(a) What is the equilibrium exchange rate and quantity?
(b) Suppose the European Central Bank decides to counter rampant growth by reducing the money supply
to moderate the European economy. How will the supply and demand situation for the euro change?
What likely effect will this have on the equilibrium exchange rate and quantity?
(c) Suppose that inflation increases in Europe. How will the supply and demand situation for the euro
change? What likely effect will this have on the equilibrium exchange rate and quantity?
(d) Suppose Europeans decide to take more vacations in the United States. Using the data in the table
above, calculate the new equilibrium. Assume the subsequent shift(s) (if one or more occur), causes
the affected curve(s) to shift by 50 in the appropriate direction.

interest rates. Facing the same economic conditions, the European Central Bank decides to increase

subsequent shift(s) (if one or more occur), causes the affected curve(s) to shift by 50 in the appropriate
direction.

34. Describe the three major disadvantages of flexible exchange rates.
First, flexible exchange rates are subject to great volatility, and thus create uncertainty in exchange rate
markets. This uncertainty can adversely affect trade because it creates more risks for those businesses that
35. The graph below shows a change in the demand for Swiss francs from D1 to D2. What would happen when

(b) Instability of the economy due to wide fluctuations.
(c) This system is considered a non-system.
(d) Occasional interventions are used to stabilize the economy.
(e) The purchasing power parity moves the system to equilibrium.
(f) Payment deficits tend to persist.
37. How does a fixed exchange rate system work? How can a nation maintain its fixed exchange rate?

38. Discuss the difference in the foreign exchange market when a fixed exchange rate policy is used, as
opposed to a floating exchange rate.

exchange rate policy.
40. Suppose the U.S. Dollar were fixed to the Mexican Peso and the demand for the peso decreased. Examine,
graphically and in discussion, the actions that would be required by the government.
41. Discuss the relationship between the foreign exchange reserves and the domestic money supply.
42. Describe the problem that will arise if there is a sustained difference between the fixed and equilibrium
exchange rates.

about correcting it.
44. (Consider This) Discuss the effect of China’s fixed exchange rate policy.
45. Provide methods a country can use they experience a continual decrease in their foreign exchange reserves.
46. Explain the problems with exchange rate controls.
Exchange rate controls or capital controls would require foreign currency obtained in a trade transaction to
be sold to the government. Foreign currency needed for an import transaction would be bought from the
government. The government would ration foreign currency to meet currency exchange needs.

The persistent trade deficits in the United States in recent years were the result of several factors. First,
there was more rapid growth in the domestic economy than in the economies of several major trading
partners. This factor caused U.S. imports to rise more than U.S. exports. Second, the United States

54. “Trade deficits are a mixed blessing.” Interpret and elaborate.
55. (Last Word) Examine the decision to develop a shared currency across economies.
The primary benefit of developing a shared currency across economies is the ease of trade. When countries
share a currency the transaction costs associated with trade are greatly reduced. There is no need to
determine the conversion rate and prices are no longer given in multiple currencies. The exchange rate risk
associated international business and trade is also eliminated.
There are also costs of a shared currency. First, the loss of monetary policy independence. When economies
decide to share a currency they must also share monetary policy. If one country under the currency is
