Pre-registration
In OECD countries from 1990 to 2023, transfer-heavy welfare states predict lower prime-age labour-force participation when transfer expansion is not accompanied by strong work incentives, after controlling for income level, female education, ageing, unemployment, and macro shocks. The mechanism tested is the substitution and participation margin: redistribution can reduce durable poverty if it protects work attachment, but should weaken it when benefit design makes non-work relatively more attractive.
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
Supported if social_spending_share is negative at p <= 0.10 at below-median work_incentive_proxy and the interaction with work_incentive_proxy is positive. Refuted if social_spending_share is positive at below-median work incentives, or if the interaction is negative at p <= 0.10. Otherwise partial.

Primary specification includes social_spending_share, work_incentive_proxy, and their interaction. The mechanism is supported only if social spending has a more negative marginal association with participation when work incentives are weak.

- Claim: In OECD countries from 1990 to 2023, transfer-heavy welfare states predict lower prime-age labour-force participation when transfer expansion is not accompanied by strong work incentives, after controlling for income level, female education, ageing, unemployment, and macro shocks. The mechanism tested is the substitution and participation margin: redistribution can reduce durable poverty if it protects work attachment, but should weaken it when benefit design makes non-work relatively more attractive.
- Falsification rule: Supported if social_spending_share is negative at p <= 0.10 at below-median work_incentive_proxy and the interaction with work_incentive_proxy is positive. Refuted if social_spending_share is positive at below-median work incentives, or if the interaction is negative at p <= 0.10. Otherwise partial.

Strongest opposing argument
Every hypothesis ships with its charitable opposing argument. The framework earns credibility by handling objections at their strongest, not weakest.
Notes
Intended as a mechanism test for redistribution-heavy poverty claims: the key question is whether transfer design preserves labour-market attachment, not whether transfers reduce measured poverty in the same year.
