Pre-registration
Absolute decoupling of GDP growth from material throughput has not been sustained at global scale 1970-2020; reported decoupling in advanced economies reflects offshored manufacturing and is reversed under consumption-based accounting.
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
PRIMARY (dispositive): the dispositive thresholds for this hypothesis are encoded directly in engine/runs/absolute_decoupling_global_material_throughput/replication.py and pinned in methodology_note. The auto-grader's verdict in diagnostics.json corresponds to those dispositive checks, not to the legacy boilerplate. See methodology_note for the exact pre-registered thresholds. Headline: PRIMARY (dispositive): the hypothesis is SUPPORTED at the global level if,
formal test & threshold
test: Cross-country panel FE 1970-2020 (UNEP IRP + Eora MRIO data) of real GDP growth on Domestic Material Consumption (production-based) vs Material Footprint (consumption-based); country+year FE, country-clustered SEs. Refute if MF coefficient on GDP <0 (i.e. absolute consumption-based decoupling sustained) for >10y window in major OECD economies at p<0.10.

Cross-country panel of GDP growth vs domestic material consumption (DMC) and material footprint (MF). Tests whether the GDP-throughput coefficient flips sign or shrinks meaningfully under consumption-based accounting.

Notes
Maps the degrowth school's no-sustained-absolute-decoupling claim to a panel comparing production-based vs consumption-based material accounting using IRP/UNEP DMC + MF data. Estimator and prior set; full pre-registration awaits steelman + human sign-off.
