Using a theoretical and empirical spatial equilibrium model, we examine the effect of the Chinese 25% tariff on the world sorghum market under various market structures. The effects of the tariff are less pronounced under bilateral monopoly than under perfect competition. Specifically, the reallocations of trade caused by the tariff are lessened as the United States uses its market power to mitigate adverse effects. This reduces the tariff's impacts on prices, production, consumption, and welfare for most countries. However, the calibration revealed that the United States and China do not exert significant market power on the world sorghum market and that international sorghum trade is more accurately represented by perfect competition.

China targeted U.S. soybeans, among other commodities, for its recent retaliatory tariff chiefly because of the sheer volume of its imports from the United States. We develop a theoretical and empirical spatial equilibrium trade model to analyze the effects of the 25% Chinese soybean tariff on the United States, China, and nine other major soybean trading regions. Both the United States and China incur welfare losses as a result of the tariff, but Brazil experiences a large net gain. The United States mitigates some of its losses by reallocating trade to other importers, but at a cost to smaller exporters such as Canada.
