Slide 8-6 • A compound duty (tariff) is a combination of an ad valorem and a specific tariff. • Modern governments usually prefer to protect domestic industries through a variety of nontariff barriers, such as: – Import quotas – Limit the quantity of imports – Export restraints – Limit the quantity of exports Basic Tariff Analysis
Basic tariff analysis Supply, Demand, and Trade in a Single Industry Suppose that there are two countries(Home and Foreign) Both countries consume and produce wheat, which can be costless transported between the countries In each country, wheat is a competitive industry Suppose that in the absence of trade the price of wheat at Home exceeds the corresponding price at Foreign This implies that shippers begin to move wheat from Foreign to Home The export of wheat raises its price in Foreign and lowers its price in Home until the initial difference in prices has been eliminated Copyright C 2003 Pearson Education, Inc Slide 8-7

Slide 8-7 ▪ Supply, Demand, and Trade in a Single Industry • Suppose that there are two countries (Home and Foreign). • Both countries consume and produce wheat, which can be costless transported between the countries. • In each country, wheat is a competitive industry. • Suppose that in the absence of trade the price of wheat at Home exceeds the corresponding price at Foreign. – This implies that shippers begin to move wheat from Foreign to Home. – The export of wheat raises its price in Foreign and lowers its price in Home until the initial difference in prices has been eliminated.

Basic tariff analysis To determine the world price(P) and the quantity trade(Ow), two curves are defined Home import demand curve Shows the maximum quantity of imports the Home country would like to consume at each price of the Imported goo d That is. the excess of what home consumers demand over what Home producers supply: MD=D(P)-S(P Foreign export supply curve Shows the maximum quantity of exports Foreign would like to provide the rest of the world at each price That is, the excess of what Foreign producers supply over what foreign consumers demand: XS=S(P-D(P Copyright C 2003 Pearson Education, Inc Slide 8-8

Slide 8-8 ▪ To determine the world price (Pw) and the quantity trade (Qw), two curves are defined: • Home import demand curve – Shows the maximum quantity of imports the Home country would like to consume at each price of the imported good. – That is, the excess of what Home consumers demand over what Home producers supply: MD = D(P) – S(P) • Foreign export supply curve – Shows the maximum quantity of exports Foreign would like to provide the rest of the world at each price. – That is, the excess of what Foreign producers supply over what foreign consumers demand: XS = S*(P*) – D*(P*) Basic Tariff Analysis
