2. A U.S. firm expects to receive payment of €1.5 million in 90 days for exports to France. At an

7. The demand for money is given by Md = P x Y x L(i), where P is the price level, Y is real income and i

16. The following is an example of Apple hedging its foreign currency risk:
A) needing to pay 9,000 yen per iPhone to its suppliers in a month, Apple makes a forwardexchange deal to buy yen.
B) needing to pay 9,000 yen per iPhone to its suppliers in a month, Apple makes a forward-exchange deal
to sell yen.
C) needing to pay 9,000 yen per iPhone to its suppliers in a month, Apple buys yen at a spot-exchange
1 month from now.
D) needing to pay 9,000 yen per iPhone to its suppliers in a month, Apple sells yen at a spot-exchange
1 month from now.
17. Which major actor is at the center of the foreign exchange market?

18. If the dollar interest rate is 10 percent and the euro interest rate is 6 percent, then
A) an investor should invest only in dollars.
B) an investor should invest only in euros.
C) an investor should be indifferent between dollars and euros.
D) It is impossible to decide between the two, given the information.
19. Suppose that the one-year forward price of euros in terms of dollars is equal to \$1.113 per euro.
Further, assume that the spot exchange rate is \$1.05 per euro, and the interest rate on dollar deposits is 10
percent and on euro it is 4 percent. Show that the Covered Interest Parity condition holds in this case. [7
points]
One has to plug in the numbers to check whether
Dollar interest rate = (1/spot rate)* Euro interest rate * Forward rate
holds or not. It does indeed.
20. Dollar euro exchange rate is 1.35\$/euro. Dollar yen exchange rate is 0.0125 \$/yen. What
would be the euro-yen exchange rate for no-arbitrage to hold? [6 points]
0.0125/1.35 euro/yen
1990 the same had gone to C\$392. In the US, the price of an identical basket rose from \$100 to
\$336. In 1970 the dollar/looney exchange rate was 1, whereas by 1990 the exchange rate was
1.16 C\$ per US\$. What would it cost a Canadian to buy the US consumption basket in 1990?
For a Canadian the cost of a 1990 US basket is 1.16*336 = 389.8 C\$
For a US resident the cost of a 1990 Canadian basket is 392/1.16 = 337.9 \$
22. A big Mac costs 10 yuans in China, while it costs \$4 in the US. The yuan/\$ exchange rate is
7. Is yuan undervalued or overvalued relative to its value predicted by the law of one price for
big Macs? By what percentage? (6 points)
LOOP will require yuan/\$ exchange rate to be 10/4 = 2.5 yuans. But it is 7 yuan – it is too
cheap in the market – i.e., undervalued. The undervaluation is by (7-2.5)/2.5 = 4.5/2.5 = 1.8.
One would say that it is undervalued by 180%. The yuan will have to depreciate by 180%
to reach its value predicted by LOOP.
23. Suppose EU prices and outputs remain constant. US output is constant but the Fed announces
that US money supply will now onwards grow at 10%, while previously it was kept constant.
Assuming PPP holds, what is the implication for \$-euro exchange rate? Assume that the money
demand does not depend on the nominal interest rates. That is the real money demand is given by
the quantity theory of money. (6 points)
The dollar/euro exchange rate is the ratio of P_US and P_EU by PPP. Nothing happens to
P_EU – it is clear. If money supply begins growing by 10%, prices begin growing by 10%
too by the quantity theory equation which says that M/P = L Y. Since the RHS is constant
for the LHS to be constant P_US grows by 10% too. Then the exchange rate grows by 10%
too. However, there is no change at the time when the policy is announced, because the
Money supply does not change at that moment.
24. Bonus Question (4 points): Please refer to the Big Mac Index data posted on the class
website. Which country’s currency is most overvalued and most undervalued? Give one main
reason for the Big Mac price differences across countries.
Most Overvalued: Switzerland. Most undervalued: Ukraine. A Big Mac is made using both
traded and non-traded (labor) goods/services. Richer countries have higher real wages and
as a result a Big Mac costs more in those countries.
