International Trade Using Demand and Supply If there were no international trade, the equilibrium would be found, as usual, at the intersection of the domestic demand and domestic supply curves at PNo trade, and QNo trade. With trade, U.S. consumers can buy as many semiconductors as they want at the world price, and at this price U.S. consumers demand QdFree trade units. At the world price, the difference between domestic demand, QdFree trade, and domestic supply, QsFree trade, is made up by imports.
