Homework Assignment 6
Chapter 15 – Questions
1. When the Euro appreciates, are you more likely to drink California or French
wine?
You are more likely to drink California wine because the euro
appreciation makes French wine relatively more expensive than
California wine.
2. “A country is always worse off when its currency is weak (falls in value).” Is
the statement true, false or uncertain? Explain your answer.
False. Although a weak currency has the negative effect of making it
more expensive to buy foreign goods or to travel abroad, it may help
domestic industry. Domestic goods become cheaper relative to foreign
goods, and the demand for domestically produced goods increases.
The resulting higher sales of domestic products may lead to higher
employment, a beneficial effect on the economy.
3. In a newspaper, chose one exchange rate from each of the regions listed in
Following the Financial News box on p347. Which of these currencies have
appreciated, and which have depreciated since June 23, 2010?
4. If the Japanese price level rises by 5% relative to the price level in the United
States, what does the theory of purchasing power parity predict will happen
to the value of the Japanese Yen in terms of US dollars?
It predicts that the value of the yen will fall 5% in terms of dollars.
5. If the demand for a country’s exports falls at the same time that tariffs on
imports are raised, will the country’s currency tend to appreciate or
depreciate in the long run?
In the long run, the fall in the demand for a country’s exports leads to
a depreciation of its currency, but the higher tariffs lead to an
appreciation. Therefore, the effect on the exchange rate is uncertain.
6. In the mid-to-late 1970’s, the yen appreciated relative to the dollar even
though Japan’s inflation rate was higher than America’s. How can this be
explained by an improvement in the productivity of Japanese industry
relative to American industry?
Even though the Japanese price level rose relative to the American,
the yen appreciated because the increase in Japanese productivity
relative to American productivity made it possible for the Japanese to
continue to sell their goods at a profit due to the high value of the yen.
Predicting the future
7. The president of the United States announces that he will reduce inflation
with a new anti-inflation program. If the public believes him, predict what
will happen to the exchange rate for the U.S. dollar vs. other currencies.
The dollar will appreciate. Because expected U.S. inflation falls as a
result of the announcement, there will be an expected appreciation of
the dollar and so the expected return on dollar assets will rise. As a
result, the demand curve will shift to the right and the equilibrium
value of the dollar will rise.
8. If the Bank of England prints money to reduce unemployment, what will
happen to the value of the pound in the short run and the long run?
The pound depreciates but overshoots, declining by more in the short
run than in the long run. Consider Britain to be the domestic country.
The rise in the money supply leads to a higher domestic price level in
the long run, which leads to a lower expected future exchange rate. In
addition, the rise in the money supply lowers the domestic interest
rate on pound assets. Both of these changes lower the expected return
on pound assets at any given exchange rate, shifting the demand curve
to the left. The short-run outcome is a lower value of the pound.
However, in the long run, the domestic interest rate returns to its
previous value, and the demand curve shifts back to the right
somewhat. The exchange rate rises to some extent, but still remains
below its initial level.
9. If the Indian government unexpectedly announces that it will be imposing
higher tariffs on foreign goods one year from now, what will happen to the
value of the Indian rupee today?
The Indian rupee will appreciate. The announcement of tariffs will
raise the expected future exchange rate for the rupee and so increase
the expected appreciation of the rupee. This means that the demand
for rupee-denominated assets will increase, shifting the demand curve
