PART B: Analytical Problems
PROBLEM 1 (15 points)
Let the following represent the structure of a small open economy with a flexible exchange rate:
C = CA + 0.9(Y-T)
CA = 450-5r
T = 200+0.1Y
(M/P)D = 0.1Y-4r
MS/P = 1150
IP = 850-10r
G = 1350
NX = 730-0.06Y-100e
(a) Initially, assume that the foreign and domestic interest rates are equal, or that r = rf. You will solve
for these interest rates in part (b). Also let the foreign exchange rate e equal 2. Find the IS and LM
equations in terms of the domestic interest rate r. (4 points)
k = 1/[(1-0.9)(1-0.1)+0.1+0.06] = 4
AP = 450-5r-0.9*(200)+850-10r+1350+730-100*(2) = 3000-15r
IS: Y=k*AP = 4(3000-15r) = 12000-60r
LM: MS/P=(M/P)D => 1150 = 0.1Y-4r => Y = 11500+40r
(b) Find equilibrium output and the domestic interest rate. Set the foreign interest rate equal to your
answer for the domestic interest rate in this problem (Problem 1, part (b)). The foreign interest rate will
remain fixed at this value for the remainder of Problem 1. (2 points)
Solve IS and LM simultaneously,
12000-60r = 11500+40r
r= rf =5
Y = 11500+40(5) = 11700
(c) Now let the domestic interest rate diverge temporarily from the foreign interest rate. Suppose the
Government decreases money supply by 50. Compute the new equilibrium domestic interest rate r and
the new (temporary) equilibrium real output Y. (3 points) (HINT: Solve as in part (b) with the
original IS equation and the new LM equation)
New LM: 1100 = 0.1Y-4r => Y =11000+40r
New Temporary Equilibrium is 11000+40r = 12000-60r => r = 10%, Y = 11400
(d) Given the decrease in the real money supply above, compute the level of real output that equalizes
domestic and foreign interest rates. (3 points) (HINT: The foreign interest rate is the same as you
solved in Part (b). Given that interest rate, use the new LM curve to solve for output, since you
don't know what the IS curve is at this point.)
In a small open economy, the domestic and foreign exchange rates must be equal.
The final true equilibrium interest rate is 5 and output Y = 11000+40(5) = 11200.
(e) Find the new foreign exchange rate that equalizes domestic and foreign interest rates. (3 points) (
HINT: Find the new exchange rate that will make the IS curve shift to the left by enough to cross
the foreign interest rate at the same output level that you solved for in Part (d).)
Since the final true equilibrium (r, Y) equals to (5, 11200), the new IS curve must be as follows:
Y=4*Ap’-60r => 11200=4Ap’-300 => Ap’=2875
∆ Ap = 2875-3000 = -125 = -100 ∆e
=>∆e = 1.25
e’= 2+1.25 = 3.25
PROBLEM 2 (15 points):
(a)
Write down the numerical SP equation using the following information. Be sure to remember
that supply shocks enter into this. (2 points)
•
Expected inflation is given by the relation: pe = 0.68p-1 + 0.32pe-1
•
When the (log) output ratio increases by one point, inflation increases by 3 points.
p = pe + gŶ + z  p = 0.68 p-1 + 0.32 pe-1 + 3 Ŷ + z
(b)
Write down the DG equation (no need to derive anything, just write it down). (1 points)
Ŷ = Ŷ-1 + x̂ - p
(c) Find p as a function of p-1, pe-1, Ŷ-1, , and z. Show how you derive your result. (2 point)
p = 0.68 p-1 + 0.32 pe-1 + 3 Ŷ + z = 0.68 p-1 + 0.32 pe-1 + 3(Ŷ-1 + x̂ - p) + z
4p = 0.68 p-1 + 0.32 pe-1 + 3 Ŷ-1 + 3 x̂ + z
p = 0.17 p-1 + 0.08 pe-1 + 0.75 Ŷ-1 + 0.75 x̂ + z
(d) Complete the next two segments using the following information.
 Use the equations you derived above.
 In period 0, the economy is in long run equilibrium with x̂ = p-1 = pe-1 = 4 and z0 = 0.
 The economy experiences a supply shock in period one according to z1 = +2 and the supply
returns to zero in period two z2 = 0.
