Pre-registration
Jamaica's 2010-2024 fiscal-consolidation programme (under successive IMF SBA, EFF, and PLL programmes; combined with two domestic-debt restructurings — JDX 2010 and NDX 2013) succeeded in reducing public debt as a share of GDP from above 140% (2012) to below 75% (2024) while sustaining positive cumulative real-GDP growth and avoiding hyperinflation. The pre-registered claim is (a) gross general- government debt share of GDP fell by at least 50 percentage points 2012-2024, AND (b) cumulative log GDP per capita 2013-2019 (post-JDX/NDX, pre-COVID) is positive, AND (c) cpi inflation remained below 10% mean annualised across 2013-2019. The mechanism is a multi-cycle bondholder restructuring combined with primary- surplus discipline (>7% of GDP for several years), supported by an IMF-anchored political consensus. This is the canonical Caribbean case of orthodox debt sustainability.
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
Not supported if (a) gross_general_govt_debt_share_gdp(JAM, 2024) is not at least 50 percentage points below the 2012 peak, OR (b) cumulative log_gdp_pc 2013-2019 (JAM) is negative, OR (c) mean cpi_inflation_yoy(JAM, 2013-2019) > 10.

- Claim: Jamaica's 2010-2024 fiscal-consolidation programme (under successive IMF SBA, EFF, and PLL programmes; combined with two domestic-debt restructurings — JDX 2010 and NDX 2013) succeeded in reducing public debt as a share of GDP from above 140% (2012) to below 75% (2024) while sustaining positive cumulative real-GDP growth and avoiding hyperinflation. The pre-registered claim is (a) gross general- government debt share of GDP fell by at least 50 percentage points 2012-2024, AND (b) cumulative log GDP per capita 2013-2019 (post-JDX/NDX, pre-COVID) is positive, AND (c) cpi inflation remained below 10% mean annualised across 2013-2019. The mechanism is a multi-cycle bondholder restructuring combined with primary- surplus discipline (>7% of GDP for several years), supported by an IMF-anchored political consensus. This is the canonical Caribbean case of orthodox debt sustainability.

Strongest opposing argument
Every hypothesis ships with its charitable opposing argument. The framework earns credibility by handling objections at their strongest, not weakest.
Notes
Single-country descriptive spec; Jamaica's debt-restructuring trajectory is dispositive on its own.
