The Agri-Food Economic Data System (Ag-FEDS) is an integrated system of economic data that elaborates the linkages between all production and consumption activities throughout the U.S. economy. This data system incorporates developments to provide the most complete accounting of the U.S. food economy to date and is a flexible modeling platform that supports research in this area. This report makes three extensions to Ag-FEDS in preparation for multiplier analysis: (1) complete passthrough accounting of food commodities, (2) inclusion of non-farm food commodities in the food supply chain, and (3) partitioning import/export commodity flows to avoid re-exporting imports. Ag-FEDS is used as the underlying data source for two food-system-specific multiplier models: the Food Dollar and the Resource Requirements of Food Demand. The multiplier models based on the extended Ag-FEDS data are then derived in this report. The resulting output data of this analysis present greater detail and insights into the U.S. food economyʼs costs and resource use than previously available.
