b.
c.
d.
A rise in the interest rate offered for dollar bank deposits (R$) causes the dollar to appreciate.
A rise in the interest rate offered for dollar bank deposits (R$) causes the dollar to depreciate.

R$ = R€ + (Ee€/$ – E€/$) / E€/$.
R$ = R€ - (Ee$/€ – E$/€) / E$/€.
11. If all interest rates stay unchanged, the theory of interest parity says that an increase in the
expected future value of the euro (Ee$/€) will
a. cause the value of the euro (E$/€) to increase immediately

a.
b.
c.
d.

Depends directly on R, and inversely on P and Y.
16. The aggregate demand for money can be expressed by:
a.
b.
c.
d.
e.
Md = P  L(R,Y)
Md = L  P(R,Y)
Md = Y  P(R, L)

17. Let L be the aggregate real demand for money (or, equivalently, the purchasing power of the
aggregate amount of money demanded, which is Md/P). An increase in
3
a.
b.
c.
d.
real GNP (Y) reduces the aggregate real money demand at a given interest rate (R).
real GNP raises the aggregate real money demand at a given interest rate.
the interest rate raises the aggregate real money demand at a given real GNP.
real GNP reduces aggregate nominal money demand for a given interest rate
18. When the curve of the supply of money is graphed with the interest rate (R) on the vertical axis and
the supply of money (Ms) on the horizontal axis, the curve is
a.
b.
c.
d.
e.
horizontal because Ms is set by the central bank.
vertical because Ms is set by the central bank.
vertical because Ms is set by the households and firms.
just a point because Ms and R are both set by the central bank.
vertical because R is set by the central bank.

a.
b.
c.
d.
e.
equilibrium in the money market

interest rate while a decrease in the money supply lowers the interest rate (R).
b. At any given price level, an increase in the money supply lowers the interest rate while a
decrease in the money supply raises the interest rate.
c. At any given output level, an increase in the money supply lowers the interest rate while a
decrease in the money supply raises the interest rate.
d. At any given price level and output, an increase in the money supply lowers the interest rate
while a decrease in the money supply raises the interest rate.
e. None of the above is true.
21. Using the equation for equilibrium in the money market, we can predict that an increase in
a. nominal output raises the interest rate while a fall in real output lowers the interest rate, given
the price level and the money supply.
b. real output decreases the interest rate while a fall in real output increases the interest rate,
given the price level.
c. real output raises the interest rate while a fall in real output lowers the interest rate, given the
money supply.
