DESCRIPTION: Previous research conducted by the PIs has estimated commodity supply and commodity demand for each county in the United States using numerous government datasets. This research will build on that research and develop a doubly constrained gravity model that estimates both where the supply of each county’s commodity output is consumed and where the place of origin for the commodities demanded in each county. Once the regionally specific input-output accounts are populated a trade model will be applied to estimate the geographic source of those commodity inputs. Deriving multiregional social accounts requires complete estimation of inter-regional foreign and domestic commodity shipments. Because complete coverage of commodity-specific trade between all ports and county-pairs is not available the PIs propose developing a trade flow general equilibrium model to estimate county-to-county and county-to-port commodity shipments for tradable commodities and services among all US counties and ports.
