What the policy did

Agreement ("Atomkonsens") of 14 June 2000 between the Schröder Red- Green government and German nuclear utilities to phase out nuclear power: per-reactor residual-electricity quotas allocated, no new- build, implicit end-of-life ~2022. Codified in the Atomgesetz amendment of 26 April 2002. (Merkel extended and then reversed course 2010-2011.)

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.

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?".

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).

Countries with aggressive green-transition regulatory stringency layered on top of gas-indexed wholesale electricity markets and premature phase-out of firm-dispatchable generation (Germany, UK, Belgium, Netherlands) have experienced materially higher industrial electricity prices 2015-2023 than comparable economies with more measured transition paths (France's nuclear retention, Nordic hydro, USA's shale-gas-backed grid).

Germany's industrial electricity prices diverged upward from a basket of comparable industrial peers (United States, France, Sweden, Norway, Finland) after the 2011 Energiewende pivot and the gap widened further through the 2014 nuclear-phase-out milestones and the 2022 gas crisis.

Germany's manufacturing value-added share of GDP declined from approximately 22-23% in 2017 to approximately 18-19% by 2024, a historically large shift for a mature economy over seven years.

EU Emissions Trading System (ETS) allowance prices traded in a sustained €70-100/tCO2 range from late 2021 through 2024 (with a peak at €105 in February 2023), a step-change above the €5-30 range that prevailed through Phase I-III (2005-2020).

Countries that legislated and executed nuclear phase-outs (Germany 2011-2023, Belgium 2003 law with 2025-2035 phase-out, Switzerland 2017 vote) experienced over 2010-2024 (a) higher industrial electricity prices, (b) higher wholesale electricity price volatility, and (c) greater reliance on fossil-fired back-up capacity for grid balancing, relative to nuclear-retaining peers (France, Finland post-2023 Olkiluoto 3, Sweden, USA).
