2. A small open economy with perfect capital mobility is
characterized by the following equations:
𝑀𝑑 =3π‘Œβˆ’40𝑖 𝑃𝑑
𝑖𝑑 = π‘–βˆ— βˆ’ 𝑆𝑑+1βˆ’π‘†π‘‘ 𝑆𝑑
𝜎 = 𝑆𝑃 π‘ƒβˆ—
Assume 𝑀𝑑 = 60, π‘Œ = 11, π‘ƒβˆ— =
6 and π‘–βˆ— = 0.075. In the long run, purchasing power
parity holds so that 𝜎 = 1 .
a) Draw and explain the MM and the PPP curves (30%)
b) What is the long run equilibrium? (20%)
Suppose we are at this long run equilibrium but
now 𝑀𝑑 increases by 30 to 90.
c) What is the new long run equilibrium? Explain your answer
using a diagram. (20%)
d) What happens to the nominal exchange rate 𝑆𝑑in the short
run? Draw a diagram and explain what will happen. (30%)
