What the policy did

Magnitude 7.8 + 7.5 earthquakes struck south-east Turkey 6 February 2023, killing over 50,000 and affecting 11 provinces. Three-month OHAL declared 8 Feb 2023; additional earthquake tax ("deprem vergisi") levied via Law 7440 (12 Mar 2023) including corporate one-off and special-consumption surcharges estimated to raise ~TRY 130bn.

Programme bridges the 2018-2023 and 2023-present movement phases and is co-executed post-election.

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.
