Marketing margins of food products in European countries using input-output tables

This paper computes marketing margins of EU-27 agri-food systems using Input-Output tables (IOTs); such estimation is more accurate than those yielded using macroeconomic aggregated data from national accounts. Some relevant economics flows are then observables: a) Exchange relationships among activity branches of agri-food system; b) Production uses splitted between intermediate and final consumption; c) Value and variation of whole margins for branch and for whole system; d) margins variations during the strong fluctuation in raw agricultural prices (price spike). When chain-linked price tables will be available for more years it will be possible to separate the price component and quantity component of value changes
