absolute-poverty headcount among low-income Italian households by at least 15% within three years (2019-2022) but produced no measurable improvement in employment-rate among working-age beneficiaries, identified off the synthetic-control gap with EU peers (ESP, GRC, PRT) lacking comparable means-tested guaranteed-minimum-income programmes pre-2020.

Japan's three consumption-tax hikes (1997 3->5, 2014 5->8, 2019 8->10 percent) raised the disposable-income Gini coefficient by at least 0.3 Gini-points cumulatively relative to G7-ex-JPN comparator synthetic control, with the regressivity bite partially offset by simultaneous tax-rebate / cash-transfer programmes.

The American Rescue Plan Act (March 2021) expansion of the Child Tax Credit to USD 3000-3600 per child with full refundability and monthly disbursement (July-December 2021) produced a measurable and immediate decline in monthly child-poverty rate of at least 4 percentage points (Center on Poverty and Social Policy at Columbia time-series), with the credit's December 2021 expiration producing a corresponding immediate reversal — providing high-frequency event-window evidence on near-instantaneous cash-transfer-to-poverty mechanics.
