PRACTICE QUESTIONS
1. You recently read a headline that states: “The U.S. loses $500 billion a year to trade with
China.” This amount would be included as part of the U.S. current account deficit. How is this
headline misleading? How do these transactions affect the loanable funds framework?
Solution
1. While the United States does run a trade deficit with China, it is incorrect to say the trade
deficit is a loss for the country. First, the United States receives goods and services from China.
Second, as you have learned, the current account plus the financial account must equal zero.
Since the United States has a current account deficit, it must be offset by a financial account
surplus. In other words, as the United States runs a trade deficit with China, China returns the
extra capital by purchasing U.S. assets. In our loanable funds graph, the financial account surplus
will shift the supply of funds to the right, causing interest rates to fall.
2. During his presidency, Donald Trump attempted to alleviate the U.S. trade deficit by passing a
series of tariffs on Chinese exports. Prior to President Trump taking office, the U.S. had an
, average tariff rate of 3.1% on Chinese exports but by February of 2020 the average tariff rate had
increased to 19.3%. During the same time period, the U.S. dollar appreciated from 6.27 Chinese
yuan to 7.10 yuan per U.S. dollar. Using the foreign exchange market explain how the
implementation of the tariffs would change the yuan/dollar exchange rate. Is this consistent with
what we observed in the data?
Solution
2. Tariffs placed on Chinese exports will increase the price of Chinese goods for U.S. residents,
causing U.S. residents to decrease their consumption of these goods. As U.S. residents reduce
their purchases of Chinese goods, the demand for Chinese yuan will decrease. The decrease in
demand for Chinese goods will cause the dollar to appreciate relative to the yuan. It’s worth
noting that as the average tariff rate increased by 16.2%, the yuan depreciated by nearly 12%.
3. With oil priced in U.S. dollars, most Middle Eastern and other oil-producing countries have a
fixed exchange rate peg to the U.S. dollar. What are the pros and cons of these countries pegging
their currency to the U.S. dollar?
Solution
3. For most oil-producing countries, the benefits of pegging to the dollar far outweigh the costs.
For decades, the United States has been the largest purchaser of oil and has the most stable
exchange rate. Pegging to the U.S. dollar minimizes oil price fluctuations and links their
