We apply this methodology to analyze export specialization across countries and across regions within a country. In the country-level analysis, we find that, on average, granular comparative advantage leads to export specialization in 29% of industries, which account for 47% of total exports. We also show that 60% of the variation in export specialization across countries is explained by granular comparative advantage. The contribution of granularity to export specialization is more important across regions within a country than across countries.engExportsFundamental comparative advantageGranular comparative advantageEuropean UnionSpainRegionsExport superstarsFirm-level dataconference paper2026-01-30
