Sharing risk: General Average, 6th-21st Centuries
Conference in Genoa, Archivio di Stato, 16-18 May 2019

The conference is dedicated to the analysis of the historical evolution of General and Particular Averages. These are mechanism for the redistribution of costs in maritime trade which are still used today to proportionally redistribute amongst all interested parties (ship owner, freighter and cargo owners) the expenses which can befall ships and cargoes from the time of lading until their unloading (due to accidents, jettison, capture and unexpected expenses). Within the project Average-Transaction Costs and Risk Management during the First Globalization (Sixteenth-Eighteenth Centuries) - (ERC Consolidator Grant n. 724544), the conference will present its preliminary results for the medieval and early modern developments in Europe and the Islamic world.
