answers for part A, B and C

2. The IS - LM -UIP Model
Consider an economy that experiences an increase in
consumer confidence. Let UIP stand for the uncovered
interest parity condition.
Suppose the economy has a flexible exchange rate. In
an
IS – LM – UIP diagram, show the effect of the increase in
consumer confidence on output, the interest rate, and the
exchange rate. ( You must draw the graphs)
b. (Following (a)) How does the change in the exchange
rate, by itself, tend to affect
output? Does the change in the exchange rate dampen
(make smaller) or amplify (make larger) the effect of the
increase in confidence on output?
Suppose instead the economy has a fixed exchange rate.
In an Is - LM – UIP
diagram, show effect of the increase in consumer
confidence on output, the interest rate. What must
happen to the money supply in order to maintain the
fixed exchange rate? ( You must draw the graphs)
d. How does the effect on output in this economy, with
fixed exchange rates,
compared to the effect you found for the economy for
part (a), with flexible exchange rates?
