At the target exchange rate of $0.121, the quantity of yuan demanded exceeded the quantity of yuan supplied, creating the shortage depicted in the diagram. Without any intervention by the Chinese government, the U.S. dollar price of the yuan would be bid up, causing an appreciation of the yuan.

Rubric for FRQ 2 (10 points)
1 point: The vertical axis is labeled “Exchange rate (Australian dollars per U.S. dollar)” and the horizontal axis is labeled “Quantity of U.S. dollars.”
1 point: Demand is downward-sloping and labeled; supply is upward-sloping and labeled.
1 point: The equilibrium exchange rate and equilibrium quantity of dollars are labeled on the axes at the point where the supply and demand curves intersect.
1 point: The U.S. interest rate falls.
1 point: There are an increase in the capital flow into Australia and an increase in the capital flow out of the United States.
1 point: The lower interest rate in the United States reduces the incentive to invest in the United States and increases the incentive to invest in Australia.
1 point: The supply of U.S. dollars increases.
1 point: The demand for U.S. dollars decreases.
1 point: The exchange rate falls (the U.S. dollar depreciates).
1 point: The lower exchange rate leads to more exports from the United States to Australia (they are cheaper now) and fewer imports into the United States from Australia (they are more expensive now). When exports increase and imports decrease, U.S. aggregate demand increases.
