OECD countries that deliver a larger share of low-income support through in-work benefits and earnings disregards, rather than through non-work-conditioned transfers, have higher employment rates among low-education adults and single parents without mechanically higher relative poverty. The directional claim is that stronger in-work benefit intensity predicts a positive low-income employment coefficient and a non-positive relative-poverty coefficient after controlling for total social spending, childcare spending, and macroeconomic conditions.
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
Refuted if in-work benefit intensity is non-positive for low-education and single-parent employment, or if the positive employment coefficient is accompanied by a positive and significant relative-poverty coefficient after controlling for total social spending. If in-work benefits merely relabel existing employment without raising employment, the claim is refuted.

Two-way FE model comparing in-work benefit intensity with non-work cash-transfer intensity while holding total social spending constant. Robustness checks estimate first differences around major EITC, Working Tax Credit, Prime d'activite, and similar reforms where local coding permits.

The directional claim is that stronger in-work benefit intensity predicts a positive low-income employment coefficient and a non-positive relative-poverty coefficient after controlling for total social spending, childcare spending, and macroeconomic conditions.
- Falsification rule: Refuted if in-work benefit intensity is non-positive for low-education and single-parent employment, or if the positive employment coefficient is accompanied by a positive and significant relative-poverty coefficient after controlling for total social spending. If in-work benefits merely relabel existing employment without raising employment, the claim is refuted.

Strongest opposing argument
Every hypothesis ships with its charitable opposing argument. The framework earns credibility by handling objections at their strongest, not weakest.
Notes
Candidate Worker C spec. It challenges redistribution claims that ignore work-conditioning design, while remaining open to the possibility that unconditional support performs equally well.
