Haiti's 2010-2024 governance trajectory — the failed post-earthquake reconstruction (2010-2015), Martelly-era PetroCaribe-fund mismanagement (2011-2016), Moïse assassination (July 2021), gang takeover of Port- au-Prince (2022-2024), and effective state collapse — produced a catastrophic economic collapse measurable in real-GDP-per-capita decline, life-expectancy stagnation, and emigration acceleration. The pre-registered claim is (a) cumulative log GDP per capita 2010-2024 (HTI) is negative (an absolute decline), AND (b) the WGI Government Effectiveness score declined by at least 0.5 standard deviations 2010-2023, AND (c) emigration stock as a share of population rose by at least 5 percentage points across the window. The mechanism is that state-capacity collapse compounds: each year of weak governance raises the cost of the next year's recovery, producing a self-reinforcing decline.
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
Not supported if (a) cumulative log_gdp_pc 2010-2024 (HTI) is not negative, OR (b) WGI Government Effectiveness change 2010-2023 is greater than -0.5 standard deviations, OR (c) emigration stock share rose by less than 5 percentage points.

- Claim: Haiti's 2010-2024 governance trajectory — the failed post-earthquake reconstruction (2010-2015), Martelly-era PetroCaribe-fund mismanagement (2011-2016), Moïse assassination (July 2021), gang takeover of Port- au-Prince (2022-2024), and effective state collapse — produced a catastrophic economic collapse measurable in real-GDP-per-capita decline, life-expectancy stagnation, and emigration acceleration. The pre-registered claim is (a) cumulative log GDP per capita 2010-2024 (HTI) is negative (an absolute decline), AND (b) the WGI Government Effectiveness score declined by at least 0.5 standard deviations 2010-2023, AND (c) emigration stock as a share of population rose by at least 5 percentage points across the window. The mechanism is that state-capacity collapse compounds: each year of weak governance raises the cost of the next year's recovery, producing a self-reinforcing decline.
- Falsification rule: Not supported if (a) cumulative log_gdp_pc 2010-2024 (HTI) is not negative, OR (b) WGI Government Effectiveness change 2010-2023 is greater than -0.5 standard deviations, OR (c) emigration stock share rose by less than 5 percentage points.

Strongest opposing argument
Every hypothesis ships with its charitable opposing argument. The framework earns credibility by handling objections at their strongest, not weakest.
Notes
Tests state-capacity collapse as the binding constraint on development outcomes.
