For example, should the United States use a tariff or an import quota to protect its automobile industry against competition from Japan and South Korea?,Slide 8-4,Copyright 2003 Pearson Education,

5、ecific tariff of $10 on each imported bicycle with an international price of $100 means that customs officials collect the fixed sum of $10. Ad valorem tariffs Taxes that are levied as a fraction of the value of the imported goods Example: A 20% ad valorem tariff on bicycles generates a $20 payment
6、on each $100 imported bicycle.,Slide 8-6,Copyright 2003 Pearson Education, Inc.,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

Both countries consume and produce wheat, which can be c
8、ostless 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
9、 price in Foreign and lowers its price in Home until the initial difference in prices has been eliminated.,Basic Tariff Analysis,Slide 8-8,Copyright 2003 Pearson Education, Inc.,To determine the world price (Pw) and the quantity trade (Qw), two curves are defined: Home import demand curve Shows the
10、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
11、 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,Slide 8-9,Copyright 2003 Pearson Education, Inc.,PA,P2,P1,Figure 8-1: Deriving Homes Import Demand Curve,Basic Tariff Analysis,Slide 8-1

A small country is a country that cannot affect its terms of trade no matter how much it trades with the rest of the world.

Suppose Home imposes a tax of $2 on every bushel of wheat imported. Then shippers will be unwilling to move the wheat unless the price difference between the two markets is at least $2.
