A 140-country panel dataset used to test the Wei-Zhang competitive-savings mechanism in a global context. The replication package by Brian Peters (2026) uses UN World Population Prospects 0-4 cohort sex ratio data and contains 5,455 observations. Key findings include a statistically significant positive coefficient for the sex ratio at birth on current-account balances.
Use Cases
- Replicate the regression analysis of current-account balances based on exogenous sex ratio proxies.
- Test the generalizability of the competitive-savings mechanism across different geographic regions.
- Analyze the relationship between predetermined birth cohort data and anticipatory saving behavior.
- Investigate the orthogonality of sex composition to age structure and income conditioning variables.
Strengths
- Dataset includes 5,455 observations for the main regression model.
- Key coefficient for sex ratio at birth is reported as +43.8 pp/GDP per unit with a p-value of 0.004.
- Analysis demonstrates robustness by showing a coefficient of +40.5 (p=0.012) when excluding the East Asian bloc.
- The model is described as absorbing approximately 4.2 pp of China's pre-2008 current-account residual.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown for the full underlying data, which may limit suitability assessment.
- Description metadata is limited; actual data quality and file formats require manual inspection after download.
