Textbook Problem

# Assume the United States is an importer of televisions and there are no trade restrictions. US consumers buy 1 million televisions per year, of which 400,000 are produced domestically and 600,000 are imported,a. Suppose that a technological advance among Japanese television manufacturers causes the world price of televisions to fall by $100. Draw a graph to show how this change affects the welfare of U.S. consumers and U.S. producers and how it affects total surplus in the United States.b. After the fall in price, consumers buy 1.2 million televisions, of which 200,000 are produced domestically and 1 million are imported. Calculate the change in consumer surplus, producer surplus, and total surplus from the price reduction.c. If the government responded by putting a$100 tariff on imported televisions, what would this do? Calculate the revenue that would be raised and the deadweight loss. Would it be a good policy from the standpoint of U.S. welfare? Who might support the policy?d. Suppose that the fall in price is attributable not to technological advance but to a \$100 per television subsidy from the Japanese government to Japanese industry. How would this affect your analysis?

Subpart (a):

To determine
The impact of technological advancement on TV production.

Explanation

When the technological advancement in production reduces the world price of televisions, the impact on the importer will be as follows: the importing price will fall, which will reduce the domestic price for televisions; this will increase the demand for the televisions and increase the consumer surplus as well as the total surplus. Further fall in the domestic price will reduce the domestic supply of the televisions and thus, the producer surplus will fall. This means that the amount of imports will further increase. This can be illustrated as follows:

The world price was initially P1, where the consumer surplus was the area of A+B, producer surplus was the area of C+G and the total surplus was the area of A+B+C+G. The quantity of televisions imported is denoted by the Import1 on the graph. When the world price falls to P2 (P1 - 100), the consumer surplus increases to the area of A+B+C+D+E+F, which means that the consumer surplus increases by the area of C+D+E+F...

Subpart (b):

To determine
