Pre-registration
Across Latin American economies 1990-2024, the cross-country variation in real-GDP growth is materially driven by the global commodity-price cycle, with a measurable "China-supercycle" dividend 2003-2014 and a "post-supercycle penalty" 2014-2019. The pre-registered claim is (a) panel-FE regression of real-GDP growth on a country-specific terms-of-trade index shows a positive coefficient at p < 0.05 across the panel, AND (b) the cumulative growth gap between commodity-export-heavy LATAM economies and manufacturing-heavy LATAM economies widened during 2003-2014 and narrowed (or reversed) during 2014-2019, AND (c) sovereign-debt spreads (proxied by external debt service share of exports) move inversely with terms of trade. The mechanism is the standard external-finance + tradables-channel transmission of commodity prices to growth.
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
Not supported if (a) terms-of-trade coefficient on real-GDP growth is not positive at p < 0.05 across the panel, OR (b) the cumulative growth gap between commodity-heavy and manufacturing-heavy sub-panels did not widen 2003-2014 and narrow 2014-2019, OR (c) external-debt-service share of exports does not move inversely with terms of trade.

The pre-registered claim is (a) panel-FE regression of real-GDP growth on a country-specific terms-of-trade index shows a positive coefficient at p < 0.05 across the panel, AND (b) the cumulative growth gap between commodity-export-heavy LATAM economies and manufacturing-heavy LATAM economies widened during 2003-2014 and narrowed (or reversed) during 2014-2019, AND (c) sovereign-debt spreads (proxied by external debt service share of exports) move inversely with terms of trade.

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