The demand for cars in Home is q = 30 – P and the supply of cars in Home is q = P. The demand for cars in Foreign is q=10–P and the supply of cars in Foreign is q = P.
a) Calculate the autarky equilibrium price and quantity in each country.
b) Who is the importer of cars and who is the exporter?
c) Write the import demand for Home and the export supply for Foreign.
d) Find the equilibrium world price under free trade. What is the amount of cars traded between the two countries?
e) Suppose the country that is the importer imposes a tariff of $2 per unit on car imports. Find the new equilibrium world price under the tariff. What is the amount of cars traded between the two countries now? Show this in a graph with the import demand for Home and the export supply for Foreign.
