Pre-registration
Mexico's 2019 phase-out of Prospera (formerly Oportunidades / Progresa, the canonical CCT programme studied since 1997) and replacement with un-conditional cash-transfer schemes under AMLO produced a measurable rise in extreme-poverty headcount and a deterioration in school-attendance among poor children of at least 3 percentage points within three years (2019-2022), identified off the synthetic-control gap with LatAm peers (BRA, COL, PER) maintaining CCT continuity.
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
Refuted if the synthetic-control gap on extreme-poverty headcount at 3-year horizon is below +3pp, OR if the school-attendance gap is above minus-3pp (i.e., attendance does not deteriorate), OR if placebo permutation p > 0.10 on either outcome.

Detailed result card
Result card - welfare_transfer_mexico_prospera_phaseout_2019
Verdict: REFUTED - poverty moved -1.6pp by 2022 and -2.3pp by 2024, opposite the registered +3pp rise
Exact Local Benchmark
- Extreme poverty was 3.9% in 2018 and 2.3% in 2022.
- By 2024 it was 1.6%, a -2.3 pp move from 2018.
- Gini moved -2.5 pp from 2018 to 2022.
Caveats
- The poverty leg is decisive against the registered direction; local secondary-attendance coverage ends before the phase-out.

Strongest opposing argument
Every hypothesis ships with its charitable opposing argument. The framework earns credibility by handling objections at their strongest, not weakest.
