SCENARIO: IS-LM-FX
Assume that initially the IS curve is given by
IS_{1}: Y = 24 – 3T – 60i + 4G,
Assume as well that the price level P is 1, and the LM curve is given by
LM_{1}: M = Y(2- i).
And that the forex market equilibrium is characterized by:
i = ([E^{e} / E]-1) + 0.20
Finally, assume that T=3, G=3, and the home interest rate is 0.3 (i.e. 30%).
7. (Scenario: IS-LM-FX) What is the level of output according to the IS_{1} curve?
A) 5.5
B) 6
C) 9
D) 103
8. (Scenario: IS-LM-FX) If the level of output is the one determined by the IS_{1} curve, what is the equilibrium level of home money supply?
A) 15.3
B) 1.8
C) 5.2
D) 9
9. (Scenario: IS-LM-FX) If the expected exchange rate is equal to 1, how much should the current value of the spot exchange rate be?
A) 1.0
B) 1.1
C) 0.71
D) 0.91
SCENARIO: EXCHANGE RATE CHANGE: Suppose that Canada decides to peg its dollar ($C, or the loonie) to the U.S. dollar at an exchange rate of $C1 = $US1.
10. (Scenario: Exchange Rate Change) Will there be pressure for the Canadian dollar to change in value against the U.S. dollar because of a rightward shift of the U.S. IS curve?
A) Yes, there will be pressure for the Canadian dollar to appreciate.
B) Yes, there will be pressure for the Canadian dollar to depreciate.
C) No, there will be no pressure for Canadian dollar to change in value.
D) Not enough information.
11. (Scenario: Exchange Rate Change) What must the Bank of Canada do (after observing a rightward shift in the U.S. IS curve) to maintain Canada’s peg of $C1 = $US1 against the U.S. dollar?
A) It must use an expansionary monetary policy.
B) It must use a contractionary monetary policy.
C) It does not need to change its monetary policy.
D) None of the above.
12. Assume Britain maintains a fixed exchange rate with Germany. Suppose that Germany increases its interest rates. Assuming Britain maintains its fixed exchange rate (using monetary policy), the likely impact on the British economy would be:
A) a boom
B) a recession
C) an appreciation of the pound
D) a depreciation of the pound
In this question assume all dollar units are real dollars in billions, so $300 means $300 billion. It is year 0. Argentina thinks it can find $300 of domestic investment projects with an MPK of 40% (each $1 invested pays off $0.40 in every later year). Argentina invests $192 in year 0 by borrowing from the rest of the world at a world real interest rate r* of 20%. There is no further borrowing or investment after this.
Use the standard assumptions: Assume initial external wealth W (W in year -1) is 0. Assume G=0 always; and assume I=0 except in year 0. Assume NUT= KA = 0 and that there is no net labor income so that NFIA = r*W.
The projects start to pay off in year 1 and continue to pay off all years thereafter. Interest is paid in perpetuity, in year 1 and every year thereafter. In addition, assume that if the projects are not done, then GDP=Q=C= $600 in all years, so that: PV(Q) = PV(C) = 600 + 600/0.20 = 3,600.
b) From this point forward, assume the projects totaling $192 are funded and
completed in year 0. If the MPK is 40%, what is the total payoff from the
projects in future years?
c) Assume this is added to the $600 of GDP in all years starting in year 1. In dollars, what is Argentina’s Q = GDP in year 0, year 1, and later years?
d) At year 0, what is the new PV(Q) in dollars? Hint: To simplify, calculate the
value of the increment in PV(Q) due to the extra output in later years.
e) At year 0, what is the new PV(I) in dollars? Therefore, what does the LRBC say is the new PV(C) in dollars?
f) Assume that Argentina is smoothing consumption. What is the percent change in PV(C)? What is the new level of C in all years? Is Argentina better off?
g) For the year the investment projects go ahead, year 0, explain Argentina’s
balance of payments as follows: State the levels of CA, TB, NFIA, and FA.
i) What happens in later years? State the levels of CA, TB, NFIA, and FA in year 1 and every later year.
