This article examines the extent of competition in the US salmon import market using a residual demand model. The estimated residual demand elasticity is coincident with the profit margin, which depends on market demand and competitors' supply as well as production cost. The estimation results reveal the following: (1) the forces driving the jointly dominant positions of Chilean and Canadian salmon exporters, (2) the suppliers' allocation decisions by product form, (3) the consequences of the antidumping order (AD) imposed on Chilean salmon, and (4) the impacts of the 2008 infectious salmon anemia (ISA) outbreak on Chilean exports, competitors' supply, and market demand.
