Explain the following patterns of trade using the Heckscher-Ohlin model.

2a) Explain the following patterns of trade using the Heckscher–Olin model: France exports wine to the United States and the United States exports movies to France.

1. This occurs because consumers in the United States like movies more than they like wine.

2. This occurs because the United States has a larger endowment of factors of production for movies relative to France, while France has a relatively larger endowment of factors of production for wine.

3. This occurs because the alternative is autarky, which the Heckscher–Olin model describes as being a worse state than international trade.

2b) Explain the following patterns of trade using the Heckscher–Olin model: Brazil exports shoes to the U.S. and the U.S. exports shoe-making machinery to Brazil.

Check Your Understanding 5-4Questions 1 and 2

1) In 2002 the U.S. imposed tariffs on steel imports, which are an input in a large number and variety of U.S. industries. Why is political lobbying likely to be more effective in eliminating these tariffs than eliminating tariffs on consumer goods, such as sugar or clothing?

1. It’s easier for a few businesses to coordinate a success lobbying effort than it is for many consumers.

2. It’s easier for consumers to organize a lobbying effort because they are voters.

2) The WTO has increasingly found itself adjudicating trade disputes that involve not just tariffs and quotas, but restrictions based on quality, health, and environmental considerations. These restrictions are likely to be in violation of a free-trade agreement when the domestic producers are subject to the same restrictions as foreign competitors.

1. True

2. False
