Shipment Networks and Market Power in U.S. Poultry Procurement
Linking restricted Census shipment microdata to establishment records, I estimate a structural demand-and-supply system for the layer where U.S. poultry processors price to wholesale, retail, and food-service buyers. A simulated merger of the third- and fourth-largest firms raises average unit values by about 7 percent and converts 59 percent of downstream buyers' losses into deadweight loss.
