Use Cases

• Analyze trends in export market concentration over time using the HHI value per country-year.
• Model the impact of trade policy on market diversification by correlating HHI with other country-level economic indicators.
• Benchmark a country's export structure against regional peers using the comparative HHI scores.
• Investigate the stability of export earnings by examining HHI time-series data for volatility.
