Part II. Problem-solving questions

18. Fill in the blanks in the following exchange rate table (keep four digits after the

decimal point for each answer):

Your Answer:
Blank A: ___________________

Blank B: ___________________

Blank C: ___________________

Blank D: ___________________

19. If the Federal Reserve raises dollar interest rates, this induces investors into dollar

securities and raises the demand for dollar-denominated assets. Fed’s tightening
of monetary policy will shift the “demand for dollars” A (up to the right or
down to the left). The U.S. dollar will B (appreciate/depreciate).

Your Answer:
A:_______________________ (up to the right/down to the left)

B:_______________________ (appreciate/depreciate)

Suppose that a recession or deflation in Japan reduces the Japanese demand for
dollars. This will shift “demand for dollars” curve C (up to the right/down
to the left/up to the left/down to the right) and lead the dollar to D
(appreciate/depreciate).

Your Answer:

C:_______________________ (up to the right/down to the left/up
to the left/down to the right)

Currency
Units of foreign currency

foreign currency

Canada (Dollar) 1.0372 Blank A

Japan (Yen) 76.9050 Blank B

Mexico (Peso) 13.9660 0.0716

Switzerland (Frank) 0.9186 1.0886

20. For a market basket of goods, it costs $1000 in the United States, and 10,000

pesos in Mexico.

A. If the exchange rate is 10 pesos per dollar, where would you buy these
goods (assuming there is free trade between the United States and Mexico)?

a. Definitely in the United State, not Mexico
b. Definitely in Mexico, not the United States
c. Indifferent since the prices in the two countries are the same

Your Answer: __________________

B. Suppose the United States has a 2% inflation so that the dollar price

increases from $1,000 to $1,020. In the meantime, Mexico has a 12.2%
inflation so that the price in Mexico increases from 10,000 pesos to 11,220
pesos. At the old exchange rate of 10 pesos per dollar, the Mexican price
is now $1,122 (=11,220 peso / (10 peso/$)). The price now is higher in
Mexico than in the United States at the old exchange rate. Mexicans
would buy from the United States. The increased demand for U.S. goods
translates into increased demand for U.S. dollars. The dollar would
appreciate. What is the new equilibrium exchange rate according to
purchasing power parity (assuming the U.S. dollar price is set at $1,020)?

Your Answer: __________________ peso/$

C. Does the dollar appreciate or depreciate? By how much?

Your Answer: _________________ (appreciate/depreciate)

By how much: _________________% (provide an absolute number; keep
two digits after the decimal point)

D. Does the peso appreciate or depreciate? By how much?

Your Answer: _________________ (appreciate/depreciate)

By how much: _________________% (provide an absolute number; keep
two digits after the decimal point)
