Pre-registration
Post-1945 US and Western European public investment in rail/transit produced lower per-capita emissions than the post-1980 privatised-deregulated transport regime.
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
The hypothesis is considered falsified if the pre-registered empirical test shows the opposite direction of the claim at conventional significance (p > 0.10), or if the primary outcome measure moves less than 10% in the claimed direction across the sample. Exact thresholds will be pinned in the variables and estimator blocks when this stub is promoted from draft.
formal test & threshold
test: Pre/post-1980 comparison of transport-sector CO2 per capita (IEA, IRENA) for USA, GBR, FRA, DEU 1945-2020 conditional on transport-mode-share controls; country-clustered SEs, country+year FE. Refute if pre-1980 public-investment regime not associated with at least 15% lower transport CO2 per capita than post-1980 regime once oil-price/fuel-cost effects netted out at p<0.10.

Cross-country panel-FE comparing pre/post-1980 transport CO2 per capita with post-1980 privatisation indicator as treatment, controlling for oil price, population density, and GDP per capita. Country and year FE. Caveat: regime indicator is coarse — postwar US emissions trajectory dominated by interstate-highway buildout and suburbanisation, not "public investment" per se; identification is weak by design.

Pre-registration
- Claim: Post-1945 US and Western European public investment in rail/transit produced lower per-capita emissions than the post-1980 privatised-deregulated transport regime.
- Falsification rule: The hypothesis is considered falsified if the pre-registered empirical test shows the opposite direction of the claim at conventional significance (p > 0.10), or if the primary outcome measure moves less than 10% in the claimed direction across the sample. Exact thresholds will be pinned in the variables and estimator blocks when this stub is promoted from draft.
- Falsification test: Pre/post-1980 comparison of transport-sector CO2 per capita (IEA, IRENA) for USA, GBR, FRA, DEU 1945-2020 conditional on transport-mode-share controls; country-clustered SEs, country+year FE. Refute if pre-1980 public-investment regime not associated with at least 15% lower transport CO2 per capita than post-1980 regime once oil-price/fuel-cost effects netted out at p<0.10.
Estimate

Notes
Maps the eco-socialist school's postwar-public-transit-vs-privatised claim to a long-run pre/post comparison of transport-sector emissions per capita across USA and Western Europe. Estimator and prior set; full pre-registration awaits steelman + human sign-off.
