Aggregation, by contrast, eliminates this problem. Therefore, testing the total value of imports and exports with the sum of the same trade flows as registered by their partner countries' statistics, leads to more encouraging conclusions on the aggregate data. Our results strengthen considerably one's trust in the reliability of pre-World War 11 foreign trade statistics. Diversity in individual countries' accuracy indexes can be partially explained by differences in freight factors and also by minor differences in compilation.application/pdfengAtribución-NoComercial-SinDerivadas 3.0 Españaresearch articleEconomíaHistoriaopen access2593273Explorations in Economic History28
