Current account + financial account + capital account = 0

Answer:

True. The main reasons are due to the fact that data collected or received

data

difficult.

Discuss
the
effects
of
a
rise
in
the
interest
rate
paid
by
euro
deposits
on
the
exchange rate.


Answer:

There
are
two
effects
to
consider.
If
we
make
the
unrealistic
assumption
that the expected exchange rate will not change, then a rise in the interest rate paid by
Euro deposits causes the dollar to depreciate. However, if the expected exchange rate
were to rise, then the current exchange rate would also rise. (See figure 13-6 from the
text.)

3

Using a figure describing both the U.S. money market and the foreign exchange
market, analyze the effects of a temporary increase in the European money supply on
the dollar/euro exchange rate.


Answer:

An increase in the European money supply will reduce the interest rate on
the
euro
and
thus
will
cause
the
schedule
of
the
expected
euro
return
expresses
in
dollars
to
shift
down,
causing
a
reduction
in
the
dollar/euro
exchange
rate,
i.e.,
an
appreciation
of
the
U.S.
Dollar.
The
euro
depreciates
against
the
dollar.
The
U.S.
money demand and money supply are not going to be affected, and thus the interest
rate in the U.S. will remain the same.

A) causes a more than proportional increase in its price level.


B) causes a less than proportional increase in its price level.

C) the exchange rate smoothly depreciates in the short run.


D) the exchange rate smoothly appreciates in the short run.


E) None of the above.


Answer:

A

6


a
change
in
the
money
supply
creates
immediate
demand
and
cost
pressures
that
eventually lead to future increase in the price level.


Answer: The statement is true. The pressures come from three main sources: excess
demand for output and labor; inflationary expectations; and, raw material prices.



7

The long run effects of money supply change:


A)
ambiguous
effect
on
the
long- run
values
of
the
interest
rate
or
real
output,
a
proportional change in the price level's long- run value in the opposite direction.


B


proportional
effect
on
the
long-run
values
of
the
interest
rate
or
real
output,
a
proportional change in the price level's long-run value in the same direction.


C) no effect on the long-run values of the interest rate or real output, a proportional
change in the

price level's long-run value in the same direction.


D) no effect on the long-run values of the interest rate or real output, no change in the
price level's long-run value.


E)
ambiguous
effect
on
the
long-run
values

the

rate
or
real
output,
A
disproportional change in the price level's long-run value in the same direction.
