What the policy did

Following the February 2022 Russian invasion of Ukraine, Denmark held a referendum on 1 June 2022 on abolishing its 1993 EU-treaty defence opt-out; 66.9% voted 'Yes' and the opt-out was formally lifted, enabling Danish participation in CSDP operations and EDA. The referendum was accompanied by a multi-party 'National Compromise on Danish Security Policy' (6 March 2022) committing Denmark to raising defence spending to 2% of GDP by 2030 (later accelerated) and to additional military support for Ukraine. Part of the same policy arc was the diplomatic and forensic response to the 26 September 2022 sabotage of the Nord Stream pipelines in the Danish and Swedish EEZs.

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.

intended
spending level
fiscal.spending_level
General government spending as share of GDP, excluding transfers already captured under fiscal.transfer_expansion to avoid double-counting.
increased · moderate
higher spending share
Defence spending uplift to 2% of GDP.
energy supply security
regulatory.energy_supply_security
Policy posture toward energy supply security — domestic production capacity, import diversification, strategic reserves, nuclear stance, fossil-fuel mix discipline.
increased · moderate
higher supply-security posture (diversified, strategic reserves)
Post-Nord-Stream diversification, LNG and interconnector build-out, strategic-reserve posture.

Empirical evidence — linked hypotheses

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?".

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.

German industrial gross value added, manufacturing output, and real household income diverged materially from a synthetic-Germany donor- pool counterfactual over 2018-2025, and a variance decomposition across candidate channels attributes the majority of the divergence to regulatory-channel factors (Environmental Policy Stringency index increase post-2017, nuclear-phase-out schedule, single-supplier Russian gas dependency lock-in, industrial emission and reporting rules) rather than to fiscal-channel factors (general government consumption and tax burden were broadly stable across the Merkel late-term and Scholz years, with the debt brake in effect until 2023).
