Import Tariff in a Small Nation
Suppose that nation A is a small nation with demand and supply of commodity X given by Qd = 120 – 20P and Qs = 20P, respectively. Assume that the free trade price of commodity X is $1, and nation A imposes a 150% import tariff on commodity X. Draw a figure similar to Figure 8.1 in Salvatore and compute the following:
A. (2 points) nation A’s pre-trade level of price, production and consumption
B. (2 points) nation A’s price, production, consumption and imports of commodity X under free trade
C. (4 points) nation A’s price, production, consumption and imports of commodity X after the imposition of the tariff
D. (2 points) consumption, production, trade and revenue effects of the import tariff
E. (4 points) dollar value of the consumer surplus and producer surplus before and after the imposition of the tariff
F. (2 points) dollar value of the deadweight loss of the import tariff
