The tarrif's revenue effect (the import tariff multiplied by the quantity of oil imported) can be broken into two components: • Domestic revenue effect • Terms-of-trade effect On the previous graph, use the green rectangle (triangle symbols) to indicate the domestic revenue effect of the tariff. Then use the purple rectangle (diamond symbols) to indicate the terms-of-trade effect. Now consider the effect of the tariff on welfare in the United States. On the previous graph, use the black triangles (plus symbols) to indicate the deadweight loss caused by the tariff. True or False: National welfare in the United States increases as a result of a $60-per-barrel tariff on oil imports. True False
The following graph shows the domestic market for oil in the United States, where SDSD is the domestic supply curve, and DDDD is the domestic demand curve. Assume the United States is considered a large nation, meaning that changes in the quantity of its imports due to a tariff influence the world price of oil. Under free trade, the United States faced a total supply schedule of SD+WSD+W, which shows the quantity of oil that both domestic and foreign producers together offer domestic consumers. In this case, the free-trade equilibrium (black plus) occurs at a price of $240 per barrel of oil and a quantity of 9 million barrels. At this price, the United States imports 6 million barrels of oil.
Suppose the U.S. government imposes a $60-per-barrel tariff on oil imports.
