An economist by training, Béatrice Dedinger turned to economic history by devoting her PhD thesis to German trade history. She has given teachings on economics, economic history and European economy. For the last ten years or so, her research has extended to the building and exploitation of a historical trade database of all of the world’s countries that is available on the RICardo website (

Research project

Béatrice Dedinger is the scientific director of the RICardo project (Research on International Commerce) launched at the beginning of the 2000s with the aim of providing the scientific international community with a trade database covering bilateral trade of all of the world’s countries over the period 1800-1938.

Two significant outcomes were produced in 2017, more than ten years after the launching of the project: a set of about 300 000 bilateral trade data built from digitized trade archives and a website providing innovative visualizations of the data. 

A second stage of work is underway that should be completed by 2022. Three objectives are being aimed at. First, to supplement the trade database with new archives collected at the Bibliothèque nationale de France. Second, to add a geographical and political dimension in the website thanks to the creation of a base of the world’s entities since the beginning of the 19th century indicating the development of their political status and their geo-localization. Third, these two databases will allow for the development of a new feature that will provide the user with a cartography of trade flows.
