Pre-registration
Chile’s long-run income convergence is stronger after the combination of market reforms (1975–1990) and democratic institutional repair (1990 onward) than under the earlier state-led import-substitution regime (1950–1973). In a synthetic-control design with Latin American comparators, Chile’s cumulative log GDP-per-capita growth from 1990–2024 exceeds the synthetic counterfactual built from pre-reform peers, and the post-1990 democratic period shows continued convergence relative to a counterfactual that stops at 1990.
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
Refuted if Chile’s cumulative log GDP-pc growth gap versus synthetic counterfactual over 1990-2024 is not positive and significant at p<0.10, or if the panel-FE coefficient on CHL × post-1990 is negative and significant at p<0.05.
formal test & threshold
test: synthetic_control_chile_convergence threshold: cumulative_log_gdp_pc_gap_1990_2024 > 0 AND p < 0.10; panel_fe_coef > 0 AND p < 0.10.

Pre-registration
- Claim: Chile’s long-run income convergence is stronger after the combination of market reforms (1975–1990) and democratic institutional repair (1990 onward) than under the earlier state-led import-substitution regime (1950–1973). In a synthetic-control design with Latin American comparators, Chile’s cumulative log GDP-per-capita growth from 1990–2024 exceeds the synthetic counterfactual built from pre-reform peers, and the post-1990 democratic period shows continued convergence relative to a counterfactual that stops at 1990.
- Falsification rule: Refuted if Chile’s cumulative log GDP-pc growth gap versus synthetic counterfactual over 1990-2024 is not positive and significant at p<0.10, or if the panel-FE coefficient on CHL × post-1990 is negative and significant at p<0.05.

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