The equilibrium exchange rate is at A, $1.25/euro. Suppose the European Central Bank
pegs its currency at $1.00/euro. Speculators expect that the value of the euro will rise
and this shifts the demand curve for euro to D2. After the shift,
A) there is a shortage of euro equal to 1,000 million.
B) there is a surplus of euro equal to 400 million.
C) there is a shortage of euro equal to 800 million.
D) there is a surplus of euro equal to 500 million.
Table 14-3
Suppose OPEC has only
two producers, Saudi Arabia and Nigeria. Saudi Arabia has far more oil reserves and is
the lower cost producer compared to Nigeria. The payoff matrix in Table 14-3 shows
the profits earned per day by each country. “Low output” corresponds to producing the
OPEC assigned quota and “high output” corresponds to producing the maximum
capacity beyond the assigned quota. What is the Nash equilibrium in this game?
A) In the Nash equilibrium both Saudi Arabia and Nigeria produce a low output and
earn a profit of $100 million and $20 million respectively.
B) In the Nash equilibrium both Saudi Arabia and Nigeria produce a high output and
earn a profit of $60 million and $20 million respectively.
C) In the Nash equilibrium Saudi Arabia produces a low output and earns a profit of
$80 million and Nigeria produces a high output and $30 million respectively.
D) There is no Nash equilibrium.
