What the policy did

Decreto-legge 39/2024 (Law 67/2024) tightening Superbonus access and transfer mechanics, following earlier Decreto-legge 11/2023 that had already restricted cessione del credito / sconto in fattura for works started after February 2023. Key 2024 measures: blocked remontage of the cessione mechanism for residual cases; further tightened eligibility for heritage and condominio projects; capped forward fiscal cost through 2026; tightened anti-fraud controls on receivables purchased by banks (spread-recognition limits). Ex-post Corte dei Conti updates cumulative gross fiscal cost of Superbonus regime ~€220bn by 2024 against ex-ante ~€35bn — ~6x blow-out that materially moved Italy's deficit path. Construction-sector boom (GVA +40% cumulative 2020-2023) reversed sharply in 2024 as work pipelines exhausted. Policy analytically important as natural- experiment case of uncapped demand-side fiscal credit with market- liquid transfer instrument; influenced EU fiscal-governance discussions on contingent liabilities.

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.

Large welfare states sustain long-run real GDP per capita growth when paired with market flexibility (low product- and labour-market barriers), trade openness, and fiscal discipline (debt-to-GDP below 90%), but not when paired with rigid product and labour markets, in an OECD and rich- country panel 1980-2020.
