Pre-registration
Fiscal multipliers are state-dependent: large at ZLB, small near full employment; no single-number answer is policy-relevant.
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
The hypothesis is falsified if the preregistered empirical test shows the opposite direction of the claim at conventional significance (p < 0.05), or if the primary outcome measure does not move in the claimed direction.

State-dependent local projections (Auerbach-Gorodnichenko / Ramey- Zubairy) on OECD panel 1971-2023 with regime indicator (ZLB or high-slack vs normal). Regime-conditional IRFs report multiplier state-dependence. Country and year FE; clustering by country.

Pre-registration
- Claim: Fiscal multipliers are state-dependent: large at ZLB, small near full employment; no single-number answer is policy-relevant.
- 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.

Notes
Stub seeded from an empirical-pragmatist school prediction about state-dependent fiscal multipliers (large at ZLB, small at full employment). Identification of slack regimes vs ZLB regimes is delicate; needs human review of regime-dating cutoffs.
