Homework (Ch 12)
The following graph shows the short-run supply schedule (S) and demand schedule (D) for the euro. S denotes the long-run supply schedule of euros. The initial equilibrium exchange rate is $1.20 per euro. Suppose that the demand for euros increases to D.
On the graph, use the tan point (dash symbol) to indicate the long-run equilibrium exchange rate.
Note: Dashed drop lines will automatically extend to both axes.

QUANTITY (EUROS)
The dollar depreciates to $2.10 per euro.
The price of U.S. exports decreases, and the quantity of U.S. exports demanded increases. The supply schedule of euros becomes more elastic, as shown by S'. Referring to the quantity of euros supplied, it increases due to events that led to the long-run equilibrium exchange rate.
Step 1: The dollar appreciates to $1.50 per euro.
