Exporter-level customs data measures the concentration of export value among the largest firms. The dataset provides the share of total export value controlled by the top 5% of exporters for various countries and years. It is produced by the World Bank's Exporter Dynamics Database.
Use Cases
- Analyze the relationship between the 'Share of top 5% Exporters' metric and a country's GDP growth using time-series regression.
- Compare export market concentration across different countries by ranking them based on the top exporter share indicator.
- Model the stability of a country's export value over time using the concentration metric as a predictor feature.
- Investigate if changes in trade policy correlate with shifts in the share of export value held by the largest firms.
Strengths
- Data is derived from official customs transaction records, providing a factual foundation.
- Indicator is calculated at the country-year level, enabling longitudinal and cross-country analysis.
Limitations
