Pre-registration
Across countries 1996-2023, higher WGI Rule of Law (RL) scores predict higher subsequent real per-capita GDP growth, conditional on standard controls (initial income, investment share, trade openness, demographic composition). The relationship is consistent with the Acemoglu-Robinson institutional-growth hypothesis: property rights, contract enforcement, and impartial adjudication raise the expected return on productive investment and lower the cost of transactions, producing a compounding growth advantage that is not reducible to geography, culture, or initial income. The pre- registered claim is that within-country increases in RL over 5-year blocks positively predict next-block growth, and that cross- sectional rule-of-law level correlates positively with country-mean growth, with effect size consistent with the Kaufmann-Kraay 2002 and Acemoglu-Johnson-Robinson 2001 ranges.
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
Not supported if either (a) the two-way FE panel coefficient on WGI RL is not positive and significant at 5% on 5-year-forward per-capita GDP growth, OR (b) the cross-sectional country-mean coefficient is not positive at 5%, OR (c) the coefficient collapses by more than 70% when WGI Government Effectiveness is added as a co-regressor (suggesting WGI RL is identifying off a general institutional quality factor rather than rule of law specifically). Support requires at least 2 of 3 conditions to be met; 3 of 3 is strong support.
formal test & threshold
test: panel_plus_cross_section_plus_ge_robustness threshold: At least 2 of 3 conditions: panel_FE_beta(RL) > 0 at p<0.05 AND cross_section_beta(RL_mean) > 0 at p<0.05 AND RL_coefficient_attenuation_when_GE_added < 70%

Two-way FE panel with standard errors clustered by country. Primary identification from within-country variation in RL over 5-year blocks. Robustness: cross-sectional regression of country-mean growth 1996-2023 on country-mean RL, reported separately. IV robustness using Acemoglu-Johnson-Robinson 2001 settler-mortality instrument is noted as out of scope for v1 because the instrument's validity is contested (Albouy 2012) and the v1 spec sticks to panel-FE identification.

Strongest opposing argument
Every hypothesis ships with its charitable opposing argument. The framework earns credibility by handling objections at their strongest, not weakest.
Notes
This hypothesis deliberately restricts to the associational claim. The causal version (institutions cause growth rather than co-vary with it) requires stronger identification than WGI panel variation provides; the steelman addresses this and a v2 would use natural- experiment variation (colonial settler mortality, legal-origin heritage) to separate institutions-causes-growth from growth- causes-institutions.
